Tiny transmitters(发射机) fixed on the backs of the blue-green bees have allowed scientists to follow the insects as they fly for miles in search of rare flowers.

Working in Panama,scientists caught 17 bees of the common species and fixed a 300 milligram radio light onto the back of each.The signals they sent out were used to follow their movements in and around the forest where they lived.

Professor Martin,from Princeton University,US,and the Max Planck Institute for Ornithology in Germany,said,“By following the radio signals,we discovered that male bees spent most of their time in small centre areas,but could take off and visit areas farther away.One male even crossed over the shipping lanes in the Panama Canal,flying at least 5km,and returned a few days later.”

Researchers have struggled to follow the movements of bees before,following bees marked with paint or using radar which doesn’t work well in forests.

“Carrying the transmitter could reduce the distance that the bees travel,but even if the flight distances we record are the shortest distances that these bees can fly,they are impressive,long-distance movements,” said Dr.Roland Kays,from New York State Museum,a co-author of the research published today in the on-line journal.“This result helps to explain how these bees’ pollination(授粉) can be so rare.” Pollination by bees and other insects is the key to the diversity and continued growth of flowers and trees in some forests.

The new study is the first to use radio transmitters to follow bees in a forest.Similar research may now be carried in temperate forests,where bees also play a vital role.

As a result of his kindness, many people came to visit him. Among them was a newspaperman. During their talk, Johnson remarked that he was seventy-five and expected to live to be a hundred.

Computer programmer David Jones earns £35,000 a year designing new computer games, yet he cannot find a bank ready to let him have a credit card (信用卡). Instead, he has been told to wait another two years, until he is 18. The 16-year-old works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David’s firm releases (推出) two new games for the fast throwing computer market each month.

But David’s biggest headache is what to do with his money. Even though he earns a lot, he cannot drive a car, take out a mortgage (抵押贷款), or get credit cards. David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said. David spends some of his money on records and clothes, and gives his mother 50 pounds a week. But most of his spare time is spent working.

“Unfortunately, computing was not part of our studies at school,” he said. “But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.” David added:“I would like to earn a million and I suppose early retirement is a possibility. You never know when the market might die away.”
