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."

BEIJING, Sept. 5 (Xinhua) -- China and the World Bank are jointly researching ways to help rebalance the world's second largest economy and move toward a path of sustainable growth under the current challenging global economic situation, said World Bank Group President Robert B. Zoellick on Monday.A report, jointly being prepared by the World Bank, China's Ministry of Finance, and the Development Research Center of the State Council, will be released later this year to support China in identifying the many challenges and policy choices it will face in the next two decades, as the country seeks to avoid the so-called "middle-income trap," a stage of economic development that has slowed progress in many countries, Zoellick said.Regarding this autumn as "a sensitive time facing the world's major economies," Zoellick said many countries, including the United States, the European Union and Japan, were facing the similar fundamental challenge of restructuring for sustainable economic growth."Perhaps the challenge is more difficult for China as the country has already made remarkable progress, and thus it's not easy to persuade people to make a change," he said.Commenting in Beijing on a weekend workshop with senior Chinese officials and outside experts, Zoellick said there was agreement that China will have to rebalance its economy, improve the environment, reduce inequality and advance the quality of life for its people while at the same time maintaining rapid growth."In the near term, inflation is China's priority, as Premier Wen Jiabao mentioned," Zoellick said, adding that the Chinese government was moving in the right direction, though it was too early to have the problem solved.In next 10 years, however, Zoellick said he could not imagine China continuing to rely on exports for growth, especially when developed economies have had difficulties recovering.By shifting away from an over-dependence on export-led growth to a greater reliance on domestic demand and investment, China could benefit not only itself but the world economy, he said.As China's 12th Five-Year Plan has pointed the way forward with what needs to be done, Zoellick said the ongoing research will try to help with the "how."He said the report will cover issues such as how China can complete its transition to a market economy; how to promote open innovation; how to advance green development; how to deliver equality of opportunity and social security to citizens; how to strengthen the fiscal system, and how China can become a responsible stakeholder in the international system.During his stay in China, Zoellick also visited the country's wasteland-turned-grain-producing-base in the northeast, including a farm, a rice mill, an agricultural research center and a modern agricultural machinery park, and learned about how this land transformation had affected local people's lives.As the world population is expected to hit 9 billion by 2050, Zoellick said the World Bank has been urging G-20 countries to prioritize food issues."China feeds 20 percent of the world's population with less than 10 percent of the world's agricultural land and less than six percent of its water, so China could make a significant contribution to global food security," Zoellick said.

SYDNEY, July 15 (Xinhua) -- The world's first drug to increase life expectancy of people with advanced melanoma has been approved for use in Australia, local media reported on Friday.The breakthrough drug Yervoy got approval from the Therapeutics Good Association (TGA) on Friday amid hopes it could add two years to the life of people with the most lethal form of skin cancer but for whom other treatments have failed, the Australian Associated Press (AAP) said.Clearance for the drug's use in Australia follows similar approvals by the U.S. health regulator in March.Yervoy works by attacking and destroying cancer cells.Patients are hooked up to an intravenous drip once every three weeks for a total of four doses.Professor Peter Hersey, consultant immunologist to the Melanoma Institute Australia, said no other drug had improved survival rates like Yervoy."Not all patients respond to it but those who do have a good chance of living longer than they would have otherwise," Hersey told AAP.While it may improve survival rates, Yervoy can produce side effects from diarrhea and vomiting to serious blood infections and kidney failure.The average survival time for people with advanced melanoma is just six months.A global study of 676 people with melanoma found that 45 percent of patients given Yervoy were still alive after one year, according to AAP.More than 20 percent lived at least two years, with a small number managing to survive for six years.A separate study, published in June, which showed similarly improved survival rates for patients with newly diagnosed advanced melanoma, has raised hopes that Yervoy could be made more widely available.Melanoma is the fourth most common cancer in Australia, with 10, 300 people diagnosed each year.

CAIRO, July 4 (Xinhua) -- U.S. and Italian archeologists have discovered the oldest description about an Egyptian king (about 3, 200 BC) in Egypt's Aswan, Egyptian Antiquities Minister Zahi Hawass said on Monday.The engravings "traces back to when the Egyptian language firstly recorded in hieroglyphs and tells about a unique complete royal ceremony which was known in the ancient Egyptian era," said Hawass in a statement."The pharaoh appears to be wearing the Upper Egypt crown accompanied by (Horus apostles) at the royal court, " Hawass added.Horus is one of the oldest and most significant deities in the ancient Egyptian religion and was worshipped from at least the late Predynastic period through to Greco-Roman times."This discovery is considered a supplementary one at the site unearthed near in el-Hamdulab site in northern Aswan, archaeologists said.This is one of the latest discoveries in Egypt as the surrounding wall of Betah temple (1550 BC-1070 BC) and a gate traces back to Shabaka king era were unearthed on Saturday in Luxor.

JERUSALEM, July 25 (Xinhua) -- A new study carried out by a Tel Aviv University researcher indicates that the common backache may not only be caused by bad positions or aging, but also by your genes.Prof. Gregory Livshits of the Sackler Faculty of Medicine says that genes play a major role in back pain, especially in the lower back, and in spinal deterioration.In a decade-long project with 2,500 identical and non-identical twins, Livshits found that, in one Arab family, the same back problems appeared in all the members of the family, whether young or old.According to the study, non-identical twins were three times more likely to have back pain, while identical twins were six times more likely to have the same back problems.Livshits believes the discovery of the link between back pains and genes could lead to much better treatment.The research was developed in collaboration with a team of scientists at Kings College, London, led by Prof. Tim Spector and Dr. Fran Williams and was recently published in the journal " Annals of the Rheumatic Diseases."In order to better investigate the genetic causes for one of the world most common pains, Livshits and his colleagues hope to put together an international consortium of research groups.
