Companies may still buy consumer genetic information despite its modest predictive power
Genetics can be associated with one's behavior and health—from the willingness to take risks, and how long one stays in school, to chances of developing Alzheimer's disease and breast cancer. Although our fate is surely ...

Researcher discusses mechanism behind a birth defect affecting brain size
Nonsense-mediated RNA decay, or NMD, is an evolutionarily conserved molecular mechanism in which potentially defective messenger RNAs, or mRNAs (genetic material that instructs the body on how to make proteins), are degraded. ...
