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

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health ...

The Collaborative Cross (CC) mouse resource has emerged as an indispensable platform for elucidating the genetic basis of complex traits. By combining high levels of genetic diversity from eight ...

David Rand, a professor of natural history at Brown University, explains how studying mitochondria — the cell's energy producers — offers a useful way to understand complex gene-by-gene or ...

What makes every person unique? Part of the answer is in our genes. A gene is a basic unit of heredity, the means by which traits get passed from one generation to the next, and genetics is the study ...

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

Northwestern University biophysicists have developed a new computational tool for identifying the gene combinations underlying complex illnesses like diabetes, cancer and asthma. Unlike single-gene ...

A growing body of genetic evidence suggests that Neanderthals and Denisovans carried many of the same regulatory gene networks linked to language and vocal anatomy in modern humans, challenging the ...

Ancient microbes tied to our earliest ancestors could use oxygen, reshaping ideas about how complex life began on Earth.

Genes may play a bigger role in living a longer life, while lifestyle and luck still shape the outcome, according to a new ...
