...Bloch received the Nobel Prize for Medicine or Physiology. He shared the award with Feodor Lynen, a biochemist from Munich. The men received the prize "for their discoveries concerning the mechanism and regulation of the cholesterol and fatty acid metabolism," according to the transcript of the award presentation speech...
Sounds plausible enough until you talk to James Olson, a biochemist at Iowa State University who studies vitamin A's effects on the body. Olson tells us that while these enzymes probably exist, there are no good studies proving that they're powerful enough to make the esters get to work. For their part, cosmetics manufacturers reply that you don't need a lot of enzyme to have an effect. The majority of the products we tested used derivatives of vitamin A, with the highest being L'Oreal's Plenitude at .1%. Dermatologists are divided on whether that's enough...
...actions of individual genes, moreover, make a lot more sense in the context of other genes. "Right now," says Stanford biochemist Patrick Brown, "it's like watching a movie on TV a few pixels at a time and trying to figure out the overall story. Having the complete genome sequence is something categorically different, like going from 100 scattered pixels on your screen to having the whole image. There will be a substantial increase in the rate at which discoveries are made...
...know that ecstasy is versatile. Actually, that's one of the first things we knew about it. Alexander Shulgin, 74, the biochemist who in 1978 published the first scientific article about the drug's effect on humans, noticed this panacea quality back then. The drug "could be all things to all people," he recalled later, a cure for one student's speech impediment and for one's bad LSD trip, and a way for Shulgin to have fun at cocktail parties without martinis...
While the optimist in each of us wants these claims to be true, the findings from the task force, led by Tufts University biochemist Norman Krimsky, deliver a sobering dose of reality. There is insufficient scientific evidence, the team concludes, to support the notion that taking megadoses of dietary antioxidants can prevent chronic diseases. But the report goes even further. "Extremely large doses [of antioxidants]," it says, "may lead to health problems." Megadoses of vitamin E, for instance, can put you at greater risk of bleeding, while too much vitamin C causes diarrhea and may interfere with cancer treatments. Take...
