Pretty in pink: adult women do not remember being so obsessed with the colour, yet it is widespread in our young girls’ lives. It is not that pink is inherently (内在地) bad, but it is such a tiny slice of the rainbow and, though it may celebrate girlhood in one way, it also repeatedly and firmly

Does technology replace more jobs than it creates? What is the net balance between these two things? Until now, that has not been measured. But a new research project led by MIT economist David Autor has developed an answer, at least for U.S. history since 1940.The study uses new methods to examine how many jobs have been lost to machine
“There does appear to be a faster rate of automation, and a slower rate of augmentation, in the last four decades, from 1980 to the present, than in the four decades
The study finds that overall, about 60 percent of jobs in the U.S. represent new types of work, which have been created since 1940.To determine this, Autor and his colleagues
From about 1940 through 1980, for instance, jobs like elevator operator and typesetter(排字工人) tended to get automated. But at the same time, more workers —
Ultimately, the research suggests that the negative effects of automation on employment were more than twice as great in the 1980-2018 period as in the 1940-1980 period.There was a more

Using animals to test drugs intended for humans is controversial, with critics arguing there are other ways to ensure new medicines are safe and effective. But the scientists who carry out the research say animal studies remain necessary. Statistics indicate that in the UK around three million mice are being used for research and tens of millions worldwide.
Despite the difference in appearances, the genetic similarities with humans are
Animal Defenders International (ADI) is one of the groups that campaigns for an end to the use of animals in research. “We would argue that it is extremely outdated, and not very good science for humans,” says Fleur Dawes of ADI.
