And genetics reveals further details of a great friendship story – humans and dogs.

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.

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.
