Q: "Mobile phones killed our man,"screamed one headline last year. Also came claims that an unpublished study had found that mobile phones cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones heat the brain.

For anyone who uses a moblie phone, these are worring times. But speak to the scientists whose work is the focus of these scared and you will hear a different story.

What we do have, however, are some results suggesting that mobile phones'emission have a variety of strange effects on living tissue that can't be explained by the general radiation biology. And it's only when the questions raised by these experients are answered that we'll be able to say for sure what moblie phones might be doing to the brain.

One of the odd effects comes from the now famous"merrory loss" study. Alan Preece and his colleagues at the prefix = st1 /UniversityofBristolplaced a device that imitated the microwave emission of mobile phones to the left ear of volunteers. The volunteers were all goood at recalling words and pictures they had been shown on a computer screen. Preece says he still can't comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive abilities."I'm pretty sure there is no effect on short-term memory," he says.

Another expert, Tatterasll, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses exposed to microwaves become more----rather than less-----receptive to under-going changes linked to the memory formation.

It would be an even happier outcome if microwave turned out to be good for you. It sounds crazy, but a couple of years ago a team led by William Adey at the Veterans Affairs Medical Center in California, found that mice exposed to microwave for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.

So should we forget about mobile phone radiation causing brain tumours and scrambling our minds?

"If it doesn't certainly cause cancer in animals and cells, then it probably isn't going to cause cancer in humans,"says William. And while there's still no evidence that mobile phone does mangle your memories or give your cancer, the _ is:Don't panic.

Q: John Fitzgerald "Jack" Kennedy (May 29, 1917 November 22, 1963), commonly referred to by his initials JFK, was an American statesman who served as the 35th President of the United States from January 1961 until his assassination in November 1963.

Kennedy was born in Brookline, Massachusetts, to Joseph P. Kennedy, Sr. and Rose Kennedy. A scion of the Kennedy family, he graduated from Harvard University in 1940 before joining the United States Naval Reserve the following year. During World War II, Kennedy commanded a series of PT boats in the Pacific theater and earned the Navy and Marine Corps Medal for his service. After the war, Kennedy represented Massachusetts's 11th congressional district in the United States House of Representatives from 1947 until 1953. He was subsequently elected to the U.S. Senate and served as the junior Senator from Massachusetts from 1953 until 1960. While serving in the Senate, he published "Profiles in Courage", which won the Pulitzer Prize for Biography. In the 1960 presidential election, Kennedy narrowly defeated Republican opponent Richard Nixon, who was the incumbent Vice President.

Q: When Paul was a boy growing up in Utah, he happened to live near a copper smelter , and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest. One day a young visitor looked at this wasteland and called it an awful area. Paul knocked him down. From then on, something happened inside him.

Years later Paul was back in the area, and he went to the smelter office. He asked if they had any plans or if they would let him try to bring the trees back. The answer from that big industry was "No".

Paul then went to college to study the science of plants. Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds. It would be a waste of his life to try to do it. Everyone knew that, he was told. Even if he was knowledgeable as he had expected, he wouldn't get his idea accepted.

Paul later got married but his dream would not die. And then one night he did what he could with what he had. As Samuel Johnson wrote, "It is common to overlook what is near by keeping the eye fixed on something remote. Attainable good is often ignored by minds busied in wide ranges." Under the cover of darkness, he went secretly into the wasteland and started planting.

And every week, he made his secret journey into the wasteland and planted trees and grass. For fifteen years he did this against _ . Slowly rabbits appeared. Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing.

Now the place is fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has. It took him until his hair turned white, but he managed to keep that impossible vow he made to himself as a child.

1. Who went to college?
2. Where did he grow up?
