“Mobile phone killed my man,” screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain.
For anyone who uses a mobile phone, these are worrying times. But speak to the scientists whose work is the focus of these scares and you hear a different story.
One of the oddest effects comes from the now famous “memory loss” study. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good 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(认识的)abilities. “I’m pretty sure there is no effect on short-term memory,” he says.
Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses(神经元突触) exposed to microwaves become more — rather than less — receptive to undergoing changes linked to memory formation.
An even happier outcome would be that microwaves 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 microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.
“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 absolute evidence that mobile phone use does damage your memories or give you cancer, the conclusion is: don’t be afraid.

The other day my aunt paid me a visit. She was overjoyed. “I got the highest mark in the mid-term examination!” She said. Don’t be surprised! My aunt is indeed a student, exactly, a college student at the age of 45.
“Compared with the late 70s,” she says, “now college students have many doors.” I was shocked when she first told me how she had had no choice in her major. Look at us today! So many doors are open to us! I believe there have never been such abundant opportunities for self-development as we have today. And my aunt told me that we should reach our goals by grasping all these opportunities.
The first door is the opportunity to study different subjects that interest us. My aunt was happy to study management, but she could also attend lectures on ancient Chinese poetry and on Shakespearean drama. As for myself, I am an English major, but I may also go to lectures on history.
The second door is the door to the outside world. Learning goes beyond classrooms and national boundaries. I have many fellow international classmates, and I am applying to an exchange program with a university abroad. As for my aunt, she is planning to get an MBA degree in the U.K.
The third door is the door to life-long learning. Many of my aunt’s contemporaries say she’s amazingly up-to-date for a middle-aged woman. She simply responds, “Age doesn’t matter. What matters is your attitude. I don’t think I’m too old to learn.” Yes, she is right. Since the government removed the age limit for college admissions, there are already some untraditional students, sitting with us in the same classrooms. Like them, my aunt is old but young in spirit with incredible energy and determination.
The doors open to us also pose challenges. For instance, we are faced with the challenge of a balanced learning, the challenge of preserving our fine tradition while learning from the West, and the challenge of learning continuously while carrying heavy responsibilities to our work and family. So, each door is a test of our courage, ability and judgment, but with the support of my teachers, parents, friends and my aunt, I believe I can meet the challenge head on.
