    The Democratisation of Space?

    New Zealand is third in the world for the number of orbital rocket launches from our shores, sitting just behind the US and China. Phil Vine discovers some of the challenges raised by our push into the unknown and how it is changing the final frontier. Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: Through a science experiment on the ISS, New Zealand researchers have been taking advantage of the unique conditions in low earth orbit to investigate commercial opportunities. While New Zealand is well known as a place from which to launch rockets, we do not have a lot of our own hardware in space (the University of Auckland does have TPA-1 CubeSat). But that might be about to change.Tech bros turned space bros like Elon Musk are making big waves out in orbit. The latest news is that Musk is hoping to harness the sun through satellites to power AI data centres.The New Zealand government's biggest investment in an international space mission ended in failure last year after MethaneSAT, a satellite built to detect methane emissions around the world, lost contact. While there are challenges inherent in humans and their technology being in space, that’s not all that is going on. Scientists are keeping a close eye on an active black hole and bright lights have Northland locals turning their eyes to the skies.Guests: Mark Rocket, CEO Kea AerospaceDr Priyanka Dhopade, senior lecturer in mechanical and mechatronics engineering, University of AucklandDr Tuana Yazici, space law expertGo to this episode on rnz.co.nz for more details

    Science for future fashion

    We know there are issues with sustainability within the fashion industry - can science help create a better future? Claire Concannon visits the Bioeconomy Science Institute in Rotorua to learn how New Zealand scientists are contributing to a massive multi-national project aimed at shaping the textile industry of tomorrow. Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: UPWEARS has their own research project page if you want to learn more.Learn more about how the Bioeconomy Science Institute (formally Scion) is figuring out how to make new materials and products using bio-waste products rather than fossil fuels.The rise of synthetic fibres impacted the wool industry here in New Zealand, although some entrepreneurs and weavers are making it work for them.Guests: Dr Yi Chen, Bioeconomy Science Institute, and UPWEARSDr Robert Abbel, Bioeconomy Science Institute, and UPWEARSSean Taylor, Bioeconomy Science Institute, and UPWEARSLouise Le Gall, Bioeconomy Science Institute, and UPWEARSDr Kate Parker, Bioeconomy Science Institute, and UPWEARSGo to this episode on rnz.co.nz for more details

    Going for eradication - Predator free South Westland

    Since 2018 there's been a massive effort underway to clear over 110,000 hectares of South Westland of possums, rats and stoats. As the pest numbers have dropped the native flora and fauna seem to have flourished. The eradication stage is now nearing completion, and the focus is switching to maintenance. What will it take to keep the pests out long-term? And what can be learned from this large-scale project that could be used elsewhere in Aotearoa? Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: Read/Listen to the rest of the reports from Tess Brunton’s reporting trip to the West Coast, about the eradication project, the work of species dogs, the feedback from tour operators and how rowi, New Zealand’s rarest kiwi, has been helped come back from the brink.For more on the use of AI in pest management project, listen to how the Southern Lakes Sanctuary team have been making use of it at Wye Creek.Guests: Chad Cottle, Predator Free South WestlandEthan Perry, Predator Free South WestlandNate St Hill, Predator Free South WestlandPouri Rakete-Stones, Predator Free South WestlandDion Arnold, White Heron Sanctuary ToursGo to this episode on rnz.co.nz for more details

    Insect vibes

    Some insects communicate using a secret language that we can’t sense – a language of vibrations. Now researchers at the Bioeconomy Science Institute are starting to decode what insects are saying to each other. They hope to harness this knowledge to develop new, chemical-free methods of pest control to help farmers and growers. Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: Insects can also be recruited to help. For example, insects can be released into New Zealand for biocontrol in the effort to combat invasive weeds.While we often talk about the impact of invasive mammals on New Zealand’s bird life, they are also a problem for native insects too.We’ve got some invasive pest spiders here too, but researchers are trying to figure out if they can trap them by developing a special spider perfume.Guests: Dr Mark MacDougall, Bioeconomy Science InstituteDr Lloyd Stringer, Bioeconomy Science InstitutePete Mundy, Castle Rock OrchardsDr Rachael Horner, Bioeconomy Science InstituteDr Bethan Shaw, Bioeconomy Science InstituteGo to this episode on rnz.co.nz for more details

    Sight in the womb

    When do humans begin to interact with the world, and develop our sense of self? When we are born? Or might it start even earlier than that? Our visual systems are a key way that we perceive the world. New findings from the University of Waikato have shown that light can enter the womb and that we might already be learning about the world before we arrive in it. Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: Listen to Our musical minds to learn why, to psychologists, humans’ musical ability is just weird.Like our sense of vision, our ability to hear also involves physical inputs from the world around us combined with the processing and prior knowledge of our brains. But sometimes things can go a bit awry, such as happens for those with tinnitus.Our visual system is evolved for daylight, but what about those creatures that live in the deep darkness, such as squid.Professor Vincent Reid’s early research in this area was covered by RNZ podcast ‘This Way Up’ in 2017.Hear more from William Ray in the award-winning Black Sheep podcast series, or in a recent Our Changing World episode about the Flowers of the Underworld.Guests: Professor Vincent Reid, University of WaikatoAssociate Professor Jacob Heerikhuisen, University of WaikatoWilliam Ray, Janella Espinas, James Espinas RayGo to this episode on rnz.co.nz for more details
