...white shower cap with a jungle of wires sticking out of it - that tracked their brain waves in order to determine their stage of slumber. Using an electroencephalogram (EEG), investigators monitored the sleepers' brain activity, and just when the squiggly lines on the screen showed that participants had entered deep sleep, researchers began playing a series of 25 of the sounds that the individual had heard earlier in the memory game. "[The volume] was a little over a whisper, probably much [quieter] than ... your iPod," says John Rudoy, one of the study's authors and a graduate student at Northwestern...
...nearly two centuries, researchers have suspected that sleep plays an important role in learning and memory. But it's only in the last decade that neuroscientists have discovered the most convincing evidence that memory is indeed dependent on sleep. The prevailing theory is that during deep sleep, the brain replays certain experiences from the day, which, in turn, strengthens the memory of what happened. It is thought that when it comes to factual memories, like names, faces, numbers or locations, memory consolidation happens only during deep sleep - a phase of non-rapid eye movement sleep. (The other broad type...
Beyond sensory stimulation during sleep, the timing of sleep may also be important to memory. Recent research suggests that deep sleep can strengthen factual memories, but only if the person naps within 12 hours of learning. In other words, if you have to memorize an SAT word list, you might be better off doing it at night rather than in the morning...
...will take more than that to challenge Berlusconi. Italy's center-left opposition is in disarray, as usual, having just elected its second new leader in six months. And for most Italians fed Mediaset fare for 30 years, Berlusconi's cultural outlook runs deep. Midway through the ironing contest on Quelli Che ... , the would-be schedine look up from their ironing boards to watch a comedy clip, in which three fat, old women compete in a beauty contest. The audience laughs, as do the presenters and the schedine...
Cooley was one of the original smoke jumpers, firefighters who parachute into remote blazes, often in deep wilderness. His first attempt was less than perfect--which was perhaps not surprising, considering that he had never been in an airplane before he took his practice runs. In July 1940, Cooley and a colleague leaped out of a plane over a fire in Idaho. Cooley's parachute lines became tangled on the way down, and he landed in the branches of a spruce tree. But the pair brought the blaze under control by the following morning...
