Revisit the frozen continent with us in this mini rerun of the Voices from Antarctica series. This week, Alison visits Cape Crozier to meet a colony of emperor penguins and the team of scientists studying them.
Thu, 06 Oct 2022 - 28min - 1779 - The prickly prize of ongaonga
It's spectacularly spiky and delivers a painful or even deadly sting. Why are a team of conservationists growing and planting up Orokonui Ecosanctuary near Dunedin with more and more native tree nettle, ongaonga? It's all because of a pretty little pollinator called the kahukura, or red admiral butterfly, and its prickly preferences. Claire Concannon visits Orokonui to learn more about the ongaonga-kahukura relationship, as well as new research investigating whether these native butterflies are the victims of a sneaky ecological 'trap'.
Thu, 29 Sep 2022 - 34min - 1778 - A send-off for SOFIA, the flying observatory
We're saying farewell to the Stratospheric Observatory for Infrared Astronomy (aka SOFIA) this month. The mission, which was partially based in Christchurch, wraps up after a decade of observing comets, stars, planets, and the moon. In July 2017, Alison Ballance boarded the Boeing 747 with a flying telescope for one of its research flights.
Thu, 22 Sep 2022 - 30min - 1777 - Future forest industry
In a future that is free of fossil fuels, where will we source all the products that we get from the petroleum industry? Scientists at the forest research institute Scion think that trees might provide the solutions we need.
Thu, 15 Sep 2022 - 26min - 1776 - Fascinating fungi and pesky pathogens
In a room in the Manaaki Whenua building in Auckland are rows and rows of shelves, with cardboard boxes containing an array of weird and wonderful dried fungi. Claire Concannon visits to learn how and why these specimens are kept, and finds out about its sister culture collection, which is helping in the defense against invading plant pathogens.
Thu, 08 Sep 2022 - 31min - 1775 - Bringing back nature to Nelson
Alison Ballance visits the Brook Waimārama sanctuary, and discovers that the old saying "many hands make light work" is particularly true when it comes to community conservation. A relatively new fenced sanctuary, the Brook Waimārama team is now at the exciting stage of bringing native wildlife back into the area, including orange-fronted parakeets – kākāriki karaka – and giant land snails.
Thu, 01 Sep 2022 - 29min - 1774 - Plasma jet technology and encouraging Pacific students in science
Claire Concannon catches up with Dr. Taniela Lolohea of Auckland University of Technology. He is researching in the relatively new field of low temperature plasma surface coatings, and explains how it can be used to create customised surfaces for many purposes. But he is also investigating ways to encourage more Pacific students in science, including by developing projects that might be more attractive for them.
Thu, 25 Aug 2022 - 30min - 1773 - Investigating the virosphere
While we might have heard all we ever want to know about viruses in the last few years, the truth is, known viruses represent less than zero point one percent of the estimated total of viruses out there. Claire Concannon meets a team from the University of Otago trying to increase our knowledge of virus diversity, so that we can better understand their evolution.
Thu, 18 Aug 2022 - 26min - 1772 - For the love of seabirds
Edin Whitehead inherited a love of birds from her father and became captivated by the majesty of seabirds on a trip to the Subantarctic Islands. Now a PhD student at the University of Auckland, she is trying to figure out how best to help the birds of the Hauraki Gulf, who are facing many threats, including warming waters.
Thu, 11 Aug 2022 - 27min - 1771 - The Living Laboratories project
The Auckland University of Technology Living Laboratories project is all about investigating how best to grow back native forest. At Pourewa creek, this collaboration between AUT and Ngāti Whātua Ōrākei involves planting blocks with different nursery plants and measuring individual tree growth and biodiversity indicators over time. They hope to figure out the recipe to cheaper and faster regeneration of native bush.
