[font=Times New Roman][color=#000000]What will the world be like in fifty years?[/color][/font]
[font=Times New Roman][color=#000000]This week some top scientists, including Nobel Prize winners, gave their vision of how the world will look in 2056, ron gas-powered cars to extraordinary health advances, John Ingham reports on what the world’s finest minds believe our futures will be.[/color][/font]
[font=Times New Roman][color=#000000]For those of us lucky enough to live that long,2056 will be a world of almost perpetual youth, where obesity is a remote memory and robots become our companions.[/color][/font]
[font=Times New Roman][color=#000000]We will be rubbing shoulders with aliens and colonizing outer space. Better still, our descendants might at last live in a world at peace with itself.[/color][/font]
[font=Times New Roman][color=#000000]The prediction is that we will have found a source of inexhaustible, safe, green energy, and that science will have killed off religion. If they are right we will have removed two of the main causes of war-our dependence on oil and religious prejudice.[/color][/font]
[font=Times New Roman][color=#000000]Will we really, as today’s scientists claim, be able to live for ever or at least cheat the ageing process so that the average person lives to 150?[/color][/font]
[font=Times New Roman][color=#000000]Of course, all these predictions come with a scientific health warning. Harvard professor Steven Pinker says: “This is an invitation to look foolish, as with the predictions of domed cities and nuclear-powered vacuum cleaners that were made 50 year ago.”[/color][/font]
[font=Times New Roman][color=#000000]Living longer[/color][/font]
[font=Times New Roman][color=#000000]Anthony Atala, director of the Wake Forest Institute in North Carolina, belives failing organs will be repaired by injecting cells into the body. They will naturally to straight to the injury and help heal it. A system of injections without needles could also slow the ageing process by using the same process to “tune” cells.[/color][/font]
[font=Times New Roman][color=#000000]Bruce Lahn, professor of human genetics at the University of Chicago, anticipates the ability to produce “unlimited supplies” of transplantable human organs without the needed a new organ, such as kidney, the surgeon would contact a commercial organ producer, give him the patient’s immuno-logical profile and would then be sent a kidney with the correct tissue type.[/color][/font]
[font=Times New Roman][color=#000000]These organs would be entirely composed of human cells, grown by introducing them into animal hosts, and allowing them to develop into and organ in place of the animal’s own. But Prof. Lahn believes that farmed brains would be “off limits”. He says: “Very few people would want to have their brains replaced by someone else’s and we probably don’t want to put a human braining an animal body.”[/color][/font]
[font=Times New Roman][color=#000000]Richard Miller, a professor at the University of Michigan, thinks scientist could develop “an then icanti-ageing drugs” by working out how cells in larger animals such as whales and human resist many forms of injuries. He says: “It’s is now routine, in laboratory mammals, to extend lifespan by about 40%. Turning on the same protective systems in people should, by 2056, create the first class of 100-year-olds who are as vigorous and productive as today’s people in their 60s”[/color][/font]
[font=Times New Roman][color=#000000]Aliens[/color][/font]
[color=#000000][font=Times New Roman]Conlin Pillinger ,professor of planerary sciences at the Open University, says: fancy that at least we will be able to show that life didi start to evolve on Mars well as Earth.” ithin 50years he hopes scientists will prove that alien life came here in Martian meteorites([/font][font=宋体]陨石[/font][font=Times New Roman]).[/font][/color]
[font=Times New Roman][color=#000000]Chris McKay, a planetary scientist at NASA’s Ames Research Center. believes that in 50 years we may find evidence of alien life in ancient permanent forst of Mars or on other planers.[/color][/font]
[font=Times New Roman][color=#000000]He adds: There is even a chance we will find alien life forms here on Earth. It might be as different as English is to Chinese.[/color][/font]
[font=Times New Roman][color=#000000]Priceton professor Freeman Dyson thinks it “likely” that life form outer space will be discovered defore 2056 because the tools for finding it, such as optical and radio detection and data processing, are improving.[/color][/font]
[font=Times New Roman][color=#000000]He says: As soon as the first evidence is found, we will know what to look for and additional discoveries are likely to follow quickly. Such discoveries are likely to have revolutionary consequences for biology, astronomy and philosophy. They may change the way we look at ourselves and our place in the universe.[/color][/font]
[font=Times New Roman][color=#000000][/color][/font]
[font=Times New Roman][color=#000000]Colonies in space[/color][/font]
[font=Times New Roman][color=#000000]Richard Gottprofessor of astrophysics at Princeton, hopes man will set up a self-sufficient colony on Mars, which would be a “life insurance policy against whatever catastrophes, natural or otherwise, might occur on Earth.[/color][/font]
[font=Times New Roman][color=#000000]“The real space race is whether we will colonise off Earth on to other worlds before money for the space program me runs out.”[/color][/font]
[font=Times New Roman][color=#000000][/color][/font]
[font=Times New Roman][color=#000000]Spinal injuries[/color][/font]
[font=Times New Roman][color=#000000]Ellen Heber-Katz,a professor at the Wistar Institude in Philadelphia, foresees cures for inijuries causing paralysis such as the one that afflicated Superman star Christopher Reeve.[/color][/font]
[color=#000000][font=Times New Roman]She says:”I believe that the day is not far off when we will be able to profescribe drugs that cause severes([/font][font=宋体]断裂的[/font][font=Times New Roman]) spinal cords to heal, hearts to regenerate and lost limbs to regrow.[/font][/color]
[font=Times New Roman][color=#000000]“People will come to expect that injured or diseased organs are meant to be repaired from within, in much the same way that we fix an appliance or automobile: by replancing the damaged part with a manufacturer-certified new part.” She predict that within 5 to 10 years fingers and toes will be regrown and limbs will start to be regrown a few years later. Reparies to the nervous system will start with optic nerves and, in time, the spinal cord. “Within 50years whole body replacement will be routine,” Prof.Heber-Katz adds.[/color][/font]
[font=Times New Roman][color=#000000]Obesity[/color][/font]
[font=Times New Roman][color=#000000]Sydney Brenner, senior distinguished fellow of the Crick-Jacobs Center in California, won the 2002 Noblel Prize for Medicine and says that if there is a global disaster some humans will survive-and evolition will favour small people with bodies large enough to support the required amount of brain power. “Obesity,” he says. “will have been solved.”[/color][/font]
[font=Times New Roman][color=#000000]Robots[/color][/font]
[font=Times New Roman][color=#000000]Rodney Brooks, professor of robotice at MIT, says the problems of developing artificial intelligence for robots will be at least partly overcome. As a result,” the possibilities for robots working with people will open up immensely”[/color][/font]
[font=Times New Roman][color=#000000]Energy[/color][/font]
[font=Times New Roman][color=#000000]Bill Joy, green technology expert in Califomia, says: “The most significant break throught would be to have an inexhaustible source of safe, green energy that is substantially cheaper than any existing energy source.”[/color][/font]
[font=Times New Roman][color=#000000]Ideally, such a source would be safe in that it could not be made into weapons and would not make hazardous or toxic waste or carbon dioxide, the main greenhouse gas blamed for global warming.[/color][/font]
[font=Times New Roman][color=#000000]Society[/color][/font]
[color=#000000][font=Times New Roman]Geoffrey Miller, evolutionary psychologist at the University of New Mexico, says:” The US will follow the UK in realizing that religion is nor a prerequisite ([/font][font=宋体]前提[/font][font=Times New Roman])for ordinary human decency.[/font][/color]
[font=Times New Roman][color=#000000]。。。。。。。。。。。。。。。。。。。[/color][/font]
