BEIJING, Sept. 8 (Xinhuanet) -- Middle-aged white women drinking alcohol moderately are more likely to stay healthy than nondrinkers, according to a new study from Harvard.The study has followed about 14,000 mostly white women since 1976.As a result, compared with teetotalers, those who had 3 to 15 alcoholic drinks weekly in their late 50s were 28 percent higher of being free from physical disability, chronic illness, mental health problems, and cognitive decline at the age of 70.Even having just one or two drinks per week increased a woman's odds of good health by 11 percent.However, women should be aware that even moderate drinking has been linked to an increased risk of breast cancer, said Qi Sun, M.D., a lead author of the study and a nutrition researcher at the Harvard School of Public Health.These findings don't necessarily apply to men or to nonwhite women. But they reinforced the evidence for the health benefits of moderate drinking.

WELLINGTON, July 29 (Xinhua) -- Scientists from around the world will gather on the east coast of New Zealand next week to discuss proposals to study "silent" earthquakes by drilling into the seabed.Silent quakes, also known as slow slip events, occur on the boundaries of the earth's tectonic plates, where one plate dives under another in areas known as subduction zones, and are slower than normal quakes, taking weeks or months to occur rather than seconds, and are rarely felt on the surface.About 70 scientists from 10 countries will convene in the city of Gisborne, which lies near the site of a major fault line and where scientists first identified silent earthquakes in 2002.Slow-slip events were first discovered with the advent of new measurement technologies on the west coast of Canada about 15 years ago and have since been recorded at about a dozen locations around the world, including four sites around New Zealand, said a spokesperson for New Zealand's Institute of Geological and Nuclear Sciences (GNS Science).About eight slow-slip episodes have occurred under Gisborne since 2002 at roughly two-year intervals.Scientists have proposed numerous theories to explain the phenomenon, but testing the theories is difficult as silent quakes happen many kilometers below ground."The best way to understand the true cause of slow-slip events is to drill into and sample the area on the plate boundary fault where they are known to occur, and monitor a whole range of physical and chemical properties at the plate interface," said Laura Wallace, of GNS Science.

SAN FRANCISCO, Sept. 22 (Xinhua) -- Facebook on Thursday introduced a new feature called Open Graph, enabling users to access and share a wide range of media and lifestyle content on the social network site.According to Facebook's chief executive officer (CEO) Mark Zuckerberg, Open Graph lets users share what they are doing in Facebook-connected apps as they are doing it.These social apps focus on media apps including books, news, music, TV, movies and games, as well as lifestyle apps such as exercise, food, fashion and travel."The last five years of social networking have been about getting people signed up, and getting people connected with their lives. The next five years are going to be defined by the apps and depth of engagement," the young CEO said in a keynote speech at Facebook's f8 developer conference.Take music for example, Facebook integrates with European music streaming service Spotify. If one's Spotify account is connected to Facebook, a message will show up in the Ticker stating the song one is listening to and in the Timeline, a new design of one's profile page. The friends of the user can listen to the same song at the same time by hovering mouse over the song in Timeline or Ticker.Spotify founder and CEO Daniel Ek and movie streaming service Netflix CEO Reed Hastings also took stage as guest speakers to introduce their partnership with Facebook.Zuckerberg also introduced social news reading applications from major news organizations such as The Washington Post and Yahoo News, which allow users to access the content directly on Facebook.Earlier at the f8 conference, Timeline was unveiled as a new feature. It is a new profile design allowing users to scroll vertically through the big moments of one's life in a single page.Zuckerberg assured users that they have complete control over their Timeline, saying they can decide what content will appear and who can see it. The new feature will be available in a few weeks.Since Google launched its own social network "Google+" in June, Facebook has been in a combat mode, striving to roll out new products and features to beat the search giant. In his keynote speech on Thursday, Zuckerberg said half a billion people now use Facebook every day.Two days before the f8 conference, Google announced to open its social network to the public, noting it has introduced 100 new features in the three-month trial.
