A pill，code-named HT-0712，may make forgetfulness a thing of the past. It is being developed in the US and could go on sale within five years.

According to the newspaper The Sun，the wonder drug has been nicknamed “Mind Viagra”and has already been shown to boost the memory power of mice and flies. Next it will be tested on humans. This is just one of a number of drugs in a pharmaceutical (制药的) race to develop an increased memory pill. At least 12 US companies are believed to be working on similar projects.

Tim Tully，the founder of US drug company Helicon Therapeutics，who is in charge of the HT-0712 project，gave this practical example of its use for students：“If it takes two weeks to memorize a verse of Shakespeare，with one of these drugs you might be able to do it in two or three days. ”

“The memory drug business appears to be set to become a multi-million dollar industry，”experts say. This summer，100 Americans suffering mild memory loss will test HT-0712 in the first experiment on people.

“You don’t think better than you did before，you just get the facts in with less practice. There is a growing belief that memory and memory loss is just another treatable condition，”says Tully.

However，there is some doubt whether the drugs can really improve memory. In a study by the US’s Yale University Medical School，researchers suggested that the drug might affect other parts of the memory.

More and more companies are allowing their office workers to wear casual clothes to work in the United States. The change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday(but only on Friday). This became known as “dress-down Friday” or “casual Friday.” “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing,” said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale(士气). Only 4 percent of employers said that casual dress has a negative impact on productive. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”
