The last common ancestor of all living things did not just suddenly appear on Earth roughly 4.2 billion years ago. Some of ...

What do your genes have to do with growing old? Quite a lot. But is it due to the actual DNA, or the way those genes are expressed? KPBS sci-tech reporter Thomas Fudge has more on new research that ...

What determines how long we live—and to what extent is our lifespan shaped by our genes? Surprisingly, for decades, scientists believed that the heritability of human lifespan was relatively low ...

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

The length of your life may depend more upon your genes than scientists thought. Once you remove from consideration events that cut life short — such as infections and injury — genetics account for ...

Scientists have created the most detailed maps yet of how genes control one another inside the brains of people with Alzheimer’s disease. Using a powerful new AI-based system called SIGNET, the team ...
