Rapidly testing hundreds of thousands of DNA sequences, scientists identified specific genetic variations contributing to blood pressure, cholesterol, and blood sugar.

Horses have played a critical role in shaping human society, but scientists are still piecing together the story of their domestication. Reading time 3 minutes Roughly 4,500 years ago, humans forged a ...

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 ...

Scientist He Jiankui will likely go down in history as the first human to genetically engineer another living person. He has now been fired. Thanks to his unethical behavior, genetic engineering ...

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 modification of the genetic makeup of cells. Genetic engineering modifies the DNA in cells to alter their behavior. In 1953, the discovery of the DNA double helix, technically deoxyribonucleic ...
