Ancient-DNA analysis has confirmed that two children buried together in Anglo-Saxon England 1,400 years ago were siblings, lending rare biological detail to an unusually intimate grave

A fresh critique of a foundational idea in human genetics argues that population structure in ancient Homo sapiens may explain key DNA patterns without requiring the standard interbreeding narrative.

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 say new genetic causes of diabetes in babies have been found in non-coding regions of the genome that older studies often overlooked.

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.

A study announced by the 23andMe Research Institute identified genetic predictors tied to both GLP-1 weight-loss efficacy and side effects, highlighting a possible path toward more personalized obesity treatment.

Researchers have used large-scale mapping of genetic variants in a single gene to clarify which changes are disease-causing and to identify a new neurodevelopmental condition.

A 900,000-person study published in Nature reveals how age, sex, season, smoking, and genetics shape the viral loads of seven DNA viruses that persist in the human body across a lifetime.

DNA extracted from a 12,000-year-old double burial in southern Italy has revealed that a mother and daughter both carried mutations causing a rare skeletal growth disorder. The discovery marks the earliest genetic diagnosis of its kind and offers a window into prehistoric community care.
