BEIJING, June 3 (Xinhua) -- Google lacked evidence to support its accusations that Chinese hackers are behind the alleged cyber attacks on hundreds of its email accounts and the timing to make such accusations is evil-intentioned, Chinese experts said on Friday."Google's accusation is neither serious nor credible as it has not published any evidence that shows the hackers are from China," said Dai Yiqi, a cyber security expert with Tsinghua University.Eric Grosse, engineering director of Google's Security Team wrote on the company blog Wednesday that unidentified hacker attacks likely originated from the eastern Chinese city of Jinan, tried to collect user passwords of the Gmail accounts of hundreds of users, including senior U.S. government officials, Chinese "human rights activists" and journalists.A report released in 2009 by the United States-China Economic and Security Review Commission, an organization created by the U.S. Congress, claimed that Jinan is the home of a Chinese military reconnaissance office.An anonymous cyber security expert believes, despite Google not referring to the Chinese government in the latest attack claim, the company is targeting the Chinese government by listing the victims of the attacks as those whom only the Chinese government are interested in."Both their intentions and the timing of the accusation are dubious," Dai said.Google's accusation followed on the heel of the reported Pentagon's first formal cyber strategy. The Wall Street Journal reported Tuesday that the Pentagon concluded that computer sabotage coming from another country can count as an act of war and the United States may respond by using traditional military force.Li Shuisheng, a research fellow with a top military science academy of the People's Liberation Army, believes there are political motives behind Google's accusation.Google may well have attempted to instigate a new round of the cyber row between China and the United States, Li said.Wednesday's accusation by Google came more than a year after the company allegedly uncovered a cyber attack on its systems that it said it traced to China.In January, 2010, Google said it had been attacked by hackers supported by the Chinese government, and later announced to withdraw from Chinese mainland. The row ended up with Google redirecting Chinese mainland users to a site in Hong Kong.In such cyber attacks, it is easy to locate the IP address of hackers but hard to tell where the hackers actually are, said Dai."Hackers usually launch attacks by camouflaging their own IP addresses or controlling computers of others. Therefore, we can hardly tell the location of the hacker unless we have sufficient evidence," he said.China is one of the leading targets of cyber attacks. It has the world's largest number of computers infected with bot, a type of malware which allows a cyber attacker to gain control over the affected computer.About 13 percent of the world's computers infected with bot are in China."Without cooperation between governments, absolute security cannot be guaranteed in cyber community," said Li , adding only cooperation can ensure safe information exchange.

WASHINGTON, Aug. 16 (Xinhua) -- The White House announced Tuesday that the U.S. Departments of Agriculture, Energy and Navy will invest up to 510 million U.S. dollars in partnership with the private sector to facilitate the country's biofuel industry development."Biofuels are an important part of reducing America's dependence on foreign oil and creating jobs here at home," U.S. President Barack Obama said in a White House statement.The initiative is a response to a directive from Obama issued in March as part of the Blueprint for A Secure Energy Future, the administration's framework for reducing dependence on foreign oil."But supporting biofuels cannot be the role of government alone. That's why we're partnering with the private sector to speed development of next-generation biofuels that will help us continue to take steps towards energy independence and strengthen communities across our country," Obama added.The joint plan calls for the three departments to invest up to 510 million dollars in the next three years, which will require substantial cost share from private industry, in a bid to reduce U. S. reliance on foreign oil and create jobs at home."By building a national biofuels industry, we are creating construction jobs, refinery jobs and economic opportunity in rural communities throughout the country," said U.S. Agriculture Secretary Tom Vilsack.White House figures revealed that the world's largest economy spends more than 300 billion dollars on imported crude oil every year.With a slackening economic recovery and the government's approval rate at a record low level, the Obama administration is rolling out a string of measures in recent days to accelerate economic growth and job creation.

WASHINGTON, Aug. 18 (Xinhua) -- Using integrated radar observations from a consortium of international satellites, NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica, the U.S. National Aeronautics and Space Administration (NASA) announced Thursday.The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change."This is like seeing a map of all the oceans' currents for the first time. It's a game changer for glaciology," said Eric Rignot of NASA's Jet Propulsion Laboratory and the University of California (UC), Irvine. Rignot is lead author of a paper about the ice flow published online Thursday in Science Express. "We are seeing amazing flows from the heart of the continent that had never been described before."Rignot and UC Irvine scientists used billions of data points captured by European, Japanese and Canadian satellites to weed out cloud cover, solar glare and land features masking the glaciers. With the aid of NASA technology, the team painstakingly pieced together the shape and velocity of glacial formations, including the previously uncharted East Antarctica, which comprises 77 percent of the continent.Like viewing a completed jigsaw puzzle, the scientists were surprised when they stood back and took in the full picture. They discovered a new ridge splitting the 5.4-million-square-mile landmass from east to west.The team also found unnamed formations moving up to 800 feet annually across immense plains sloping toward the Antarctic Ocean and in a different manner than past models of ice migration."The map points out something fundamentally new: that ice moves by slipping along the ground it rests on," said Thomas Wagner, NASA's cryospheric program scientist in Washington. "That's critical knowledge for predicting future sea level rise. It means that if we lose ice at the coasts from the warming ocean, we open the tap to massive amounts of ice in the interior."

SAN FRANCISCO, Sept. 13 (Xinhua) -- Intel and Google on Tuesday announced a partnership to enable the world's largest chip maker's architecture on the search giant's products, saying that an Intel chip-based Android smartphone will hit the market in the first half of 2012.In a joint press release, the two companies said the future versions of Android mobile operating system will support Intel's low power Atom processors, in addition to other architectures.At the Intel Developer Forum in San Francisco on Tuesday, Intel Chief Executive Officer Paul Otellini said the Intel smartphone chip is code-named Medfield and based on the company's own PC- based computer architecture.Otellini said multiple vendors around the world will launch the Medfield-based Android smartphones in the first half of 2012.Andy Rubin, senior vice president of mobile at Google, came on stage at the close of Otellini's keynote to hail the joint initiatives between the two companies.Intel has been struggling to get a bite of the booming market of smartphones and tablets. Most of the current mobile devices use chips based on architecture from ARM Holdings, which are considered more power efficient than Intel's products. Nokia had planned to ship smartphones with Intel chips this year, but it shifted to ARM-based phones with Windows Phone 7 system.Otellini said Intel will eventually have an advantage in supplying smartphone chips as the business is not established in terms of the final winner and performance of the products keeps growing.

WASHINGTON, July 13 (Xinhua) -- Human neural stem cells are capable of helping people regain learning and memory abilities lost due to radiation treatment for brain tumors, a University of California, Irvine (UCI) study suggests.Research with rats found that stem cells transplanted two days after cranial irradiation restored cognitive function, as measured in one- and four-month assessments. In contrast, irradiated rats not treated with stem cells showed no cognitive improvement."Our findings provide solid evidence that such cells can be used to reverse radiation-induced damage of healthy tissue in the brain," said Charles Limoli, a UCI radiation oncology professor.Study results will appear Friday in Cancer Research, a journal of the American Association for Cancer Research.Radiotherapy for brain tumors is limited by how well the surrounding tissue tolerates it. Patients receiving radiation at effective levels suffer varying degrees of learning and memory loss that can adversely affect their quality of life."In almost every instance, people experience severe cognitive impairment that's progressive and debilitating," Limoli said. " Pediatric cancer patients can experience a drop of up to three IQ points per year."For the UCI study, multipotent human neural stem cells were transplanted into the brains of rats that had undergone radiation treatment. They migrated throughout the hippocampus -- a region known for the growth of new neurons -- and developed into brain cells.Researchers assessed the rats one month and four months after transplantation, noting enhanced learning and memory abilities at both intervals.Additionally, they found that transplanting as few as 100,000 human neural stem cells was sufficient to improve cognition after cranial irradiation. Of cells surviving the process, about 15 percent turned into new neurons, while another 45 percent became astrocytes and oligodendrocytes -- cells that support cerebral neurons.Most notably, Limoli said, he and his colleagues discovered that about 11 percent of the engrafted cells expressed a behaviorally induced marker of learning, indicating the functional integration of those cells into memory circuits in the hippocampus."This research suggests that stem cell therapies may one day be implemented in the clinic to provide relief to patients suffering from cognitive impairments incurred as a result of their cancer treatments," Limoli said.
