　　Habitual, long-term mobile phone users could soon know if they are at risk of developing cancer.

　　In what is believed to be a world-first study, human brain cells are being used to test the long-term effects of mobile phone radiation.

　　The study will use a device to simulate (模拟) the effect of longtime exposure(暴露) of the brain to electromagnetic radiation from mobile over a long period.

　　Testing will be done by researchers at Sydney's St. Vincent's Hospital . The project's chief investigator(调查者) , Peter, a French researcher, said the trial would test whether mobile phone radiation causes cancer in long-term users.

　　Testing will either prove people's fear, or show that there is no effect on human brain cells or perhaps that cells can become immune(免疫的) to electromagnetic radiation through repeated exposure.

　　During the study, brain cells will be exposed to electromagnetic radiation for an hour each day. Test results are expected in three to six months, with the final report to be published by the end of the year.

　　The research is unique because most previous studies have focused on short-term exposure on animal cells, which did help understand the effects of years of regular mobile phone use on human brain cells.

　　As mobile phones become increasingly popular throughout our society, it is important that we understand as much as possible about the long-term effect of electromagnetic exposure, if any, on human health.

When a storm is coming, most people leave the area as quickly as possible and head for safety…But there are a few people who will get into their cars and go straight for the center of the storm．These people are willing to risk being killed by floods or 100-Kilometer- an-hour winds for the excitement of watching the storm close up．
　 “Storm chasing (追逐)”is becoming an increasingly popular hobby，especially in the Midwest of the United States, where there are frequent storms between March and July．A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to l,000 kilometers to where the storm will be and waits for it to develop．
　  Although anyone can do it，storm chasing is extremely dangerous．The power of a big storm  can throw a cow into the air or destroy a whole house in seconds．Storm chasers are also often hurt in accidents caused by driving in a heavy rain．If you are a beginner, it is much safer to join a group for storm - chasing vacations during the storm season．
　  Even then，storm chasing is not all adventure and excitement．“Storm chasing is 95％driving，”says Daniel Lynch，who spends most of his summer storm-chasing．“Sometimes you
Can sit around for hours waiting for something to happen，and all you get is blue sky and a few light showers.”
　  However，for storm chasers，it is all worth it. “When you get close to a storm，it is the most exciting sight you will ever see in your life，”says Jasper Morley．“Every storm is an example of the power of nature．It is the greatest show on Earth．”
