A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Researchers at the Francis Crick Institute have identified genetic changes in blood stem cells from frequent blood donors that support the production of new, non-cancerous cells. Understanding the ...

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 ...

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 ...

Tail loss in gorillas, chimpanzees, and humans is believed to have occurred about 25 million years ago, when the group evolved away from Old World monkeys. A genetic change in our ancient ancestors ...

A genetic analysis of polar bears in southeast Greenland found that genes related to heat-stress, aging, and metabolism are ...

Researchers have uncovered that some childhood cancers have a substantially higher number of DNA changes than previously thought, changing the way we view children’s tumours and possibly opening up ...

Blood donation is an important way to support community health. A consistent, reliable and safe blood supply is necessary for providing proper healthcare to trauma victims, surgical support, and other ...

A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...

Genetic testing for chronic myeloid leukemia (CML) can tell doctors if someone has leukemia, what type they may have, and whether treatment is working. The tests look for atypical changes in certain ...

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 ...
