Most people alive today carry fragments of Neanderthal DNA in their genome. Now scientists are gaining a more intimate understanding of the ancient encounters that put it there. By Carl Zimmer One of ...

Investigators are analyzing DNA evidence from the home of missing 84-year-old Nancy Guthrie. Previous DNA testing on gloves found two miles away did not produce a match in the FBI's national database.

Although DNA evidence collected in the Nancy Guthrie investigation has yet to yield matches, law enforcement is still bracing for results that could expose cracks in the southern Arizona case ...

DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this ...
