TOKYO, Sept. 23 (Xinhua) -- Japan's H-2A rocket carrying a new information gathering satellite was launched at the Tanegashima Space Center in Kagoshima Prefecture on Friday, local media reported.Japan has already introduced three information-gathering satellites in the wake of a missile launch by Democratic People's Republic of Korea, and the latest one will replace the No. 2 satellite which has passed its use-by date, Kydo News said.Japan's H-2A rocket lifts off from the launchiung pad at the Tanegashima space centre in Kagoshima prefecture, Japan's southern island of Kyushu on September 23, 2011. Japan launched a new spy satellite into orbit September 23, officials saidThe development cost of the fourth satellite has reached 35.9 billion yen and its launch expenses have come to 10.4 billion yen, according to the government.The Japan Aerospace Exploration Agency and Mitsubishi Heavy Industries Ltd. were forced to put off the launch three times during the past four weeks due to the approach of a powerful typhoon and discovery of a system glitch. The rocket was initially scheduled to be sent into orbit on Aug. 28.

BEIJING, July 26 (Xinhuanet) -- Hong Kong scientists announced that they had determined the idea of time travel is impossible by proving nothing can travel faster than the speed of light.The finding is contained in a study done by a research team from Hong Kong University of Science and Technology. The study was published Monday in a scientific journal "Physical Review Letters" in the United States."The study, which showed that single photons also obey the speed limit c, confirms Einstein's causality, that is, an effect cannot occur before its cause," the university said on its website."By showing that single photons cannot travel faster than the speed of light, our results bring a closure to the debate on the true speed of information carried by a single photon." said Professor Du Shengwang, who led the study.The possibility of time travel was raised 10 years ago when scientists discovered the optical pulses in some specific medium might propagate information in a faster-than-light speed."Our findings will also likely have potential applications by giving scientists a better picture on the transmission of quantum information." Du said.

CANBERRA, Sept. 7 (Xinhua) -- A team of Australian and U.S. scientists on Wednesday said they discovered a genetic defect, which can lead to Leigh syndrome, a rare disorder which affects the central nervous syndrome.The scientists tested more than 1000 genes by encoding proteins active in two individuals who suffer from the illness. They used a new technique known as next-generation DNA sequencing to examine the genes.The gene they discovered encodes an enzyme which is found in the mitochondria which are subsets of cells. Without this enzyme the mitochondria do not translate proteins efficiently, and this then causes Leigh syndrome.According to David Thorburn, from the Murdoch Children's Research Institute in Melbourne, the discovery shows the enormous potential of the new technology."These findings demonstrate the ability of sequencing technologies to improve diagnosis," Professor Thorburn said in a statement released on Wednesday."Although it isn't clear in the case of Leigh syndrome whether the precise molecular diagnosis will necessarily lead to therapies, the current findings represent a meaningful service."He added that diagnosis of the disease along with its specific genetic cause can also be informative about the risk a couple has of having another affected child. The diagnostic information can help in decisions about whether and how to pursue alternative means of having children, for instance through the use of donor sperm or eggs.The research team consisted of scientists from Australia's Murdoch Institute as well as the Broad Institute in the U.S.In Leigh syndrome, infants are born apparently healthy only to develop movement and breathing disorders that worsen over time, often leading to death by the age of three. The problem is that the mitochondria responsible for powering their cells cannot keep up with the demand for energy in their developing brains.

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."

BERLIN, Aug. 28 (Xinhua) -- Mercedes-Benz, the world leading luxury car producer, celebrates the 125th anniversary of its invention of automobile with what it claimed the largest gathering ever, at the former Tempelhof airport in Berlin on the weekend.The Mercedes-Benz Club and Mercedes-Benz enthusiasts greet visitors with some 1,800 well-assorted Mercedes-Benz-branded vehicles, ranging from vintage and classic passenger cars to a variety of historic commercial vehicles, on a vast open areas of 250,000 square metres of the abandoned Tempelhof airport, which was closed in 2008.It took Mr. Lauritzen and his wife two days' drive of their cherised wecker of Mercedes-Benz Cabriolet B. 320.W 142.-3,4l to reach here for taking part in the pageant."It is a long journey, but we are happy to be here to see more class cars and more friends with same interests," Mrs Lauritzen said.Owners take the opportunity to present their lovingly cared-for vehicles, which include a number of truly rare items of automotive history, to the Berlin public.The couple of Mr. Kerner drove their red Mercedes-Benz 170Dba, a made-in-1952 model with a range of special and unique designs which are very rarely seen now, over journey of 155 km from Bitterfeld to join in the gala."I'm fond of driving my classic car of Benz," said Mrs Kerner, despite it can run maximally at a speed of 50 to 80 km per hour, "but I truly enjoy the diesel engine sounds and the historic feeling it evokes."The legendary Silver Arrows, dating from the 1930s and 1950s, are also presented from the Mercedes-Benz Classic collection for demonstration drives."The brilliant history of the Silver Arrows will be brought to life with a demonstration of their impressive engine sound and incredible driving dynamics," said Michael Bock, head of Mercedes-Benz Classic and Director of Mercedes-Benz Museum GmbH."It is not often that these racing cars are driven in public, so this will be a true highlight of the program of events in Tempelhof."During the grand show, visitors are also accessible to first-hand experiences of the latest technologies applicable in the future for in passenger cars, commercial vehicles and racing cars."Some 125 years ago, Carl Benz submitted his patent application for the Benz Patent Motor Car to the Patent Office in Berlin", the organizer appealed to the visitors, saying now Mercedes-Benz is returning to Berlin to celebrate together with Berliners.
