The mechanics behind how an important process within the cell traps material before recycling it has puzzled scientists for years. But Penn State researchers have gained new insight into how this process seals off waste, much like a trash bag. The process, called autophagy, allows cell waste and damaged material in the cell to be recycled into energy or new […]

Do your knees ache? According to new findings from the Oklahoma Medical Research Foundation, your diet could be a culprit. In a study led by OMRF scientist Tim Griffin, Ph.D., researchers found that the carbohydrate composition of diets increased the risk of osteoarthritis in laboratory mice—even when the animals didn’t differ in weight. “We know increased body fat elevates risk, […]

(HealthDay)—The first new tick species to appear in the United States in 50 years is spreading rapidly in the east and has been confirmed in seven states and the suburbs of New York City. In its home range, the Asian longhorned tick (Haemaphysalis longicornis) carries a virus that kills 15 percent of its victims, but is considered a greater threat […]

According to the US Center for Disease Control, the number of worldwide cases of poliomyelitis has decreased from 350,000 in 1988 to 407 in 2013. While the decline has been steady, polio has still not been eradicated. To try and help solve the problem, biologists and mathematicians from IBM, UCSF, Stanford University, and the University of Haifa are working side-by-side […]

A City of Hope researcher has developed a stem cell model to assess possible treatments for a rare nervous system disorder that is in the same disease group as Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis (ALS). The finding takes Yanhong Shi, Ph.D., senior author of the study, and her colleagues one step closer to finding a way to […]

The World Health Organization said Friday it hopes to know as early as Tuesday whether the strain of Ebola in Congo’s latest outbreak of the deadly virus is the one for which an experimental vaccine can be used. The global agency’s emergencies director said 3,000 vaccine doses are still in Congo’s capital after being positioned there for an earlier outbreak […]

Research led by Rinku Majumder, Ph.D., Associate Professor of Biochemistry at LSU Health New Orleans School of Medicine, has found how hypoxia (a low concentration of oxygen) decreases Protein S, a natural anticoagulant, resulting in an increased risk for the development of potentially life-threatening blood clots (thrombosis). Although hypoxia has been associated with an increased risk for thrombosis, this research […]

The International Federation of Red Cross and Red Crescent Societies says the response to the new Ebola virus outbreak in Congo’s North Kivu province will be “highly complex” given the armed unrest in the region. Dr. Fatoumata Nafo-Traore, regional director for Africa, says the proximity to a city of more than 230,000 people and an international border also complicates the […]

After 10 years of research, a Rutgers-led team of scientists has identified two molecules that protect nerve cells after a traumatic brain injury and could lead to new drug treatments. The molecules promote full recovery after traumatic brain injury (TBI) in mice, according to the study published online in Neurobiology of Disease. Traumatic brain injury is the leading cause of […]

Research conducted at the Wayne State University School of Medicine has helped confirm the effectiveness of a blood biomarker that can indicate if patients with a head injury can avoid a costly CT scan because the blood test results indicate no traumatic brain injury (TBI). The findings, published online in The Lancet Neurology on July 24, validated the use of […]
