...white-backed vulture population has declined a catastrophic 99.9% in the past 15 years; once estimated at 40 million, the global number now sits below 11,000. The long-billed and the slender-billed vulture populations have also fallen nearly 97%, according to a 2007 study published in the Journal of the Bombay Natural History Society.

...that may not be such a good idea, say researchers in a commentary appearing in CA: A Cancer Journal for Clinicians, a publication of the American Cancer Society. The authors looked at studies pitting preoperative use of MRI, which relies on magnetic waves, against mammograms and similar tests that use radiation to take pictures of breast tissue. Researchers found that women choosing MRIs often ended up with more aggressive surgery - much of which wasn't necessary - than women who did not use the scans. What's more, employing the newer and more sensitive MRI technology did not improve a woman...
...most valuable recent advances in medical technology. But doctors are gorging on it: the number of CAT scans performed in the U.S. each year has leapt more than 200% in the past decade, and a third of them are likely unnecessary, according to the New England Journal of Medicine. The overuse is acute in cities like Miami because doctors and hospitals feel they have to justify the glut of CT machines and related personnel they have on hand...
...study suggests that doctors may be overlooking some significant benefits of heavy-lifting activity for thousands of patients like Jefferson. Published in the Aug. 13 issue of the New England Journal of Medicine, the study is the largest and longest of its kind to date. University of Pennsylvania researchers recruited 141 breast-cancer patients with a diagnosis of stable lymphedema. Half of them participated in a biweekly 90-min. weight-lifting program, which involved the slow, progressive addition of weight machines and free weights, up to as much weight as patients could comfortably lift; the other half of the patients...
...another decision: whether to keep schools open. Young students are known by influenza epidemiologists as "super spreaders" because they shed more flu virus when ill, are unlikely to practice good hand hygiene, and are in close contact with parents and peers. Writing in the August edition of British medical journal the Lancet Infectious Diseases, researchers from Imperial College in London predicted that early and prolonged school closures could ease the burden on hospitals by reducing the number of cases at the peak of the pandemic. They cited a previous study in France that predicted that up to 18% more people...
