Researchers design potential blood thinner that also unmasks cancer cells

Posted: 06 Dec 2012 09:46 AM PST

Virginia Tech researchers have discovered a potential way to create a new kind of anticoagulant drug commonly called a blood thinner.

Blood thinners are important for people with high blood pressure or who are at risk for heart attacks and strokes — leading causes of death in the United States.

Researchers discover regulator linking exercise to bigger, stronger muscles

Posted: 06 Dec 2012 09:39 AM PST

Scientists at Dana-Farber Cancer Institute have isolated a previously unknown protein in muscles that spurs their growth and increased power following resistance exercise. They suggest that artificially raising the protein's levels might someday help prevent muscle loss caused by cancer, prolonged inactivity in hospital patients, and aging.

Surgeons Implant First Brain ‘Pacemaker’ for Alzheimer’s Disease in United States as Part of a Clinical Trial Designed to Slow Memory Loss

Researchers at Johns Hopkins Medicine in November surgically implanted a pacemaker-like device into the brain of a patient in the early stages of Alzheimer’s disease, the first such operation in the United States. The device, which provides deep brain stimulation and has been used in thousands of people with Parkinson’s disease, is seen as a possible means of boosting memory and reversing cognitive decline.

Bilirubin Can Prevent Damage from Cardiovascular Disease

Each year, about 610,000 Americans suffer their first heart attack, according to the Centers for Disease Control and Prevention. Heart attacks and other symptoms of cardiovascular disease can be caused when blockage occurs in the arteries. In a new study from the University of Missouri, a scientist has discovered a natural defense against arterial blockage: bilirubin.

FERMI Improves its Vision for Thunderstorm Gamma-Ray Flashes

Thanks to improved data analysis techniques and a new operating mode, the Gamma-ray Burst Monitor (GBM) aboard NASA's Fermi Gamma-ray Space Telescope is now 10 times better at catching the brief outbursts of high-energy light mysteriously produced above thunderstorms.
