Culture, not biology, underpins math gender gap
— 00:50 GMT | HealthFor more than a century, the notion that females are innately less capable than males at doing mathematics, especially at the highest levels, has persisted in even the loftiest circles…
Cost shifting may make arthritis medications too expensive for Medicare beneficiaries
— 00:45 GMT | HealthBiologic disease-modifying antirheumatic drugs (DMARDs) such as adalimumab, etanercept and infliximab are effective at reducing symptoms and slowing progression of rheumatoid arthritis (RA). These drugs act more quickly, require less laboratory monitoring, and are better tolerated than nonbiologic DMARDs, but they are also up to 100 times more expensive. Insurance plans differ greatly in their coverage of and cost sharing for biologic DMARDs, sometimes shifting a large portion of the cost of patients. A new study examined the cost-sharing structures for biologic DMARDs in Part D plans and the resulting cost burden to patients. The study was published in the June issue of Arthritis Care and Research…
Study examines relationship between bone density and erosion in arthritis
— 00:40 GMT | HealthRheumatoid arthritis (RA), the most common form of inflammatory arthritis, affects almost three percent of people over age 65. RA patients experience pain, functional limitations and two forms of disabling bone disease: focal erosions and osteoporosis. After five years of disease, up to 50 percent of RA patients show evidence of focal erosions and RA doubles the risk of osteoporosis and fractures. A new study examined the relationship between these two RA-related processes, in the hopes of providing insight into the underlying pathophysiology of RA-related bone disease. The study was published in the June issue of Arthritis and Rheumatism…
Cell phone ringtones can pose major distraction, impair recall
— 00:35 GMT | HealthA flurry of recent research has documented that talking on a cell phone poses a dangerous distraction for drivers and others whose attention should be focused elsewhere. Now, a new study in the Journal of Environmental Psychology finds that just the ring of a cell phone may be equally distracting, especially when it comes in a classroom setting or includes a familiar song as a ringtone…
Be your best friend if you'll be mine: Penn's Alliance Hypothesis for Human Friendship
— 00:30 GMT | HealthUniversity of Pennsylvania psychologists studying the cognitive mechanisms behind human friendship have determined that how you rank your best friends is closely related to how you think your friends rank you. The results are consistent with a new theory called the Alliance Hypothesis for Human Friendship, distinct from traditional explanations for human friendship that focused on wealth, popularity or similarity…
Oestrogen linked to lowered immunity in fish
— 00:25 GMT | EnvironmentExposure to oestrogen reduces production of immune-related proteins in fish. This suggests that certain compounds, known as endocrine disruptors, may make fish more susceptible to disease…
Diet may reduce risk of prostate cancer
— 00:20 GMT | HealthA new review published in the Journal of Human Nutrition and Dietetics assessed whether certain modifications in diet have a beneficial effect on the prevention of prostate cancer. Results suggest that a diet low in fat and red meat and high in fruits and vegetables is beneficial in preventing and treating prostate cancer…
Tai chi improves pain in arthritis sufferers

Insomniac flies resemble sleep-deprived humans
— 00:10 GMT | BiologyResearchers at Washington University School of Medicine in St. Louis have created a line of fruit flies that may someday help shed light on the mechanisms that cause insomnia in humans. The flies, which only get a small fraction of the sleep of normal flies, resemble insomniac humans in several ways…
Cassini finds Titan's clouds hang on to summer
— 00:05 GMT | AstronomyCloud chasers studying Saturn's moon Titan say its clouds form and move much like those on Earth, but in a much slower, more lingering fashion. Their forecast for Titan's early autumn - warm and wetter. Scientists with NASA's Cassini mission have monitored Titan's atmosphere for three-and-a-half years, between July 2004 and December 2007, and observed more than 200 clouds…
