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.

NEW YORK, April 13 (Xinhua) -- New York City Mayor Michael Bloomberg and former U.S. President Bill Clinton announced on Wednesday the merger of their environmental groups, hoping to make it the most prominent climate policy organization in the world.The new organization would combine C40, a coalition of international cities run by Bloomberg, and the Clinton Climate Initiative, a project of Clinton' s philanthropic foundation, into a single organization, which will focus on population-rich cities to address global warming."I am elated by this. I think we really have a chance to make a difference," said Bill Clinton during a press conference at Gracie Mansion, adding that "together we are proving it is possible to create jobs and grow economies through reduced emissions."C40 and the Clinton Climate Initiative both seek to cut carbon emissions through programs that reduce energy use in buildings, promote mass transit and reuse greenhouse gases emitted by landfills.The newly combined organization is said to have a budget of about 15 million U.S. dollars. The group will have main offices in New York, Los Angeles and London.

SAN FRANCISCO, April 28 (Xinhua) -- Cisco Systems Inc., world's largest maker of computer-networking equipment, on Thursday brought up an early retirement offer to its employees in the United States and Canada, in a move to cut costs and restructure the company.The voluntary plan applies to employees who are at least 50 years old and have a combined age and years of service at Cisco for at least 60 as of July 8, the company said in a memo sent to employees."Cisco employs a variety of different methods to control costs and align investment dollars, and offering this voluntary early retirement program to those eligible employees in the U.S. and Canada is part of our ongoing commitment to responsible business management," the company said in a statement.Cisco gave no details on the costs it would save and the number of employees eligible for the plan.Earlier this month, Cisco CEO John Chambers warned that "tough decisions" would be made to preserve profitability as government budget pressure has been costing the company orders and slowing its sales growth.On April 12, Cisco announced to shut down its Flip Video camcorder business to restructure its business and support its key priorities.

WELLINGTON, May 27 (Xinhua) -- Eating kiwifruit might be a much better way of getting vitamin C into your system than taking purified vitamin supplements, according to research from New Zealand.Researchers with the University of Otago found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form.The study was published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research, said a statement from the university.Lead researcher Associate Professor Margreet Vissers said people required vitamin C (ascorbate) in all body tissues and organs to be healthy, but the only source of vitamin C was through food or in purified form, arguably the most commonly consumed vitamin supplement.In the experiment vitamin C-deficient mice were fed the vitamin over a month, either as kiwifruit or as an equivalent amount of pure vitamin C, said the statement.Mice fed the kiwifruit absorbed vitamin C much more efficiently than those given the purified supplement form, and they also retained it for longer, indicating something in the fruit improved absorption and retention."The findings of the mouse trial have important implications for human nutrition," said Vissers."The question that has often been asked is whether a supplement is as good a source of vitamin C as whole foods, but few studies have addressed this issue. We are uniquely placed to do that work. "An equivalent human study was underway to determine whether the situation also applied to people, said the statement.The mouse study was funded by the university and kiwifruit marketing firm Zespri.

LOS ANGELES, April 17 (Xinhua) -- Global warming will melt all the ice in the Arctic Ocean every summer, raising earth temperatures even further, researchers at the University of California-Los Angeles (UCLA) warned.The findings, available online Sunday in the April issue of Earth and Planetary Science Letters, a leading journal in geoscience, were based on analysis of the fossilized remains of four-million-year-old mollusks, they said.Two novel geochemical techniques used to determine the temperature at which the mollusk shells were formed suggest that summertime Arctic temperatures during the early Pliocene epoch (3.5 million to 4 million years ago) may have been a staggering 18 to 28 degrees Fahrenheit warmer than today, the researchers said.And these ancient fossils, harvested from deep within the Arctic Circle, may have once lived in an environment in which the polar ice cap melted completely during the summer months, according to the researchers.Such balmy polar weather would certainly melt all the ice in the Arctic Ocean every summer, said Aradhna Tripani, an assistant professor at the UCLA's departments of Earth and space sciences."Our data from the early Pliocene, when carbon dioxide levels remained close to modern levels for thousands of years, may indicate how warm the planet will eventually become if carbon dioxide levels are stabilized at the current value of 400 parts per million," she said.The earth's temperature was raised five to nine degrees Fahrenheit merely by the absence of year-round Arctic ice, according to Tripani.The results of the study lend support to assertions made by climate modelers that summertime sea ice may be eliminated in the next 50 to 100 years, which would have far-reaching consequences for Earth's climate, she said."The Intergovernmental Panel on Climate Change identifies the early Pliocene as the best geological analog for climate change in the 21st century and beyond," said Tripati. "The climate-modeling community hopes to use the early Pliocene as a benchmark for testing models used for forecasting future climate change."
