We may be starting to get a grasp on what kick-started life on Earth – and it could help us search for it on other planets

A newly discovered mechanism could explain the shock finding last year that oxygen is produced by metallic nodules on the seafloor – and it might be happening on other planets, too

A study of the fossilised fur of six mammals from the Jurassic and Cretaceous periods has found they were all greyish-brown in colour, which would have helped them hide from dinosaurs

Some male octopuses tend to get eaten by their sexual partners, but male blue-lined octopuses avoid this fate with help from one of nature’s most potent venoms

How sexual reproduction came about has long been a mystery, but an evolutionary model suggests it could have started with cells fusing to increase their food reserves

Coots' nests in Amsterdam are built using discarded plastic, providing a time capsule into the material's use over the past few decades

When competition for food is high, both chimps and bonobos sometimes rub their genitals together to cope
