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 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.

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.

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 causes of war-our dependence on oil

and religious prejudice.

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 sent a kidney with the correct tissue type.

These organs would be entirely composed 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

else’s and we probably don’t want to put a human brain ing an animal body.”

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

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.

He ays:”As soon as the first evidence is found,we will know what to look for and additional discoveries are

Spinal injuries

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.

She says:”I believe that the day is not far off when we will be able to profescribe drugs that cause severes( 断裂

“People will come to expect that injured or diseased organs are meant to be repaired from within,inmuch 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
