BEIJING, Jan. 8 (Xinhua) -- China's central authorities have highlighted travel safety as the nation on Sunday officially kicked off the world's largest holiday migration, a time in which mass numbers of passengers will be homeward bound for the traditional Chinese Spring Festival.Safe travel has emerged as a hot-button issue facing the government as passenger trips during the 40-day travel peak are expected to hit a record high of over 3 billion.Liu Tienan, vice chief of the National Development and Reform Commission, the country's top economic planner, told the press on Sunday that passenger transport during the period is not looking good as the enormous migration outweighs existing transportation capacities.?A volunteer guides passengers to their train at Chengdu Railway Station in Chengdu, capital of southwest China's Sichuan Province, Jan. 7, 2012. Starting from Jan. 8, 2012, China's transport system will undergo a 40-day travel rush, which is characterized by a hightened passenger flow around the time of the oncoming Chinese New Year.Liu warned of the likelihood of heavy snow and icy rain that could hamper travel while vowing greater efforts to avoid another travel disaster, as was seen in early 2008 when unprecedented heavy snow and freezing rain inundated the south of the country, bringing traffic to a standstill during the peak holiday season.A total of 3.16 billion passenger trips are expected during the next 40 days, up 9.1 percent from a year earlier, of which, 235 million trips will be made via the country's railways, up 6.1 percent year-on-year.Hu Yadong, vice minister of railways, said a daily average of 5.88 million people will make train trips during the period, 340,000 more than the corresponding period in 2011.At the Beijing Railway Station on Sunday, staff members checked passengers' train tickets and ID cards, as an ID-based train ticket purchasing system kicked off nationwide at the start of the new year in an effort to curb ticket scalping.

SAN FRANCISCO, Oct. 5 (Xinhua) -- Apple co-founder and longtime Chief Executive Officer Steve Jobs passed away on Wednesday."Steve died peacefully today surrounded by his family," Jobs' family said in a statement."We are grateful for the support and kindness of those who share our feelings for Steve. We know many of you will mourn with us, and we ask that you respect our privacy during our time of grief," said the statement.Apple's website has changed to "Steve Jobs: 1955-2011," along with the most iconic picture in which the scraggly bearded charismatic visionary posed with one hand up to his chin.Photo taken on Oct. 5, 2011 shows photo of Steve Jobs on the front page of www.apple.com. Apple Board of Directors announced that co-founder and former Chief Executive Officer Steve Jobs passed away on Wednesday"Apple has lost a visionary and creative genius, and the world has lost an amazing human being," the company said in a statement. "Those of us who have been fortunate enough to know and work with Steve have lost a dear friend and an inspiring mentor. Steve leaves behind a company that only he could have built and this spirit will forever be the foundation of Apple."Apple are asking for "thoughts, memories and condolences" to be shared by emailing rememberingsteve@apple.com.Apple Board of Directors also said in a statement that "Steve's brilliance, passion and energy were the source of countless innovations that enrich and improve all of our lives. The world is immeasurably better because of Steve."According to a memo sent by CEO Tim Cook, Apple is planning a celebration of Jobs' life for employees that will take place soon.Jobs took a medical leave of absence earlier this year, the third in his battle with pancreatic cancer that began in 2004. On Aug. 24, he stepped down as Apple CEO, saying "I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple's CEO, I would be the first to let you know. Unfortunately, that day has come."Jobs recommended former CEO Tim Cook take his place as CEO. On Tuesday, Cook gave his first product announcement as CEO unveiling the new iPhone 4S.

WASHINGTON, Jan. 1 (Xinhua) -- Twin U.S. spacecraft to study the moon from crust to core put themselves into the lunar orbit on New Year's Eve and New Year's Day, the country's space agency said.The second Gravity Recovery And Interior Laboratory, or GRAIL-B, reached its lunar orbit at 5:43 p.m. EST (2243 GMT) on Sunday, according to the National Aeronautics and Space Administration (NASA).The GRAIL-A started orbiting the moon at 5 p.m. (2200 GMT) Saturday.The insertion maneuvers placed the spacecraft into a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours, NASA said.Over the coming weeks, the GRAIL team will execute a series of burns with each spacecraft to reduce their orbital period to just under two hours. At the start of the science phase in March 2012, the twin GRAILs will be in a near-polar, near-circular orbit with an altitude of about 55 km."NASA greets the new year with a new mission of exploration," Administrator Charles Bolden said in a statement. "The twin GRAIL spacecraft will vastly expand our knowledge of our moon and the evolution of our own planet."During GRAIL's science mission, the two probes will transmit radio signals precisely defining the distance between them. As they fly over areas of greater and lesser gravity caused by visible features such as mountains, craters and masses hidden beneath the lunar surface, the distance between the twin spacecraft will change slightly.Scientists will translate this information into a high-resolution map of the moon's gravitational field.The data will allow scientists to understand what goes on below the lunar surface and increase knowledge of how Earth and its rocky neighbors in the inner solar system developed into the diverse worlds we see today.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

SAN FRANCISCO, Nov. 14 (Xinhua) -- Apple on Monday released a new version of its media player program iTunes, adding the much- anticipated scan-and-match service for music iTunes Match.The feature, included in iTunes 10.5.1, can scan a user's library to find music and match the content to the music available in iTunes Store. If it finds a match, users don't need to upload the music and can listen to them anywhere, even better-quality versions, on any devices running Apple's iOS operating system. Music that doesn't match is automatically uploaded.With a subscription fee of 24.99 U.S. dollars a year, users can store up to 25,000 of their own songs in Apple's cloud server. The iTunes Match is currently only available in the United States.Subscriptions for iTunes Match are unavailable for a while Monday morning due to excessive demand.The iTunes Match was first introduced in June along with Apple' s iCloud platform, the company's cloud service enabling users to sync their files, apps and content among Apple devices.Unlike Google and Amazon, Apple got the official blessings from all four major music labels, making the company only need to keep one copy of each song in its cloud server, eliminating the uploading work for users and redundancies for servers.When Apple's late co-founder Steve Jobs introduced the feature in his last keynote address in June, he touted the feature as "an industry leading effort," saying that the 24.99-dollar price is cheaper than Amazon's offering and Google has not announced a price yet.The release is also ahead of Google's latest music push. In an email invitation sent out last Friday, the search giant said it will hold an event called "These Go To Eleven" on Wednesday in Los Angeles. Tech news website The Verge reported that it will be the debut of the company's cloud music service Google Music.
