Ebola can survive in victims' bodies for days
Medical News Today
After testing swabs and tissue samples from the bodies of deceased Ebola-infected monkeys, scientists determined the virus can stay alive for up to seven days in a dead victim. They also found that noninfectious viral genetic material can remain for up to 70 days after death.More

Growing wave of hospital and health system megamergers means changing dynamics for pathology and clinical laboratory medicine
DARK Daily
Large and financially stable multihospital health systems are racing to form regional megasystems. It's a strategy to get ahead of the Affordable Care Act's mandate to improve quality and increase efficiency through coordinated care across the entire care continuum. This growing national trend means further consolidation of clinical laboratory testing services within the merging organizations. More

Study: Cancer patients rarely request unneeded tests, treatments
HealthDay News
Despite some doctors' claims to the contrary, cancer patients rarely request unnecessary tests or treatments, a new study finds. Researchers surveyed 34 oncologists, 11 oncology fellows and 15 nurse practitioners immediately after visits with cancer patients at three Philadelphia hospitals between October 2013 and June 2014.More

Promising results for new Alzheimer's therapy
Karolinska Institutet via ScienceDaily
Scientists have evaluated a new Alzheimer's therapy in which the patients receive an implant that stimulates the growth of a certain type of nerve cell. The results suggest that the introduction of a nerve growth factor can prevent neuronal degradation in Alzheimer's patients.More

Novel image-analysis technique improves breast cancer detection and diagnosis
University of Oklahoma College of Engineering via
Researchers at the University of Oklahoma have developed an image-analysis technique that is designed to improve breast cancer detection and diagnosis. Bin Zheng and his research team have developed image processing algorithms to generate quantitative image markers by analyzing multiple digital X-ray images and building statistical data learning-based prediction models.

Key to blocking influenza virus may lie in a cell's own machinery
Rockefeller University via Infection Control Today
Viruses are masters of outsourcing, entrusting their fundamental function — reproduction — to the host cells they infect. But it turns out this highly economical approach also creates vulnerability. Researchers at Rockefeller University and their collaborators have found an unexpected way the immune system exploits the flu virus' dependence on its host's machinery to create new viruses capable of spreading infection.More

IVF embryos: Whole genetic code can be scanned for mutations
Medical News Today
Genetic scientists have used a new technique that allows the whole genome of in vitro fertilization embryos to be scanned via the cells of 10 biopsies. The researchers say the testing is the first to be able to detect all the new genetic mutations that happen uniquely in an individual, as opposed to only those that have been handed down from parents.More

Researchers find new mechanism that controls immune responses
Health Canal
UT Southwestern Medical Center researchers have identified a common signaling mechanism to produce interferon — one of the main proteins used to signal the immune system when the body needs to defend itself against a virus, tumor or other diseases. The findings are important for understanding the body's immune defense system, searching for compounds to turn the immune system on or off, and they may help combat autoimmune diseases, in which overactive immune cells attack healthy tissues.More
