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.

Lab Notes: Have we found dark matter?

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:<ul><li>Cam Wilson, AI Reporter at ABC.</li><li>Professor Tristan Buckmaster, Mathematician at New York University.</li></ul>You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).
