STOCKHOLM, Aug. 30 (Xinhua) -- Meat diet, a dietary habit popular in some developed countries, can produce more greenhouse gas and thus is likely to actually cause more impact on climate, said a Swedish study published Tuesday.According to Swedish Radio's Ekot news program, the meat diet, also known as Low Carb High Fat (LCHF) diet, doubled the greenhouse gas emission compared with the balanced diet recommended by the Swedish Food Administration.Many Swedish people have abandoned the diet habit of eating root vegetables and fruits, and switched to LCHF diets. The LCHF diet has more meat, fat and unusual greenhouse gas emission. But these root vegetables, such as potatoes and carrots, and other naturally grown vegetables can be planted with less greenhouse gas emission.The report also revealed that many of the LCHF diet advices are actually given by the researchers sponsored by meat industry.

BEIJING, June 7 (Xinhuanet) -- Sony Corp. on Monday unveiled its next generation portable gaming device, PlayStation Vita.The new PlayStation Vita will go on sale for 249 U.S. dollars, or 299 dollars for a 3G mobile version, starting in the holiday season, the Japanese electronics giant's No. 2 executive Kazuo Hirai told reporters on the eve of the E3 games convention.The device will allow gamers to be connected with one another over cellphone networks and Wi-Fi hotspots, and use GPS location-tracking technology. In the U.S., Sony is partnering exclusively with AT&T Inc. for cellphone service.Company executives have called the device Sony's biggest product launch since the PlayStation 3 five years ago."PlayStation Vita will revolutionize the portable entertainment experience," said Hirai. "The whole world is really in play."The handheld has front and back cameras, a touchscreen in front, a touch pad on the back and two knob-like joysticks. It will enable gamers to play against people using PlayStation 3 consoles over the Internet-based PlayStation Network.

WASHINGTON, Aug. 2 (Xinhua) -- The weakness of aging is associated with leaky calcium channels inside muscle cells and a drug already in Phase II clinical trials for the treatment of heart failure might plug those leaks, according to a report published Tuesday in the online edition of Cell Metabolism.Earlier studies by the research team led by Andrew Marks of Columbia University showed the same leaks underlie the weakness and fatigue that come with heart failure and Duchenne muscular dystrophy."It's interesting, normal people essentially acquire a form of muscular dystrophy with age," Marks said. "The basis for muscle weakness is the same." Extreme exercise like that done by marathon runners also springs the same sort of leaks, he added, but in that case damaged muscles return to normal after a few days of rest. A microscopic view shows smooth muscle cells derived from human embryonic stem cells showing the nuclei (blue) and proteins of the cytoskeleton (green) in this handout photo released to Reuters by the California Institute for Regenerative Medicine, March 9, 2009The leaks occur in a calcium release channel called ryanodine receptor 1 (RyR1) that is required for muscles to contract. Under conditions of stress, those channels are chemically modified and lose a stabilizing subunit known as calstabin1.Calcium inside of muscle cells is usually kept contained. When it is allowed to leak out into the cell that calcium itself is toxic, turning on an enzyme that chews up muscle cells. Once the leak starts, it's a vicious cycle. The calcium leak raises levels of damaging reactive oxygen species, which oxidize RyR1 and worsen the leak.The researchers made their discovery by studying the skeletal muscles of young and old mice. They also showed that 6-month-old mice carrying a mutation that made their RyR1 channels leaky showed the same muscular defects and weakness characteristic of older mice.When older mice were treated with a drug known as S107, the calcium leak in their muscles slowed and the animals voluntarily showed about a 50 percent increase in the amount of time spent wheel running. Now in clinical trials for patients with heart failure, the drug is known to work by restoring the connection between costabilin and RyR1.Despite considerable effort to understand and reverse age- related muscle wasting, there are no established treatments available. The new work suggests there may be hope in approaching the problem from a different angle."Most research has focused on making more muscle mass," Marks said. "What's different here is that we are focused not on muscle mass but on muscle function. More muscle doesn't help if it is not functional."

BEIJING, Aug. 12 (Xinhuanet) -- A Connecticut woman who was savagely attacked by a pet chimpanzee and had her face deformed in 2009 was shown on TV with a new face Thursday.TV pictures revealed Charla Nash’s new nose, lips and eyelid, which were transplanted in May by doctors at the Brigham and Women’s Hospital in Boston.Nash said to the viewers that she can move her mouth, smile and smell. Her daughter Brianna added that her mother can even talk and eat better now.Dr. Bohdan Pomanhac led a 30-member surgical team to complete the face transplant in 20 hours. The team also transplanted two hands but these were later removed due to blood flow problem when Nash suffered pneumonia.Nash’s friend Sandra Herold owned a 15-year-old chimpanzee named Travis that attacked without any provocation when Nash was visiting Herold.Travis simply went berserk and could not be stopped even after Herold stabbed it with a kitchen knife. It would only let go of Nash after the police arrived and shot it dead.

SAN FRANCISCO, June 23 (Xinhua) -- Facebook announced Thursday that Netflix CEO and Chairman Reed Hastings has joined the social network company's board of directors.Hastings, who successfully managed Netflix through an IPO in 2002, is expected to provide useful guidance for Facebook which plans to go public.As the most popular subscription-based movie and television show rental service in the United States, Netflix could also help Facebook figure out how to enter the business of music streaming and movies, which, CEO Mark Zuckerberg said at the eG8 Forum held in Paris last month, would be Facebook's next focus.The Facebook board seat could also help Netflix to catch up with the social evolution of the Internet with its 23.6 million subscribers in the U.S. and Canada."Reed is an entrepreneur and technologist who has led Netflix to transform the way people watch movies and TV," said Zuckerberg in a statement. "He has built a culture of continuous rapid innovation, something we share and work hard to build every day.""Facebook is propelling a fundamental change in how people connect with each other and share all kinds of content," said Hastings. "I'm looking forward to working with Mark and the rest of the board to help Facebook take advantage of all the opportunities ahead."
