Ultra-low oxygen could have triggered die-offs, spurred bird breathing system
A University of Washington scientist is theorizing that low oxygen and repeated short but substantial temperature increases because of greenhouse warming sparked two major mass-extinction events, one of which eradicated 90 percent of all species on Earth.

Proof that PUMA stalks cancer cells solves long-standing mystery of the anti-cancer role of p53
A team of scientists led by investigators at St. Jude Children's Research Hospital has demonstrated that the p53 gene, long considered to be a central conductor of the process by which abnormal cells self-destruct, actually relies on the PUMA gene to trigger that activity.

Signals from space enable earthquake detection
A violent earthquake that cracked highways in Alaska set the sky shaking as well as the land, an ESA-backed study has confirmed.

Scientists identify novel enzyme with key role in leukemia protein's normal function
