The
Naked Scientists

It's 150 years since Darwin's theory of Evolution was presented to the Linnean Society, and so we've Naturally Selected the Science of Evolution! We find out why scientists have revisited a textbook example of natural selection in action, find out why horny sheep are gambling on good weather and how bacteria in the lab can evolve into a new species! We find out why tragedy almost kept Darwin's ideas from ever being seen, by looking at the archives of his own letters. Plus, why crocodiles chat from inside their eggs, a new way to send messages underwater and why Martian soil would be good for growing cabbages! And in kitchen science we find out which surface is best for keeping ice cool.

But why are they suffering and what can we do to stem the problem....

Fastest Melting Ice

Does the speed of ice melting depend on what surface it's on? We compare an ice cube on a frying pan to an ice cube on a chopping board...
