Arlington Police solved a 1985 murder case using DNA and genetic genealogy, identifying Bernard Sharp as the perpetrator posthumously.

The ability to extract trace bits of DNA from soil, water, and even air is revolutionizing science. But it's not foolproof. In the late 1980s, at a federal research facility in Pensacola, Florida, Tamar Barkay used mud in a way that proved revolutionary in ...

Researchers set a new world record for the fastest DNA sequencing, completing a whole genome in under four hours—a breakthrough with potential for faster, targeted care.

A switch to a new technology made DNA analysis more accurate at the Bexar County Criminal Investigation Lab, but it also takes longer. That is prompting a larger backlog of cases. The lab is now responding in multiple ways.
