A study expands the list of known genes with circadian variation and provides the first comprehensive list of genes with seasonal variation in each tissue. Tissues in the thoracic cavity, such as the ...

image: New research finds there is significant variation in the anatomy of the human digestive system, with pronounced differences possible between healthy individuals. The finding has implications ...

Researchers have mapped variation in human stem cells that explains how cells of an individual may shape a unique 'developmental dance' at the molecular level, thereby controlling how the brain and ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

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 ...

The human body is an exquisite formation that structures our movements, abilities, and identities. Careful observation, description and analysis of human anatomy can inform an understanding of the ...

A groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from two ancient and distinct groups. This research, published in March 2025, ...
