It’s been almost 30 years since a team joined forces to investigate a particularly aggressive form of stomach cancer that was afflicting one Tauranga whānau. Kimi Hauora Health and Research Clinic in Tauranga and University of Otago geneticists together found the cancer-causing genetic change, helping save thousands of lives worldwide. Justine Murray is at Mangatawa Marae with Maybelle McLeod and Erin Gardiner to reflect on that time, and Professor Parry Guilford discusses those first formative years.
This week, we’re hanging out in the terahertz area of the light spectrum. Sandwiched between infrared light and microwaves, terahertz has been the long-forgotten cousin of the light family. But no longer! At the Australian Synchrotron, intense and focused beams of terahertz light are used to test new materials for carbon capture, clean energy applications, and the next generation of computing.
Electrons! High speeds! Intense beams of light! Claire Concannon takes a tour of our nearest particle accelerator – the Australian Synchrotron in Melbourne. Designed to create high-energy x-ray light useful for science, the synchrotron enables an incredible diversity of research. And, because of long-standing funding support, New Zealand scientists can also use it. Claire finds out what interesting research questions some visiting New Zealanders are shining a light on.
Advances in the field of genomics (the study of DNA and genomes) have meant big leaps in our ability to sequence, understand and manipulate the genomes of living things. Damian Christie explores research happening now in New Zealand in this area.
Plus, with a recent announcement that the government is introducing new legislation, what’s next for the regulation of gene technologies in Aotearoa?
Wastewater testing became part of our daily lives during the Covid-19 pandemic, but what else can it tell us about what’s happening in our communities? From looking for illicit drugs, to monitoring alcohol consumption and health biomarkers, Claire Concannon meets scientists tapping into the rich research potential of what’s in our pee.
They will look like fish, swim like fish and even sense like fish. Liz Garton meets a research team designing robofish and smart wetsuits to monitor the state of our oceans.
Making and processing music is something unique to human brains, says Dr Sam Mehr. But why are we so attuned to rhythms, melodies and matching tones? Claire and Sam take a deep dive into the universal language of music, and how our minds make sense of it.
Claire Concannon and Dr Andrew Digby talk about all things kākāpō: that habitat trial and where the birds are now, the next breeding season, and Andrew's hopes for the future of this iconic manu.
In July 2023 four male kākāpō were released into the fenced Sanctuary Mountain Maungatautari - part of a new habitat trial to investigate suitable locations for the growing kākāpō population. But after a further six were introduced, the kākāpō began to wander - beyond the fence. A year on, and several escapes later, what's been learned? And what's next for kākāpō in Maungatautari?
An expedition to the Bounty Trough off the Otago Coast uncovers a treasure trove of deep-sea creatures - including some species new to science. Veronika Meduna meets slimy fish, snails, and tiny shrimp-like critters from the ocean depths.
Avocado seed powder to make snacks, fish waste skin for wound healing, and bioactive compounds made from brewer's spent grain - Claire Concannon visits a food lab at AUT turning food waste into wealth.
Climate-change-induced sea level rise is happening. What will this mean for our low-lying wetlands? Will they get eroded away - releasing more carbon? Or will they grow at the same rate, and hold their ground? And what will this mean for the critters that live there? A team are investigating at an Otago wetland that might be the first in New Zealand to make this change.
We might think deep-sea squid look a bit strange, but if they have the capacity for it, they would likely consider us monsters! Claire speaks to a squidologist and a PhD candidate about their research trying to understand more about the lives of deep-sea squid.
Jump onboard an alpine flight to photograph some glaciers! The annual snowline survey has been running since 1977, but today new techniques are allowing researchers to go beyond 2D photos to make 3D models of the glaciers. Claire Concannon joins the team for a long day of flying and photographing.
A new six-part video series highlights the state of our oceans, and efforts from researchers, Māori and other partners to develop sustainable solutions.
Māori and Pacific peoples are three to six times more likely to develop stomach cancer than New Zealanders with European ancestry. Claire Concannon visits a research team taking aim at this disparity.
Aotearoa is a country plagued by pests, but conservationists are hoping advances in drone technology could turn the tables. Producer William Ray looks at how drones are being trialled in controlling everything from microscopic diseases to elusive wallabies, and wilding pine trees.
Caves created by rivers of lava underlie New Zealand's biggest city. A new research project is documenting Auckland's lava caves, hoping to protect this hidden geological heritage and understand what future eruptions might have in store.
A deadly frog fungus has decimated frog populations around the world, but frog biodiversity hotspot Papua New Guinea remains untouched - for now. In this episode of ABC podcast Pacific Scientific, James Purtill discovers the amphibian treasures of the world's largest tropical island, and what conservationists are doing to protect them.
This week, Phil Vine dives into the science of climate attribution. How much is climate change affecting extreme weather events? And how can this new science prepare us for the future?
