LOS ANGELES, Sept. 10 (Xinhua) -- Scientists at the University of California Los Angeles campus have announced that they have successfully used new prediction algorithms to forecast climate up to 16 months in advance.Professor Michael Ghil said in a UCLA news release Friday his team used new prediction algorithms based on matching ocean temperature records with new theories on how long-term climate trends are influenced by short-term weather extremes.That's twice as far into the future as previously accomplished.Ghil, a distinguished professor of climate dynamics in the UCLA Department of Atmospheric and Oceanic Sciences and senior author of the research, said the new prediction formulas will give climate experts and governments clues about long-term swings in the El Nino/La Nina oscillation in the Pacific Ocean, which drastically affects weather in the Americas, Asia and Australia.The new forecasting tool uses sea temperatures and has been tested on decades of historical data. The forecasts were then cross-checked against actual climate trends.The UCLA team also said that their 16-month forecasts were more accurate than previous forecasts that went only 8 months forward.Ghil emphasized that the forecasting tools are for climate, which is long-range, global patterns, but not for meteorology, which is short-term weather forecasting."Certain climate features might be predictable, although not in such detail as the temperature and whether it will rain in Los Angeles on such a day two years from now," said Ghil, who is also a member of UCLA's Institute of Geophysics and Planetary Physics. "These are averages over larger areas and longer time spans."The study is currently available online in the journal Proceedings of the National Academy of Sciences (PNAS) and will be published in an upcoming print edition of the journal.

KATHMANDU, Aug. 3 (Xinhua) -- Two glaciers in Nepal that shrank at an accelerated rate in the past 10 years compared to preceding decades will inevitably disappear from rising temperatures as no fresh snow supply is expected for them, a new research by Japan's Nagoya University says.According to Wednesday's Republica daily, the masses of the Yala glacier of Langtang Himal in central Nepal and the AX010 glacier of Shorong Himal in the Khumbu region shrank annually by 0. 8 meters and 0.81 meters respectively in the 2000s, which was a significant acceleration from the 0.68 and 0.72 meters of shrinkage per year between 1970 and 1990, said findings of the research published in a journal of the National Academy of Sciences of the United States on Tuesday."If the trend since the 1990s continues for the Yala and AX010 glaciers, the disappearance of these glaciers is inevitable because they are about to lose their accumulation areas, thus, no snow supply is expected for these glaciers," says the research conducted by Koji Fujita and Takayuki Nuimura.The researchers also found that while the shrinking of glaciers has accelerated in humid environments, the opposite is true for those in arid environments. The shrinking of Rikha Samba glacier located in the Kaligandaki Hidden Valley slowed from 0.57 meters per year between 1970 and 1990 to 0.48 meters per year in the 2000s."A comparison of the mass balance results and annual precipitation reveals that glacier wastage has been accelerated in humid environments but suppressed in an arid environment," the research says.Apart from environment, altitude also appears to play a role in the lifespan of glaciers, the researchers say. Rikha Samba is located at an altitude of 5,700 meters where loss of mass from melting could be compensated to some extent by collection of snowfall.The Yala glacier and AX010, on the other hand, are located at lower altitudes of 5,400 meters and 5,200 meters respectively.

JIANGYIN, Jiangsu, July 1 (Xinhua) -- China's manned deep-diving submersible, the Jiaolong, embarked on a journey on Friday during which it will make a 5,000-meter dive in the Pacific Ocean.During the dive, the submersible will undergo several operational tests in which it will take photos, shoot video, survey seabeds and take samples from the ocean floor, according to Jin Jiancai, deputy director of the submersible's diving test program team.The tests will be conducted in the Pacific Ocean in accordance with a contract signed between the China Ocean Mineral Resources Research & Development Association and the International Seabed Authority (ISA).The submersible is scheduled to spend 47 days at sea, according to a statement from the Ministry of Science and Technology.A submersible differs from a submarine, as it typically depends on another vessel or facility for support.The Jiaolong, designed to reach a depth of 7,000 meters, completed 17 dives in the South China Sea between May 31 and July 18 last year, reaching 3,759 meters during its deepest dive.In the year since the submersible's last dive, program team members have made several technical improvements to the submersible and its support vessel, Jin said.Jin said the program team members are "very confident" about the test.He also stressed that the test will be carried out in accordance with the provisions of the United Nations Convention on the Law of the Sea as well as the ISA's rules and regulations.The Jiaolong is the world's first manned submersible designed to reach depths of 7,000 meters below sea level, according to Xu Qinan, the submersible's chief designer.

BEIJING, Aug. 23 (Xinhuanet) -- More than 90 percent of U.S. heart attack patients who need the lifesaving procedure receive it within just 90 minutes of being admitted to the hospital, according to a study released Monday in the journal Circulation.The study on the American Heart Association's journal shows that in 2010, 91 percent of heart attack patients who needed angioplasty were treated within the 90-minute window. While in 2005, 44% were.Researchers analyzed data on more than 300,000 such patients who underwent emergency angioplasty between January of 2005 and October of 2010.The improvement is the result of a nationwide effort between federal agencies, health care organizations and health care providers to improve heart attack care and outcome, said study author Dr. Harlan M. Krumholz, a professor of medicine and epidemiology and public health at Yale University School of Medicine, according to U.S. News reports.

MOSCOW, Aug. 30 (Xinhua) -- Russia's space agency said Tuesday that a Proton-M rocket launch failed earlier this month because of a malfunction in the upper stage.The conclusion was reached by an independent investigation commission following a series of checks, Roscosmos said in a report that was posted on its website."The commission reported that the time span reserved for the gyrostabilized platform's turn was miscalculated and narrowed, which caused the Briz-M upper stage's disorientation and the satellite's journey to a wrong orbit," the agency said.Other systems in the upper stage performed well, the agency said, adding it has lifted a ban on launches of the Proton-M carrier rockets equipped with the Briz-M upper stage.Local media reported the Briz-M, manufactured by the Khrunichev State Research and Production Space Center, has had five failures over its 12-year history of operation.On Aug. 18, a Proton-M carrier rocket failed to deliver a communications satellite into orbit. After the failure, Russia suspended launches of Proton-M rockets pending the outcome of an investigation into the failure.
