Ancient humans crossing the Bering Strait into the Americas carried more than tools and determination—they also carried a genetic legacy from Denisovans, an extinct human relative. A new study reveals ...

An ad hoc committee appointed by the National Academies to explore heritable genetic modifications of food animals. This committee will address methods for heritable genetic modifications and identify ...

Investigators affiliated with VIB and UGent recently achieved great success with a study involving biomedical research on mouse models. The research group of Prof Peter Vandenabeele (VIB/UGent) ...

Almost 100 years ago, Carrie Buck was raped, labeled an “imbecile,” and sterilized by order of the state — all in the name of genetic progress. Today, we no longer use that word, but the dream of ...

Understanding how genes influence complex behaviors remains one of biology's most fascinating challenges. Now, however, in a recent study, researchers have compiled a comprehensive dataset documenting ...

Genetic defects are exceedingly common, which is not surprising considering just how many cells make up our bodies, including our reproductive cells. While most of these defects have no or only minor ...

When did the first humans start speaking? Did we always have this ability, inherited from our immediate ancestors? These questions sound impossible to answer — but not quite so. A new study, drawing ...
