No gene acts alone: interacting variants and protein partnerships can worsen, mask or even rescue disease risk, demanding ...

Polar bears are leaping through their evolution in real time as rising temperatures threaten their habitat. A population of bears was found in a climate warmer than one in which they usually exist and ...

The world’s polar bear population is projected to decline by two-thirds by 2050. A new study from the University of East Anglia suggests that polar bears are undergoing rapid genetic changes, and ...

With climate change steadily dismantling the icy habitat essential to their existence, new research suggests polar bears are rapidly rewiring their own genetics in a bid to survive. The species is ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Changes in genes have been linked to the development of different diseases for a while. However, it's not exactly clear what ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.
