Biology has clever ways to mask the effects of potentially harmful gene mutations. Scientists are investigating how this ...

In simple terms: a mutation is a stable change in genetic sequence that can be copied when cells or viruses replicate. Most mutations have no detectable effect, some contribute to disease, and a small ...

Each year, roughly the same numbers of boys and girls are born. But in individual families, some couples have four or more daughters and no sons, and some have all male children and no female children ...

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. What do a ...

Researchers have developed a new framework to study the functional impact of genetic background on the expression and severity of neurodevelopmental features associated with a deletion of a portion of ...

The root causes of most forms of Alzheimer's disease largely remain a mystery. Now, researchers have revealed a new piece of the puzzle. Neurogeneticists at the University of Florida led by Lien ...

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 ...

Every person on Earth with blue eyes can trace that trait back to a single genetic change in one individual who lived ...

Geneticists argue that every blue-eyed person alive today may be connected by a single ancient DNA change that dimmed pigment ...

Florida panthers are making a comeback. That's the conclusion a team including UCLA biologists has come to following an attempt at a genetic rescue for the cat that began 30 years ago. In the 1990s, ...

Researchers have detected a human genetic variant that influences the sex ratio of children. Additionally, they found that many hidden genetic variants of sex ratio may exist in human populations.
