Single mutation brought many East Asian traits

A single mutation around 30,000 years ago appears to be responsible for several traits common in East Asian peoples, from thicker hair to denser sweat glands.

Genetic mutation explains human migration

The reason you (probably - let's not make assumptions here) don't live by an African lake and feed mainly on fish may be a single, ancient mutation.

Avian flu could easily become pandemic

The second of two highly-controversial academic papers on the H5N1 avian influenza has now been published, showing the virus is just four mutations away from an airborne version that could pass from human to human.

Trouble brewing for GM crops

Pests are adapting to genetically modified plants designed to kill them, raising doubts over the future of biotech crops.

Vicious new strain of avian flu created in lab

Dutch researchers have created a virus in the lab that could wipe out half the human race.

Researchers breed mice that sing

Japanese researchers say they've created a mouse that sings like a bird. They say the development could shed light on the evolution of human language - and, they suggest, lead to the creation of a talking mouse.

Tibetans evolved quickly to deal with altitude

Tibetans' adaptation to high altitude took place over less than 3,000 years, a new genetic analysis shows, in what was the fastest shift in human evolution yet discovered.
