Scientists have achieved a genetic feat once thought impossible: removing an entire extra human chromosome using gene-editing ...

In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...

Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

A new study suggests that those with long-lived families probably have the best prospects of making it to a very old age.

Scientists have long believed that longevity is shaped by lifestyle choices; however, a new study reveals that genes may play a larger role in determining how long people live.

Many factors influence how long you live, such as diet, exercise, smoking, drinking, environment and other variables. It also ...

A person’s genes play a far greater role in likely lifespan than previously thought, according to a major new study published ...

A large study published Jan. 29 in the journal Science suggests genetics could account for as much as 55% of a person’s lifespan. That’s far higher than earlier estimates, which ranged from 6% to 33%.

Testing the biological sex of an athlete is becoming more common in sport, with governing bodies defending the practice as ...
