The Science ofthe Future

Until recently, the"science of the future" was supposed to be electronics andartificialintelligence. Today it seems more and more likely that the next greatbreakthroughs intechnology will be brought through a combination of those twosciences with organic chemistryand genetic engineering. This combination is thescience of biotechnology.

Organic chemistry enables usto produce marvelous synthetic (合成的) materials.However,it is still difficult to manufacture anything that has the capacity ofwool to conserve heat and alsoto absorb moisture. Nothing that we have beenable to produce so far comes anywhere near thecombination of strength,lightness and flexibility that we fred in the bodies of ordinaryinsects.Nevertheless, scientists in the laboratory have already succeeded in"growing" a material that has many of the characteristics of humanskin. The next step may well be "biotech heartsand eyes" which canreplace diseased organs in human beings. These will not be rejected by thebody,as is the case with organs from humans.

The application ofbiotechnology to energy production seems even more promising. In1996 the famousscience-fiction writer, Arthur C. Clarke, many of whose previouspredictionshave come true. He said that we may soon be able to developremarkably cheap and renewablesources of energy. Some of these power sourceswill be biological. Clarke and others havewarned us repeatedly that sooner orlater we wi/1 have to give up our dependence on non-renewable power sources.Coal, oil and gas are indeed convenient. However, using them alsomeans creatingdangerously high levels of pollution. It will be impossible to meet the growingdemandfor energy without increasing that pollution to catastrophic (灾难性的) levels unlesswe develop power sources that are both cheaper and cleaner.

It is attempting to think thatbiotechnology or some other "science of the future" can solveourproblems. Before we surrender to that temptation we should remember nuclearpower.Only a few generations ago it seemed to promise/imit/ess, cheap and safeenergy. Today thosepromises lie buried in a concrete grave in a place calledChernobyl, in the Ukraine.Biotechnology is unlikely, however, to break itspromises in quite the same or such a dangerousway.
