Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism by which brain cells die. A team led by scientists at the German research ...

Scientists have traced a devastating pattern of brain cell loss in a handful of families to a single, ultra-rare mutation that sabotages one of the brain’s key protective enzymes. The discovery not ...

A new study has found a rare genetic mutation that allows some of us to get only a few short hours of sleep and wake up feeling fully rested and wide awake.

Mayo Clinic researchers have identified a rare mutation in the MET gene that can directly cause metabolic dysfunction-associated steatotic liver disease. The mutation disrupts the liver’s ability to ...

In our earliest science lessons, we learned that anything denser than water sinks. The denser something is, the more easily it sinks. This is seen in people who are more muscular, because muscle is ...
