- 907 - Our Accidental Universe
Professor and presenter, Chris Lintott, talks about his new book Our Accidental Universe; a tour of chance encounters and human error in pursuit of asteroids, pulsars, radio waves, new stars and alien life. Even with incredible technological developments, the major astronomical events of the past century are largely down to plain ol’ good luck; discovered not, as you might assume, by careful experiment, but as surprises when we have been looking for something else entirely. For instance, the most promising habitat for life beyond Earth turns out to be Saturn's tiny moon Enceladus, whose oceans were revealed when NASA's Cassini probe did a drive-by and, we get the most from the Hubble Space Telescope by pointing it at absolutely nothing!
A new company has launched which aims to mine Helium-3 on the moon to sell on Earth. This rare isotope is used for supercooling quantum computers and some scientists dream of using it in nuclear fusion as a new source of renewable energy. But is this ambition realistic and, if so, could it be within reach anytime soon? Planetary scientist Sara Russell of the Natural History Museum explains all.
There are many moons in our solar systems, but one of the strangest is Titan; the largest moon of the Saturn system. It gets colder than 100 degrees Celsius and has a thick atmosphere that creates weather. But its biggest mystery is the enormous, coffee-coloured dunes that cover a large part of its surface. Where did they come from? Planetary scientist Bill Bottke has a cunning theory.
In our universe, some stars are twins. They originate from the same molecular clouds and should be identical, but some pairs are not as similar as you’d expect. Marnie speaks to astrophysicist Yuan-Sen Ting about his new paper which illuminates how this difference might occur. His theory is that one of the stars, perhaps the evil twin, has been busy eating up vulnerable planets...

Thu, 18 Apr 2024 - 906 - World’s oldest forest fossils
The world’s oldest fossilised forest was uncovered in Somerset last week. We head to palaeobotanist, Dr Christopher Berry’s, lab at Cardiff University to learn about these cladoxylopsids. They lived 390 million years ago and although they are not the ancestors of today’s trees, they reveal some extraordinary evolutionary secrets.
Also, Marnie speaks to Dr Chris Thorogood of the University of Oxford Botanic Gardens about his new book Pathless Forest: The Quest to Save the World’s Largest Flowers. Called “Rafflesia” plants and found in the remotest parts of South East Asia, their flowers burst from the rain forest floor the size of pumpkins and are critically endangered. Chris talks of his world of extreme fieldwork and hair-raising expeditions, braving leeches, lizards and lethal forest swamps, to discover the rarest of rare blooms.
Plus, the Wildlife Trust’s Making Friends with Molluscs campaign starts today, and I’m sure many gardeners will declare this an impossible task! We visit some allotments in Bristol to find out how people are managing slug and snail populations. And chat to Brian Eversham from the Trust of Bedfordshire, Cambridgeshire and Northamptonshire, who explains why these garden creatures should be considered our friends, not foes.
And finally, Dr Stewart Husband from last week’s programme returns to answer more of your burning questions about your tap water.
Thu, 11 Apr 2024 - 905 - Human Consciousness: Could a brain in a dish become sentient?
As the field of neuroscience advances, scientists are increasingly growing brain tissue to study conditions like autism, Alzheimer's and Zika virus. But could it become conscious? And if so, how far away is that scenario?
Wind, changing water temperatures and salt are all factors known to control ocean currents. But new research suggests there's another element in the mix. When sea monkeys amass, the thousands of swimming legs can create powerful currents that mix hundreds of meters of water.
Whenever a baby is born, we ask whether it's a girl or a boy. But when it comes to puppies, the question is often about the breed, especially with mongrels. And when we think we know what it is, we make assumptions about how that dog will behave. For instance, if you think there's some golden retriever parentage, you may expect it to be good at playing fetch. But do our perceptions of dog breeds change the way it behaves? That's the question of a new citizen science project called MuttMix, which asks you to guess the ancestry of various mongrels.
Finally, Charles Dickens is known as one of the best novelists of the Victorian era but a new exhibition is questioning whether he should be also known as a man of science. Dickens campaigned for paediatrics and his powers of description lead to a new conditions being medically recognised. The exhibition will be at the Charles Dickens Museum and it opens in May.
Thu, 26 Apr 2018 - 904 - Plastic-eating bacteria, Foam mattresses for crops, The evolved life aquatic, The Double Helix
A breakthrough for closed loop plastic recycling? Two years ago Japanese scientists discovered a type of bacteria which has evolved to feed on PET plastic - the material from which fizzy drink bottles are made It was isolated at a local recycling centre. An international team has now characterised the structure of the plastic-degrading enzyme and accidentally improved its efficiency. John McGeehan of the University of Portmouth led the team and talks to Adam about where the discovery may lead.
If you can't recycle plastic, you can re-use. Sheffield University chemist Tony Ryan is working to convert old polyurethane foam mattresses into hydroponic allotment beds so that people at a Syrian refugee camp in Jordan can grow their own crops. Roland Pease reports.
How southeast Asian sea nomads evolved the life aquatic.
The Double Helix, fifty years after its 1968 publication. Biologist and historian Matthew Cobb and science writer Angela Saini discuss the place of James Watson's compelling and controversial memoir in the annals of popular science writing. His account of the discovery of the DNA's structure was unlike any science book that had come before. Does it stand the test of time and what of its blantantly sexist treatment of the gifted X-ray crystallographer Rosalind Franklin? Her work was crucial to Crick and Watson's 1953 model of the DNA molecule.
Thu, 19 Apr 2018 - 903 - Pesticides in British Farming
A few weeks ago, Inside Science featured an item on neonicotinoids and the negative impact these pesticides have on insects like honey bees. The discussion turned to alternatives, including organic farming. Many listeners wrote in about some issues that went unchallenged. So this week, Adam returns to the subject to get into the nuts and bolts of both organic and conventional farming.
Next week sees the launch of a NASA mission called TESS. The Transiting Exoplanet Survey Satellite is surveying the brightest stars near Earth and looking for habitable planets. Roland Pease reports.
Traditionally, the move from Bronze Age to the Iron Age is estimated to be around 1200 BCE. But recent excavations of smelting sites in Uttar Pradesh in India suggest that this date might be a few centuries late and that it might even originate in Asia. Adam visits The Rutherford Appleton Laboratory in Oxfordshire to see how a particle accelerator is revealing the details of the Indian Iron Age.
Our ancestors bore a very prominent brow ridge, which scientists think was a symbol of dominance. Modern humans, however, have lost this ridge in favour of a flatter forehead. Why? Dr Penny Spikins and her colleagues think the answer lies in social interaction and in particular, the ability to raise your eyebrows.
Thu, 12 Apr 2018 - 902 - Stephen Hawking Tribute
Adam Rutherford presents a special tribute to the science of Stephen Hawking. He is joined by Fay Dowker, a former PhD student of Hawking and now a professor of theoretical physics at Imperial College, Professor Carlos Frenk, a long-time colleague and friend and fellow physicist and science communicator Professor Brian Cox. They look at the scientific legacy of Stephen Hawking and the role that his work played in bringing us a step closer to a single grand theory that explains how the universe works.
Thu, 05 Apr 2018 - 901 - Genes and education, John Goodenough, Caring bears and hunting
A widely reported study published last week suggests that on average children at selective schools have more gene variants associated with higher educational attainment than children at non-selective schools. It also suggests that selective schools achieve better GCSE exam results because their selection procedures favour children with those genetic variants, and not because of the teaching and facilities at private and grammar schools. Adam Rutherford talks to the senior researcher Robert Plomin of the Institute of Psychiatry in London, and Ewan Birney, director of the European Bioinformatics Institute near Cambridge.
John Goodenough invented the lithium ion battery, the power pack that makes our smart phones, tablets and laptops possible. At the age of 95, in his lab at the University of Texas, he's now working with colleagues such as Portuguese physicist Helena Braga on an even better next generation battery technology: one that could transform the prospects for electric vehicles and renewable energy storage. Roland Pease meets the jovial battery pioneer and his team.
Hunting regulations in Sweden are having a profound effect on the behaviour of brown bears in the country. Since the 1980s, hunters are not allowed to shoot female bears with cubs. Historically, mother bears stayed with their cubs for 1.5 years but as hunting rates increased, mothers began to keep their offspring with them for an additional year. Now more than a third of mothers look after their cubs for 2.5 years. According to Andreas Zebrosser of the University of Southeastern Norway and Joanie van der Walle of the Universitie de Sherbrooke, hunting appears to be acting as a powerful evolutionary force on the species' reproductive behaviour.
Thu, 29 Mar 2018 - 900 - Data Scraping
The story of how Cambridge Analytica had scraped Facebook data in its attempt to influence voting behaviour has been reported widely this week. Andrew Steele, a medical researcher at the Crick Institute in London, explains how data mining or scraping actually works and how it is used by many scientists to find ways of improving human health.
The Government Office for Science published a massive report this week, entitled the 'Future of the Sea' which sets out the UK's stall with regard to our future relationship with the seas, and to put science front and centre in that plan. Professor Ed Hill, Executive Director at the National Oceanographic Centre in Southampton, is one of the authors and tells Adam Rutherford about future exploitation of the sea.
Debris in space is a huge issue - it's estimated that there are more than 170 million fragments of satellites, rockets and other stuff that we've sent up, all orbiting the Earth at ballistic speeds. All of these have the potential to lethally strike a working satellite or worse, a crewed space station. Graihagh Jackson met Professor Guglielmo Aglietti at Surrey University who's researching the best technology to safely remove space junk.
Dinosaurs were incredibly successful and lived on earth for over 150 million years. Francois Therrien from the Royal Tyrrell Museum of Palaeontology in Alberta, Canada, and colleagues explored how living crocodiles and birds, the descendants of dinosaurs, rear their eggs. Dr Therrien told Adam how their findings have suggested that dinosaurs used a variety of ways to hatch their eggs in the many environments on earth.
Thu, 22 Mar 2018 - 899 - Buzz kill
As spring and Brexit loom, Adam Rutherford examines what stance the UK might take on neonicotinoids. The pesticide has been shown to harm bee populations by many scientific studies. Now, the largest report of its kind has put pressure on the EU to vote on whether three types of neonics should be banned. Will the UK follow Europe's lead if the ban is legislated?
Fly tipping is a problem faced by most authorities. But conservationists at the Creekside Discovery Centre in Deptford are embracing the carpets and shopping trolleys that have washed up in their creek in south-east London. They even argue that the rubbish provides a safe haven for wildlife. Graihagh Jackson investigates.
Graphene is often touted as a wonder material but now this carbon sheet could be making an unexpected appearance in your bathroom cabinet as hair dye.
The world-renowned physicist Stephen Hawking has died at the age of 76. The British scientist was famed for his work with black holes and a general relativity. Inside Science examines his scientific legacy.
Thu, 15 Mar 2018 - 898 - Russian Spy Poisoning
A former Russian spy, Sergei Skripal, and his daughter Yulia are in a serious condition after being exposed to a nerve agent on Sunday. The first police officer to attend the scene also remains in hospital. It is being treated as 'a major incident involving attempted murder.' We ask what happens next: what antidotes are available, how do they work and what's the prognosis?
Today marks International Women’s Day. Its aim is to celebrate the social, economic, cultural and political achievements of women. But there’s also a strong call for change, especially in the tech industry where women are vastly underrepresented. Discussions on how we could achieve gender equality have been ongoing for years, so why has there been so little change? And how can this bias affect the technology we all use?
Scientists are warning of an infertility 'crisis' among men. Sperm counts have been falling for over 40 years and now, 1 in 20 men have low sperm counts. The cause is unknown and this week, doctors are calling for more funding to better understand the issue.
The red squirrel has found an unlikely ally: the pine marten. Grey squirrels were introduced to the UK in the late 1800s from America and have since caused the native red population to diminish. However, with the reintroduction of a predator, the mal-adapted greys are being hunted and as a result, red squirrels are bouncing back.
Thu, 08 Mar 2018 - 897 - Weird Weather?
With many parts of the country seeing large snowfalls we ask what's driving our current weather? What factors need to be in place to create snowfalls, and how do these differ from sleet or frozen rain? And we address the impact of climate change, while a series of weather events might show a pattern, at what point should we go looking for explanations beyond natural events?
Dutch Elm Disease laid waste to millions of British Elm trees back in the 1970's, Now a new tree bacteria which mimics the effects of drought has spread from the Americas to Europe. It has already been detected in some tree imports to the UK. Unlike Dutch Elm Disease it affects a huge variety of trees and shrubs, from mighty oaks to fruit trees and Lavender bushes. New directives have just been introduced to try and halt its spread.
Can we beat dementia? Research from the US amongst people in their 80's and 90's provides grounds for optimism, showing that elderly people with good memories have brain structures which can be more developed than those of people 30 years younger. And yet at the same time they may carry factors usually associated with dementia.
And how violent are we? Compared with our past that is. Research from collections of gruesome medieval remains paint a picture of a violent society, where men and women commonly carried weapons and inflicting or receiving severe wounds may have been a part of daily life. And yet other studies suggest this level of violence is actually lower than that experienced in some societies today.
Marnie Chesterton presents.
Thu, 01 Mar 2018 - 896 - Science after Brexit
The UK is one of the largest recipients of research funding in the EU. Marnie Chesterton discusses what the future of UK science funding will look like with MP Norman Lamb, who chairs the House of Commons Science and Technology Committee, and Ed Whiting, Director of Policy and Chief of Staff at the Wellcome Trust.
Around 4,500 years ago, 90% of the British population was replaced by incomers known as the Beaker people. Across Europe archaeologists have uncovered elements of the Beaker culture - bell-shaped pots, copper daggers, arrowheads, stone wrist guards and distinctive perforated buttons -it's always been a mystery as to whether these finds represent a wave of mass migration or the sharing of ideas between peoples. Now ancient DNA studies show it was both, and for Britain reveal a huge population change which still resonates today.
A new collaboration between an artist and a cyclone physicist commences this week.They joined forces to model Hurricane Katrina and cast its shape into six brass bells. Each bell represents a key moment from the category 5 storm, as it progressed across the Gulf of Mexico and made landfall in the United States in 2005. The finished collection will feature in a BBC Radio 4 documentary later this year.
And how does the moon affect life on earth? specifically worms - we unearth a species of worm that times its mating ritual by the waxing and waning Moon.
Thu, 22 Feb 2018 - 895 - Shipping air pollution; Cheddar Man; Millirobots in the body;Dog brain training
Sulphur belched out of vessels' smokestacks is a serious health problem for coastal communities around the world. Four hundred thousand premature deaths from lung cancer and cardiovascular disease and around 14 million childhood asthma cases annually are reckoned to be related to shipping emissions. The International Maritime Organisation has finally agreed to drastically reduce polluting emissions from 2020. Gareth Mitchell discusses with James Corbett of the University of Delaware the impact of the emissions reduction on health.
The nearly complete skeleton of Cheddar Man was found in a cave in Somerset in 1903. He'e been in the news because experts in human face reconstruction have created an image of what he probably looked like based on new DNA evidence. Chris Stringer, Ian Barnes and Selina Brace of the Natural History Museum have all worked with Cheddar Man and they talk to Gareth about how the study of this 10 000 year old skeleton is part of a bigger project to understand how Britain became populated with waves of peoples from Europe in the Mesolithic and Neolithic eras.
Scientists at the Max Planck Institute for Intelligent Systems have invented a magnetically controlled soft robot only four millimetres in size that can walk, crawl or roll through uneven terrain, carry cargo, climb onto the water surface, and even swim in it. Professor Metin Sitti, Director of the Physical Intelligence Department at the Max Planck Institute, explains how it works and how he sees the future use of millirobots in medicine - in delivering drugs and targeting cancerous cells.
Marnie Chesterton talks to Dr Lisa Wallis from ELTE University in Hungary about her work to improve the cognitive abilities of older dogs... using touchscreens.
Thu, 15 Feb 2018 - 894 - Democracy in Space
This week a US based billionaire launched a giant space rocket and sent a car vaguely in the direction of Mars. As a space mission it was to say the least unconventional, and for those involved in promoting space science it presents a quandary. Is such a mission largely a publicity stunt or is it useful for engaging people in the potential of space exploration? Gareth Mitchell looks at one project which enables schoolchildren to programme computers on the International Space Station and he talks to the European Space Agency about why a rock concert might be a good avenue for exploring space science.
As more and more of our everyday lives are conducted online we ask what are the cyber-security threats of today, and how can science be used to counter them. Do we now need new kinds of science to locate, understand and stop new kinds of threat?
Can bat science help human ageing research? New findings have show that some long lived bat species do not age in the same way as other mammals. They don't even seem to posses the DNA repair enzyme most commonly found in the animal kingdom. We look at the mystery of why bats seem to have evolved in this way.
And have you lost a satellite? Don't worry: a computer geek will find it for you. That's exactly what's happened - an amateur space sleuth has detected signals from a NASA satellite thought to have been 'lost' for years.
Thu, 08 Feb 2018 - 893 - Scientists on Trial
In 2016 there was an attempted coup in Turkey. This led to many people who the government saw as opposition figures being sacked from their jobs and in some cases held without trial. They include prominent intellectuals, medics and scientists. In recent days there has been a similar crackdown on people voicing criticism of Turkey's current military actions in Syria. Stephen Reichter, Professor of Psychology at St Andrews University has been to Turkey to observe the trial of one of his former colleagues. He tells us what he saw and discusses the wider issues for science.
It's the 60 years since the launch of Explorer 1 and the discovery of the Van Allen Belts. This was the satellite the US launched in response to Sputnik. However unlike Sputnik it did undertake scientific exploration, its findings have been significant for every space mission that followed.
Using DNA sequencing scientists have found that the 'Two Brothers' mummies at the Manchester Museum have different fathers so are, in fact, half-brothers. Khnum-nakht and Nakht-ankh - date to around 1800 BC. Ever since their discovery in 1907 there has been some debate amongst Egyptologists on whether the two were actually related at all. DNA was extracted from their teeth to solve the mystery.
And the science of the Archers, a current storyline involves leaks of industrial chemicals illegally buried on a farm many years ago. We'll be looking behind the scenes to see where the story came from and how the world's longest running soap opera ensures scientific accuracy.
This week's programme is presented by Gareth Mitchell as Adam is away.
Thu, 01 Feb 2018 - 892 - Did typhoid kill the Aztecs, DNA stored in Bitcoin, Glow-in-the-dark plants and levitating humans
What killed the Aztecs? In some areas of the Americas, as many as 95% of the indigenous population died of diseases brought in by the discoverers of the New World. Pandemics hit the population who had little immunity to diseases carried by people and livestock. One outbreak responsible for killing millions started in 1545 and was locally called 'cocoliztli'. But for the last 500 years, exactly what this deadly disease was has remained a mystery. Adam talks to Johannes Krause of the Max Planck Institute who has analysed the teeth of 10 individuals from a mass grave for pathogens and found remnants of typhoid fever DNA. Could this be, in part, responsible for the deaths of millions? Historian Caroline Dodds Pennock from the University of Sheffield discusses the difficulties of knowing for definite what killed so many millions of people.
In 2015, Nick Goldman issued a challenge. If anyone could decode the information he had stored on some DNA by 21st January 2018, they could win a bitcoin. When Nick bought the bitcoin it cost about £200. To claim the bitcoin, the winner would have to sequence the DNA and then decrypt a code. In late 2017, Nick thought he would be keeping his bitcoin, now worth thousands of pounds. But PhD student Sander Wuyts got in touch with Nick to claim his prize. Marnie Chesterton follows the story.
Adam talks to MIT scientist, Michael Strano about his new techniques to make plants glow in the dark. Could these plants be used as street lighting in the future?
And how can sound be used to levitate humans? Professor of Ultrasonics at the University of Bristol, Bruce Drinkwater explains how his team have managed to overcome a size limit on the use of acoustic beams to trap and move objects in space. With no theoretical upper limit on the size of object which can be levitated, he explains how the technology could be used in medicine to deliver powerful drugs to a very specific place. This would leave the rest of the body unharmed or could help in the dispersal of kidney stones.
Thu, 25 Jan 2018 - 891 - African swine fever, Oil spill update, CRISPR gene editing, Rat eradication in New Zealand, Chimp kin recognition
African Swine fever is deadly to pigs and is spreading west from Russia across Europe. The virus that causes it is very resilient and can stick around on clothing, hay and in infected pork products for as long as 150 days. Biosecurity is crucial to preventing its arrival in the UK. If just one pig eats some infected meat from discarded human food the disease could quickly spread causing thousands of pigs to be culled and costing the industry millions. But what is the current progress on developing a vaccine? Adam talks to virologist Professor Jonathan Ball of Nottingham University and Zoe Davies from the National Pig Association.
Simon Boxall from Southampton Oceanography Centre gives an update on the sinking of the oil tanker Sanchi and its environmental impact.
CRISPR is a revolutionary gene editing technique which can modify DNA and has the potential to correct genetic errors in a range of human diseases - even cancer. The technique has only been around for a few years but is already being talked about as a Nobel prize winning candidate. The market for the technology has been predicted to be worth US$ 10 billion by 2025. But stocks took a wobble last week on news that our immune system may render CRISPR useless. Is there really a big problem? Adam talks to Matt Porteus from Stanford University who did the research.
18 months ago, New Zealand announced a conservation project to exterminate all vermin that are decimating the indigenous bird population. For millions of years, the flora and fauna evolved in isolation, without predatory mammals. When humans arrived, they brought with them a host of bird-eating animals like rats, stoats and possums which now kill 25 million native birds every year. Marnie Chesterton travelled to New Zealand to report on a campaign of mass poisoning to save the kiwis and the kakapos and asks whether it’s ethical to kill one species to save another.
And Cat Hobaiter from St Andrews University responds to listener questions about how chimpanzees might recognise family members.
Thu, 18 Jan 2018 - 890 - Sanchi oil tanker, Gut gas-monitoring pill and Chimpanzee portraits
After the Sanchi oil tanker collided with another ship it discharged its cargo of 1 million barrels of condensate oil. This could cause one of the biggest oil disasters in 25 years. What is condensate, can it be cleaned up and how toxic to marine life is it if large amounts of it leak or the tanker sinks? Adam talks to Simon Boxall from Southampton Oceanography Centre.
A long-held belief that babies look more like their fathers is being put to the test by scientists at St Andrews University. They are launching an on-line citizen science experiment asking members of the public to see if they can tell from a group of chimps which are the close relations. Geoff Marsh takes the test and talks to researcher Cat Hobaiter about why it might be advantageous for a baby primate to look like its father more than its mother and what they hope to learn from humans' ability to recognise chimp family trees.
A new swallow-able, electronic pill that sniffs out the gas produced in your gut could be the answer to accurately diagnosing and distinguishing between ailments of the gut. The gastrointestinal tract is hard to access so when something goes wrong, conditions like Irritable Bowel Syndrome, lactose intolerance and over production of bacteria. can be hard to distinguish from one another and so accurately diagnosed. Professor Kourosh Kalantar Zadeh from RMIT in Melbourne explains why his device, which senses gases in the gut and transmits its findings back to a smartphone in real time,, is more accurate and less invasive than current breath tests or endoscopies and colonoscopies.
And Janet Kelso answers listener questions on human evolution and why modern Europeans still carry Neanderthal DNA.
Thu, 11 Jan 2018 - 889 - Tabby's Star, Space 2018, Mosquito sounds, C diff and food additive link
Adam Rutherford talks to astronomer Tabetha Boyajian at Louisiana State University about the wierd star that's perplexed astronomers since its discovery two years ago. KIC 8462852 has the unique habit of intermittently and sometimes dramatically dimming and then brightening. Some scientists even suggested vast alien megastructures around the star might be the explanation. After twenty months of almost continuous observation, Professor Boyajian has much more information about what the star is doing. But the big mystery hasn't gone away.
BBC News science correspondent Jonathan Amos joins Adam to share some highlights in space exploration for the coming 12 months.
Zoologists and engineers at the University of Oxford are developing an app that identifies one species of mosquito from another by analysing the sounds their rapid wing beats make. Graihagh Jackson visits Marianne Sinka at the Zoology Department to listen to her collection of mosquito songs.
Did the widespread introduction of the food additive trehalose fuel the emergence of epidemics of virulent Clostridium difficile in hospitals from the early 2000s? Microbiologist Robert Britton tells Adam about the evidence his team has gathered and published this week in the journal 'Nature'.
Thu, 04 Jan 2018 - 888 - Ancient DNA and Human Evolution
Twenty years ago, a revolution in the study of human evolution began. A team in Leipzig in Germany successfully extracted DNA from the bones of a Neanderthal man who died about 40,000 years ago. Thirteen years later, the same group unveiled the first complete genome sequence of another Neanderthal individual. Last year, they announced they'd retrieved DNA from much oldest archaic human bones, more than 400,000 years old.
Adam Rutherford talks to Svante Paabo, the scientist has led these remarkable achievements. Professor Paabo and his colleague Janet Kelso at the Max Planck Institute of Biological Anthropology in Leipzig discuss the genes in many European people alive today that originated in Neanderthals and were passed to modern humans when the two species interbred.
Adam also speaks to Johannes Krause who worked on the Neanderthal genome project in Leipzig but is now director of the Max Planck Institute of the Science of Human History. His latest research adds a new layer of intrigue and complexity to the relationship between our species and Neanderthals in deep time.
David Reich at Harvard University focuses on using ancient DNA to uncover the ancestry and movements of modern human hunter-gatherers in Eurasia from about 50,000 years to the Bronze Age, a few thousand years ago. Population movements occur on a cinematic scale, he says. (Podcast only).
The revelations of ancient genetics would not be possible and meaningful without the traditional disciplines of palaeoanthropology and archaeology. Adam goes to Gibraltar to seek the perspective of Clive Finlayson who leads excavations there as director of the Gibraltar Museum. Gibraltar is the most concentrated site of Neanderthal occupation in the world. As well as remains of a young Neanderthal child last year, the Rock's caves have also recently yielded the first example of Neanderthal cave art.
Thu, 28 Dec 2017 - 887 - Antisense RNA therapy, Fossils vs Trump, Printing mini-kidneys, Electric eel power
Promising results from a small clinical trial of Huntingdon's disease patients have led to RNA-directed therapy such as antisense RNA being hailed as possibly a turning point in the treatment of neurodegenerative diseases. Adam Rutherford discusses this class of drugs with Heidi Ledford of Nature News.
At the beginning of the month, Donald Trump decreed that two national monument landscapes be drastically down-sized. Strict protections against exploitation were removed from vast tracts of land bearing some of the world's most important fossil bearing strata. President of the Society of Vertebrate Paleontologists, Professor David Polly explains why his organisation is now suing Trump.
At Harvard University, bioengineers are growing parts of functioning kidneys in small chips using a form of 3D printing. Jennifer Lewis' lab is doing this to learn how kidneys function and explore the possible therapeutic applications of the mini-kidneys-in-a-chip. Roland Pease visits the team at work.
The electric eel can deliver a 600 volt shock, from a stack of electrically charged cells along the length of its body. Inspired by the eel's biology, Michael Mayer and his colleagues at the Universities of Fribourg and Michigan have now created their own version of its electric organ with the help of jelly babies and clever origami. In the future, it could power devices in the human body.
Thu, 21 Dec 2017 - 886 - The Future of Coral Reefs, Little Foot, Arthur C Clarke
Oxford is hosting the European Coral Reef Symposium this week. Climate change is seen as the number one threat to the future of coral reefs. Adam talks to Morgan Pratchett of James Cook University about the two recent coral bleaching events that hit the Great Barrier Reef, and to Barbara Brown of Newcastle University about the potential for coral species to adapt to warmer seas.
After twenty years of excavation and preparation, the most complete fossil skeleton of an Australopithecine has been unveiled to the public in South Africa. Its discoverer Ron Clarke explains its significance for understanding human evolution.
December 16th is the 100th anniversary of Arthur C Clarke. Science writer Marcus Chown and cultural journalist Samira Ahmed join Adam to discuss Clarke's visions and works of science fiction.
Thu, 14 Dec 2017 - 885 - Trophy hunting, Gene drives, Nuclear lightning, Peregrine falcons and drones
Trophy hunters are always after the lion with the largest darkest name and the stag with the most impressive antlers. Research by Rob Knell at Queen Mary University of London finds that removing a small proportion of these top males can drive whole populations to extinction, if their environment is changing.
Gene drive is a new genetic technology that could be used to eradicate populations of species of 'pest' animals. The Roslin Institute in Edinburgh has just announced it is to begin research on gene drives to control rat and mouse populations. The Institute's Bruce Whitelaw and Simon Lillico explain how the approach would work and argue that it would be humane compared to traditional methods of vermin control. However there are concerns about its potential ecological consequences - namely the risk of female infertility in the targeted species spreading without no geographical limits. Kevin Esvelt of MIT voices his reservations. Bruce Whitelaw outlines how future research aims to bring gene drives under more control.
Researchers in the USA and Japan talk about their discovery of nuclear reactions in lightning strikes, and Caroline Brighton and Graham Taylor of the University of Oxford explain why they have been attaching small cameras and GPS units to peregrine falcons and recording the birds chasing drones.
Thu, 07 Dec 2017 - 884 - Prehistoric Strong Women, Semi-synthetic Life, Listener Feedback, Artificial Superintelligence
More than 5,000 years of heavy agricultural labour by women can be read from the bones found in ancient cemeteries from the Neolithic to Iron Age times. Cambridge University anthropologist Alison Macintosh compared the arm bone dimensions and strength of women from these times with those of modern female athletes such as runners to rowers. Her conclusion is that average upper body strength of women through the Neolithic to the Iron age times exceeded that of today's semi-elite female rowers.
A laboratory at the Scripps Research Institute have created a semi-synthetic bacterium with two new man-made genetic letters in its DNA, in addition to the natural four A, G, T and C. What's more, the engineered microbe can use its enhanced genetic alphabet to build synthetic amino acids into the proteins it makes. Chemist Floyd Romesberg talks to Adam Rutherford about what we can learn from his team's extraordinary feat of synthetic biotechnology, what we might gain from it and why, in his opinion, we've no need to be worried.
Adam deals with some of your correspondence on axolotls by talking to laboratory salamander breeder Randal Voss at the University of Kentucky. He also notes listeners' comparisons of the recent visit by interstellar asteroid Oumuamua with the alien vessel in Arthur C Clarke's 'Rendezvous with Rama'.

Thu, 30 Nov 2017 - 883 - Interstellar visitor, Svante Paabo, Synthetic biology, Plight of the Axolotl
On 19th October, a mysterious object sped through our solar system. It was first spotted by astronomers with a telescope in Hawaii. Its trajectory and speed told of its interstellar origins. It is the first body to be detected from outside our solar system. Scientists are now publishing their papers on the enigmatic visitor. They estimate that it was about 400 metres long and bizarrely elongated in shape. Adam Rutherford talks to astronomer Alan Fitzsimmons of Queens University in Belfast.
Twenty years ago, geneticist Svante Paabo began a revolution in human evolution science when he extracted fragments of DNA from the 40,000 year old bone of a Neanderthal. Among other first, he went onto sequence the entire genome sequence of Homo Neanderthalenisis. Professor Paabo was in the UK this week at a conference on DNA and human evolution at the Wellcome Genome Campus to mark the anniversary. He tells Adam about one of the new directions of research for him now.
What does the future hold for synthetic biology? Who will be the practitioners of this fast-growing branch of bioengineering and what will be its impact on the world - for good and possibly ill? Experts in the field have just published a horizon-scanning report in the journal eLife. One of its authors, Jenny Molloy of the University of Cambridge, talks to Adam about the nascent democratisation of the discipline and where this might lead the field and society.
The paradoxical plight of the axolotl: popular aquarium pet, laboratory animal and critically endangered species in the wild. This species of salamander is a wonder of nature. It's the amphibian that never grows out of its larval stage yet it's able to reproduce. Most remarkable is its ability to regrow limbs, which is of great potential interest to researchers developing regenerative medicine. There are many thousands of axolotls in labs and homes around the world. But in the wild, in their native Mexico, they are on the very edge of extinction. Inside Science talks to conservation biologist Richard Griffiths of the University of Kent and axolotl researcher Tatiana Sandoval Guzman of the Technical University in Dresden, Germany.

Thu, 23 Nov 2017 - 882 - Can we forecast earthquakes?, Britain's space race rocket Skylark, Francis Galton
What might the length of the day have to do with the likelihood of destructive earthquakes around the world? According to Professors Rebecca Bendick and Roger Bilham, there's a correlation between changes in the rate at which the Earth rotates and the incidence of earthquakes of Magnitude 7 and above. The rotation speed of the planet increases and decreases over periods of years and decades. From their research, the earth scientists say that there's an substantial increase in the number of powerful earthquakes around the world five years after the Earth attains a peak in its spin speed and enters a period of slow down. The difference in day length is tiny but it is enough, say the researchers, to trigger already stressed faults in the crust to move sooner than later.
In the year that the Soviet Union launched Sputnik into orbit, the UK launched its own rocket into the Space Race. 1957 saw the launch of the first Skylark space rocket. Inside Science talks to two veterans of the Skylark programme - Professors John Zarnecki and Ken Pounds - who cut their space research teeth with some of the 440 launches. The Science Museum in London is staging a Skylark exhibition in celebration.
Francis Galton was one of the UK's most influential 19th century scientists and laid important methodological foundations for genetics and other fields of science today. But he was also a racist and leading proponent of eugenics. Adam discusses Galton's legacy with historian Subhadra Das of University College London and clinical geneticist Han Brunner of the Maastricht University Medical Centre in the Netherlands. Both guests attended a meeting of the Galton Institute in London which brought together researchers of many disciplines to discuss the bad and the good in Francis Galton's legacy.

Thu, 16 Nov 2017 - 881 - Boy gets New Skin, The York Gospels, Stephen Hawking's Thesis
Researchers in Italy and Germany have saved the life of a boy with a life threatening genetic skin disease, using a combination of stem cell and gene therapy. 7 year old Hassan had lost 60% of his protective epidermis because of the condition, junctional epidermolysis bullosa. The severe blistering and consequent bacterial infections put his life in imminent danger. In a final attempt to save him, the scientists took a small area of unblistered epidermis from his body, separated the constituent skin cells and then engineered them with a normal version of the gene that was malfunctioning in Hassan's body. Sheets of healthy epidermis of an area of about one square metre were then grown in culture, and then grafted onto 80% of his body. Hassan is now living a normal life, back at school, playing football. Lead researcher Michele de Luca describes the remarkable recovery and Fiona Watt, director of the Centre for Stem Cell and Regenerative Medicine at Kings College London, explains how the procedure worked.
Scientists at the University of York are investigating medieval livestock farming through the study of the 1,000 year old York Gospels manuscript: not by reading it but by extracting proteins and DNA from its animal skin parchment pages.
Inside Science listener and Middle Eastern archaeologist Melissa Sharp takes the programme to task for suggesting that anyone can now use publically available sonar and satellite data to search for shipwrecks and other archaeological sites. It opens up the world's ancient and not so ancient heritage to looters, she says.
Since the University of Cambridge made Stephen Hawkings 1966 PhD thesis free to view and download last month, more than a million people have at least looked at it. Adam Rutherford talks to cosmologist Andrew Pontzen, biologist Matthew Cobb and neuroscientist Sophie Scott about the record-breaking thesis and asks whose first research project they'd like to download.

Thu, 09 Nov 2017 - 880 - Climate Change and Health; Moth Snow Storm Feedback; Whale Brain Evolution; Pharoah's Serpent
Adam Rutherford talks to researchers on a major global study that aimed to quantify how climate change has already damaged the health of millions of people. Hugh Montgomery is the co-chair of the Lancet Countdown report and says that climate change is the largest single threat to global health. Climate scientist Peter Cox talks about his stark findings on the increase in the number of vulnerable people exposed to heat waves between now and the turn of the century.
We hear anecdotes and concerns from listeners following our item last week on the catastrophic decline in flying insects in the last quarter century and the disappearance of moth snow storms.
What can the social lives and brains of whales and dolphins tell us about the evolution of our species cognitive capacities and white matter? Adam talks to Susanne Shultz of the University of Manchester.
Everyone's favourite indoor firework, the Pharoah's Serpent, is under scientific scrutiny from chemists Tom Miller and Andrea Sella at University College London.
Thu, 02 Nov 2017 - 879 - Insects disappearing, DNA Biosensor, Dog faces, Bandit dinosaur
The total biomass of flying insects in the environment has decreased by 75% in the last quarter of a century. That's the conclusion of research published at the end of last week in the journal PLOS One. The discovery, made in Germany, has shocked many, but should we in the UK be worried too? The answer is yes, according to Adam Rutherford's guests Dave Goulson, professor of biology at the University of Sussex, and Michael McCarthy, environmental journalist and author of 'The Moth Snow Storm.'
The speed and ease of precise infection diagnosis could be transformed by synthetic biologists at Imperial College, London. Paul Freemont tells Adam about a simple DNA biosensor that turns green in the presence of a pneumonia-causing bacterium that is a particular problem for people with Cystic Fibrosis. He adds that the technology is adaptable to any kind of bacteria and may also aid efforts to curb the spread of antibiotic resistance.
When dogs know you are looking at them, they ramp up the expressiveness of their faces. Marnie Chesterton visits the Dog Cognition Centre at the University of Portsmouth to talk to the researchers who made this discovery, and to meet Jimmy the Staffy.
Palaeontologists at the University of Bristol have figured out the colour patterning on a dinosaur that lived 120 million years ago. Sinosauropteryx was a small feathered dinosaur. Two spectacular fossils of it were found in northeast China. The specimens are so well preserved that remnants of pigment remain in the feathers. This allows Jakob Vinter and colleagues to see that Sinosauropteryx was reddish brown in colour, with light stripes on its tail, light and dark counter-shading on its body and a dashing bandit-style face mask.

Thu, 26 Oct 2017 - 878 - Colliding Neutron Stars, Krakatoa, Centigrade vs Celsius
Adam Rutherford talks to astrophysicists about the astronomical discovery of the year, if not the last couple of decades: the collision of two neutron stars and the cosmic gold-forging aftermath. The discovery of this long-hypothesized event on 17th August came from the much awaited marriage of the capabilities of the gravitational wave detectors LIGO and Virgo with those of ground-based and space-based telescopes. Samaya Nissanke of Radboud University, Sheila Rowan of the University of Glasgow and Nial Tanvir of the University of Leicester take Inside Science through the story.
What made the infamous 1883 eruption of Krakatoa so devastating? Roland Pease meets the earth scientists trying to answer the question by recreating in the lab the conditions under the volcano prior to the eruption.
Following a temperature-related faux pas by Adam in the last episode, Michael de Podesta of the National Physical Laboratory explains the difference between Celsius and Centigrade.

Thu, 19 Oct 2017 - 877 - HiQuake, Plate Tectonics@50, Sonic Weapon Puzzle, The Chinese Typewriter
Gareth Mitchell talks to Gillian Foulger of Durham University about HiQuake, the world's largest database of human-induced earthquakes. Professor Foulger and her colleagues have so far compiled close to 750 seismic events for which there are reasonable cases to be made for anthropogenic triggers. Triggers include mining operations, fossil fuel extraction, reservoir filling, skyscraper construction and tunnelling. Among the surprises is the fact that the US state of Oklahoma is more seismically active than California because of quakes and tremors set off by the local oil and gas industry.
The theory of plate tectonics is 50 years old. It's as fundamental to understanding the Earth as evolution by natural selection is to understanding life. Roland Pease meets geologists such as Dan McKenzie, John Dewey and Xavier Le Pichon who played key roles in proving the hypothesis in the late 1960s.
The United States has removed more than half of its diplomats from its embassy in Havana, Cuba. A signficant number of staff have complained of ailments such as hearing loss, dizziness, headaches and nausea, and there has been speculation that some kind of sonic or acoustic weapon might be responsible. Trevor Cox, professor of acoustic engineering at the University of Salford, discusses the likelihood with Gareth.
Stanford University's Tom Mullaney is the author of 'The Chinese Typewriter: A History'. He talks to Gareth about the great engineering and linguistic challenge in the 19th and 20th centuries of getting the Chinese language onto a table top machine. The survival of the ancient language or China's entry into the modern world depended on the success of numerous inventors. In fact one consequence was the development of predictive text in the Chinese IT world long before it appeared in the West.
Note: In the podcast version of this programme, there is an additional item on new research on the role of the world's botanical gardens in global plant conservation. One of the scientists involved, Dr Paul Smith of Botanical Gardens Conservation International, tells Gareth that there's good news about these institutions' contributions and there are areas where there is room for improvement.

Thu, 05 Oct 2017 - 876 - Gravity wave breakthrough, The antibiotic pipeline, Microbial waste recycling, Fausto - an AI opera
The gravitational waves produced by two massive black holes colliding have for the first time been detected by three gravitational wave detectors. Professor Sheila Rowan of the University of Glasgow explains the importance of this new three way observation.
The World Health organisation reports that there are too few new candidate antibiotics in the development pipelines to replace those becoming obsolete through the rapid spread of antibiotic resistance. Professor Willem van Shaik of the University of Birmingham and pharma-biotech analyst Dr Jack Scannell discuss where the problems and solutions might lie.
Could bacteria recycle all of our waste? Waste disposal is a growing concern as nations run out of space and ecosystems are increasingly polluted. Microorganisms may hold the key for turning household waste into biodegradable plastic and perhaps one day even into food and basic chemical feedstocks. Hans Vesterhoff, Professor of Systems Biology at Amsterdam University is developing microbial networks with the aim of converting all carbon-based waste into useful or edible stuff.
AI and Opera: Prof Luc Steels, an AI and language researcher at the Institute for Advanced Studies of Catalonia is also a composer. He has just had his new opera premiered. With a libretto written by a neuropsychiatrist colleague, the opera 'Fausto' is a re-telling of the Faust story. It explores the dangers and flawed thinking of silicon-based transhumanism. In the opera, the Faust character is a social media-obsessed hipster and Mephistopheles is a malevolent AI in the cloud. In a twist on the original, Fausto trades his body rather than his soul so that he can be uploaded and reunited with his lover in the cloud.
Thu, 28 Sep 2017 - 875 - Cassini's finale; Science and Technology Select Committee; Crick's lecture; Cave acoustics
After last week's Inside Science's edition devoted to Cassini ended, the Cassini spaceship plunged into the atmosphere of Saturn, and became part of the planet it studied. But the project lives on, as the data and photos generated by Cassini right up until contact was lost will be studied and scrutinised for years to come. Linda Spilker is the Project Scientist for the Cassini mission. Adam Rutherford spoke to her to find out what was captured in the last few moments of Cassini's closest and fatal encounter with the ringed planet.
The House of Commons has announced its Science and Technology Select Committee - the body of MPs that holds the Government to account on scientific matters, and offers advice on scientific issues of the day. Some controversy has followed, concerning the scientific credentials and the gender imbalance of the committee make-up so far. Norman Lamb, MP for North Norfolk was elected chair of the committee, and he came into the Inside Science studio to discuss the committee selection and its future ambitions.
This week was the 60th anniversary of one of the greatest conceptual leaps in all biology, made by Crick at a lecture at University College London. Matthew Cobb, biologist and historian from Manchester University, who's written a new account of the lecture, discusses its fundamental significance.
It has long been suggested that there's something about the acoustics of a cave that correlates with the location of motifs and sometimes paintings on the walls.Bruno Fazenda is an acoustic scientist at the University of Salford, and reveals how he went into the caves to conduct the first methodical study of this theory by listening to the past.
Thu, 21 Sep 2017 - 874 - Farewell to Cassini, the epic 20 year mission to Saturn
As Cassini's epic journey to Saturn finally ends tonight, Adam Rutherford celebrates the incredible discoveries of a mission that has changed the way we see our solar system. BBC Science Correspondent Jonathan Amos is at Mission Control in Pasadena as scientists assemble to witness the final few hours of the Saturnian observations beforeCassini completes its death dive into the planet. We also hear from key scientists who've played a role in capturing and interpreting the multitude of data from the last 12 years.

Thu, 14 Sep 2017 - 873 - North Korea Bomb Tests, Warming Antarctic Sea Life, the Microbiome, Cuckoo Chuckle
The Democratic People's Republic of Korea claims to have successfully tested a thermonuclear weapon, a hydrogen bomb. Tom Plant, director of Proliferation and Nuclear Policy at the Royal United Services Institute, talks to Adam Rutherford about how the boast might be proved by monitoring technology around the world.
How will marine life respond to warming of the seas around Antarctica this century? Dramatically, according to the results of the most realistic attempt so far to warm the sea bed to temperatures predicted for the coming decades. The British Antarctic Survey installed gently heated panels at 12 metres depth off the West Antarctic coast to mimic rock surfaces and then over 9 months monitored how marine creatures colonised and grew on them. All creatures flourished on panels at 1 degree C above today's chilly waters and in fact grew astonishingly quickly on them. But a 2 degree increase saw some continue to flourish vigorously but many species fail. Experiment mastermind Lloyd Peck tells Adam what the findings may mean, and describes the extraordinary cold water diving skills that made the experiment a success.
'I contain Multitudes' is shortlisted for the Royal Society Insight Investment Science Book Prize this year. Its subject is the microbiome - the trillions of benign , friendly and not so friendly bacteria which inhabit our bodies and those of all other animals.
For 30 years, Cambridge University zoologists have studied the evolutionary arms race between the cuckoo and the reed warbler that rears the cheating bird's offspring. They have figured out many of the deceptions and counter-tactics adopted by the two co-evolving species. The latest revelation concerns the strange chuckling call which the female cuckoo makes after laying her egg in the warbler's nest. Jenny York describes the experiments which show that the cuckoo is mimicking a predatory sparrow hawk which distracts the warblers and makes them much more likely to not recognise her egg as something they should reject from the nest.
Thu, 07 Sep 2017 - 872 - Noxious haze over south coast; In Pursuit of Memory book; technosphere; Big Wasp Survey
Last weekend a chemical ‘haze’ on the East Sussex coast saw 150 people needing hospital treatment after something in the air led to streaming eyes, sore throats and nausea. Leading theories so far include a chemical spill from shipping in the English channel, a localised spike in ozone levels and an algal bloom, where algae suddenly proliferate and release harmful gasses. Dr Simon Boxall of the National Oceanography Centre at the University of Southampton tells Gareth Mitchell why he’s favouring the algal bloom theory.
We know about extinct species from fossils in rocks. But in the future there will be techno-fossils too, evidence of our civilisation. Katie Kropshofer has been finding out from Professors Jan Zalasiewicz and Sarah Gabbot of the University of Leicester what we’re leaving for the hypothetical geologists of the future.
Neuroscientist Joseph Jebelli's book, In Pursuit of Memory: The Fight Against Alzheimer's, is the one of the six titles on the shortlist of the Royal Society Insight Investment Science Book Prize. He explains to Gareth Mitchell that it was his grandfather's development of the condition that made him interested in Alzheimer’s.
The Big Wasp Survey is a citizen project to trap wasps and send them off to teams at the University of Gloucester and University College London, so that scientists can then learn more about the distribution of different species around this land. One of the organisers, entomologist and professor of Science Communication at the University of Gloucester Adam Hart, talks to Gareth about why these unpopular insects are ecologically valuable.
Thu, 31 Aug 2017 - 871 - Killer robots; Myths and superstitions and conservation; Science book prize nominee - Cordelia Fine; Taxidermy
Once again, the ethical side of fully autonomous weapons has been raised, this time by over 100 leading robotics experts, including Elon Musk of SpaceX and Tesla, and Mustafa Suleyman of DeepMind. They have sent an open letter to the United Nations urging them to take action in order to prevent the development of "killer robots". The letter says "lethal autonomous" technology is a "Pandora's box", once opened it will be very difficult to close - they have called for a ban on the use of AI in managing weaponry. Gareth asks AI expert, Professor Peter Bentley from University College London, if this is the right approach or is this just an attempt to delay the inevitable?
When a paper titled "Fantastic Beasts and Why to Conserve Them" is printed in the journal Oryx, we had to take a closer look. Far more than a publicity stunt, this work by George Holmes, an expert in conservation and society at the University of Leeds, covers an important point. It explores the dangers of neglecting local beliefs, myths and superstitions about the natural world, and animals in particular, when trying to come up with conservation strategies.
Cordelia Fine is a professor of the history and philosophy of science at the University of Melbourne. She is the third shortlisted author of the Royal Society Insight Investment Science Book Prize. Her book "Testosterone Rex" explores the science behind gender. She argues that testosterone isn't necessarily the basis for masculinity and that there is so much more to gender than merely our biological sex.
200 years ago, taxidermy was a crucial part of zoological teaching and research, and in the days before BBC wildlife films, often the only way that many people could see strange and exotic wildlife from other lands. Lots of those early specimens are incredibly valuable, and can still be found in museums around the world, although being so old they are often in need of urgent repair. Usually this happens out of sight behind the scenes, but not so at the Grant Museum of Zoology in London, which has been doing its conservation live in the gallery for all to see, to draw attention to the art and science of taxidermy. Some of the more serious repairs get sent to taxidermy conservator Lucie Mascord in Lancashire.

Thu, 24 Aug 2017 - 870 - Antarctica's volcanoes, science book prize nominee - Mark O'Connell, US solar eclipse and 40 years of NASA's Voyager mission
Not so much hiding in plain sight, but tucked under the ice-sheet in Antarctica are 91 volcanoes. This adds to the 47 volcanoes already known on the continent. After a graduate student posed the question,"are there any volcanoes in Western Antarctica?", Dr Robert Bingham, and colleagues, at Edinburgh University, scoured the satellite and database records to find the volcanoes. This huge region is likely to dwarf that of East Africa's volcanic ridge, which is currently the most volcano-dense region on Earth.
Journalist Mark O'Connell is the second of our Royal Society Insight Investment Science Book Prize 2017 nominees. His broad-minded, yet sceptical look at the world of 'transhumanism', "To be a Machine: Adventures Among Cyborgs, Utopians, Hackers, and the Futurists Solving the Modest Problem of Death", questions how and why some of us are looking to use technology to fundamentally change the human condition.
On Monday 21st of August 2017, some of the United States will go dark. This is the first total solar eclipse, visible from coast to coast in the US for 99 years. Gareth gets excited with veteran eclipse watchers, David Baron and Jackie Beucher.
On the 20th of August 1977, NASA's probe Voyager 2 launched. This was quickly followed two weeks later by the launch of Voyager 1 (which was on a faster trajectory). Since then the two spacecraft have been exploring our Solar System, the Heliosphere and interstellar space. Surpassing all expectations, the probes have taught us so much about our planets, their moons and beyond. Gareth looks back at the highlights with the Voyager mission's chief scientist, Professor Ed Stone, in a celebration of the 40 year mission.

Thu, 17 Aug 2017 - 869 - European heatwave and climate change, Eugenia Cheng, Next generation batteries for electric cars, Joseph Hooker exhibition.
The current heat wave in Europe is proving deadly. High day and night temperatures, coupled with high humidity, can be a very dangerous combination. A new study has calculated the risk of deadly heat on a global basis, and shown that between 48% and 74% of the world's population will be subjected to life-threatening heat and humidity for at least 20 days a year. Ed Hawkins, Professor of Climate Science at the University of Reading, discusses the findings. Gareth also asks BBC weatherman, Darren Betts, whether the recent wave of climate trend animations, or gifs, doing the rounds on social media, are a helpful tool in communicating climate change risks.
Professor of Mathematics, Eugenia Cheng, is one of the shortlisted authors for the Royal Society Insight Investment Science Book Prize 2017. She talks Gareth through the inspiration for her book "Beyond Infinity: An expedition to the Outer Limits of the Mathematical Universe".
The UK Government announced last week that it was aspiring to remove all petrol and diesel vehicles from roads by 2040. Current battery technology relies on lithium-ion batteries. Are lithium, and the other metals required for batteries, sustainable for a totally electric transport system? And do they have the charge capacity to make them a reliable alternative to fossil fuels? Dr Billy Wu, of the Dyson School of Design Engineering at Imperial College London, goes through the alternatives and the next generation of battery technology.
To mark the 200th anniversary of the birth of one of Victorian Britain's most important scientists, Joseph Hooker (1817-1911), Kew Royal Botanic Gardens is holding an exhibition titled Joseph Dalton Hooker: Putting plants in their place. It's a fascinating selection of his photographs, journals and paintings. Gareth is taken on a tour by the curators - historian Professor Jim Endersby of the University of Sussex and Galleries and Exhibitions Leader at RBG Kew, Maria Devaney. They explain how as a tireless traveller and plant collector, Hooker was the founder of modern botanical classification and a close friend of Charles Darwin.

Thu, 10 Aug 2017 - 868 - Gene-editing human embryos, Spaceman's eyes, Science book prize, Sexual selection in salmon
Hypertrophic cardiomyopathy is the heart condition that can lead to seemingly super-fit athletes collapsing with heart failure. It affects one in 500 people, and is a heritable disorder. Scientists using the precise gene-editing technique, Crispr CAS 9, have identified one of the genes responsible for the disease and 'fixed' it. This is in very early stage human embryos, prior to implantation. Dr. Fredrik Lanner at the Karolinska institute, is a leader in this field and he describes the work as purely at the experimental stages, but the team have managed to overcome various issues with the technique.
Despite the obvious benefits of being an astronaut... exploring new worlds, seeing Earth from space, and of course the glory and fame, it can take a real toll on the body. Astronauts' skeletons and muscles deteriorate in zero gravity, their immune system weakens, and they experience nasal congestion and sleep disturbance. Many symptoms persists once they're back on Earth. But, there's another to add to the list, space flight-associated neuro-ocular syndrome or SANS. Ophthalmologist at Houston Methodist Hospital, Dr Andrew Lee explains that the build-up of fluid in the brain can squeeze the eye and optic nerve and lead to visual disturbance and even vision loss.
The shortlist for the Royal Society Insight Investment Science Book Prize 2017 has just been announced. Adam pesters judge Claudia Hammond for the name of the winner (she doesn't tell!) and discusses the criteria for this £25,000 prestigious award. The top 6 books will be featured over the next 6 weeks on BBC Inside Science.
Sexual selection - who you decide to have babies with - is usually decided at the dating stage. But the choice does not have to stop at copulation. Post-mating sexual selection is a thing. Mechanisms such as sperm competition, and cryptic female choice, can happen after sex, but before the sperm fertilises the egg. It's not just an internal thing either, it happens in 'external fertilizers', where eggs are laid, and then fertilized by the male sperm outside the female's body, like come fish do in water. Professor Neil Gemmell, at the University of Otago in Dunedin in New Zealand, has been studying just such processes in Chinook salmon. His findings are surprising and could inform us about human reproduction and fertility.

Thu, 03 Aug 2017 - 867 - Cod fisheries, Our connection to nature, Domestic electricity and Gamma ray bursts
News that the Marine Stewardship Council has reopened the North Sea cod fishery is met by some concern from marine biologist Professor Callum Roberts at the University of York. He says, this may be good news for cod and cod fishermen, but other marine species getting caught up in the drag nets may not be so capable of bouncing back.
In a report out this week, the UK Government announced they are funding £246 million for major changes to the way electricity is produced and stored. New rules will make it easier for people to generate their own power with solar panels, and store it in batteries. But do we have the technology to make it work in a cost effective way? Steven Harris, a consultant in sustainable energy, thinks we'll soon have smart domestic appliances in our homes which better manage the fluctuating supply and demand for power. Expert in energy systems, at the University of Newcastle, Professor Phil Taylor, is researching the next generation of smart appliances and domestic storage batteries.
A new study reports that 69% of Brits feel they have lost touch with nature. Dr. Rachel Bragg, at the Green Exercise Research Unit at the University of Essex and Care Farming UK, unpicks the anecdotal evidence from the facts and explores why a connection with the natural world is so important, why the connection is being broken and what we need to do about it.
Professor of Extragalactic Astronomy at the University of Bath, Carole Mundell, explains how she and other astronomers captured the most complete picture yet of the most powerful type of explosion in the universe - Gamma Ray Bursts. These short-lived bursts of the most energetic form of light, shine hundreds of times brighter than a supernova and trillions of times brighter than our sun.
Thu, 27 Jul 2017 - 866 - Genetics and privacy, Global plastic, Great Ape Dictionary, Ocean Discovery X Prize
Should our genomes be private? Professors Tim Hubbard and Nils Hoppe join Adam Rutherford to discuss concerns about data security and privacy of our genetic data. Once our DNA has been extracted, sequenced and stored as a digital file, what is done with it, who gets to see it and what say do we have in all this?
Back in the 1950's at the dawn of the new plastic age, its everlasting properties were a major selling point. Now, we're dealing with escalating plastic pollution and bulging landfill. But how much plastic are we dealing with? Dr. Roland Geyer has calculated the production, use and fate of all plastics ever made.
Chimpanzees are very communicative animals: they tend to use gestures foremost with vocalisation just to emphasise the flick of a wrist or a stretch of the hand. In an attempt to get a grasp on why, and how, we humans made the shift from gesture-led communication to talking, we need to see how well we can decipher our ape relatives. A new online study called the 'Great Ape Dictionary' wants you to have a go.
The bottom of our seas remains a mysterious other world. Yet, adventuring into the deep depths of the ocean is a major challenge, which is probably why only 5% of it has ever been explored - even though it covers more than 70% of our planet. So to start learning more about our own planet, the Shell Ocean Discovery XPRIZE is awarding a total of $7 million to teams that develop autonomous, unmanned vehicles to map and image the bottom of the seas. Dr Jyotika Virmani tells Adam why ocean exploration is so important, and why it tends to take a backseat to adventuring into space.

Thu, 20 Jul 2017 - 865 - Genetic testing; Pugs on treadmills; Frankenstein
What can genome science do for you? Chief Medical officer Dame Sally Davies recently published her annual report, issuing a plea for a revolution in the use of genetic information in the NHS. She wants DNA tests to be as routine as biopsies or blood tests. Adam chats to geneticist Ewan Birney, head of the European Bioinformatics Institute in Hinxton, about the potential uses and limitations of genetic testing.
Pugs are set to become Britain's most popular breed in the next couple of years. Together with similar dogs, like bulldogs and Frenchies, they are classed 'brachycephalic', having short snouts and compact skulls which makes them susceptible to a breathing problems. Veterinary surgeon Jane Ladlow has studied 1,000 dogs to improve their health today and in future generations. Reporter Graihagh Jackson went to visit the team at Cambridge Veterinary School.
To mark the forthcoming 200th anniversary of the publication of Frankenstein, a new edition has been created especially for scientists and engineers. Adam talks to editor David Guston, from Arizona State University about the lessons this cautionary tale contains for science today.

Thu, 13 Jul 2017 - 864 - Neonics dispute, Hygenic bees, Hip-hop MRI
The results of the first large-scale field study looking at neonicotinoid pesticides and their impact on bees has caused controversy. It was carried out by the Centre for Ecology and Hydrology (CEH) and commissioned and funded by the agricultural chemical companies Syngenta and Bayer. However, both companies have expressed dissatisfaction with the paper. Adam Rutherford talks to Dr Peter Campbell from Syngenta and Dr Ben Woodcock from CEH about the results.
In a separate project, beekeepers have been trying to improve hive health by breeding 'hygienic bees'. These nifty insects love to keep their homes clean and free from disease, improving colony numbers and reducing the need to use antibiotics. Reporter Rory Galloway embarks on some fieldwork at the University of Sussex, with Luciano Scandin, Honeybee Research Facility Manager and Francis Ratnieks, Professor of Apiculture.

Thu, 06 Jul 2017 - 863 - Sex bias in biology, Engineering prize, Olympic bats, Angry Chef
Teams from all over the world have been looking at the differences between male and female mice. They've assessed hundreds of characteristics, from weight changes to cholesterol to blood chemistry. The surprising results show huge differences between the sexes, which have great repercussions for drug development which mostly uses male mice, and humans, for testing. Medicines may be less effective in females, or have greater side-effects, due to the extent of genetic differences being found between the sexes. Adam talks to one of the authors, Prof Judith Mank from University College London.
Three global engineering technologies are in the running for this year's coveted MacRobert Award, the UK's top innovation prize. Adam Rutherford talks to judge Dr Dame Sue Ion to find out more about each of the finalists - Darktrace, Raspberry Pi and Vision RT.
Urban bats are getting smart - sensors newly installed at the Queen Elizabeth Olympic Park in Stratford are using machine learning algorithms to recognise and record the different colonies that emerge after dark. One in five mammal species are bats, and they are often used as an indicator to measure the health of our environment. BBC Science reporter Helen Briggs talks to Prof Kate Jones and the team involved in creating and installing these hi-tech bat phones.
Anthony Warner is a chef. And he's angry. With a background in biochemistry he's pledged to fight fad diets, bogus nutritional advice and celebrity food nonsense wherever he finds it. From Clean Eating to the Paleo Diet, he busts some diet myths for us, and explains why we've unfairly demonised ingredients like gluten.

Modeling the brain with maths. new research using multidimensional models is helping researchers understand the levels of complexity in brain function.
Sexism in science, its as old as...science. We look at how sex bias has influenced the outcome of scientific research throughout history. And also look at how science itself is changing as opportunities for women to pursue scientific careers increase.
And a unique study which turns recordings from police body cameras into empirical data that can be used to assess and improve police interactions with the public.
Thu, 15 Jun 2017 - 860 - Early Humans Were Even Earlier Than We Thought
Early human fossils from Morocco suggest our ancestors walked the earth much earlier than previously thought. Human ancestral fossils from the area were first discovered in the 1960's, but now a re-examination of these and more recent finds suggests they are from an early form of us - Homo sapiens - living in the area around 300,000 years ago.
We have news of a one in a million stellar observation: light bending around a distant star. This is the first time the phenomenon has been observed outside our solar system, and is further proof of Einstein's theory of General Relativity. It involved measurements millions of miles away and many times smaller than the width of a human hair.
Gold mining is a highly polluting process involving toxic chemicals. Marnie Chesterton visits a Scottish gold mine and looks at attempts to make the extraction of gold more environmentally friendly by replacing the toxic chemicals with ingredients more commonly found in vitamins and natural fertilisers.
And US President Trump has announced his intention to pullout of the Paris climate agreement. We look at the implications of the decision for global emissions reduction.
Thu, 08 Jun 2017 - 859 - The Importance of Basic Research
Adam Rutherford discusses the relationship between basic and applied scientific research with guests at the Hay Festival.
Adam is joined by the Astronomer Royal, Lord Martin Rees, physicist Professor Robbert Dijkgraaf, the director of the Institute for Advanced Studies at Princeton University and author of a new essay introducing On the Usefulness of Useless Knowledge, behavioural psychologist Professor Theresa Marteau of Cambridge University and geneticist and writer Professor Steve Jones of University College London.
Thu, 01 Jun 2017 - 858 - Sherpas - dolphin rescue - quantum computing - hot lavas
The superior performance of Sherpa guides on Mountain Everest is legendary. New findings reveal how their bodies make the most of low oxygen levels at high altitude.
Presenter Gareth Mitchell also talks to the Mexican biologist heading a last ditch attempt to save the world's most endangered marine mammal - a small porpoise called vaquita. There are fewer than 30 animals left, all of them in the Gulf of California. The plan is to capture up to half of them and move them to a safe haven in the Gulf, away from the illegal fishing nets that have been trapping and drowning them. Key players in the plan are US Navy dolphins, trained to find and follow the vaquitas so the scientists can catch and move them. The idea is to keep the porpoises in a protected bay until the illegal fishing threat has been tackled.
Also in the programme, white hot lavas and reporter Roland Pease asks whether quantum computing is finally coming of age.
Thu, 25 May 2017 - 857 - Childhood cancers - Ghana telescope - Nano-listening device for cells - Ancient whales
Adam Rutherford goes the pathology archive of Great Ormond Street Hospital in London to hear how tumour samples from child patients about one hundred years ago may improve the diagnosis and treatment of very rare cancers in children today. He meets cancer geneticist Sam Behjati of the Wellcome Trust Sanger Institute and Great Ormond Street pathologist Neil Sebire in the hospital's basement archive.
Africa now has its first radio telescope outside South Africa. It is located in Ghana near the capital Accra. The telescope is in fact a defunct telecoms satellite dish which was spotted on Google Earth images and then re-purposed for cutting edge astrophysics. It is hoped the dish will be the founding instrument of a pan African network of radio telescopes scrutinising exotic celestial objects in the skies above the continent. South African science journalist Sarah Wilds tells the story of how the Ghanaian dish was found and converted.
Nano-engineers in California have created a device 100 times thinner than a human hair which they have used to measure the turbulence created by swimming microbes and record the sounds of heart cells contracting. Don Sirbuly is the professor of nano-engineering at the University of California San Diego who led the team.
A spectacular new whale fossil unearthed Peru is the oldest known member of the evolutionary branch which gave rise to the giant filter-feeding baleen whales of today. The 36 million year old fossil provides evidence for how ancestral whales transitioned from capturing prey with their teeth to filter-feeding with baleen fibres. They may gone through a period of sucking prey from the sea bed.
Thu, 18 May 2017 - 856 - Violins - Social networks and cliques in great tits and snow monkeys - Exploring DNA and art
Classical music fans will know well the legendary violins made by the likes of Stradivarius and Guarneri in the 17th and 18th century. But new acoustical research has found that concert goers rated the music of new fiddles higher than that from old and revered Italian violins. Dr Claudia Fritz of the Pierre and Marie Curie University in Paris explains how she did this study and what she found. Virtuoso soloist Tasmin Little plays her 260 year old Italian instrument for presenter Adam Rutherford and offers her thoughts on the findings.
Adam also hears about personality and social cliques in great tits in Oxfordshire, and social networks and disease in Japanese snow monkeys. Adam chats with Leicester University geneticist Turi King and artists Ruth Singer and Gillian McFarland about their collaborative project to explore DNA through art.
Thu, 11 May 2017 - 855 - The moral brain, stem cell developments, ancient DNA in cave dirt, mangrove forest
Adam Rutherford talks to neuroscientist Molly Crockett about moral decision-making in the brain. She combined brain scanning with a test involving money and electric shocks.
Geoff Marsh reports from Japan where stem cell research appears to be bringing regenerative medicine for a common cause of blindness ever closer.
A team at the Max Planck Institute for Evolutionary Anthropology has pulled off another triumph in the study of ancient human DNA. Viviane Slon explains how they've extracted DNA of extinct species of humans from the soil in caves across Europe and Russia. Adam discusses the significance with Ian Barnes, ancient DNA specialist at the Natural History Museum in London.
Dan Friess of the National University of Singapore studies mangrove forests around the coasts of tropical Pacific and Indian ocean countries. This kind of forest has turned out to store much more carbon than even rainforests, as measured by the hectare. Dr Friess talks about carbon counting in mangroves and how this research may save the forests from further destruction.
Thu, 04 May 2017 - 854 - Homo naledi, First humans in America, Dark matter detector, New theory of dark matter
Controversy has followed the remains of a new species of human, Homo naledi, since it was described in 2015. Buried deep in a South African cave, its primitive features led scientists to believe it was up to three million years old. This week it's been revealed that this estimate was wrong. New dating evidence suggests the skeletons are only 200 000 to 300 000 years old and that means they may have lived alongside other homo species.
Previously, humans were thought to have travelled to America via a land bridge between eastern Siberia and modern day Alaska, somewhere between 17 000 - 40 000 years ago when sea levels were lower than they are today. Researchers from the San Diego Natural History Museum now present evidence that suggests this transition could have been much earlier - nearly 100 000 years earlier. Adam talked to Chris Stringer, researcher in human evolution at the Natural History Museum in London, to unpick the evidence.
Dark matter is a mystery that has evaded scientists for decades. Now the biggest and most sensitive detector is being built in South Dakota and scientists believe the Lux-Zeppelin experiment will soon be able to detect one of the candidates for dark matter, the elusive particle known as a weakly interacting massive particle (WIMP). Graihagh Jackson got a sneak peak of the key components, including the 'eyes' of the detector, before they're sent off for installation.
Adam Rutherford talks to cosmologist Carlos Frenk from the University of Durham and learns of an alternative theory to describe this mysterious dark matter - a whole new dark sector. This sector contains a vast range of different dark particles, from photons to bosons, that could interact with normal particles.
Thu, 27 Apr 2017 - 853 - Cassini’s death, scrapping diesel, weather balloon, satellites monitoring volcanos
The Cassini-Huygens mission has been monumental for science. For thirteen years the probe has gathered data on Saturn, revealing more about the gas giant than we have ever known before. But now, Cassini is running out of fuel. Adam Rutherford talks to Professor Michele Dougherty of Imperial College about the plans for Cassini's spectacular end, which will be to burn up in Saturn's atmosphere later this year. The descent begins this week and Cassini will collect exciting new data until the end.
Next week, Theresa May will unveil her plans to kerb air pollution and it is believed that some diesel drivers could be paid up to £2,000 to trade in their vehicles. Diesel cars emit nitrogen oxides - a pollutant that has been linked to nearly 12,000 UK deaths in 2013. This is the second highest in Europe after Italy. However, this isn't the first scrappage scheme to be brought in. Philippa Oldham from the Institution of Mechanical Engineers and Adam discuss the merits and pitfalls of an initiative like this.
Thousands of balloons are launched every day to measure temperature, pressure and humidity of the air. Kerri Nicoll from the University of Reading wants to add cheap, volcanic ash sensors to these balloons which are going up anyway. This could vastly improve the limited information we currently have on volcanic eruptions, allowing us to quickly see rises in ash particles and therefore improve ash cloud forecasting.
Many of the world's volcanoes aren't monitored but a new technology from the University of Leeds should mean that scientists can keep track of all 1,500 them by the end of the year. The technology involves monitoring changes in ground deformation from satellites in space, which will give clues as to whether a volcano is about to erupt. For those living near unmonitored volcanoes, this could provide an early warning system and save their lives.
Thu, 20 Apr 2017 - 852 - 23andMe Genetic Sequencing, Human Knockout genes, Coral Bleaching
23andMe is one of the biggest providers of home genetic testing kits and if you live in the UK, it's the only one that also includes various genetic analyses relevant not just to ancestry, but also to health. After a previous ban, the Food and Drug Administration for the first time approved marketing of the 23andMe Genetic Health Risk tests for diseases in the US. Adam Rutherford talks to geneticist Professor Matthew Cobb of the University of Manchester and to medical ethicist Dr Sarah Chan of the University of Edinburgh about how useful this genetic information can be and about who owns the data.
New research published this week has revealed something really quite bizarre about our own genomes: that we can survive normally with a considerable number of dysfunctional genes. We've got around 20,000 genes, and you might think that you need them all, as when they don't work, they could lead to a serious health condition. But from a study of more than 10,000 people from Pakistan more than 1300 mutations were found to have no effect on their health. Geneticist Robert Plenge explains the research.
The Great Barrier Reef has taken another huge hit with a mass bleaching event occurring a second year in a row. Over two thirds of the reef is now seriously damaged. Professor Jorg Wiedenmann of the University of Southampton explains that if bleaching events continue to happen at this rate, the world's largest coral reef will never recover.
Thu, 13 Apr 2017 - 851 - Creation of island Britain, Sleep gene, Mary Kelly forensics, Global Tree Search survey
Adam Rutherford examines a new study published this week which reveals how a megaflood and giant waterfalls severed our connection to what is now France, resulting in the creation of island Britain and the watery moat of the English Channel. Jenny Collier of Imperial College London uncovers the ancient evidence dating back 450 000 years ago.
The dream of unbroken sleep is a complex interaction between our environment and our genes, and new research is a step towards understanding the genetics of sleeping patterns. Jason Gerstner of Washington State University discusses his isolation of a gene that seems to play a crucial role in sleep across a number of species including humans.
Turi King played a pivotal role in the identification of Richard III from bones discovered in a Leicester car park She's now involved in another infamous cold case - that of Jack the Ripper. Her interest is in the last of his five canonical victims, known as Mary Kelly, and she's authored a commissioned report on the possibility of identifying the body of Mary Kelly using DNA.
And Paul Smith from Gardens Conservation International discusses the new Global Tree Survey - the biggest and the most comprehensive database of all the trees in the world - accumulated from 500 papers, and nearly four centuries of dendrology.
Producer Adrian Washbourne.
Thu, 06 Apr 2017 - 850 - Climate change and extreme weather; Primate brain size; Earthquake forecasting; Planet 9
Following yesterday's US House Committee on Science,Space,and Technology's controversial hearing on scientific method and climate change, Adam Rutherford meets atmospheric scientist Professor Michael Mann after he emerged from the heated debate and who's just published a new paper suggesting a direct link between extreme weather and greenhouse gases via a particular behaviour of the jet stream across the northern hemisphere
How has intelligence evolved? For over 2 decades the idea has prevailed that primate brain size and intelligence has been driven mainly by complex social hierarchies. But a new study by Alex DeCascien of New York University suggests that diet is a better predictor of brain size.
This month is the 6th anniversary of the earthquake and tsunami that devastated much of Japan's coastline. Roland Pease reports on new research that aims to embrace uncertainty to improve quake forecasting
And we hear how you can join in the search for the missing mysterious 9th planet of our solar system. Adam Rutherford hears from astronomer Brad Tucker on Walkabout at the Mount Stromlo Observatory in New South Wales
Producer: Adrian Washbourne.
Thu, 30 Mar 2017 - 849 - Comet 67P images; Etna eruption; Brain navigation; Octopus intelligence
The recent Rosetta mission to image and land a probe on a comet was an astounding achievement. Rosetta took thousands of photos mapping the entire surface of comet 67P/Churyumov-Gerasimenko , as it dramatically changed over 2 years. This week analysis of 18000 67P pictures are out of the shade and into the sunlight. Adam Rutherford talks to study leader Raamy El Maary on the intriguing insights and what they suggests about the evolution of comets as they pass through our solar system.
And while no-one has any doubt that volcanoes are extremely dangerous forces of nature, Science correspondent Rebecca Morelle was caught in an unusual and terrifying eruption last week. She tells BBC Inside Science the perils of reporting up close from the side of Etna and the rare kind of eruptions that are unique to snowy volcanoes.
What are our brains doing when we're navigating through towns and cities? A new study from a team at University College London has made detailed maps of brain activity when negotiating the very windy London streets of Soho and compared it to what our brains are up to when we're simply following a sat nav. Hugo Spiers discusses the results and how this kind of neuroscience has a role to play in the future design of new street networks and cities.
And we feature the private life of the octopus - a seemingly alien intelligence right here on Earth as philosopher Peter Godfrey-Smith discusses his new book "Other Minds: The Octopus and the Evolution of Intelligent Life", in which he literally dives into the oceans and delves in to the workings of the octopus mind

Thu, 23 Mar 2017 - 848 - Boaty McBoatface in Antarctica, Aeroplane biofuels, Bakhshali manuscript, Goldilocks zones
The submarine famously named Boaty McBoatface is deployed this week for its first mission to examine a narrow submarine gap in the South Atlantic. Mike Meredith of the British Antarctic Survey tells Adam Rutherford how this research into the behaviour of deep water at this crucial point in the oceans will help us answer key questions about global ocean temperature flows.
Some close-quarter flying in the wake of a jet has provided new insights on reducing aircraft pollution. Richard Moore at NASA Langley in Virginia describes how he's taken to the skies to measure gasses emitted by new biofuels to assess their impact in reducing carbon soot particles, aircraft contrails and climate-changing cloud formations across the sky
Angela Saini visits the Bodleian Library in Oxford where the Bakhshali manuscript which contains possibly the very first graphical representation of the number zero is finally being carbon dated so we can better understand its scientific importance
And the habitable zones around stars in our the universe just got a whole lot bigger. Lisa Kaltenegger of the Carl Sagan Institute reveals how the presence of volcanoes pumping out hydrogen has a significant warming effect on planets, and increases the range of the so called Goldilocks Zone
Producer: Adrian Washbourne.
Thu, 16 Mar 2017 - 847 - Rise of the Robots: 3. Where is my mind?
From Skynet and the Terminator franchise, through Wargames and Ava in Ex Machina, artificial intelligences pervade our cinematic experiences. But AIs are already in the real world, answering our questions on our phones and making diagnoses about our health. Adam Rutherford asks if we are ready for AI, when fiction becomes reality, and we create thinking machines.

- 845 - Rise of the Robots: 2. More human than humanMon, 06 Mar 2017
- 844 - Rise of the Robots: 1. The history of things to come
The idea of robots goes back to the Ancient Greeks. In myths Hephaestus, the god of fire, created robots to assist in his workshop. In the medieval period the wealthy showed off their automata. In France in the 15th century a Duke of Burgundy had his chateau filled with automata that played practical tricks on his guests, such as spraying water at them. By the 18th century craftsmen were making life like performing robots. In 1738 in Paris people queued to see the amazing flute playing automaton, designed and built by Jacques Vaucanson.
With the industrial revolution the idea of automata became intertwined with that of human workers. The word robot first appears in a 1921 play, Rossum's Universal Robots, by Czech author Carel Chapek.
Drawing on examples from fact and fiction, Adam Rutherford explores the role of robots in past societies and discovers they were nearly always made in our image, and inspired both fear and wonder in their audiences. He talks to Dr Elly Truitt of Bryn Mawr College in the US about ancient and medieval robots, to Simon Shaffer, Professor of History of Science at Cambridge University and to Dr Andrew Nahum of the Science Museum about !8th century automata, and to Dr Ben Russell of the Science Museum about robots and workers in the 20th century. And Matthew Sweet provides the cultural context. Show less
Fri, 03 Mar 2017 - 843 - Earth's Earliest Life, The Benefits of Pollution, Sexuality and Science and New ideas on Evolution
The World's oldest sedimentary rocks reveal traces of our earliest ancestors. New analysis shows life forms existed more than 3.7 billion years ago which were very similar to those found in our deepest oceans today, microbial life around hydro thermal vents.
Some pollution might be good for the world oceans. New finding from China show how iron oxide pollution from power generation and industry has been turned into a source of nutrients for phytoplankton - by interacting with other chemical pollutants. The researchers say this is increasing the ability of the ocean to lock up atmospheric carbon dioxide and so reduce the impact of man made greenhouse gasses. They query whether reducing this kind of pollution could have a negative impact.
This week The Royal Society celebrated LGBT history month and 50 years since the partial decriminalisation of homosexuality in England and Wales Rory Galloway meets Sir Dermot Turing, the nephew of renowned computer scientist Alan Turing, to discuss Alan’s Legacy for LGBT scientists today, and we look at the continued impacted of homophobia in science.
And we hear about a new test for ideas in Evolution. This involves recreating the ancestors of fruit flies. The findings have overturned an established theory on genetic inheritance in these alcohol tolerant flies.
Thu, 02 Mar 2017 - 842 - The perils of fake science news, The neanderthal inside us, What The Beatles really sang - statistically speaking
A woolly story about resurrecting mammoths raises serious questions for medical ethics. News of a scientist's plan to resurrect mammoths has spread around the world. However the story is largely untrue. We look at how this kind of 'fake science news' story can impact on perceptions of real medical research - some times with negative consequences.
Almost all Europeans and Asians carry Neanderthal genes. Until recently these were thought to have little impact on us today, but new research shows they may be involved with determining height and aspects of both our physical and mental health.
And what were Lennon and McCartney really thinking when they wrote their hit songs? Thanks to the number crunching power of computer algorithms the emotional content of 23 years worth of their compositions have been analysed. The results are both startling and for Beatles fans perhaps a little unsurprising.
Thu, 23 Feb 2017 - 841 - Science and cyber security, Dinosaur babies, Winston Churchill and level crossings
Testing cyber security with science. The UK now has a new National Cyber Security Centre. However there is very little scientific evidence against which to test the detection of cyber attacks and effectiveness of measures to prevent them. We ask what is needed to turn cyber security into a more scientific discipline.
Winston Churchill and Aliens. Throughout his life Churchill maintained a strong interest in scientific developments and wrote widely on subjects from quantum mechanics to nuclear energy. Newly discovered papers show he also had an interest in the potential for life on other planets.
Dinosaurs and egg laying. A new fossil find revealing a dinosaur with an unborn baby suggests live births may have occurred many years earlier than previously thought.
Turn off at level crossings. New research suggests personal messages about the impact of engine fumes on health may be the most effective way of persuading drivers to switch off their engines at level crossings.
Thu, 16 Feb 2017 - 840 - Measuring human impact on earth, Awards for engineers, Sounds of space junk.
Quantifying the impact of humanity on the earth's natural systems. Why human activity now has a larger effect on our planet than the forces of nature. We look at how mathematical equations can now be used to compare historical natural processes with contemporary man made changes. And we ask where current developments will take us in years to come.
The Queen Elizabeth Prize for Engineering has been awarded to the inventors of digital imaging sensors. First invented in the 1970's, many of us use this technology everyday. These sensor can be found inside every digital camera ever made, from the devices used on space probes to collect distant images from the far reaches of the universe to the ubiquitous pocket cameras in our mobile phones.
The earth is surrounded by junk - space junk. Many thousand of pieces of junk orbit the planet, left over from the history of everything we've ever sent into space. A new project has given a voice to this junk, and created a machine which plays simulated sounds of the junk as it passes overhead.

Thu, 09 Feb 2017 - 839 - Wildlife trafficking, New quantum computers, Ancient bird beaks, Glassblowing.
Conservation and conflict. A year long BBC investigation has exposed an illegal animal trafficking network stretching from West Africa to the Middle East and Asia. Traffickers have used fake permits to undermine international conservation efforts.
New developments in Quantum computing. Sussex University are building a new type of modular Quantum computer. We attempt to explain what Quantum computing is.

Thu, 02 Feb 2017 - 838 - Crime, volcanoes, ghosts and how we are influenced by the genes of unrelated others
The genes of unrelated others can influence our health and behaviour. New research suggests the genetic make up of our partners can have a profound influence on our lives. Scientists have quantified genetic influence , in mice at present but the plan is to try to extend this to human interactions. If accepted this has potentially far reaching consequences for studying heritability and also perhaps modern medicine as the findings suggest an illness can in part be influenced by those we live with.
The use of DNA evidence in criminal cases has sometimes been given far more weight than it deserves. In the worst examples there have been miscarriages of justice where DNA evidence has been misinterpreted. The fiction of DNA as a 'magic bullet' pervades TV drama and films - but views of DNA evidence as infallible are also widely held amongst the public, police and lawyers. Forensic specialists explain what we can and can't find from DNA evidence.
Oxford's Bodleian library has manuscripts stretching back to medieval times depicting volcanos discovered in the 6th century. These manuscripts also contain remarkable interpretations of eruptions and associated volcanic events, often mixed with mythology. Although those recording such events did not understand what they were scientifically, some of the depictions and ideas of what was happening are surprisingly accurate. Roland Pease and Professor David Pyle take a look at this remarkable collection.
Nearly a hundred years ago, Oliver Lodge, eminent physicist and the first to demonstrate radio waves, published a book about life after death. It was entitled 'Raymond' after his son who was killed in the First World War. Lodge was a believer in ghosts and telepathy, and conducted experiments to test their existence. Adam Rutherford and Samira Ahmed look at how Oliver Lodge squared his scientific and spiritualist beliefs - and how the latter led to him, as Britain's most well know scientist of his time, being written out of scientific history.
Thu, 26 Jan 2017 - 837 - Antarctic science rescue, Killing cancer with viruses, Measuring wind from space and the Last man on the moon
Why the British Antarctic science base is being temporarily abandoned. New cracks have appeared in the Ice shelf on which the Halley research station sits.
The promise of viro-therapy for treating cancer. Scientists have successfully used a virus to kill cancer cells. They say this could form the basis for a vaccine that could be injected to destroy tumours.
The limitations of mouse models. Many animals are used for testing treatments intended for humans, we explain why the results of such experiments can't always be applied to people.
Measuring wind speeds from space. A new satellite will lead to more accurate weather forecasts.

Thu, 12 Jan 2017 - 835 - RIP Granny the oldest Orca - Graphene + Silly Putty - Moving a Giant Magnet - Space in 2017
The world's oldest known killer whale is presumed dead. At an estimated age of 100 years, 'Granny' was last seen with her family in October. The scientists who've followed her and her pod for four decades announced that they believe she has died somewhere in the North American Pacific. Adam Rutherford talks to evolutionary biologist Darren Croft of the University of Exeter about this remarkable animal and the insights that Granny and her clan have provided on killer whale social life and the evolution of the menopause.
Adam also hears how a 'kitchen' experiment with Silly Putty and the form of carbon known as graphene led to the creation of an ultra-sensitive electro-mechanical sensing material. G-putty may provide the basis for a continuous and wearable blood pressure monitor. It can also detect the footsteps of spiders. Professor Jonathan Coleman of Trinity College, Dublin explains how its properties arise from mixing the two materials.
Reporter Marnie Chesterton tells how a 700 tonne magnet was moved 3,000 miles by road and river across the United States, inciting both conspiracy theories and adulation. Now homed at Fermilab - the US's premier particle physics lab - the magnet is about to start probing the laws of the Universe in the Muon g-2 experiment.
BBC science correspondents Rebecca Morelle and Jonathan Amos pick their space and astronomy highlights for the coming year.

Thu, 05 Jan 2017 - 834 - Listeners' Questions
Adam Rutherford puts listeners' science questions to his team of experts: physicist Helen Czerski, cosmologist Andrew Pontzen and biologist Yan Wong. Queries include gravity on sci-fi space ships, how animals would evolve on the low gravitational field of the Moon, gravitational waves, mimicry in parrots, sea level rise, the accelerating universe, dinosaur intelligence, the Higgs field and concerns about oxygen levels in the atmosphere.
Further questions are answered in the podcast version of the show. They cover Antarctic dinosaurs, reducing CO2 levels in the atmosphere by trapping it as limestone, and Neanderthal DNA.
Thu, 29 Dec 2016 - 833 - Inuits and Denisovans, Sex and woodlice, Peace through particle physics, Caspar the octopus in peril?
Can Inuit people survive the Arctic cold thanks to deep past liaisons with another species? Adam Rutherford talks to geneticist Rasmus Nielsen who says that's part of the answer. His team's research has identified a particular section of the Inuit people's genome which looks as though it originally came from a long extinct population of humans who lived in Siberia 50,000 years ago. The genes concerned are involved in physiological processes advantageous to adapting to the cold. The conclusion is that at some point, the ancestors of Inuits interbred with members of this other species of human (known as the Denisovans) before people arrived in Greenland.
Also in the programme:
The woodlice which are made either female or male because of a gene that once belonged a bacterium. The gene came from a dead microbe and was incorporated by chance into the woodlouse genome. This is the first known instance of the invention of an animal sex chromosome through bacterial donation. We talk to Richard Cordaux of the University of Poitiers and Nick Lane of University College London about the discovery.
Peace through particle physics. Roland Pease visits SESAME in Jordan - the Middle East's first synchrotron facility is about to start operating. The experiment brings together scientists from all over the Middle East in common cause, with for example Israeli, Palestinian, Iranian, Egyptian and Turkish scientists working side by side.
Marine ecologist Autun Purser tells Adam about his European team's discovery of ghostly octopods living at 4,000 metres on the dark, cold sea bed of the Pacific ocean. Autun's camera has caught extraordinary egg brooding behaviour by this new kind of octopus. It lays its eggs half way up the stalks of dead sponges and then guards them for several years until they hatch. Unfortunately, the sponges only grow on lumps of metal-rich rock called manganese nodules which form slowly on the deep sea floor. Several companies are now exploring the possibility of extracting vast quantities of these nodules in deep sea mining, threatening the existence of the sponges and the octopods depending on them.
Thu, 22 Dec 2016 - 832 - Rock traces of life on Mars, Desert fireball network, Gut microbes and Parkinson's Disease, Science Museum's maths exhibition
Could rocks studied by the Mars rover Spirit in Gusev Crater in 2007 contain the hallmarks of ancient life? Geologist Steve Ruff of Arizona State University talks about what he found in hot springs in Chile which begs that question. He says the evidence is intriguing enough for NASA to send its next and more sophisticated Mars robot back to the same spot on the Red Planet in 2020.
Adam also talks to Phil Bland of Curtin University in Australia - one of the creators of the Desert Fireball Network - an array of automated cameras across Australia, built to locate where shooting stars land as meteorites and also pinpoint from where they came in the solar system. Boosting the chances of collecting these meteorites and knowing their space origins should helps us to better understand how the Earth and other planets formed 4.5 billion years ago.
There's new compelling evidence that microbes in the gut play a role in the development of Parkinson's disease. Tim Sampson of Caltech in the US outlines his experiments which raise this possibility and Patrick Lewis, another Parkinson's researcher at the University of Reading, puts the new findings into a wider context.
Adam takes a tour of the spectacular new mathematics gallery at the Science Museum in London. The Winton Gallery's exhibited objects and design by the celebrated architect Zaha Hadid focusses on mathematics in the real world. Adam's guide is lead curator David Rooney.
Thu, 08 Dec 2016 - 831 - Alzheimers research, Lucy in the Scanner, Smart bandages, From supernovae to Hollywood
Alzheimers disease is now the leading cause of death in the UK, but there are as yet no treatments to halt or reverse it. There was huge disappointment last week when the drug company Eli Lilly announced that a large, phase 3 clinical trial had failed to show any benefit to mild dementia sufferers from its antibody therapy, solanezumab. So where does this leave our basic understanding of biology of Alzheimers disease and how we might most effectively treat or cure it? Adam Rutherford talks to Alzheimers researcher Tara Spires-Jones of the University of Edinburgh.
Also in the programme: The skeleton of the world's most famous fossil, Lucy, has received a body scan which revealed she spent a considerable portion of her life climbing trees. Researchers at the University of Bath are making smart bandages for burns patients which glow when their wounds become infected. Adam also talks to the astrophysicist who gave up studying exploding stars to apply his maths to Hollywood stars in the movie business.
Thu, 01 Dec 2016 - 830 - Predator bacteria therapy, New money for UK science, Stick-on stethoscope, Taming fears in the brain scanner
Bdellovibrio is a small bacterium which preys and kills other bacteria. A team of researchers in the UK has shown in animal experiments that injections of the predator microbe can successfully treat infections. So how close does this take us to Bdellovibrio therapy for human patients and what part might it play in tackling the growing crisis of antibiotic resistance? Adam Rutherford talks to Professor Liz Sockett of the University of Nottingham.
The British government has announced that it will be spending an additional £2 billion on research and development by 2020. Commentators say it is the largest hike in public funding for science in a very long time. Dr Sarah Main of the Campaign for Science and Engineering, and Dr Arnab Basu, physicist and CEO of Kromek, discuss the new money and how it would be best used.
Also in the programme, materials and electronics engineers in the US have devised a small wearable heart monitor - the size and thickness of a sticking plaster. Adam talks to its lead designer Professor John Rogers of Northwestern University in Chicago. And could phobias be cured without exposure to the thing which frightens people? Dr Ben Seymour outlines an intriguing experiment which involved reading people's thoughts in a brain scanner, which suggests ultimately it may be possible.
Thu, 24 Nov 2016 - 829 - Does Pluto have an ocean, Antarctica's oldest ice, Meat emissions, Swifts fly ten months non-stop
Does the distant dwarf planet Pluto have an ocean beneath its thick crust of ice? It's certainly possible, according to a group of researchers who are analysing the data from the New Horizons Pluto flyby last year. They argue that a deep ocean of water would best explain the position of the great heart shaped depression on Pluto's surface. Adam Rutherford quizzes planetary scientist Francis Nimmo about this new hypothesis.
Adam also talks to glaciologist Robert Mulvaney of the British Antarctic Survey, who is now setting off for the frozen south to prospect for the oldest ice in Antarctica. He's part of a European project which aims to drill deep into the ice sheet of East Antarctica and chart the climate and atmosphere history of Antarctica back to 1.5 million years ago.
Are grass-fed cattle better for the global climate than cattle fed on grain-based feeds? Dr Tara Garnett of the Food Climate Research Network at Oxford University responds to listeners comments on carbon emissions and diet.
Swifts can fly for 10 months non-stop, never touching the ground. Anders Hedenstrom of Lund University discovered this remarkable fact by fitting birds with a tiny electronic backpack which recorded their location and flight activity across a whole year.
Thu, 17 Nov 2016 - 828 - Climate change questions, Animal computer interaction, Sounds and meaning across world's languages
Climate change is in the news this week. The international Paris agreement to curb global temperature rise has just come into effect but President Elect Donald Trump has said he would take the United States out of the process. In BBC Inside Science, Adam Rutherford puts listener's questions and views about climate change to experts, such as the emissions reduction impact of becoming a vegan to a proposed technology to remove carbon dioxide from the planet's atmosphere. Myles Allen and Peter Scarborough of the University of Oxford, and Anna Harper of the University of Exeter are consulted.
The programme also visits a lab at the Open University which studies the way animals interact with computer technology. Research includes technology to enable dogs to phone the emergency services if humans get into trouble, and using dogs to detect cancer. Reporter Marnie Chesterton meets researcher Clara Mancini and dogs Ozzie and Tory.
Are there commonalities across the world's languages between the sounds in particular words and the meanings of those words? The traditional thinking in linguistics says no. But new research surveying the meaning and sounds of words across 6,000 languages from the Americas, Asia, Europe and Australasia finds otherwise. The 'r' sound is used in words for the colour 'red' all around the world at frequencies much higher than by chance. The case is the same for the words for 'nose' and other parts of the body. Morten Christiansen of Cornell University talks to Adam Rutherford about the research.
Thu, 10 Nov 2016 - 827 - Italy's quakes, Ebola virus, Accidental rocket fuel, China in space
In the past three months, central Italy has been shaken by several large earthquakes. The quake near Norcia on 30th October was the most powerful for decades. In late August, another struck near Amatrice, causing 300 lost lives. Adam Rutherford talks to seismologist Ross Stein about why this part of the Italian peninsula is so prone to shaking, whether there is a pattern in the recent activity and whether the scientists are getting any better at earthquake forecasting.
The recent Ebola epidemic in West Africa was the largest and most deadly of its kind so far. More than 11,000 people were killed by the virus. Now two groups of virologists have discovered that early in the epidemic's course, the Ebola virus underwent a genetic change which allowed it to infect human cells more easily. Could this mutation explain the terrible scale of the outbreak of 2013 to 2016?
Also in the show, the chemists who are aiming to make ammonia fertiliser production more environmentally friendly but made rocket fuel instead; and the past and future of the Chinese space programme.
Thu, 03 Nov 2016 - 826 - Making mozzies safe with a microbe, CO2 at 400 ppm, Chixculub crater rocks, Why Mars Lander failed
Adam Rutherford meets the Australian scientist behind a radical new technique to prevent mosquitoes from spreading the zika and dengue fever viruses to people. The method involves infecting mosquitoes with a harmless bacterium. The microbe doesn't kill the mosquitoes but stops the viruses multiplying inside them and spreads rapidly through wild mosquito populations. After 15 years of research, the mosquito control method is about to be deployed in large scale trials in urban areas in South America.
Also in the programme, the world's atmosphere crosses an iconic threshold as measured by the concentration of the greenhouse gas carbon dioxide: scientists get their hands on the rocks at the centre of the extinction of the dinosaurs: and details emerge of why the European Space Agency's recent Mars lander crashed onto the Red Planet.
Thu, 27 Oct 2016 - 825 - HFC Ban; Human Cell Atlas; Origin of Hunting with Dogs
Biologists are to begin a 10 year international project to map the multitude of different kinds of cell in the human body. The average adult is built of 37 trillion cells and if you look in a text book, it will say there are about 200 distinct varieties of cells. But this is a grand underestimate. There could in fact be 10,000. The Human Cell Atlas project aims to identify every type and subtype of cell in every tissue of the body - a massive endeavour which, the cell mappers argue, will have profound benefits for medicine.
Adam Rutherford also talks to zoological archaeologist Angela Perri whose research is aimed at discovering when our ancestors first started to use dogs as 'hunting' technology. Her work involves joining hunts with dogs in the modern day as well as traditional archaeological field work.
He also explores the science behind exploding smart phone batteries and the new international climate agreement to rid the world of hydrofluorocarbons.
Thu, 20 Oct 2016 - 824 - Life on Mars? Quantum Gravity. The deep origins of bird song
Mars is about to be visited by the first space mission for 40 years which is designed to seek signs of life on the Red Planet. Adam Rutherford talks to Dr Manish Patel of the Open University, a senior scientist on the European Space Agency's ExoMars Trace Gas Orbiter. Once the spacecraft starts work, it may solve the mystery of ebbs and flows of methane gas in the Martian atmosphere. It may answer whether the gas is being produced by life beneath the planet's cold dusty surface.
The American space agency Nasa already has a mission well underway on the Martian surface.. For four years, Curiosity has been exploring the deep geological past of a huge Martian crater and mountain. Recently possible signs of liquid water have been seen nearby. But rather than going closer to study it, Nasa wants the rover to avoid it. Project scientist Ashwin Vasavada explains why.
Carlo Rovelli is a theoretical physicist and writer. His latest book 'Reality is not what it Seems' explores the history of thought about the physical nature of the universe and one of the latest incarnations of that great quests - loop quantum gravity theory. He talks to Adam about the fine grain of space and time, and exploding black holes.
Palaeontologist Julia Clarke has discovered the oldest fossil of a bird's organ of song, the syrinx. At the University of Texas, Austin the delicate structure turned up in an X ray scan of a 66 million year old bird fossil from Antarctica. The fossil syrinx is so well preserved, it is possible to say what the call of this ancient bird Vegavis would have sounded like. It's also a massive boost in the quest to discover when birds first sang and recreating the dawn chorus back in the Age of Dinosaurs.
Thu, 13 Oct 2016 - 823 - Microbead impact, Remote animal logging, Royal Society book prize, Surgewatch
The government has announced that tiny pieces of plastic in personal beauty products that end up in the oceans will be banned from sale in the UK. But given their size how much of a problem are minuscule bits of plastic to marine life? Gareth Mitchell meets Professor Richard Thompson of Plymouth University to uncover the marine biology concerns that have led to the micro bead ban.
However much we watch animals in the wild we can't really know what they get up to. Rory Wilson, Professor of Zoology at Swansea University, has found a way to eavesdrop on animals that live in remote parts of the world and he's revealed some of his latest discoveries at the British Science Festival in Swansea today. He's developed a logging device that collects a whopping amount of data - 400 items each second. His daily diary collects amongst other measurements, location, magnetic field, temperature, and pressure. Before his talk, Adam Rutherford went along to Rory Wilson's lab and found out which animals he's attached the logger to and discovered their secret life.
In the final entry of this year's shortlist for the Royal Society book prize Jo Marchant discusses Cure - which examines how the mind plays a crucial role in health. Our thoughts, emotions and beliefs, it seems, can ease pain, heal wounds, fend off infection and heart disease and even slow the progression of AIDS and some cancers. So what is the potential of the mind to heal - and what are its limits?
As many as 530 key infrastructure sites across England are still vulnerable to flooding, according to a government review out today. Southampton University researchers want to understand better how floods happen and how to predict them. Beyond burst river banks and breached defences, they're building up a more detailed picture, house by house, and street by street of what happens when water levels rise. For that they need data, lots of it going back as far as possible. Ivan Haigh at the National Oceanography Centre and his colleagues are pulling all kinds of photos and records together in an interactive multi-purpose online shared database called Surgewatch.

Thu, 08 Sep 2016 - 822 - Proxima b exoplanet, The Hunt for Vulcan, East Antarctic lakes, Deep sea shark hunting
The nearest habitable world beyond our Solar System might be right on our doorstep . Scientists say their investigations of our closest star, Proxima Centauri, show it to have an Earth-sized planet orbiting about it. What's more, it is moving in a zone that would make liquid water on its surface a possibility. Gareth Mitchell hears from Guillem Anglada-Escudé whose "Pale Red Dot" team made the discovery and discusses what the "earth- like" claims actually mean.
The planet hunters of today search for worlds beyond our Solar System. The planet hunters of a century or so ago, were still going crazy trying to find one more planet orbiting this sun. In The Hunt for Vulcan shortlisted for this year's Royal Society Book Prize, Prof.Thomas Levenson examines the craze known as Vulcan -mania, in the desperate search for another planet in an attempt to explain the odd orbit of the planet Mercury. But why did the phantom planet theory survive for so long?
We examine observations from space of fleeting blue lakes in East Antarctica. They come and go with the seasons, forming during the warmer months of the south pole summer. As Amber Leeson of Lancaster University explains, many of the lakes then drain away, an effect already been found in Greenland but never, until now, in this part of the Antarctic. And their effect is cause for concern.
Deep sea sharks are nearly impossible to track around the planet, however they inherit the chemistry of the things they eat. Researchers at Southampton University have worked backwards and by examining the chemistry of the sharks, they've been able to determine what things a shark has been eating but also where in the world it has been feeding. Chris Bird and Clive Trueman discuss how they're building up the first accurate pattern of their extraordinary movements.

Thu, 25 Aug 2016 - 821 - Autonomous cars, Bees and neonicotinoids, Marden Henge, Royal Society Book Prize
Ford has just announced that by 2021 it's going to have a driverless car on the road with no steering wheel. It sounds ambitious, since it is the intermediate stop on the road to full autonomy that's raising some of the big research questions at the moment. How can drivers enjoy the reduced workload of automation whilst still being alert enough to take control if something goes wrong? For a drive of the future, Gareth Mitchell went to Southampton University's simulator facility for automated vehicles to meet Professor of Human Factors in Transport, Neville Stanton.
Neonicotinoid pesticides have been used widely in protecting the UK's vast acreage of oil seed rape. Research out this week claims there is a link between 'neonics' as they're known, and waning numbers of bees - with the worst affected populations declining by a third. The study has grabbed the headlines because of its scope - 18 years' worth of observations in the countryside. But how much is the link a cause for concern? Researchers Ben Woodcock and Nick Isaac of the Centre for Ecology and Hydrology discuss the results.
Nestled in the Vale of Pewsey, Marden Henge is an artificial mound considered by archaeologists to be one of the best of the area's neolithic monuments. It represents the missing link between the stone circles at Stone Henge and Avebury. Teams from Reading, Historic England, and other volunteers, have been digging there this summer. Roland Pease has been along to meet them.
And we've the next nomination in this year's Royal Society Science Book prize shortlist: Tim Birkhead's new book, The Most Perfect Thing, all about bird eggs. It covers how they are made, why they are the shape they are, where their patterns come from and much more.

Thu, 18 Aug 2016 - 820 - Blow to the LHC "bump", Crow intelligence, Robot mudskippers, Royal Society book prize
New results have squashed the hope that the hints of a new particle detected by the Large Hadron Collider would confirm the existence of something extremely exotic, such as a new Higgs, or even the theoretical Graviton. Instead, the intriguing data 'bump' turns out to be nothing more than a statistical fluctuation. Physicist Jonathan Butterworth of UCL discusses whether this false alarm affects the LHC's chances of finding something else.
Crows, ravens and other members of the bird family we call Corvids are well known to have sophisticated skills in tool use and problem solving. Research out this week reports ravens bending wire to help forage for their food. But what constitutes intelligence in bird brains? Adam Rutherford visits the Tower of London where ravens have been permanent residents since the 16th Century, and so quite a good spot for scientists to go and put bird brains to the test. He meets Sophie Hamnett and Nathan Emery from Queen Mary, University of London.
Animals evolved in the seas, but by about 400 million years ago, some fishy creatures had evolved to begin walking on terra firma. Nowadays we look at creatures like mudskippers, that can swim and wade, to see how those first crawlers might have crept up the beach. A new study has gone one step further: Jonathan Webb went to Georgia Tech in Atlanta to meet the robot mudskippers.
We're profiling each of the shortlisted books for the Royal Society book prize this year, and this week it is the turn of oncologist Siddartha Muhkerjee. He has turned his attention to trying to understand the root of all cancers, and the mental health issues his own family endure. His new book, The Gene, details the central concept in inheritance.
Producer Adrian Washbourne.
Thu, 11 Aug 2016 - 819 - Signs of life on planets, Royal Society Book Prize, Queen Bee control, Galactic Prom 29
What should we be looking for when searching for life on other planets beyond our solar system? Scientists urgently need to come to a consensus on this as a new suite of telescopes soon begins detecting. The space agency NASA has put together a virtual institute called The Nexus for Exoplanet System Science, and they've just met to work out how we should be looking for bio signatures - on the burgeoning catalogue of worlds beyond the Solar System. Adam Rutherford hears from Sarah Rugheimer, an astrobiologist from the University of St Andrews, on why the world's astrobiologists have decided to lay down the law.
The Royal Society Insight Investment Book Prize celebrates some of the best science published each year. Today the judges announced their shortlist: The Cure by Jo Marchant; The Gene by Siddhartha Mukherjee; The Hunt for Vulcan by Thomas Levenson; The Invention of Nature by Andrea Wulf; The Most Perfect Thing by Tim Birkhead; The Planet Remade by Oliver Morton. We're talking to all the authors over the next 6 weeks before the winner is announced on the 19th of September. The first is Oliver Morton's The Planet Remade: How Geoengineering Could Change the World.
Bee hives have evolved to have a complex, fascinating social hierarchy, and although we know about Royal Jelly and pheromones, how exactly does the queen bee control the fertility of the rest of the hive? A team of New Zealand geneticists, Peter Dearden and Elizabeth Duncan, has finally worked it out.
This Saturday's evening BBC Prom is set in space. The National Youth Orchestra performs The Planets by Holst, and Richard Strauss' Also Sprach Zarathustra. But the concert begins with a piece inspired by this year's detection of Gravitational Waves by LIGO, the Laser Interferometer Gravitational-Wave Observatory. Gravitational Waves composer Iris Ter Schiphorst discusses how she went galactic.

Thu, 04 Aug 2016 - 818 - Dinosaur extinction, Neanderthals in Gibraltar, Music appreciation, A year of New Horizons
The dinosaurs met their end with a massive bang when, 66 million years ago, a 6 mile-wide rock crashed into the Gulf of Mexico. This was bad news for the dinosaurs, and consequently good news for the mammals left behind. Thomas Halliday is a palaeontologist, who specialises on the rise of the mammals, and his new work unpicks what happened to survivors after 75% of the species on earth died.
The Neanderthals were found in Gibraltar back in 1848. Ever since then, teams have been exploring the caves systems on that rocky outcrop of Europe. It's known as Neanderthal City and researchers think it was home to the very last of these people, some 30,000 years ago. BBC science reporter Melissa Hogenboom has just returned from Gibraltar and talks to Adam about the recent findings of abstract art, which suggest that Neanderthals are much more like us than previously thought.
We generally find the combination of notes in a consonant chord more pleasant to our ears than a dissonant one. The question is whether that reaction is learnt or simply part of our biology. It's a tricky thing to test because music is culturally ubiquitous. Neuroscientist Josh McDermott has found a way around this, by playing those tunes to members of a very remote Bolivian tribe - the Tsimane - and gauging their reactions.
One year on since the New Horizons probe zoomed past Pluto, Kathy Olkin, one of the chief scientists behind the mission talks to Adam about how the team have dealt with the new data. Noah Hammond from Brown University explains how he has used photographic data from New Horizons to examine the cracks in the surface of Pluto, and has suggested how they came to be.

Thu, 14 Jul 2016 - 817 - Juno, Space debris, Fake tumours, Risky plants
Earlier this week, the US space agency successfully put a new probe in orbit around Jupiter. The Juno satellite, which left Earth five years ago, had to fire a rocket engine in a tricky and precise manoeuvre in order to brake and become ensnared by Jupiter's gravity. Fran Baganal is a mission scientist for Juno and tells Adam Rutherford what measurements Juno is now in position to make.
Space is full of junk left over from past space missions: from flecks of paint to used rockets, dead satellites, also debris from past collisions of space junk. This junk is speeding around the Earth at several thousand miles per hour. At those speeds even small pieces of rubbish just fractions of a millimetre across can damage communication satellites which are vital for the web, mobile phones, and satellite navigation on earth. The Surrey Space centre team are preparing to launch the world's first space litter-picking mission. The RemoveDebris team share their clean up designs with Adam.
Researchers have had success growing body parts like windpipes and ears in the laboratory for use in transplants. A group of scientists at Barts Cancer Institute in London are making own tumours; tissues we don't want. However, it is important to study how they grow, and co-opt other cells in the body. Reporter Anand Jagatia heads to their tissue lab to see what they've grown.
All animals take risky decisions all the time. The ability to assess the potential gain from the potential harm, and make the right choice, gives the animal an evolutionary advantage. A new study suggests that plants are capable of making similar calculations, despite not having brains. Alex Kacelnik at Oxford University is one of the scientists behind the experiment that suggests that pea plants are willing to gamble.

Thu, 07 Jul 2016 - 816 - Juno, Nanotech art conservation, Robots fix the city, Eel conservation
NASA's Juno Probe arrives at Jupiter on 4th July, where it will execute a daring loop-the-loop in order to get closer to the giant planet than any other spacecraft in history. Juno is constructed like an armoured tank, because Jupiter is surrounded by a belt of very intense radiation that can quickly fry most spacecraft electronics. On July 4, Juno's engines will attempt to slow the probe down so it can be sucked into Jupiter's orbit. The slightest error could mean Juno misses this window, putting an end to the $1.1 billion mission. The man in charge is Dr Scott Bolton, and he speaks to Adam from Pasadena in California.
Traditional art conservation tends to focus on paintings - how to stop paint from peeling. But contemporary art uses a much broader range of materials; plastics, rubber; pickled sharks. This means that an ever-increasing array of techniques are needed to conserve those materials. A new project is looking at the role nanotechnology can play, as Rob Thompson reports.
It's National Robot Week. There is a fear that robots will replace many of the jobs done by humans. But what if robots just stuck to emptying the gutters and fixing potholes; the chores that humans find tedious? Professor Phil Purnell from Leeds University has just launched a project that aims to use robots to fix bits of the city - finding and patching tiny defects before they turn into massive sinkholes.
The European eel may be mysterious, and delicious but it is also critically endangered. The only reason we know this is because of organisations like the Zoological Society of London. They do the unglamorous job of monitoring these fish caught in traps in rivers around the UK. Marnie Chesterton went along to count eels in rainy Brentford with ZSL's Joe Pecorelli, who shares his knowledge of this creature's epic life journey.
Thu, 30 Jun 2016 - 815 - National Insect Week, Venus' electric field, Green mining, Wimbledon grass science
This week is National Insect Week. Almost all animals on Earth are insects, and entomologist Adam Hart told us why we're celebrating and studying them in such detail - particularly diamondback moths, which have recently arrived the UK in large numbers. On the first official (and rather rainy) day of summer, we went down to Butterfly Paradise at London Zoo for the event launch. Entomologist Adam Hart tells us what the Week is all about.
New research out this week suggests that a so called "electric wind" has stripped all the water away from the surface of Venus. Space scientist Glyn Collinson at NASA Goddard Space Flight Centre has led this electrical field study.
Wales has 1300 rivers with illegal levels of heavy metals. Toxic metals like lead, zinc and copper are a legacy left over from when the area was heavily mined. Natural Resources Wales and Innovate UK set a competition to look for technology that would clean up these rivers. One of the winners was Steve Skill from Swansea University, who has come up with some biotechnology that uses algae to suck the poison out of the rivers.
The Championships at Wimbledon start next week, and whatever the weather, the grass has to be perfect. Adam Rutherford headed to London's SW19 to find out how the ground staff are using scientific evidence to cultivate the courts.
Producers: Marnie Chesterton & Jen Whyntie.
Thu, 23 Jun 2016 - 814 - More gravitational waves; Ocean floor mapping; Selfish Gene 40th; Spoonies
Gravitational waves have been detected for a second time. These waves are ripples in the curvature of space time, predicted by Einstein in his General Theory of Relativity in 1916. Back in February, the Laser Interferometer Gravitational-Wave Observatory (better known as LIGO) announced that they had detected the signal of gravitational waves from the collisions of two big black holes. The detection in February was the first observation of these waves, and confirmed General Relativity. This week, LIGO confirm a second detection. BBC Science Correspondent Jonathan Amos explains what is new about these new gravitational waves.
We know more about the surface of the moon than we know about the ocean floor. Admittedly, the sea is much more dynamic, the scene of many chemical and biological processes, about which scientists would like to learn more. This week, cartographers meet in Monte Carlo, to discuss their plan to map the ocean floor by 2030. Roland Pease reports on the ocean-mapping options. 40 years ago, The Selfish Gene, by Richard Dawkins was published. Since then, it has been a perpetual bestseller. In it, Dawkins explains that the gene is the unit of natural selection, an idea that has become central to all biology. Adam Rutherford speaks to Richard Dawkins, and his co-author on ‘The Ancestor’s Tale’ Yan Wong, at the Cheltenham Science Festival, to discuss the impact of The Selfish Gene.
The spoonbilled sandpiper is standing on the edge of extinction, but in good news, Adam hears about of a clutch of eggs laid not in their native Russia but in Slimbridge in Gloucestershire. BBC producer Andrew Luck-Baker visited the Wildfowl and Wetlands Trust’s population back in April, and describes these birds to Adam.
Thu, 16 Jun 2016 - 813 - Fighting Antimicrobial Resistance
This week we're dedicating the whole programme to one of the biggest threats to humanity. We're already at 700,000 preventable deaths per year as a result of antibiotic resistance, and the O'Neill Report suggests that this will rise to 10 million people per year by 2050. Today, we're focussing on the attempts to discover new antibiotics, and alternative therapies for combating bacterial infection. Firstly, we wanted to know why new antibiotics aren't being produced. Dr Jack Scannell, an expert on the drug development economics, told Adam Rutherford why money has been the main barrier.
Most of the antibiotics we use were discovered in the mid-20th century, but as the threat of drug resistant infections increases, the race is on to find new organisms that make novel medicines. We have only identified a tiny fraction of the microbes living on Earth and are "bioprospecting" for useful ones in wildly different locations. Microbiologist Matt Hutchings has been looking to the oldest farmers in the world - leaf cutter ants.
From exotic locations to under your fridge: Dr Adam Roberts runs a scheme called Swab and Send. It's a citizen science project that asks members of the public to swab a surface and send the sample to him – he'll analyse them to look for the presence of new antibiotic-producing bacteria. We joined in the hunt by swabbing spots around the BBC: Adam's microphone, the Today programme presenters' mics, our tea kitchen's sponge, the revolving entryway doormat, and lastly, the Dalek standing on guard outside the BBC Radio Theatre.
Antibiotics are not the only weapon in the war against bacteria. A hundred years ago, a class of virus that infect and destroy bacteria were discovered. They're called bacteriophages. Phage therapies were used throughout the era of Soviet Russia, and still are in some countries, including Georgia. Phage researcher Prof Martha Clokie told us whether phage therapy might be coming to the UK.
Thu, 09 Jun 2016 - 812 - Fixing the Future
We face many global problems, such as drought, flooding and climate change. All of these issues are rooted in science. It'll take politics and people and business to fix them, or for us to manage them, but none of that can happen without a solid scientific base.
In front of an audience at the Hay Festival, Adam Rutherford is joined by Steve Jones, Professor of Genetics at University College London, Marcus du Sautoy, the Simonyi Professor of the Public Understanding of Science at the University of Oxford, and science journalist, Gaia Vince, to discuss what the future holds for humanity and the planet, what we can know, what we can predict, and what is to come.
Adam Rutherford talks to Gaia Vince about the new age of man, the Anthropocene, and the impact it is having on peoples' lives, to Marcus du Sautoy about chaotic systems and when maths can and cannot predict the future, and to Steve Jones about forecasting human population growth and how we are still evolving.
Thu, 02 Jun 2016 - 811 - GM plants; Svalbard Seed Vault; Directed Evolution; Dolphin Snot
The topic of GM plants raises strong opinions and many questions. This week, the Royal Society published answers to some of those questions. Adam speaks to Professor Ottoline Leyser, plant science expert and Head of the Sainsbury Lab in Cambridge. She was involved in writing the responses and Adam quizzes her on the possible issues with GM crops.
Institutes from around the world made deposits to the Svalbard Global Seed Vault this week. More than 8,000 varieties of crops from Germany, Thailand, New Zealand, and the World Vegetable Center arrived at the Vault, located on a remote Norwegian archipelago, to be stored deep within the permafrost. Reporter Marnie Chesterton was there to see it happen, and take a tour of this normally inaccessible place. The Vault is located within the Arctic Circle, and helps to protect the biodiversity of some of the world’s most important crops against climate change, war and natural disaster.
This week Professor Frances Arnold was awarded the Millennium Technology Prize; the Finnish version of the Nobel Prize. Her work is a process called Directed Evolution, and involves creating batches of mutant proteins to see if the mutations make them better at certain functions.
Dolphins use ultrasound to echolocate. Until recently, scientists did not quite know how. Making ultrasonic noises normally requires some hard surfaces such as metal, and dolphins don’t have metal in their blowholes. Acoustic scientists Aaron Thode at the Scripps Institute of Oceanography in San Diego thinks he’s solved this conundrum, and it involves snot.

Thu, 26 May 2016 - 810 - Climate Change, State of the World's Plants, Antibiotic Resistance, Telephone Metadata, Bat Detective
Today we're asking how anyone can make sense of the deluge of climate change data that is almost continually published. By the end of last month, nearly 200 countries had signed up to the Paris climate change agreement, and in doing so they were nominally committing to keep global temperatures "well below" 2C. So now comes the tricky bit: How best to do that - and what is the scientific evidence for policymakers to decide? Climate change expert Dr Tamsin Edwards of the Open University joins Adam Rutherford to help us unpick the research.
Last week a major new report on the State of the World's Plants was unveiled at Kew Gardens in London. There are some 391,000 vascular plants known to science - that's ones with vessels, xylem and phloem - and over 2000 were discovered last year alone. But just over a fifth of all plants are estimated to be threatened with extinction - and global climate change forms part of this threat. Our reporter Cathy Edwards met Professor Kathy Willis, Director of Science at Kew, to find out how plants are responding to the changing climate, and also spoke to Professor Yadvinder Malhi, Oxford University, and Kay Havens, Chicago Botanic Garden.
The Review on Antimicrobial Resistance, headed by economist Jim O'Neill, was published today. Molecular microbiologist Professor Matt Hutchings from the University of East Anglia, gave us a brief summary.
A new paper out this week looks into exactly what the act of making a phone call can reveal. The study, which was led by Patrick Mutchler and Jonathan Mayer at Stanford University in the States, is the culmination of work looking into what metadata really can show - you may have seen reports of some of their findings, as they've been revealing them in the public interest since 2013. They collected metadata volunteered by 823 participants, in total, more than 250,000 calls, and 1 million text messages. Steven Murdoch from the Information Security Research Group at University College London joined us to put this into context.
As part of the BBC's Do Something Great season celebrating volunteers, Adam joined Professor Kate Jones from University College London on a Hampstead Heath bat watch, part of the citizen science project Bat Detective.

Thu, 19 May 2016 - 809 - Genetics and education, Eyam plague, Pint of science, Labradors and chocolate
The biggest study of the relationship between genes and educational attainment - in this case, basically the measure of how long you stay in education - has been published this week. A huge number of environmental factors influence this trait, but genes also play a small role. In the new study, a large team of researchers looked at over 300,000 people and identified 74 genetic variants, slight differences in our DNA, that do seem to associate with how long those individuals stayed in formal education. Senior author Dan Benjamin, University of Southern California, and social genetics researcher Eva Krapohl from Kings College London helped steer us through this complex quagmire.
The Derbyshire village of Eyam is famous amongst Plague historians because when the disease arrived in a bale of cloth in 1665, the local vicar took a bold step and quarantined the whole village. 260 villagers died, but the sacrifice is thought to have saved surrounding populations. This noted event yielded a rich data set, which Eyam residents Francine Clifford and her late husband John meticulously mined over the last few decades. When epidemiologist Xavier Didelot of Imperial College London visited the local museum whilst on holiday, he couldn't resist investigating.
Later this month, in pubs around Britain, and bars in 11 other countries, audiences will gather to hear about everything from black holes to cancer treatments - all part of a phenomenon called 'Pint of Science'. Marnie Chesterton went to The Castle in Farringdon to hear more.
Finally, last week we met Poppy, one of the Labradors likely to have a newly discovered genetic reason for eating her owners out of house and home. Poppy's most notable devouring was of a large birthday cake, resulting in a trip to the vet's to get her stomach pumped. A fellow cake-eating-Lab-owning listener got in touch to ask why this procedure was necessary. It all comes down to the flavour of the cake: Chocolate.

Thu, 12 May 2016 - 808 - Human embryos, Transit of Mercury, Fishackathon, Fat labradors
In a major advance in the field of embryology, scientists this week have kept human embryos alive in petri dishes for record amounts of time. The legal limit for keeping fertilised human embryos in the lab is 14 days, a cut-off point set in 1979. Back then, scientists were able to keep embryos alive for only a few days, meaning the limit was only a theoretical one. Advances mean that this week, in 2 papers, researchers have reached that limit. Professor Ali Brivanlou, Robert and Harriet Heilbrunn Professor of Stem Cell biology and molecular embryology at Rockefeller University is lead author on one of the papers, and Professor Bobbie Farsides is a clinical and biomedical ethicist at Brighton and Sussex Medical School. They join Adam to discuss the next steps for embryology. Should this limit curtail research?
Next Monday is the transit of Mercury. 13 times a century, Mercury passes directly between us and the Sun, and creates a pinprick shadow, a pixel of black for about 8 hours. This strange planet has no atmosphere, but a lot explosive volcanic activity. It has an eccentric orbit - meaning its distance from the sun fluctuates wildly. A Mercury year is 88 Earth days, but a Mercury day lasts almost two mercury years. David Rothery is a professor of Planetary Sciences at the Open University. He reveals how scientists study this planet and explains how, and how not to view the transit of Mercury.
Overfishing is one of the biggest threats to the health of our oceans. According to the UN, up to a third of the world's fisheries are overexploited or depleted. It is a huge complex problem with many inputs and outputs to compute. So who better to tackle it than a team of hackers? Recently, coders around the globe gathered to take on the challenge, in a 48-hour Fishackathon. Reporter Anand Jagatia went along and reports back to Adam
Most dog lovers will know that Labradors are particularly keen to eat anything, all the time, at any time. As a result, some are a bit corpulent, even obese. The cause is likely to be in their genes. A new study in the current issue of Cell Metabolism has identified that genetic basis for the perpetual hunger. Eleanor Raffan from Cambridge University, geneticist and vet, led the study. She explains to Adam how she gathered a cohort of dogs.
