A single microscopic change in our DNA can permanently alter how the brain is built, locking in developmental problems that ...

A vanishingly rare genetic glitch in a single enzyme can erase a newborn’s brain cells in a matter of weeks, leaving doctors ...

Traditional biochemical methods of studying human gene mutations are often laborious and costly. Now bioengineers at the University of California San Diego have developed a new simple approach to ...

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

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 ...

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose -- and how it protected our ancestors from ancient diseases. Modern HIV ...

A genetic mutation found in two human patients with schizophrenia also increased schizophrenia-related behaviors in mice with the same mutation, a rare finding of a direct genetic link to psychosis, ...

A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...

Now, researchers have identified one of these mutations, named SIK3-N783Y, in a human super-sleeper. The team then studied the mutation in genetically modified mice and found that the mice carrying ...

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 ...
