Researchers have identified four more Franklin expedition sailors using genetic matches with living descendants, adding new detail to one of Arctic exploration’s best-known disasters.

Researchers found that altering one DNA base in female mouse embryos was enough to trigger development of male reproductive organs, highlighting the outsized effects tiny genomic changes can have during development.

Researchers at Bar-Ilan University report that changing a single DNA letter can completely alter sex development in mice, underscoring how small genetic changes can have outsized biological effects.

Researchers analyzing a medieval burial in a much older Stone Age monument in Spain have identified the man’s genetic ancestry, while his religious identity remains unresolved.

A new preprint finds a highly mixed DNA record on the Shroud of Turin, complicating attempts to use genetics to pin down the relic’s age or origin.

Scientists analyzing material returned by Japan's Hayabusa2 from asteroid Ryugu have confirmed all five nucleobases that form the chemical alphabet of DNA and RNA, the strongest evidence yet for space-based origins of life's chemistry.
