higher risk for breast cancer， according to a study from Harvard T.H. Chan

School Of Public Health. The link was stronger among women who worked night

shifts.

Previous studies have suggested that exposure to light at night may lead to

decreased levels of the homone melatonin ， which can disrupt circadian

rhythms—our internal ’clocks’ that govern sleepiness and alertness—and， in turn，

lead to increased breast cancer risk.

The new study， the most comprehensive to date to examine possible links between

outdoor light at night and breast cancer， looked at data from nearly 110，000

women enrolled in the Nurses’ Health Study II from 1989-2013. The researchers

linked data from satellite images of Earth taken at night time to residential

addresses for each study participant， and also considered the influence of night

shift work. The study also factored in detailed information on a variety of

health and socioeconomic factors among participants.

Women exposed to the highest levels of outdoor light at night—those in the top

fift— had an estimated 14% increased risk of breast cancer during the study

period， as compared with women in the bottom fifth of exposure， the researchers

found. As levels of outdoor light at night increased， so did breast cancer

rates.

However， the association between outdoor light at night and breast cancer was

found only among women who were premenopausal and those who were current or past

smokers. In addition， the link was stronger among women who worked night shifts，

suggesting that exposure to light at night and night shift work contribute

jointly to breast cancer risk.

What can we learn from the first paragraph？

A.Women who live with higher levels of outdoor light may be at higher risk for cancer.

B.Men who live with higher levels of outdoor light may be at higher risk for cancer.

C.Women who worked night shifts may be at higher risk for breast cancer.

D.Men who worked night shifts may be at higher risk for breast cancer.

Wikipedia Imposes New Curbs （约束） on Editing Articles

Wikipedia， the famous online encyclopedia， is looking to impose more discipline with new restrictions on the editing of articles.

The latest changes come as Wikipedia tries to balance a need for credibility and a desire for openness. While anyone can still edit entries， the site is testing pages that won"t register changes until they are approved by an experienced Wikipedia editor. If the site"s users respond well to the test run， the new restrictions will apply to all entries for living people in the next few weeks.

The idea is to block the kind of vandalism（ 故意破坏 ）that has damaged some pages. In one of the most recent embarrassments， US Democratic Senators Robert Byrd was prematurely declared dead by the editors. Still， Wikipedia risks discouraging legitimate editing if restrictions on changes or additions become too burdensome， keeping articles from getting better or keeping up with events.

That may be especially true on more obscure pages with fewer active volunteers to approve edits timely.Aware of the risks， Wikipedia has set the criteria for "experienced editor" status relatively low.Users who are registered for a few days can give changes， said Jay Walsh， a spokesman for the nonprofit Wikimedia Foundation， which runs the site.

A more uniform. system for filtering changes on Wikipedia represents a step back from the site"s original philosophy， which called for creating the collective knowledge of volunteer editors without any major restrictions.

Some observers believe Wikipedia must continue tightening editing policies if it wants to gain credibility. "I"m just waiting for the other shoe to drop，" said Erie Goldman， director of the High Tech Law Institute at the Santa Clara University School of Law. "My hope is that Wikipedia still exists and is still considered a useful site，" Goldman said. "But it will be at that point a very tightly controlled site. It won"t have that veneer （外表） of a site that anyone can contribute to. They haven"t closed the drawbridge （吊桥） . People can still get in. But it keeps going up and up and up."

Separately， the Omidyar Network， a philanthropic （博爱的，慈善的 ） investment group started by eBay founder Pierre Omidyar， said on Tuesday it is committing $2 million over two years to the Wikimedia Foundation. Omidyar Network"s grant will support Wikimedia"s goals of bringing free educational content to people around the world and supporting more people to help create that content.
