Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health traits. By probing regions of DNA previously linked to disease, the work has ...

The study, published in Nature, examined 74 quantitative traits, including cholesterol, blood glucose, hemoglobin, heart rate ...

Genetic engineering is moving from the lab bench into clinics, farms, and even family planning decisions, promising to change how we prevent disease, age, and define human potential. The same tools ...
