A moon beyond our Solar System, dust storms on Mars and questioning of reality

Your phone battery doesn't like being fully charged or discharged. This is why it's sometimes advised that to extend its life, you shouldn't charge your phone beyond 80 per cent, or let it drop below 20 per cent.But what's actually happening inside a lithium-ion battery to cause this effect, and what does it mean for battery engineering — and the life of the battery in your phone, or your electric car?Jonathan Webb powers through the chemistry of batteries with Professor Neeraj Sharma.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

Millions, perhaps billions of sharks teeth lie on the ocean floor. Valuable mineral deposits collect on their fossilised remains. Now they are viewed as a resource and if exploited devastation will come to an little known ecosystem.

Deep in an old gold mine in South Dakota, scientists witnessed a flash of energy in a giant pool of xenon. Some in the astronomical community are pretty excited, saying this is our best hint yet at what dark matter is. How do we know, why does it matter — and what happens next?Jonathan Webb shines a light on dark matter with Dr Theresa Fruth, who was involved in the potential discovery.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

Plus the tree bark which hosts a whole world of methane-absorbing microbes.

AI is getting so good at maths that it is now tackling, and apparently solving, some of the hardest mathematical problems that exist. But as huge companies like OpenAI and Anthropic race to outdo each other, human mathematicians are getting caught in the crossfire... and their field is changing forever. Jonathan Webb speaks to ABC AI Technology Reporter Cam Wilson about the furore over the Navier-Stokes equations and the million-dollar Millennium Prize.Featuring:Cam Wilson, AI Reporter at ABC.Professor Tristan Buckmaster, Mathematician at New York University.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

It's been three months since the first case of bird flu was found on the Australian continent.Many cases have been found in birds since then, along with other mammals. So where has it spread? And what can we expect to see as spring and summer arrive?Jonathan Webb speaks with Peter de Kruijff, who's been following bird flu since the very beginning.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

The Science Show gives Australians unique insights into the latest scientific research and debate.

Most people know the feeling of ticklishness, whether it's the tickle attacks that bring about uncontrollable laughter or the feather-like touch from something brushing against your skin.But why do we feel ticklish? Can we stop it? And why did we — and all our ape cousins — evolve this sensation?Jonathan Webb speaks to Dr Anina Rich to explore the science of this everyday experience.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).
