Although the 2008 US presidential elections are still a long way off, candidates are already getting ready for the campaigns ahead.

For the Democrats(民主党人), the two leading candidates are a surprising pair. The first is Hillary Clinton, 60, the wife of former President Bill Clinton. The second is Barack Obama, 45, a Harvard educated senator(参议员).

It is the first time that the leading presidential candidates for a political party are either a woman or black. The dynamic pair has certainly gotten people's attention.

But the question remains, is America ready for either one?

It's not a simple question to answer. For the past 220 years, Americans have elected only white males to the nation's highest office. That can hardly be called a tradition of diversity. However, many people believe that 2008 will be the year that this changes.

"The white men that have been running the country recently have done such a bad job, at home and abroad, that maybe now is the time for a change," said Dorian Cool of San Francisco, California.

The polling numbers seem to back up his opinion: 86 percent of Americans say they would vote for a qualified woman. An impressive 93 percent say they would vote for a black man if he seemed right for the job. These numbers are much higher than they were just 20 years ago. They may suggest that Americans are ready to be led by a different type of person.

Still, there is a lot to overcome. Although women represent 51 percent of the American population, there are only nine female governors out of 50. Out of 100 senators, only 16 are women. The numbers are significantly lower for blacks in office.

Since the American Civil War, only two blacks have been elected governor and only three have been elected to the Senate.

Surely both candidates face difficult odds, but never before has there been so much support for either a female or a black candidate.

As Barack Obama himself said, "There is not a black America and a white America, a Latino America and an Asian America - there's the United States of America." If others share his vision, maybe the United States will end up with a new type of leader.

Sports shoes that work out whether their owner has done enough exercise to ensure time in front of the television have been invented in the UK.

The shoes ― dubbed(配音的)Square Eyes contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter(发射机)passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.

The design was inspired by a desire to combat(遏制)the rapidly ballooning waistlines among British teenagers, said Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London UK. “We looked at current issues and childhood obesity(过度肥胖)really stood out,” she told New Scientist. “And I wanted to deal with that with my design.”

Once the child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.

Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggested a child take 12,000 steps each day and watch no more than 2 hours of TV. So every 100 steps recorded by the Square Eyes shoes equals exactly one minute of TV time.

Clothes made in China were worn in European countries thousands of years before the first export factories sprung up(涌现出来). A thousand-year-old mummy, nicknamed Otzi, was wearing a Chinese jacket, latest research has found. But where and how he got the jacket has become a topic of great debate.

Otzi is the nickname of a well-preserved(保存完好)mummy from about 3300 BC. He was found in 1991 in the Otztal valley of the Alps, near the border between Austria and Italy. Two German tourists, Helmut and Erika Simon found him when they were climbing.

Otzi was thought to be the body of a soldier who fought during the first world war, but was found to be thousands of years older. Studying Otzi shows that the items with him were all of different ages. His arrows are 7,000 years old, the knife belonged to the time hundreds years later and the skin in which the man was dressed originally belonged to a goat that lived in China. Otzi's tattoo(纹身)shows that he might have been a person who practiced magic, according to Prauda, the official newspaper in Russia.

There are still thousands of mysteries about Otzi, yet the most famous and frightening one is his curse(咒语). Some researchers believe that Otzi's curse is still effective and will bring bad luck upon those who trouble his dead body. Indeed, several people who have touched the remains of the ancient man have already died.  (From Reuters 2007/12/30)
