Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism by which brain cells die. The findings raise the possibility that similar ...

Your fate can be determined by tiny events. Imagine you live in the city and you walk everywhere to get exercise – you are healthy and not afraid of getting mugged. You almost never eat breakfast so ...

Scientists have traced a devastating pattern of brain cell loss in a handful of families to a single, ultra-rare mutation ...

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 ...
