BEIJING, Feb. 2, (Xinhua) -- All Chinese travelers stranded in Egypt are expected to have been returned to China by Thursday, the start of the Spring Festival, said China's national tourism authorities late Wednesday.As of the Spring Festival Eve, most of the Chinese tourists stranded in Egypt due to the country's nation-wide protests had been flown back to China by chartered planes, according to a statement released by the National Holiday Office, an inter-ministerial agency led by the National Tourism Administration.China had sent a total of eight "special commercial flights" to Cairo, Luxor and Hurghada to bring back Chinese citizens stranded in these cities, and six of the planes had returned, carrying 1,371 people, including those from Hong Kong, according to the Chinese Foreign Ministry.The Spring Festival is the Chinese lunar New Year, a time for family reunions, according to Chinese tradition.The National Holiday Office has also issued warnings about traveling to Australia, as tropical cyclone Yasi was expected to make landfall in northeast Queensland late Wednesday local time.

WASHINGTON, April 29 (Xinhua) -- A U.S. appeals court ruled on Friday that the Obama administration can continue the taxpayer- funding for human embryonic stem cell research.The U.S. Court of Appeals in Washington overturned a preliminary federal court order that would have blocked the U.S. Health and Human Services Department and the National Institutes of Health (NIH) from spending government money on embryonic stem cells research."Today's ruling is a victory for our scientists and patients around the world who stand to benefit from the groundbreaking medical research they're pursuing," said Nicholas Papas, a White House spokesman.U.S. President Barack Obama has been trying to expand government funding for human embryonic stem cells research, saying that years of progress on finding cures for spinal cord injuries, Parkinson's disease and other diseases would be lost without the government support on this field.Opponents have been arguing the research is unacceptable because embryonic stem cells can only be obtained through destroying human embryos.Last August, a federal judge ruled that the government-backed embryonic stem cell research violated the law because embryos were destroyed in the process and it jeopardized the position of researchers using adult stem cells for winning federal grants.The government immediately appealed to the ruling, and the appeals court said the research could continue at the NIH before the judge ruled on the case.

LOS ANGELES, April 18 (Xinhua) -- Sugarcane has the effect of cooling temperatures, thus playing role in stemming global warming, a new study has found.Sugarcane does so by reflecting sunlight back into space and by lowering the temperature of the surrounding air as the plants " exhale" cooler water, according to the study conducted by researchers at the Carnegie Institution's Department of Global Ecology.The researchers used data from hundreds of satellite images over 733,000 square miles (about 1,173 square kilometers) in Brazil, where sugarcane is widely grown. They measured temperature, reflectivity (also called albedo), and evapotranspiration -- the water loss from the soil and from plants as they exhale water vapor.The findings showed that expansion of sugarcane in areas previously occupied by other Brazilian crops cools the local climate.Converting from natural vegetation to crop/pasture on average warmed the cerrado by 2.79 Fahrenheit (1.55 Centigrade, but that subsequent conversion to sugarcane, on average, cooled the surrounding air by 1.67 Fahrenheit (0.93 Centigrade), the researchers said in the study published in the April issue of Nature Climate Change."We found that shifting from natural vegetation to crops or pasture results in local warming because the plants give off less beneficial water. But the bamboo-like sugarcane is more reflective and gives off more water -- much like the natural vegetation," said lead researcher Scott Loarie. "It's a potential win-win for the climate -- using sugarcane to power vehicles reduces carbon emissions, while growing it lowers the local air temperature."Brazilians are world leaders in using biofuels for gasoline. About a quarter of their automobile fuel consumption comes from sugarcane, which significantly reduces carbon dioxide emissions that otherwise would be emitted from using gasoline.The researchers emphasized that the beneficial effects are contingent on the fact sugarcane is grown on areas previously occupied by crops or pastureland, and not in areas converted from natural vegetation. It is also important that other crops and pastureland do not move to natural vegetation areas, which would contribute to deforestation.So far most of the thinking about ecosystem effects on climate considers only impacts from greenhouse gas emissions. But according to co-researcher Greg Asner, "It's becoming increasingly clear that direct climate effects on local climate from land-use decisions constitute significant impacts that need to be considered core elements of human-caused climate change."

HOUSTON, April 15 (Xinhua) -- A major contractor for the U.S. space shuttle on Friday announced plans to lay off about 50 percent of its employees this summer after NASA retires the orbiter fleet.The contractor, Houston-based United Space Alliance, said it will cut 2,600 to 2,800 jobs, including 1,850 to 1,950 employees in Florida, 750 to 800 employees in Texas, and 30 to 40 employees in Alabama, "due to the completion of tasks related to day-to-day operations of the Shuttle fleet."The cuts will be made in late July and early August after NASA completes the final flight of Endeavour, scheduled for April 29, and the flight of Atlantis on June 28."The accomplishments of this team are unmatched in human spaceflight," Virginia Barnes, the company's president, said in a news release. "It will be difficult to say goodbye to such tremendously talented and dedicated teammates, and we are committed to making this transition as smooth as possible for them."United Space Alliance has approximately 5,600 employees working at sites in Texas, Florida and Alabama, according to the the news release.

Google chairman Eric Schmidt has promised that the firm will simplify the process by which Android phone users agree to share their data.It follows questions in the US Senate about how much location information is stored by mobile handsets.Speaking in the UK at a conference on privacy, he also revealed that Google plans to offer web users more control over their online profile.Mr Schmidt insisted that the company took the matter "very seriously".He told attendees at the Big Tent debate in Hertfordshire that his firm was working on "a series of projects" aimed at increasing transparency.Those include a revised Google Dashboard, where users can see what data they have shared with the search giant."It is worth stressing that we can only do this with data you have shared with Google. We can't be a vacuum-cleaner for the whole internet," he said.Mr Schmidt stressed that Google was on the side of consumers when it came to privacy. "In general we take the position that you own your data and should be able to opt in or out of a service," he said.But he added that if users gave consent for sharing data, it would help Google improve its services."If you choose to give us that information we can do a better job. If we know a little bit more about you we can offer better targeted search," he explained.Super injunctions revealed A recent hearing in the US Senate quizzed Google on the amount of data stored on Android handsets. The company argued that it allows people to opt out of location-based services.But Mr Schmidt conceded that the terms and conditions whereby users sign up to services needs to be simplified. "We intent to do that," he said.He predicted that such services would be more heavily regulated in the future.During a lively debate on the issue of privacy, it was revealed to the Big Tent audience, alongside several names of current super-injunction holders, that more data has been collected in the last seven years than in the whole of previous human history.
