This figure shows primary T cells modified using two approaches. CAR receptors are introduced through targeted DNA insertion (top), while CRISPRoff mRNA and guide RNAs silence additional genes through ...

Scientists discovered that aging DNA repeats expand at wildly different speeds—and in some people, the consequences can be devastating. A sweeping genetic study drawing on data from more than 900,000 ...

The basic outline of the interactions between modern humans and Neanderthals is now well established. The two came in contact as modern humans began their major expansion out of Africa, which occurred ...

Putting the uniquely human version of a certain gene into mice changed the way that those animals vocalized to each other, suggesting that this gene may play a role in speech and language. Mice make a ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Modern humans descended from ...

Humans were isolated in southern Africa for about 100,000 years, which caused them to "fall outside the range of genetic variation" seen in modern-day people, a new genetic study reveals. The finding ...
