...Senate's about to sprout another Sherlock. Utah Republican Orrin Hatch announced Thursday that the Senate Judiciary Committee is considering holding a hearing on the Justice Department's handling of the campaign fund raising investigation. "I really believe there are some things here that have to be explained," the chairman said. "We'll see what we can do to put one together." Just what America needs...
...including those of dancer Bill T. Jones. Yet rather than classic black and white, Opie's colorful backgrounds scream in yellow, viridian green, and an ultramarine blue, which matches the color of Vaginal Davis' garish eyeshadow. Except for the tufts of curly green hair which cover his head and sprout from his underarms and crotch, Davis stands stately before the viewer wearing nothing but little white socks and shoes. Opie's photograph fascinates us with a perfect combination of elegance and sleaze...
...gene nicknamed "sonic hedgehog" (after the popular video game Sonic the Hedgehog) determines the fate of neurons in the spinal cord and the brain. Like a strong scent carried by the wind, the protein encoded by the hedgehog gene (so called because in its absence, fruit-fly embryos sprout a coat of prickles) diffuses outward from the cells that produce it, becoming fainter and fainter. Columbia University neurobiologist Thomas Jessell has found that it takes middling concentrations of this potent morphing factor to produce a motor neuron and lower concentrations to make an interneuron (a cell that relays signals...
What guides an axon on its incredible voyage is a "growth cone," a creepy, crawly sprout that looks something like an amoeba. Scientists have known about growth cones since the turn of the century. What they didn't know until recently was that growth cones come equipped with the molecular equivalent of sonar and radar. Just as instruments in a submarine or airplane scan the environment for signals, so molecules arrayed on the surface of growth cones search their surroundings for the presence of certain proteins. Some of these proteins, it turns out, are attractants that pull the growth cones...
Temperature and rainfall patterns would shift in unpredictable ways. That might not pose a problem for agriculture, since farmers could change their crops and irrigate. Natural ecosystems that have to adapt on their own, however, could be devastated. Observes Oppenheimer dryly: "They cannot sprout legs and move to another climate." Perhaps a third of the world's forests, he says, might find themselves living in the wrong places...
