一只转基因克隆兔已于3个月前在沪诞生。根据上海交大医学院项目组检索,这是有新闻报道和学术报道以来的世界首例转基因克隆兔。日前这只小兔子已通过分子生物学“身份鉴定”。这只转基因克隆兔携带有绿色荧光蛋白基因,将为今后大规模建立转基因兔动物模型、定向研究人类疑难杂症奠定基础。据介绍,兔子克隆胚胎发育率低、怀孕率低、出生后死亡率高,这些因素导致了科学家较难培育出转基因克隆兔。此前,法国一家研究所在2002年也用颗粒细胞克隆了一只兔子,但生下来后很快就死亡了。

The industrial age has been the only period of human history in which most people’s work has taken the form of jobs. The industrial age may now be coming to an end, and some of changes in work patterns which it brought may have to be reversed. This seems a discouraging thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history show, hasn’t meant economic freedom.

Employment became widespread when the enclosures(圈地运动)of the 17th and 18th centuries made many people dependent on paid work by taking them away from the use of the land, and thus from the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people’s homes. Later, as transport improved, first by rail and then by road, people traveled longer distances to their place of employment until, eventually, many people’s work lost all connection with their home lives and the places in which they lived.

Meanwhile, employment put women at a disadvantage. In pre-industrial times, men and women had shared the productive work of the household and village community. Now it became customary for the husband to go out to paid employment, leaving the unpaid work of the home and family to his wife. Tax and benefit regulations still assume this norm(准则)today, and restrict more flexible sharing of work roles between sexes.

It was not only women whose work status suffered. As employment became the dominant form of work, young people and old people were kept out — a problem now, as more teenagers disappointed and annoyed at school and more retired people want to live active lives.

All this may now have to change. The time has certainly come to switch some efforts and resources away from the utopian(乌托邦)goal of creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs.
