...success adds fuel to yet another debate about deep-sea exploration. Some scientists insist that remote-controlled, robotic craft are no substitute for having humans on the scene. Says MBARI's Robison: "Whether you're a geologist or a biologist, being able to see with your own eyes is vital. That's a squiffy-sounding rationalization, but it's true." There are other advantages too, he notes. "The human eyes are connected to the best portable computer there is [the brain]. And when things go wrong, a person can often fix them faster, more easily and more efficiently than...
...vessels of an obese mouse to those of a normal-size mouse, creating a sort of artificial Siamese twin. What happened then was astonishing: the fat animal immediately began to lose weight. This suggested that the blood of nonobese mice carried a potent biochemical messenger, one that played a vital role in regulating appetite and metabolism. But the mysterious agent was present in such minuscule quantities that no one was able to isolate...
...fatter an animal is, the more leptin its cells should make. Normal mice then respond to weight gain by turning out more leptin. As a result, their appetites slacken and their energy consumption speeds up. But the obese mice cannot produce leptin, so their brains never receive this vital message. "These animals," marvels Friedman, "get fat because they think they're starving, and then when we give them the protein, they get thin because they think they...
...primitive creature may take apart an internal-combustion engine to study it but still never understand how it works--because its secret lies external to it, in the principle that explosions exert pressure. This insight is vital to understanding the engine. Hence it is no mystery why scientists haven't grasped the brain: they have been studying it solely on its own terms, much the way a primitive creature studies the engine. In my opinion, the answer lies outward. Scientists should ask, What real-world principle is the brain designed to exploit? TOM SALES Somerset, New Jersey...
