A single gene controls movement in vertebrates

Scientists have found that one gene is responsible for variability in locomotion in horses and mice.

It is usually the male mice who do the singing. Photo courtesy of Bret Pasch.

Why do women live longer than men?

Aussie women have an average lifespan of 84 years, while the men have an average of 80. The reason why could lie in our genes.

Climate change and the modern polar bear

Polar bear evolution holds clues for past climate change events.

Mapping our microbes

They may be small, but they outnumber our cells.

Breeding for appearance may lead to a sacrifice in flavour.

Niceness may be predicted by our genes

  DNA may help explain why some people are nicer than others.
