The number of total hip replacements (THRs) nearly doubled among middle-aged patients between 2002-2011, primarily due to the expansion of the middle-aged population in the U.S., according to a new study presented today at the 2015 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Continued growth in utilization of hip replacement surgery in patients age 45 to 64, an increase in revision surgeries for this population as they age, and a nearly 30 percent decline in the number of surgeons who perform THR, could have significant implications for future health care costs, THR demand and access.

As the world looks to American innovation to fight Ebola, malaria, tuberculosis, and a host of other health threats, a new report released today on Capitol Hill warns budget battles in Washington are eroding preparedness at home and abroad at a time when scientific advances are poised to deliver new lifesaving drugs, vaccines, and diagnostics.

Young adolescents' judgements on how risky a situation might be are most influenced by what other teenagers think, while most other age groups are more influenced by adults' views, finds a new survey by psychologists.

BioBlast Pharma Ltd. has announced positive preclinical in vitro and in vivo proof-of-concept study results for its mitochondrial protein replacement therapy drug candidate (BB-FA) for Friedreich's Ataxia.

Friedreich's Ataxia is an inherited disorder characterized by progressive deterioration of the muscular and nervous system that begins in the first or second decade of life and results in gait disturbance (ataxia), cognitive impairment, progressive heart disease and diabetes. According to Friedreich's Ataxia Research Alliance (FARA), about 1:50,000 people in the U.S. suffer from Friedreich's Ataxia. Most patients are wheelchair-bound within 15 years of diagnosis.

Antioxidants provide long-term protection against the chain reactions of free radical processes, in other words, of the molecules that are capable of causing cell damage and generating various diseases. Free radicals harm our body by causing, in the best of cases, ageing and, in the worse, serious diseases. Lettuce is rich in antioxidants, as it contains compounds like phenolic acids, flavonoids, anthocyanins, and vitamins A and C, among other things.

Reclusive giant pandas fascinate the world, yet precious little is known about how they spend their time in the Chinese bamboo forests. Until now.

A team of Michigan State University (MSU) researchers who have been electronically stalking five pandas in the wild, courtesy of rare GPS collars, have finished crunching months of data and has published some panda surprises in this month's Journal of Mammalogy.
