What will the world be like in fifty years?
This week some top scientists, including Nobel Prize winners, gave their vision of how the world will look in 2056,fron gas-powered cars to extraordinary health advances, John
Ingham reports on what the world’s finest minds believe our futures will be.
For tho 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.

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 itlf.
The prediction is that we will have found a source of inexbaustible, safe, green energy, and that science will have killed off religion. If they are right we will have removed two of the main caus of war-our dependence on oil and religious prejudice.
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?
Of cour, all the 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.”
Living longer
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.
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 nt a kidney with the correct tissue type.

The organs would be entirely compod of human cells, grown by introducing them into animal hosts, and alloweing them to deveoop 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 el’s and we probably don’
t want to put a human brain ing an animal body.”
Richard Miller, a professor at the University of Michigan, thinks scientist could develop“an thentic anti-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”
Aliens

第八套广播体操完整版Conlin Pillinger ,professor of planerary sciences at the Open University,says:”I fancy that at least we will be able to show that life didi start to evolve on Mars well as Earth.”Within 50years he hopes scientists will prove that alien life came here in Martian meteorites(陨石).
Chris McKay,a planetary scientist at NASA’s Ames Rearch Center.believes that in 50
years we may find evidence of alien life in ancient permanent forst of Mars or on other planers.
