  • 57 - Czech Republic's First 3D-Printed House Built in 48 Hours

    Welcome to the World news. World news keeps you updated news around the nations.

    Today's topic is "Czech Republic's First 3D-Printed House Built in 48 Hours"

    The Czech Republic's first 3D-printed house takes just 48 hours to build, a few weeks to dry, and is designed to last at least 100 years.

    Designed by artist Michal Trpak with the support of a Czech building society, the first "Prvok" house has been built in the southern Czech city of Ceske Budejovice.

    The Prvok house was designed with 43 square meters of floor space and three rooms: a bathroom, a living room with kitchen, and a bedroom. It can be used in both the city and countryside, and can even float on water.

    According to the building society, 3D-printed houses can be built seven times faster than regular houses, and the costs can be up to 50% lower. Also, 3D-printing homes creates up to 20% less carbon dioxide than building with bricks.

    The house uses environmentally friendly technologies like a shower that can collect, clean and reuse water, and a roof where plants can be grown. And even though it has been designed to last for a century, Trpak says that owners can demolish the house if they don't need it anymore, and print something new at the same place using the same materials.

    The house was printed by a robot arm developed through one of Trpak's other projects, called Scoolpt. Working with global company Master Builders Solutions, Scoolpt also developed the concrete that the Prvok house is made of. After just one day, the concrete is as strong as the foundations of a normal family home — but after 28 days of drying, it is as strong as the concrete used to build bridges.

  • 56 - Balloon to Fly Tourists to Edge of Space

    Welcome to the World news. World news keeps you updated news around the nations.

    Today's topic is "Balloon to Fly Tourists to Edge of Space"

    Two companies, Space Perspective and PriestmanGoode, are working together to make a balloon that will fly passengers to the edge of space.

    The balloon, known as Spaceship Neptune, will use hydrogen to float up over 30 kilometers, more than twice as high as a passenger plane. Below the balloon, there’s a capsule with seats for eight passengers and one pilot.

    Nigel Goode, Designer and Co-Founder of PriestmanGoode, said that the companies want to make the journey as comfortable as possible for passengers. There’s a bar and a bathroom, plus large windows so passengers can see space and the Earth below. They’ll even be able to share the experience on social media while on board.

    The journey will take six hours in total. It will take two hours for the balloon to float to the edge of space, where it will stay for two hours. It will then return to Earth and land in the ocean, where a boat will collect it.

    Space Perspective says that it hopes the experience will be as easy as boarding a plane.

    The first flights will leave from Space Perspective’s control center in Florida, but there are plans to have more flights from Hawaii, Alaska and possibly other places outside of the US.

    The companies hope that the balloon will be used for experiments by scientists and for events like weddings, concerts and business meetings.

    The first test flight is planned for early 2021, but won’t include any passengers. The companies hope to eventually offer up to 100 flights per year.

  • 55 - Japan's Fugaku Supercomputer is Helping Fight COVID-19

    Welcome to the World news. World news keeps you updated news around the nations.

    Today's topic is "Japan's Fugaku Supercomputer is Helping Fight COVID-19"

    Scientists around the world are trying to find effective treatments for COVID-19, and they're getting extra support from Fugaku, a Japanese supercomputer.

    Fugaku — also another name for Mount Fuji — is kept in Kobe, Japan. Its installation began in December 2019, and even though it is not scheduled for full operation until 2021, it has been helping with coronavirus research since April 2020.

    The supercomputer has identified dozens of possible treatments for COVID-19. Researchers from Kyoto University used it to run molecular-level simulations on 2,128 existing drugs. Over ten days, it looked for those that can bond with proteins associated with the novel coronavirus and inactivate them.

    The dozens of drugs it identified include 12 that are already being tested around the world to treat the virus, but also a number that have not yet been looked at by scientists.

    Research company Riken, which developed the supercomputer with Fujitsu, have also used it to model how the virus could travel through the air in different places. Findings from that study suggest that keeping the windows on commuter trains open and limiting the number of passengers could reduce the risk of infection.

    Among the other research projects that could use Fugaku are those trying to find previously unknown characteristics of the still very new virus. The supercomputer could also be used to better understand the socio-economic impact of the pandemic, and contribute to countermeasures against the spread of the virus.

    In June 2020, Fugaku was named the world's fastest supercomputer. It can perform 415 quadrillion computations a second, which is 2.8 times faster than the former fastest supercomputer, the Summit system from the US.

    Fugaku is set to play a part in helping Japan achieve the goals in its Society 5.0 plan, which looks to use technology and data to balance economic growth with resolving social problems. Other than helping with medical science, it could be used to better predict natural disasters like earthquakes, or help with the development of clean energy.

  • 54 - Study: Young Children Are Using Apps Meant for Adults

    Welcome to the World news. World news keeps you updated news around the nations.

    Today's topic is "Study: Young Children Are Using Apps Meant for Adults"

    Some children as young as 3 years old use apps on mobile devices that are intended for adults, according to a study published in the journal Pediatrics.

    The study used an app called Chronicle for Android devices, and screenshots of the battery page for Apple devices, to see app use information for 346 children aged 3 or 4. Of the 346 kids, 121, or about 35%, had their own device. The rest were using their parents' devices.

    Parents were also asked how much time they thought their kids spent using the devices.

    The study found that while some apps were age appropriate, others were gambling apps, like Cashman, or violent ones like Terrorist Shooter or Fortnite.

    Many children also used "general audience" apps, like Cookie Jam and Candy Crush. Players can spend real money in these games, and children's privacy could be at risk because the apps may not restrict the data they collect or sell to advertising companies.

    The study also found that most parents were wrong about how much time their kids spent using mobile devices. Fewer than 30% of parents estimated the time correctly. About 36% underestimated how much time their kids spent on their devices, and about 35% overestimated, with the parents' estimates being off by an average of more than an hour.

    "Another interesting finding was how much YouTube dominated the viewing habits of so many 3- to 4-year-olds," said Dr. Jenny Radesky, the study's lead author. "Finally, we found a few kids with their own devices who had them running into the middle of the night — until 3 or 4 a.m. at times, usually [on] YouTube."

    Other research has found that most kids are using devices with screens from infancy. There is also evidence that kids aged between 3 and 5 who have more than an hour a day of screen time without their parents involved have less brain development in the areas that control language and thinking skills.

  • 53 - Museum of Underwater Art Opens in Australia

    Welcome to the World news. World news keeps you updated news around the nations.

    Today's topic is "Museum of Underwater Art Opens in Australia"

    The new Museum of Underwater Art is now open in Australia’s Great Barrier Reef. The museum is two hours by boat from Townsville, Queensland, and is 18 meters below the ocean’s surface.

    The museum features sculptures from British artist Jason deCaires Taylor. Taylor created the world's first underwater sculpture park in Grenada in 2006, and has made other underwater museums in Mexico and Spain.

    The new museum hopes to get people thinking about climate change and protecting coral reefs. It is made out of material that helps new coral grow, and also provides a home for underwater wildlife.

    The largest sculpture, Coral Greenhouse, weighs more than 58 metric tons and is the first underwater building by the artist. Inside, there are places for fish and other wildlife to live and hide, as well as 20 sculptures of children. Doorways allow divers to swim into the building.

    Another sculpture, Ocean Siren, is just 30 meters from the Townsville coast. It is of an indigenous girl from the local community, and is the only sculpture in the museum that can be seen above the surface. Lights on the sculpture change color depending on the water temperature, showing the rising sea temperatures in the area.

    The museum will create 182 jobs for the local community, and is expected to bring 50,000 visitors to Townsville each year. Several more sculptures will be added in 2021.
