...curious tale of how the brain got to McMaster University, in Hamilton, Ont., is equally fascinating. When Einstein died of a ruptured abdominal aneurysm in 1955, at the age of 76, the pathologist who did the autopsy at Princeton Hospital, Dr. Thomas Harvey, removed the brain, pickled it in formaldehyde--and kept it. Harvey had no credentials in neuroscience, and his unauthorized appropriation of Einstein's brain appalled and outraged many scientists. Possession was evidently a point in his favor, though. At the pathologist's request, the family agreed he could keep the organ for scientific study. But over...
Finally, in 1996, Harvey gave much of his data and a significant fraction of the tissue itself to Dr. Sandra Witelson, a neuroscientist who maintains a "brain bank" at McMaster for comparative studies of brain structure and function. These normal, undiseased brains, willed to science by people whose intelligence had been carefully measured before death, gave Witelson a solid set of benchmarks against which to measure the seat of Einstein's brilliant thoughts. To make the comparison as valid as possible, Witelson and her team compared Einstein's tissues with those of men close...
Last week's J.A.M.A. study seemed to tip the balance even further in raloxifene's favor. Researchers, led by Dr. Steven Cummings of the University of California at San Francisco, reported that taking the drug for 3 1/2 years reduced a woman's risk of developing breast cancer an average of 75%. By contrast, a study of tamoxifen completed last year showed that it reduced the incidence of breast cancer 45% over four years. As an added bonus, raloxifene also lowered the amount of LDL, or "bad cholesterol," in the blood...
...worked for frogs, Dr. Norman Levine reasoned, so why wouldn't Melanotan, a synthetic form of a natural hormone called Alpha MSH, work for humans? When frogs are given a shot of the stuff, it triggers rapid pigmentation of their skin. Perhaps, the University of Arizona dermatologist thought, Melanotan might help humans develop a tan without their having to expose themselves to the damaging ultraviolet rays...
...unforeseen bonus led Dr. Hunter Wessells, a University of Arizona urologist, to join the Melanotan team and help design tests of two groups of sexually dysfunctional men. Most of them also achieved erections after injections of the drug, including one man who had had no luck with Viagra. With Melanotan, he exulted, "the first time was absolutely incredible...
