16、level, suggesting it could soon offer a cheaper, longer-lasting alternative to the traditional light bulb. The breakthrough adds to a growing trend that is likely to eventually make Thomas Edisons bright invention1 obsolete. LEDs are already used in traffic lights, flashlights, and architectural lig

17、hting. They are flexible and operate less expensively than traditional lighting.Michael Bowers, a graduate student at Vanderbilt University, was just trying to make really small quantum dots, which are crystals generally only a few nanometers big. Quantum dots contain anywhere from 100 to 1,000 elec

18、trons. Theyre easily excited bundles of energy, and the smaller they are, the more excited they get. Each dot in Bowers particular batch was exceptionally small, containing only 33 or 34 pairs of atoms.When you shine a light on quantum dots or apply electricity to them, they react by producing their

19、 own light, normally a bright, vibrant color. But when Bowers shined a laser on his batch of dots, something unexpected happened. He was surprised when a white glow covered the table. The quantum dots were supposed to emit blue light4, but instead they were giving off a beautiful white glow.Then Bow

20、ers and another student got the idea to stir the dots into polyurethane and coat a blue LED light bulb with the mix. The lumpy bulb wasnt pretty, but it produced white light similar to a regular light bulb.LEDs produce twice as much light as a regular 60 watt bulb and burn for over 50.000 hours. The

21、 Departmentof Energy estimates LED lighting could reduce U. S. energy consumption for lighting by 29 percent by 2025. LEDs dont emit heat, so theyre also more energy efficient. And theyre much harder to break.Quantum dot mixtures could be painted on just about anything and electrically excited to pr

We may be able to hang on to most of that youthful vigor even if we dont start to diet until old ag

26、e.Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouses liver genes can he made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation wont reverse other damage caused

27、by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.Spindlers 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 equ

28、ivalent 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 m

29、ice that had dieted nil 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 per cent of these gene changes.“This is the first indication that these effects kick in pretty

30、 quickly.” say 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. “Theres attracting and tempting evidence out there that it will work,” he says.If it does work in people, there m

31、ight 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 isnt sure the trade-off is worth it. “The mice get less disease, they live longer, but theyre hungry,” he says, “Even seeing what a diet does , its st
