Cellphones: is there a cancer link?
Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cellphones can cause brain tumors. “It’s apparent now that there’s a real risk,” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don’t have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs(电磁场) and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cellphone use and cancer risk.

Superman, Spider-Man, Batman and Iron Man ... .There is no shortage of superheroes. You find them in comic books, on the TV and the big screen.
In a survey of fans by the sci-fi and fantasy website, SFX.co.uk, Batman, 70 years old this year, was voted Britain's favorite superhero.
Unlike many crime-fighting superheroes Batman has no special powers. He can't fly like Superman or shoot a sticky web like Spider-Man.
Bruce Wayne is born to a wealthy Gotham City business family. However, when his parents are murdered his life changes completely.
Wayne feels anger at their deaths and guilty that he did not prevent them. He travels around the world learning how to fight. Upon returning to Gotham, he creates a disguise (伪装) to enable him to fight crime without being recognized.
A childhood fear of bats leads him to choose to dress as one. His idea is that through the bat person he can prove to himself that he has overcome his childhood fears.
Wayne is the CEO of the company he inherits (继承) from his father. He seems to live the lifestyle of a millionaire playboy. But this is a ruse (计策). He works hard at the image to allow himself the freedom he needs to do his work as a crime fighter. "Bruce Wayne, playboy" is the disguise Batman is the real person.
"Wayne is not a born superhero. Instead, he is a real, complex person," said Dace Golder, editor of the website. "He is the most realistic of all the superheroes. I am particularly interested in the emotional process by which a boy becomes a hero. His superhero qualities come from within."
