Gene drive seeks to insert or remove a chosen trait in the genome of an entire species. Future applications include eliminating malaria, the zika virus and other diseases.

Dinosaurs Alive is an exhibit consisting of large, animatronic animals. This article contains photos of some of the models and facts about the real animals.

Hair color is primarily genetic, and red hair is caused by mutations in the MC1R gene. The gene for red hair also causes an increased sensitivity to sunlight and a reduced sensitivity to anesthesia. Contrary to internet rumors, redheads are not going extinct! Famous redheads include Queen Elizabeth I and Malcolm X.

The discovery of a single tooth led to the belief in an ape-like creature had once roamed the plains of the New World.

Examining what it means to have Irish blood, outlining where Irish DNA comes from and who are the closest genetic relatives of the Irish in Europe. Of interest to anyone with Irish ancestry who wants to understand their genealogy.

This hub outlines the process of protein synthesis within a eukaryotic cell.
