Advanced magnetic resonance imaging (MRI) technology can detect heart attack in emergency room patients with chest pain more accurately and faster than traditional methods, according to a new study supported by the National Heart, Lung, and Blood Institute (NHLBI). Published in the February 4 issue of Circulation: Journal of the American Heart Association, the findings suggest that more patients who are suffering a heart attack or who otherwise have severe blockages in their coronary arteries could r

A Penn State researcher has developed a faster method for more efficient sharing of widely distributed Internet resources such as Web services, databases and high performance computers.

Jonghun Park, assistant professor in Penn State’s School of Information Sciences and Technology (IST) who has proposed the protocol, says the new technology speeds up to 10 times faster the allocation of Internet resources.

“In the near future, the demand for collaborative Internet applications wi

White tea extract reveals anti-cancer, anti-aging properties

Scientists at University Hospitals of Cleveland and Case Western Reserve University have proven that ingredients in white tea are effective in boosting the immune function of skin cells and protecting them against the damaging effects of the sun. The discovery that white tea extract protects the skin from oxidative stress and immune cell damage adds another important element in the battle against skin cancer.

Biochemical mechanism may lead to new cancer prevention and treatment strategies

Scientists at St. Jude Children’s Research Hospital have discovered a novel biochemical process that plays a critical role in helping cells in the body respond to DNA damage, such as that caused by exposure to radiation, environmental toxins or free radicals.
The findings could lead to new approaches to prevent cancer, better ways to treat cancer and to the development of sensitive methods deter

Researchers at Washington University School of Medicine in St. Louis have found that immune cells called B cells and the antibodies they produce play a critical early role in defending the body against West Nile Virus. The results are published in the February issue of the Journal of Virology.

Mice that lacked B cells and antibodies were completely unable to combat the virus. They developed serious brain and spinal-cord infection and ultimately died.

“These findings may help expla

Scientists have long touted carbon nanotubes as a futuristic means of delivering drugs, fortifying brittle materials and conducting current in miniaturized circuits. But attempts to introduce actual nanotubes into these roles have often been stopped in their tracks by the slender filaments’ stubborn and unhelpful tendency to clump together in solution.

Now scientists at the University of Pennsylvania have found that a readily available chemical, a surfactant called sodium dodecylbenzen
