“The U.S.Food and Drug Administration(FDA)is considering to put stricter limits over tanning salons(晒黑廊)and wants to ban anyone younger than 18 years of age from using a tanning bed,”an advisory panel(专家团)announced last week.

The panel is calling for tighter controls on the industry such as requiring teenagers to get the approval from their parents before using tanning beds or limiting the use of artificial tanning to a certain age.“Given the absence of any demonstrated benefits,I think it is an obligation for us to ban artificial tanning for those under 18,”said panelist Dr.Michael Olding.

Along with a possible ban for teenagers,the panel also recommended that visible warning labels should be placed either on the tanning machines or in the salons in order to caution tanners of the possible dangers.In addition,the committee decided that stricter regulations and classifications were critical to make the machines safer.At this time the machines are categorized as FDA Class 1 devices,the ones that are least likely to cause harm.In case the FDA decided to change their classification from Class 1 to Class 2,as advised by the panel,the FDA could limit the levels of radiation the machines emit.Class 2 devices include X?ray machines and powered wheelchairs.

Getting a tan,whether from a tanning bed or the sun,increases the risk of developing skin cancer.Last year,the World Health Organization's International Agency for Research on Cancer (IARC)declared tanning beds as “carcinogenic(致癌的)to humans”.It was discovered that young individuals in their teens and 20s who use tanning beds on a regular basis have a 75 per cent higher risk of suffering from melanoma(黑素瘤),the deadliest form of skin cancer.According to the American Cancer Society,melanoma accounted for nearly 69,000 cases of skin cancer in 2009 and will account for most (about 8,650)of the 11,590 mortality cases due to skin cancer each year.

The Internet can be a great way to connect with people.The latest web craze is social networking on websites such as MySpace.More than 65 million young people use online social networking sites.

That cyberspace(网络空间)trend is causing problems in school,however.In a recent survey,nearly 36 percent of school administrators said that social networking sites troubled learning in their districts.Should school districts ban sites like MySpace?

Teachers are worried that some students use social networking to post personal information and to cyber bully(恐吓)other students.One of the biggest dangers comes from people who find out kid’s personal information.

Many districts have blocked students from accessing or using social networking sites from school computers,and some have suspended(暂缓)students for posting harmful material on those sites from their home computers.Nearly two-thirds of US kids have computers in their homes,according to the US Census Bureau.

It is important to keep in mind that just blocking access to social web sites at school is not the end of the story,” warns NSBA executive director Anne Bryant,“Most of the misuse of these sites takes place at home but still affects the classroom.”

Some educators aren’t as quick to pull the plug on social networking.They say the main problem with sites like MySpace is that students don’t understand the dangers involved in using them.“Many students are posting personal information about themselves without regard to who has access to that information,”Jim Hirsch said,“Schools should focus on educating their students and their parents on how to be safe online.”

Experts argue that too many schools are forbidding students to use social networking web sites without thinking about their educational benefits.“Social networking web sites can help connect students in the United States to their peers in other countries, providing invaluable lessons in foreign cultures,”explains Hirsch.
