The evolutionary mystery of menopause is a step closer to being solved thanks to research on killer whales.

Scientists in Cambridge have found cracks in the long-standing theory that the number of eggs animals have - and the size of those eggs - is related to how much parental care they invest in their offspring.

Tropical fish alter their behaviour with an eye to the future, researchers at Cambridge have found. This is the first time such behaviour has been seen in any animals except humans.

One of the most devastating events in the insect world - the locust swarm - has extraordinary effects on the insect's brains, scientists in Cambridge have discovered.

Using field experiments in Africa and a new computer model that gives them a bird's eye view of the world, Cambridge scientists have discovered how a bird decides whether or not a cuckoo has laid an egg in its nest.

Mother birds communicate with their developing chicks before they even hatch by leaving them messages in the egg, new research by a team from the Department of Zoology, University of Cambridge, has found.

How two butterfly species have evolved exactly the same striking wing colour and pattern has intrigued biologists since Darwin's day. Now, scientists at Cambridge have found "hotspots" in the butterflies' genes that they believe will explain one of the most extraordinary examples of mimicry in the natural world.

The commonly held assumption that as primates evolved, their brains always tended to get bigger has been challenged by a team of scientists at Cambridge and Durham.

Pipes blocked by an invasion of freshwater mussels pose a severe problem to the water industry. A tiny, fat-coated capsule could provide the answer.

Scientists have shown for the first time that insects, like mammals, use vision rather than touch to find footholds. They made the discovery thanks to high-speed video cameras - technology the BBC uses to capture its stunning wildlife footage - which they used to film desert locusts stepping along the rungs of a miniature ladder.
