[1]While the Internet is a great tool it also makes it easier for bullies to pick on their prey（猎物）. According to the iSafe Foundation,over half of adolescents and teens have been bullied online, and about the same number have engaged in cyber bullying. Here is one story on how researchers are developing software to fight cyber bullies.
[2]Jeffery Michalenka learned his black belt in karate, but despite the fact he was a trained fighter he was often picked on by bullies. "Name called, teasing, when he was younger they would call him heifer(小母牛)," said Deborah Mich~denka,Jeffery's mother.
[3]As in Jeffery's case social media enables bullies to act anonymously while spreading their hatred rapidly. That's why artificial intelligence scientists at MIT are creating a software program to detect cyber bullying.
[4]"Bullies only talk about a few topics. It's usually racial or ethnic slurs(诽谤). It's things about personal appearance,social acceptance or rejection and threats' of violence,'' said Henry Lieberman, MIT artificial intelligence scientist.
[5]The researchers say subtle bullying is often hard to detect but their software can analyze sentences and determine if they are detrimental(有害的)to each gender. On the surface the sentence "you look pretty in pink" appears friendly if it is posted on a girl's wall. But on a boy's wall a cyber bully may be trying to anger the boy.
[6]"It may save a child's life and that's really what matters," Deborah concluded.
[7]Just one more way to fight cyber bullies before another child is hurt online.
[8]The team hopes social network sites will someday use this software to help detect bullying. The researchers are already working with Formspring,a social network site like Facebook. They also want the software to provide advice to the victims on what to do if they receive mean messages.

Elderly adults who regularly drink green tea may stay more agile ( 敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化化学物质) that may help stop the cell damage that can lead to disease. Researchers have been studying green tea' s effect on everything from cholesterol (胆固醇) to the risk of certain cancers, with mixed results so far.
They found those who drank the most green tea were the least likely to develop "functional disability", or problems with daily activities or basic needs, such as dressing or bathing.
Specifically ,almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled, compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older. Green tea lovers generally had healthier diets, including more fish, vegetables and fruit, as well as more education,lower smoking rates ,fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. But even with those factors accounted for, green tea itself was tied to a tower disability risk, the re-
searchers said.
People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it' s not clear how green tea might offer a buffer (缓冲) against disabilities, lead researcher Yasutake Tomata did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K,which means it could affect drugs that prevent blood clotting (凝固).
