A new study shows that piloting a light aircraft remains an inherently risky business, accounting for over 90% of aviation-related fatalities*.

Deep in the Bolivian Amazon exists a forager-horticultural community called the Tsimane. Researchers look to them for insights on how the human body functioned prior to modern technologies, as their lifestyles remain the closest to that of our ancestors. Oftentimes researchers find how we have navigated away from our evolutionary path, such as the Tsimane having the lowest rates of dementia, the healthiest hearts, and low late-age inflammation than those living in industrialized nations. But, new research from Arizona State University, has discovered a universal experience – post-menopausal women experiencing increased blood lipid levels, such as cholesterol. 

Researchers funded by the National Institutes of Health (NIH) have found that a single injection of the antibiotic benzathine penicillin G (BPG) successfully treated early syphilis just as well as the three-injection regimen used by many clinicians in the United States and elsewhere. These findings from a late-stage clinical trial suggest the second and third doses of conventional BPG therapy do not provide a health benefit. The results were published today in The New England Journal of Medicine.
