A team from Caltech is using ultrasound to reveal processes at work one kilometre under Antarctic ice. 

AI chatbots are helping to crack long-standing mathematical problems, including some of the famous Paul Erdős conjectures that have remained unsolved for nearly 80 years. It's not just researchers finding these solutions, either: it's also amateur mathematicians armed with off-the-shelf ChatGPT.Jonathan Webb wheels out the chalkboard with Dr Melissa Lee to discuss how AI is shaping the field of ma...

We visit a wildlife sanctuary north of Canberra where enclosures are being built to quarantine the eastern quoll, a species already endangered. Will it work and is this a long-term solution?

Old satellites and bits of space junk regularly fall back to Earth, burning up as they pass through the atmosphere. All this burning metal causes a chain reaction and ultimately destroys ozone molecules, which keep us safe from most of the Sun's harmful UVB rays. Could a new era of satellite "megaconstellations", like the one run by SpaceX's internet company Starlink, undo humanity's hard work rep...

We also celebrate mathematician Terence Tao’s King’s birthday honour, and go in search of subatomic particles, 2Km underground.

A deadly variant of H5N1 avian influenza has finally reached mainland Australia: the last continent without it. Although the risk to human health remains low, this virus has spread through many different species overseas — and not just birds. So are our animals vulnerable? Jonathan Webb speaks with Dr Tiggy Grillo about which animals could be at risk, and what is being done to protect them. You ca...

If insects feel pain, do they deserve animal rights as apply to mammals?

The largest, deepest and oldest whale graveyard has been found off the coast of Western Australia: teeming with life.  Jonathan Webb takes a deep dive with environment reporter, Peter de Kruijff, into the science behind whale falls and their importance to underwater ecosystems.

What might be the biggest threat to tropical forests? Climate change? Illegal loggers? Invasive species? None of the above. It’s roads. Bill Laurance explains.

On an island full of trees, there can only be one that is the tallest. How did researchers in Taiwan manage to find the tallest tree in East Asia? This week, Jonathan Webb finds this out by speaking to Dr Rebecca Hsu, the lead researcher behind the project to find The Heaven Sword.

Evidence is mounting that Indigenous people were in Australia early than the 65,000 date most now know. And there are suggestions the continent supported a population of at least 2 million people. Authors Sean Ulm, Billy Griffiths and Larissa Behrendt explore these ideas in their book The First Inventors.

Plants are more aware of their surroundings then we give them credit for. A growing body of work is showing that plants can change themselves in response to different sounds. Dr Samarth Kulshrestha, a molecular biologist from the University of Canterbury, is one of these researchers, looking at the mechanisms behind plant senses.  You can binge more episodes of the Lab Notes podcast with science e...

AI offers instant translations between human languages. So will we one day communicate with whales? And while we marvel at the possibilities, the challenge today is preventing collisions between sea creatures and ships, or whales and turtles becoming tangled in nets.

Ever wondered how your sweater became bright orange, or how your leather shoes were made? Chances are, at some point in the process, hazardous chemicals like lead or azo dyes were used.  Jonathan Webb speaks to Ellen Phiddian, science reporter with Radio National, about whether these chemicals are dangerous to us, and if we should be worried about them.  You can binge more episodes of the Lab Note...

The IOC will test athletes for a sex gene. But as Jenny Graves explains, human genomics is diverse. Some athletes may be genetic exceptions and will need to be handled with care and sensitivity.

A new giant dinosaur has been uncovered in Thailand: the largest ever found in South-East Asia. More than 100 million years ago, Nagatitan towered over the Earth — and has now been described by a team of researchers from the UK and Thailand.   Jonathan Webb speaks with Thitiwoot Sethapanichsakul, a PhD student at University College London who was part of the team that discovered and named this pre...

Belinda Smith reports on the winners and losers in science following the federal budget brought down this week by treasurer Jim Chalmers.

Stories of AI chatbot users drifting from our shared reality are increasingly common, often described as cases of AI delusions, delusional spirals, or AI psychosis. New research from Stanford University and the Human Line Project investigates the mechanisms behind these delusions, asking whether AI is making people more delusional or whether these chatbots are simply agreeing with delusional think...

The much-loved naturalist David Attenborough is 100. And still working!

The Atlantic Meridional Overturning Circulation (AMOC) is a vast current that helps move water and energy right around our planet, from top to bottom. Scientists say it is slowing down — and might stop altogether, with dire consequences for the global climate if it does.  So how do major ocean currents work, why is it slowing down, and what will happen if it collapses?

Australia’s research potential is not matched by funding. Belinda Smith speaks to scientists impacted and science minister Tim Ayres responds.

The Kimberley region is more than 2000 kilometres north of Western Australia's capital city, Perth. The area is both extremely remote and extremely beautiful. So why is it the proposed location for Australia's biggest "AI factory"? Why do we need this massive AI data centre? And are these factories likely to be built in other remote parts of Australia?  You can binge more episodes of the Lab Notes...

Despite the many benefits from a multi-country collaboration on a major astronomy project, Australia will not be part of the European Southern Observatory after 2027.

Australians were captivated by the recent Artemis II mission — and they’re hungry for more. New YouGov polling reveals surging national interest in space exploration and its future. You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia). You'll find episodes on animal behaviour, human health, space exploration and so m...

Secretions from hookworms are being used to develop treatments for autoimmune diseases which include food allergies.
