How researchers have pinpointed the origin of 'warm-blooded' mammals
The evolution of ‘warm bloodedness’ allowed mammals to live in a more diverse range of habitats, but working out when this occurred has been difficult. To try and pin down a date, researchers have studied the fossilised remains of ancient mammals' inner ears, which suggest that this key evolutionary leap appeared around 230 million years ago.

09:47 Structure of an enzyme reveals how its so efficient
Hydrogen dependent CO2 reductase is an enzyme that can convert CO2 from the air into formic acid that can be used as fuel. It also does this extremely efficiently, but nobody has been quite sure how. Now researchers have an idea based on a detailed structural analysis.
