Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins. Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes. "This is the first indication that these effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C.. No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says. If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective. But Spindler isn't sure the trade-off is worth it. "The mice get less disease, they live longer, but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'." Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction.

C．Dieting might not be needed. ~ D．We have to begin dieting from childhood.

Recent studies have shown that the parts of the brain that we use to learn a task become active again during sleep. This activity, scientists suggest, could be the brain transferring memories from short-term to long-term storage. But the brain doesn't necessarily wait until the lights are out to begin processing those memories. To find out how the brain handles memories during waking hours, scientists gave 15 volunteers two tasks, each requiring different parts of the brain to learn. In one task, the subjects learned how to navigate a virtual town and then searched the town for an object. In the second task, they learned to predict where a sequence of dots would appear on a screen. Using a special machine, the researchers scanned the volunteers' brains right before and right after the tasks. They compared the two images to see whether the regions of the brain involved in learning the task were still active even after the task was completed. After a break, the scientists took a third image of each participant's brain. They wanted to determine whether these regions in the brain continued to be active after snore time had passed. They discovered that, for at least an hour after learning a task, the brain stays active. It appears to continue processing the new information. Furthermore, the images showed that distracting the subjects doesn't affect their ability to store memories. The processing continues even when they're thinking about or doing other things. Some scientists say this could mean that sleep isn't essential for storing memories. Others disagree. Until that's settled, it's probably still better to be on the safe side, getting plenty of sleep. According to the passage, ______. A．a good night's sleep helps your brain permanently file away lessons learned during the day. B．the brain has to wait until the lights are out to begin processing those memories C．perhaps it's safe for anyone to get plenty of sleep when it has not been proved unnecessary for memory D．attracting the subjects doesn't affect their ability to store memories.
