A

When researchers made their first clone of an animal, Dolly the Sheep, in 1997, one doctor said: “The genie (妖怪) is out of the bottle.” But then he tried to actually create the “genie”--- by making a human clone.

Dr. Panayiotis Zavos told the public on October 5 that he could create the first cloned human before the end of the year. He is an expert on human copying and breeding from the University of Kentucky in the United States.

His workers have been stopped from carrying out research in most European Union countries, but Zavos said that fact was not slowing progress.

“It is going well enough so we may try the first production of cloned embryos in the very near future, that is, three or four months from now.” Cypriot-born Zavos said. He moved to the United States over 30 years ago.

Human cloning could, in effect, create a copy of another living or dead person.

But Zavos insisted there was nothing harmful in the project. As an expert on human reproduction, he said he is only interested in helping couples who cannot naturally have babies to have a child.

“We are not interested in cloning people like Bin Laden, Michael Jackson or Michael Jordan,” the doctor added.

“We are only interested in helping a father who does not have the ability to have a biological child of his own.”

Zavos said thousands of childless people from all over the world are helping in their research.

He would not say where the research is under way, but indicated that it is in more than one country.

The US airline industry is facing a new threat to its profits-heavier passengers, a report has found. According to the US Centers for Disease Control and Prevention, the average US adult put on ten pounds (4.5kg) of weight during the 1990s. Transporting the extra weight cost airlines an extra $275 million in fuel costs in 2000, the report says.

Earnings at airlines have already been under pressure due to the decreasing demand and a record increase in the price of crude oil(原油). In the US, a number of airlines have gone bust while others are struggling to survive in an ever more competitive market place. While it is relatively easy to check the weight of a traveler’s luggage and charge those that burst limits, it is much harder to regulate a person’s waistline. Some firms have toyed with the idea of(jokingly suggested) charging overweight travelers for two seats, but it is not a practice that has taken off industry-wide.

Last year, the American Federal Aviation Administration increased the average passenger weight they use to calculate aircraft loads by ten pounds. Since then, crude oil prices have hit record levels, with many firms responding by raising the fuel charge they add to ticket prices.

The rising level of obesity(过度肥胖)in the US and in Europe has prompted government health campaigns and harsh criticism of a number of food firms. Restaurant chain McDonald’s has taken the main force of the attack, and has in recent months reworked its menu to include healthier options, which has helped lift profits.

As with fast food restaurants, timely adjustment may be the best solution presently for American airlines. The prediction by experts, however, is that humans are set to become bigger.
