Despite its unusual names, Boo. com has been quite successful in the field of women's fashion.
A book to be published in Britain this week, The End of Science, argues persuasively that this is the case. Its author, John Horgan, is a senior writer for Scientific American magazine, who has interviewed many of today's leading scientists and science philosophers. The shock of realizing that science might be over came to him, he says, when he was talking to Oxford mathematician and physicist Sir Roger Penrose.
The End of Science provoked a wave of denunciation (谴责) in the United States last year. "The reaction has been one of complete shock and disbelief," Mr. Horgan says.
The real question is whether any remaining unsolved problems, of which there are plenty, lend themselves to universal solutions. If they do not, then the focus of scientific discovery is already narrowing. Since the triumphs of the 1960s—the genetic code, plate tectonics (快板构造税) , and the microwave background radiation that went a long way towards proving the Big Bang—genuine scientific revolutions have been scarce. More scientists are now alive, spending more money on research, that ever. Yet most of the great discoveries of the 19th and 20th centuries were made before the appearance of state sponsorship, when the scientific enterprise was a fraction of its present size.
Were the scientists who made these discoveries brighter than today's？ That seems unlikely. A far more reasonable explanation is that fundamental science has already entered a period of diminished returns. "Look, don't get me wrong," says Mr. Horgan. "There are lots of important things still to study, and applied science and engineering can go on for ever. I hope we get a cure for cancer, and for mental disease, though there are few real signs of progress."
The sentence "most of the best things have already been located" could mean______.
With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That's a move similar to what a Texas A＆M University researcher has been undertaking for the past five years in a project called "Noah's Ark".
Dr. Duane Kraemer, a professor in Texas A＆M's College of Veterinary Medicine and a pioneer in embryo (胚胎) transfer work and related procedures, said he salutes the Chinese effort and "I wish them all the best success possible. It's a worthwhile project, certainly not an easy one, and it's very much like what we're attempting here at Texas A＆M—to save animals from extinction".
Noah's Ark is aimed at collecting eggs, embryos, semens (精子) and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Kraemer says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2,000 species of mammals, birds and reptiles will become extinct over the next 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
"The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy. It takes a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who is one of the leaders of the Missyplicity Project at Texas A＆M, the first-ever attempt at cloning a dog.
"They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly applaud their effort, and there's a lot we can learn from what they are attempting to do. It's a research that is very much needed."
The aim of "Noah's Ark" Project is to______.
According to the last paragraph, the typical volunteer now may be______.
