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.

WASHINGTON — Two-thirds of animal and plant populations are declining in genetic diversity, which makes it harder to adapt to environmental changes, according to research published Wednesday.

Genetic changes in a population over time are influenced by a range of factors, such as mutations, natural selection, genetic drift, gene flow, and sexual selection. Mutations introduce new genetic ...

Since the immune reaction to abacavir could be traced to a single variation, in a single gene, with a clear link to patient outcomes, the genetic test could easily help avoid the drug’s side effects, ...
