For years, scientists believed our lifespan was mostly shaped by environment and chance, with genetics playing only a minor role. But a new study from the Weizmann Institute flips that idea on its ...

For decades, scientists have debated how much of our lifespan is written into our DNA and how much is shaped by the world around us. New research is tilting that balance toward biology, suggesting ...

A gene-edited mouse created with two male parents has now survived to reach adulthood. This is a momentous occasion for genetics, as previous attempts to create bi-paternal mice have failed for a ...

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 ...

A husband-and-wife team whose love story began in a Harvard anatomy lab have won one of science’s biggest awards for creating ...

The physical differences between men and women are all too obvious, but the biological divide goes right down to the cellular ...

Researchers have discovered genes linked to obesity in both Labradors and humans. They say the effects can be over-ridden with a strict diet and exercise regime. Researchers studying British Labrador ...

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 ...

A new study in Molecular Psychiatry looked at the DNA of 131,895 people and asked two simple questions. Have you ever used cannabis? If yes, how often? Among those who had tried, frequency was ...

Scientists used precise gene-editing to grow larger African eggplants. Credit: Zachary Lippman, Cold Spring Harbor Laboratory Tomatoes come in all kinds of colors, sizes, and flavors. But what’s going ...

NEW YORK (AP) — Neanderthals and humans likely mixed and mingled during a narrow time frame 45,000 years ago, scientists reported Thursday. Researchers analyzed ancient genes to pinpoint the time ...
