1 . Scientists have identified the order of the gene of the giraffe for the first time to help explain how the tallest animals on earth developed their remarkably long necks.
Being a giraffe is not easy. To pump blood two meters up from the chest to the brain calls for a powerful heart and twice the blood pressure of other mammals. Giraffes also need special safety system to let them bend down for a drink and raise their heads again without feeling Dizzy.
The animals* unique body structure has long been a puzzle for biologists, including Charles Darwin. Now, by comparing the gene of the giraffe with its closest relative, the short-necked okapi, scientists have solved part of the puzzle by studying changes in a small number of genes responsible both for regulating body shape and circulation. This suggests that the development of a long neck and a powerful heart went hand in hand, driven by a relatively small number of genetic changes.
The interpretation of the genetic factors behind the giraffe's remarkable heart system could also be instructive for human health, since the animals appear to avoid the kind of organ damage often found in people with high blood pressure.
The more fundamental question of why giraffes developed their long necks remains open, however. The apparently self-evident idea that it was to reach ever-higher food supplies has been challenged in the past 20 years by a competing belief that it is actually due to competition among fighting males for females.
Unlike long-necked birds, which have additional vertebrae (椎骨),giraffes have the same seven vertebrae found in all mammals, although theirs are greatly extended.

2 . Believe it or not but it is true. There are people who lose the ability to understand or use words due to brain damage. But they become extremely good at something else. They become experts at spotting liars. The condition in which people lose their power to understand or use words due to brain damage are called aphasia(失语症). A study conducted in Massachusetts, U.S., has clearly proved that aphasics make good lie detectors(测谎仪).
In the last 100 years, many doctors studying the brain have mentioned examples of this amazing power of patients suffering from aphasia. Recently, scientists conducted tests to see if all that was said about aphasics was true. They studied the powers of a mixed group of people. Some were normal; others were aphasic. And it was proved clearly that the normal volunteers still got fooled by words. The aphasics were far ahead of them in recognizing false speech. The results of the study were reported in the magazine Nature.
`Fourteen years ago, famous American doctor, Dr. Oliver Sacks, wrote about his experiences with aphasic patients in a book. He remembered a particular incident in a hospital. Patients from the aphasia room were watching TV. Their president, Ronald Reagan, was giving a speech. He was trying to put feelings into each and every word of his speech. But his speech had an opposite effect on the patients. They were not impressed. On the contrary, the whole room shook with their laughter. The aphasics knew that he did not mean a word of what he was saying.
Dr. Sacks saw aphasics as more gifted than normal people. Normal people “get carried away” by words. An aphasic cannot understand words. But he or she can still understand what is being said. He said most of the aphasics had this superior understanding. So, while normal people think of aphasic patients as brain damaged, they actually seem to understand human expressions better.

4 . “Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by logging on to a website, which sends a message to the model: a red and yellow “lost or stolen” banner pops up on its screen when it is started. Under the latest version of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, ‘You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. The default through the computer’s speakers is: “Help, this laptop is reported lost or stolen. If you are not my owner, please report me now.”
The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password prompt if they fear that the thief has also got hold of the access details.
If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase data remotely or lock down the computer.

8 . James Cleveland Owens was the son of a farmer and the grandson of black slaves. His family moved to Cleveland when he was 9. There, a school teacher asked the youth his name.
“J.C., ”he replied.
She thought he had said “Jesse”, and he had a new name.
Owens ran his first race at age 13. After high school, he went to Ohio State University. He had to work part time so as to pay for his education. As a second year student, in the Big Ten games in 1935, he set even more records than he would in the Olympic Games a year later.
A week before the Big Ten Meet, Owens accidentally fell down a flight of stairs. His back hurt so much that he could not exercise all week, and he had to be helped in and out of the car that drove him to the meet. He refused to listen to the suggestions that he give up and said he would try, event by event. He did try, and the results are in the record book.
The stage was set for Owens victory at the Olympic Games in Berlin the next year, and his success would come to be regarded as not only athletic but also political. Hitler did not congratulate any of the African American winners.
“It was all right with me,” he said years later. “I didn’t go to Berlin to shake hands with him, anyway. ”
Having returned from Berlin, he received no telephone calls from the president of his own country, either. In fact, he was not honored by the United States until 1976, four years before his death.
Owens Olympic victories made little difference to him. He earned his living by looking after a school playground, and accepted money to race against cars, trucks, motorcycles and dogs.
“Sure, it bothered me, ”he said later. “But at least it was an honest living. I had to eat.”
In time, however, his gold medals changed his life. “They have kept me alive over the years,” he once said. “Time has stood still for me. That golden moment dies hard.”
