BEIJING, April 19 (Xinhuanet) -- The case in the Hollywood blockbuster "The Social Network" continues in real life.Twins Cameron and Tyler Winklevoss on Monday filed another appeal against their Harvard classmate and Facebook founder Mark Zuckerberg.The Winklevosses claim that the case needs to be reviewed by a special 11-judge panel in the latest appeal, after a three-judge panel of the 9th U.S. Circuit Court of Appeals ruled against the brothers last week.The twins initially claimed that Zuckerberg had stolen their idea for the website but agreed to drop their lawsuit in 2008 in exchange for 20 million dollars in cash and stock in the company.But later they discovered the stock was worth less than claimed at the time and sought to have the deal voided, the brothers said.

WASHINGTON, March 24 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Thursday approved the use of Zostavax, a live attenuated virus vaccine, for the prevention of shingles in individuals 50 to 59 years of age. Zostavax is already approved for use in individuals 60 years of age and older.In the United States shingles affects approximately 200,000 healthy people between the ages of 50 and 59, per year. It is a disease caused by the varicella-zoster virus, which is a virus in the herpes family and the same virus that causes chickenpox.After an attack of chickenpox, the virus lies dormant in certain nerves in the body. For reasons that are not fully understood, the virus can reappear in the form of shingles, more commonly in people with weakened immune systems and with aging."The likelihood of shingles increases with age. The availability of Zostavax to a younger age group provides an additional opportunity to prevent this often painful and debilitating disease" said Karen Midthun, director of FDA's Center for Biologics Evaluation and Research, in a statement. ( Shingles is characterized by a rash of blisters, which generally develop in a band on one side of the body and can cause severe pain that may last for weeks, and in some people, for months or years after the episode.Approval was based on a multicenter study conducted in the United States and four other countries in approximately 22,000 people who were 50-59 years of age. Half received Zostavax and half received a placebo. Study participants were then monitored for at least one year to see if they developed shingles. Compared with placebo, Zostavax reduced the risk of developing shingles by approximately 70 percent.The most common side effects observed in the study were redness, pain and swelling at the site of injection, and headache, according to the FDA.Zostavax, manufactured by Merck & Co., was originally approved on May 26, 2006, for the prevention of shingles in individuals 60 years of age and older.

You can think of NASA's Discovery program as a sort of outer-space American Idol: every few years the agency invites scientists to propose unmanned planetary missions. The projects have to address some sort of fundamental science question, and (this is the tough part) they have to be relatively cheap to pull off — say, half a billion dollars or so. Then the proposals go through a grueling competition before judges who aren't as nasty as Simon Cowell but who are every bit as tough. The one left standing at the end gets the equivalent of a recording contract: NASA supplies the funding and the launch vehicle, and away the winner goes — to orbit Mercury, as the Messenger spacecraft is doing right now; or to rendezvous with a couple of asteroids, as the Dawn mission will start doing this July; or to smash into a comet on purpose, a feat achieved by Deep Impact in 2005, a mission not to be confused with the movie of the same name. Now it's time for the next contenders. NASA has just announced that the first round of the latest Discovery competition is over, with three entries out of 28 moving on to the finals. They are, in increasing distance from Earth: the Geophysical Monitoring Station (GEMS) lander, which would use seismometers to study the interior of Mars; the Comet Hopper, which would do just that, leaping from place to place across the surface of Comet 46P/Wirtanen to see how different parts of the tumbling body react to heating by the sun; and the Titan Mare Explorer (TiME), which would plop into a sea of liquid hydrocarbons on Saturn's moon Titan — the first oceangoing vessel ever to set sail on another world. If you had to come up with a theme that ties all three missions together, it would be "origins." The Titan explorer, for example, will be studying a place that — in a crude way, at least — resembles the early planet Earth at a time when life arose here. Titan, with a thick atmosphere and a bizarro-world form of weather featuring toxic winds and hydrocarbon rain, is home to a mix of complex chemistry, complete with organic molecules. The oceans provide a medium in which the molecules can move around and interact with each other. It's even conceivable, though clearly a long shot, that some form of microscopic life already exists on this frigid moon. The Mars lander, by contrast, would visit a place where the seas — plain water in this case — vanished long ago. But the mission of GEMS goes far deeper than that. By analyzing Marsquakes on the Red Planet, GEMS will try to get a handle on what the interior of Mars is like. Scientists don't currently know whether the planet's core is liquid, like Earth's, or solid, or some mushy consistency in between. It all depends on how efficiently Mars has cooled since it formed 4.5 billion years ago, and that depends in turn on the planet's internal structure. "That's the mission," says Bruce Banerdt, of NASA's Jet Propulsion Laboratory, the lead scientist for GEMS. "We want to understand how Mars was built." Along with sensitive seismographic equipment, GEMS will drill down about 20 ft. (6 m) with a thermometer-equipped probe, trying to figure out how quickly the temperature rises with depth. "That will let us extrapolate all the way down to the center," Banerdt says, "which will tell us how fast Mars is cooling."

LOS ANGELES, April 7 (Xinhua) -- Unrecycled energy-efficient bulbs release tons of mercury into the environment every year, raising an environmental concern, it was reported on Thursday.Demand for the energy-efficient lights -- the compact fluorescent light bulb (CFL) -- is growing as government mandates for energy-efficient lighting take effect, yet only about two percent of residential consumers and one-third of businesses recycle the new bulbs, the Los Angeles Times said, quoting the Association of Lighting and Mercury Recyclers (ALMR).Each CFL contains up to five milligrams of mercury, a potent neurotoxin that's on the worst-offending list of environmental contaminants, the report said.As a result, U.S. landfills are releasing more than four tons of mercury annually into the atmosphere and storm water runoff, the Journal of the Air and Waste Management Association said in a study published by the paper.The federal Clean Energy Act of 2007 established energy- efficiency standards for light bulbs that dimmed the future for old-fashioned incandescents, which don't meet those standards. Incandescents are to be phased out by 2014 in the U.S., and California passed even stricter rules, calling for store shelves to be cleared of them by 2013.The old-style bulbs are just too wasteful, converting to light only 10 percent of the energy they consume. The rest is squandered as heat.Sales of energy-efficient alternatives like CFLs, halogen bulbs and LEDs have been growing steadily, with the low-cost CFLs the biggest sellers, according to the paper.If every California household replaced five incandescent bulbs with CFLs, the move would save 6.18 billion kilowatt-hours and prevent the annual release of 2.26 million tons of heat-trapping carbon dioxide, according to the California Energy Commission. That 's equivalent to taking 414,000 cars off the road.But no federal law mandates recycling of household fluorescent lights. Federal rules exempt some businesses, based in part on the number of bulbs used, said Paul Abernathy, executive director of the ALMR, which is based in Napa, Calif.Several states, including California, Massachusetts, Maine, Vermont and Minnesota, do require that all households and businesses recycle fluorescents, the paper said.But the ALMR said compliance is low because of a lack of convenient drop-off options.
