Ngutukākā, or kākābeak, is a popular garden plant in Aotearoa. But in the wild, it is now rarer than kākāpō, with only about 100 individual plants surviving on steep, inaccessible cliffs. The East Coast is one of its remaining strongholds and the Tairāwhiti Ngutukākā Trust is on a mission to bring the taonga back. Veronika Meduna joins the inaugural Tairāwhiti Ngutukākā Festival to find out more about the community’s efforts to turn State Highway 35 into a Crimson Highway by rewilding this...

Invasive redback spiders are highly venomous, threatening both people and New Zealand’s native species. A team of scientists is developing a cunning tool to trap male redbacks, by concocting an irresistible spiderweb perfume. We visit 800 captive redback spiders in the lab, learn about their wild mating habits, and check out the “spider arena” where the redbacks’ signature scent is put to the test.

The MRI technique advances coming out of the Mātai Medical Research Institute in Gisborne have been described as ‘pioneering’, ‘groundbreaking’ and ‘world leading’. Claire Concannon speaks to chief executive and research director Dr Samantha Holdsworth to learn why, and about their big plans for the future.

About two hours south of Dunedin, in the Catlins, the Tautuku and Fleming rivers flow into the sea at Tautuku beach. Covered in native bush from headwaters to the ocean, this special catchment is home to many native, and some threatened, plants and animals. But there’s an ongoing battle. Browsing animal such as deer and pigs are destroying the undergrowth, while feral cats and stoats are predating on critters such as the mātātā, the South Island fernbird. We meet some of the people fighting...

Every year in New Zealand, recreational hunters shoot more than half a million wild game. Most are shot with lead-based ammunition. Now, researchers are investigating what happens to that lead, and how much of it is getting into the food chains of humans and the endangered kea. Alison Ballance speaks to scientists at Nelson-Marlborough Institute of Technology, and kea conservationists and predator control experts at the Department of Conservation to learn more.

To keep their eggs safe, some birds build simple cup-shaped nests. Others craft elaborate fully enclosed domes, with porches, fake entrances and ledges. But is this intricate construction of nests a set, encoded behaviour? Or can birds adapt in different conditions? Researchers are keen to learn about flexibility in nest design, to better understand how different species might be able to respond as the climate changes.

Almost 40 years on from the first reports of the Antarctic ozone hole, and 35 years since the Montreal Protocol to ban CFCs came into effect, what’s going on with the ozone hole? How does it form? How do we measure it? And having solved the CFC problem, why are we still monitoring ozone so closely? Claire Concannon heads to NIWA's Atmospheric Research Station in Lauder, Central Otago, to find out.

We love our four-legged friends. It’s estimated about a third of New Zealand households share their home with at least one dog, and two thirds of dog owners consider their furry friends to be family members. Some dogs work, others keep us company, make us laugh, get us walking twice a day, and shower us with unconditional affection….. But are we looking after all their needs? Claire Concannon speaks with a dog welfare expert about the science behind how we know our dogs love us, and what to...

We all experience anxiety – when our brains look into the future and imagine bad things happening. It’s normal and has helped keep us alive as a species. But levels of anxiety are rising, particularly in young people, and at the severe end of the spectrum clinical anxiety prevents people from going about their lives. This Mental Health Awareness Week we meet a team of researchers at the University of Otago investigating the brain-body connection in anxiety, and how different potential...

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...

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?

It's been one year since kakapo returned to mainland Aotearoa at the fenced Sanctuary Mountain Maungatautari. Claire Concannon finds out what mischief they've been up to, and what's next for the iconic parrot.

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.

Claire Concannon heads along to the food technology lab at the Auckland University of Technology to speak with one researcher who is aiming to turn 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.

Claire Concannon visits an Otago wetland to meet those investigating its future as sea levels rise.
