Scientists Alan M.Goldberg and Thomas Hartung describe recent advances in replacing the use of animals in toxicology(毒物学)testing.Improvements in cell and tissue culture technologies,for example,allow a growing number of tests to be performed on human cells alone.Computer models are becoming increasingly complex and many could one day become more accurate than trials in living animals.
Since the late 1990s,Huntingdon Life Sciences--a company that conducts testing of substances on animals conducted by the Environmental Protection Agency and the Food and Drug Administration—has become a proving ground for aggressive strategies by animal-rights militants (好战分子).At a hearing,a Senate.committee listened to testimony(证词) against Huntingdon employees and financial institutions providing services to the company.One experimentation witness at the hearing insisted that any means necessary were justified(辩护) to spare animals’ lives;he has previously accepted the idea of murder to that end.
Use of animals in testing and in biomedical research continues to be necessary in many instances and is ethically(伦理道德地)preferable to experimenting on humans or giving up cures that could save human lives.But for the sake of people and animals alike,the development and acceptance of animal substitutes deserve enthusiastic support.
In some instances, substitutes are already thought as good or better than animals,but supervising agencies(监督机构)have yet to catch up.In both the European Union and the U.S.,scientists and companies wanting to use the new alternative tests complain that regulatory standards for proving a drug or chemical to be safe for humans force the continued use of animals.Thus,animal-loving Americans might turn to persuading the EPA and the FDA to speed validation(确认)of new methods so that they can be more widely employed.And animal advocates(保护者) who want to influence business could consider investing in the small biotech’s and large pharmaceutical(药品的) companies that are working to develop alternatives to animals in research.

The unwanted disturbing of a mobile phone ringing at a critical moment has led to some famously strong reactions
British actor Richard Grif-fiths,stopped a performance at the National Theatre and ordered The offending party to leave
Judge Robert Restaino went considerably further.He was hearing a session of domestic violence offenders in a court when proceedings were interrupted by rings of a phone.
“Everyone is going to jail unless I get that instrument now,” he shouted.
Over the next two hours,the judge entered a period of “incredible madness”.He began by ordering the doors of the court locked,and set the officers to searching for the phone.
When that failed to find the offending item he ordered each of the defendants(被告) present in the room up to his bench and in turn asked them if they had no idea, he sent each in turn to jail(监狱).
All 46 of them.
When a defendant protested the judge’s actions were not fair to those who didn’t possess the phone,Restaino replied:“I know it isn’t.
Judge’s actions caused chaos.Extra officers had to be drafted into the court to control the crowd.and booking officers at the city jail were at full stretch.“We were playing Twister in here”, one said at the time.
Fourteen of the defendants were shackled(束缚 )in irons and sent to the county jail.
The judge cooled off and later that afternoon released all 46.
The “two hours of viral lunacy(疯狂)”, has probably cost Restaino his job.The commission ruled that he should be removed from his $14,000 job.Restaino now has 30 days to appeal(上诉).
His lawyer pointed out that until that moment he had served 11 years as a judge without any disciplinary issues.“With the exception of two hours.his record is spotless.”

Shopping for clothes is not the same experience for a man as it is for a woman. A man goes shopping because he needs something. His purpose is settled and decided in advance. He knows what he wants, and his objective is to find it and buy it; the price is a secondary consideration. All men simply walk into a shop and ask the assistant for what they want. If the shop has it in stock, the salesman promptly shows it, and the business of trying it on follows at once. All being well, the deal can be and often is completed in less than five minutes, with hardly any chat and to everyone's satisfaction.
For a man, slight problems may begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman, as the name implies, tries to sell the customer something else, he offers the nearest he can to the article required. No good salesman brings out such a substitute(替代品)impolitely; he does so with skill: "I know this jacket is not the style you want, sir, but would you like to try it for size? It happens to be the colour you mentioned. Few men have patience with this treatment, and the usual response is: “This is the right colour and may be the right size, but I should be wasting my time and yours by trying it on.”
Now how does a woman go about buying clothes? In almost every respect she does so in the opposite way. Her shopping is not often based on need. She has never fully made up her mind what she wants, and she is only "having a look round". She is always open to persuasion; indeed she sets great store by what the saleswoman tells her, even by what companions tell her. She will try on any number of things. Uppermost in her mind is the thought of finding something that everyone thinks suits her. Contrary(相反的) to a lot of jokes, most women have an excellent sense of value when they buy clothes. They are always on the lockout for the unexpected bargain. Faced with a roomful of dresses, a woman may easily spend an hour going from one rail to another, to and fro(来回地), often retracing her steps, before selecting the dresses she wants to try on. It is a laborious process, but apparently an enjoyable one. Most dress shops provide chairs for the waiting husbands.

Once upon a time, on an isolated island in the Java sea, lived short people who dominated(支配, 占优势) the food chain. Standing no more than three and a half feet tall, these human ancestors hunted giant rats, lumbering lizards(笨拙的蜥蜴), and miniature elephants.
It sounds a bit like a fairy tale, but it's true. Unearthed relics on the island uncovered the remains of a race of tiny human ancestors. Homo floresiensis, as the newly discovered species has been named, apparently could date back to 13,000 years ago. This means they have a lot in common with modern humans.
So how and why did these people get so small? Scientists suspect that it's due to the fact that this race lived on an isolated island with limited resources. Take the miniature elephants for example. When elephants first came to the island either by swimming or by some kind of natural land raft, they were probably close to full size. But since there wasn't much to eat, over time smaller elephants lived longer and better. The smaller the elephant was, the less it had to eat to stay strong and healthy.
Scientists call this the "island role", and it can apply to humans as well as animals. Given the island's sparse(稀少) food supply, it makes sense that the early humans living there would have evolved (进化) a body size requiring less food to survive. So bigger isn't always better.
In the floresiensis, at least, getting smaller was the way to go.
