Some lucky people have rare genetic mutations that enable them to feel well-rested after just four hours of sleep, while the rest of us need around eight hours to function. Now, researchers have ...

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 ...

A vanishingly rare genetic glitch in a single enzyme can erase a newborn’s brain cells in a matter of weeks, leaving doctors with almost no way to intervene. Researchers have now traced that ...

Researchers identified a new genetic mutation that may allow some people to survive, even thrive, on three hours of sleep. The mutation is called SIK3-N783Y. Scientists said mice test subjects ...

Meet the luckiest people on Earth — individuals carrying a rare genetic mutation that prevents wrinkles from forming even as they age well into their 80s. These genetic lottery winners have provided ...

The sperm of a man carrying a rare genetic mutation linked to cancer was used to conceive scores of children across Europe, prompting calls for greater regulation and a limit on the number of births ...

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 ...
