Hormone-unrelated breast cancer death rate lowered by reducing dietary fat
Medical News Today
Reducing dietary fat intake for at least five years after diagnosis could help improve survival rates for early stage breast cancer patients with hormone-unrelated breast cancer, according to a new study. The findings of the study were presented at the 2014 San Antonio Breast Cancer Symposium — a five-day conference aiming to provide state-of-the-art information on breast cancer research to an audience of researchers and physicians from over 90 countries.More

Researchers discover new class of stem cells
Los Angeles Times
Researchers have identified a new class of lab-engineered stem cells — cells capable of transforming into nearly all forms of tissue — and have dubbed them F-class cells because they cluster together in "fuzzy-looking" colonies. The discovery, which was described in a series of five papers published in the journals Nature and Nature Communications, sheds new light on the process of cell reprogramming and may point the way to more efficient methods of creating stem cells, researchers say.More

Cheap, disposable biometric patch to monitor stress and fatigue in military personnel may be adapted to monitor biomarkers used by clinical pathology laboratories
DARK Daily
One potential disruptor of medical laboratory testing, as it exists today, are wearable biometric devices. These are already popular with athletes and health-conscious people. To meet this demand, a continual stream of innovative biometric gear is hitting the marketplace. More

'Genome editing' could correct genetic mutations for future generations
Indiana University via ScienceDaily
A technique for "editing" the genome in sperm-producing adult stem cells has been demonstrated by researchers, a result with powerful potential for basic research and for gene therapy. The study involved spermatogonial stem cells, which are the foundation for the production of sperm and are the only adult stem cells that contribute genetic information to the next generation. More

Hepatitis C ruled out as cause of mental impairment in HIV patients
Washington University in St. Louis via Infection Control Today
Advances in treatment for human immunodeficiency virus have made it possible for people with HIV to survive much longer. As they age, however, many experience impaired thinking, memory loss, mood swings and other evidence of impaired mental function. To stop these changes, scientists have to learn what is causing them.

Ebola vaccine trial halted temporarily after joint pains
Reuters
A clinical trial of an Ebola vaccine developed by Merck and NewLink has been halted temporarily as a precautionary measure after four patients complained of joint pains, the University of Geneva Hospital said. "They are all fine and being monitored regularly by the medical team leading the study," it said in a statement.More

Scientists often skip a simple test that could verify their work
WBUR-FM
VideoBriefThere's a simple test that scientists could use to make sure the cells they're studying in the lab are what they think they are. But most of the time, academic scientists don't bother. That omission is a problem. One study found that between 18 percent and 36 percent of all cell lines have been misidentified. More

Study: No link between migraine, breast cancer risk
HealthDay News
A large, new study should reassure the millions of American women who have migraine: The debilitating headaches don't raise the risk for breast cancer. "There is no association between migraine and breast cancer risk," said lead researcher Rulla Tamimi, an associate professor of medicine at Harvard Medical School.More

Ebola virus may replicate in an exotic way
Lab Manager
University of Utah researchers ran biochemical analysis and computer simulations of a livestock virus to discover a likely and exotic mechanism to explain the replication of related viruses such as Ebola, measles and rabies. The mechanism may be a possible target for new treatments within a decade.More

Scientists reprogram fat cells to burn off calories
Medical News Today
Scientists have discovered the genetic mechanism through which calorie-storing white fat cells can be reprogrammed to become more like calorie-burning brown fat cells. The finding could lead to new drugs that target the mechanism to help treat obesity.More
