Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism ...

Three start-ups are aiming to create gene-edited babies. Columnist Michael Le Page has no doubt that editing our offspring ...

Ever looked in the mirror and wondered why you’ve got those tiny cheek holes or why you can see colors your friends can’t? It ...

During development of the digestive system, a complex network of nerves forms around it, creating a "second brain"—the enteric nervous system (ENS)—which controls the movement of food and waste ...

A microscopic flaw in the brain’s cellular scaffolding can shape brain size for life.

Gene editing has moved from theory to bedside with a speed that would have seemed impossible a decade ago. A new wave of ...

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 ...

Even as humpbacks rebound in number, their genomes reveal a loss of genetic diversity and a buildup of harmful mutations left ...

This study offers important insight into the pathogenic basis of intragenic frameshift deletions in the carboxy-terminal domain of MECP2, which account for some Rett syndrome cases, yet similar ...

“A blessing and a curse” is how Harry Aikines-Aryeetey describes the genetic quirk that means his body carries more muscle ...

A new CRISPR approach can control genes without cutting DNA, opening a safer path for treating genetic diseases. A newly ...

Scientists discovered that the first 100 base pairs of human genes are unusually prone to mutations, especially during the earliest stages of embryonic development. These mosaic mutations often go ...
