Researchers at six universities across the U.S., led by Dr. Steven DeKosky at the University of Virginia School of Medicine, report that elderly people taking ginkgo supplements showed no notable differences in scores on brain-function tests from people taking placebo pills. The team, which published its results Tuesday, Dec. 29, in the Journal of the American Medical Association, tested volunteers on a range of tasks, including memory, attention, language, and visual and spatial constructions, and found that the extract from the ancient tree did little to slow the decline of these functions.

...study is the largest and, with a mean follow-up of six years, also the longest to investigate the effects of ginkgo on the brain. An earlier analysis, also led by DeKosky, reported in 2008 that ginkgo supplements do not prevent the development of dementia or Alzheimer's disease in older people. Taken together, the two evaluations strongly suggest that ginkgo does little, if anything, to improve acuity in cognitive functions such as memory, language, and visual and spatial orientation...
...despite the double-digit victory and strong defensive performance, Harvard coach Tommy Amaker felt the Crimson looked sloppy at times. Harvard turned the ball over 14 times throughout the contest and led by just nine at the half...
...recalibrating U.S. military strategy in Afghanistan, the cost of the conflict kept being hammered home. In October, 58 U.S. soldiers were killed, the highest monthly tally since the war began in 2001. President Obama's plan to commit 30,000 more troops before beginning a drawdown in July 2011 led critics to question the logic of fighting a war that cannot, perhaps, be cleanly...
...lack of archaeologists at many sites has led militants and vandals to close in. Kashmir Smast, about 70 miles northwest of Islamabad, is a Hindu site, not Buddhist, and thus unusual for the area. "But there's no preservation, no one to look after the site," says Dr. Nasim Khan, professor of archaeology at the University of Peshawar. "The local people are damaging the site because of illegal diggings." In Swat, the Taliban have long attempted to destroy the Buddhist heritage of the region. In October 2007, as militants cemented their hold on the former tourist area, the Taliban dynamited...
