Koalas’ population comeback may be doing more than boosting numbers—it could also be rebuilding their lost genetic diversity.

As koalas in southern Australia have grown from a few hundred to almost half a million, the marsupials show signs of regaining lost genetic variation.

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 ...

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 ...

Fish caught in the same trawl and sold under the same name may in fact have significant genetic differences. Beneath the surface of the Skagerrak lies a biological diversity that is rarely seen in ...

Humans are still evolving, and Tatum Simonson, PhD, founder and co-director of the Center for Physiological Genomics of Low Oxygen at University of California School of Medicine, plans to use ...

A new study finds the genetic backgrounds of people in the U.S. are "highly complex" and may differ from their self-defined racial or ethnic groups.

The daily rotation of Earth and its yearly voyage around the Sun marks the natural rhythm of life on the planet. Human health indicators such as body temperature, blood pressure and sleep, as well as ...
