    High-altitude help from extinct ancestors

    The Tibetan plateau is high in altitude but low in oxygen. An unusual version of one gene in Tibetans' DNA helps them survive this environment. And that gene appears to have been passed along from Denisovans, a Neandertal-like ancestor.

    Newfound DNA ‘enhancer’ behind many natural blonds

    Some snippets of DNA other than genes play a role in giving some people of European a golden crown of hair.

    A success for designer life

    Synthetic biologists are scientists who create custom organisms in the lab. Their efforts have just taken a big step forward. They have created the first lab-made yeast chromosome. The advance could lead to entirely synthetic organisms customized to produce food, fuel or medicine.

    Ancient DNA sparks new mystery

    DNA from a 400,000-year-old leg bone found in Spain is by far the oldest recovered from pre-human ancestors. It also shows an unexpected link to later, Asian ‘kin.’
