...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.

Scientists had thought ginkgo extract might work as an anti-inflammatory agent to keep brain connections healthy and promote steady flow of nutrients to neurons. They also thought ginkgo, a strong antioxidant, helped inhibit oxidative damage to brain neurons caused by free radicals found in pollutants or made as a by-product of many metabolic processes. But if ginkgo were working in this way, says DeKosky, he and his team would almost certainly have detected a difference between the treatment and placebo groups.

...overall cognitive decline in the study participants. The average rate of change in performance on the tests, which were initially given every six months and then yearly, was similar for both the ginkgo and placebo groups.

Over the last six months of hearings, the court heard accounts of interrogators who ripped off toenails, suffocated prisoners with plastic bags, forced people to eat feces, electrocuted prisoners and drained blood to extract confessions. During the trial, Duch, 67, said that Cambodians should hold him to the "highest level of punishment." But he also begged for forgiveness, saying he was only "a cog in a running machine." Duch's defense team painted the former math instructor as a mid-level bureaucrat who didn...
