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."

BEIJING, Jan. 26 (Xinhua) -- China remained a major victim of trade protectionism during the past year, witnessing 64 trade disputes in this period, covering some 7 billion U.S. dollars in value, China's Vice Commerce Minister, Zhong Shan, said here Wednesday.The country faced trade disputes with both developed countries and developing ones, which came from not only traditional sectors but also high-tech industries, he told a national conference on trade promotion.For the short- and mid-term, China would work to maintain a stable growth in foreign trade and keep the growth rate higher than both the global level and China's economic growth, he said.China would also strive to achieve a more balanced trade structure by boosting imports and outbound investment, to strengthen the quality and efficiency of foreign trade, he added.China's foreign trade last year jumped 34.7 percent year on year to more than 2.97 trillion U.S. dollars, while its trade surplus fell 6.4 percent to 183.1 billion U.S. dollars.

YANGON, May 6 (Xinhua) -- A five-day Myanmar traditional medicine exhibition is underway in Myanmar's former capital of Yangon beginning Thursday, aimed at promoting the development of the country's traditional medicines and disseminating medical knowledge to the public.With over 120 booths, traditional medicine producing companies are displaying their traditional medicine products and producing accessories as well as giving traditional treating service and medical education talks.As the Myanmar traditional medicine is playing a more and more important role in treating diseases in the country, the government urges traditional medicine practitioners to protect and preserve them from depletion and extinction and to ensure their perpetual existence.Myanmar is conducting research on treatment of major diseases -- diabetes, hypertension, malaria, tuberculosis, diarrhea and dysentery through traditional medicine.To do research more effectively and on a wider scale to have the Myanmar traditional medicine standardized, the country holds traditional medicine practitioners conference every year to introduce the country's traditional medicines and its medical practices and the last conference, which was the 11th, took place in Nay Pyi Taw in December 2010.At the same time, the practitioners are also urged to strive for the promotion of the standard of Myanmar traditional medicine to reach international level.

SAN FRANCISCO, April 7 (Xinhua) -- Google's Android will become the most popular smartphone operating system worldwide and will account for 49 percent of the market by 2012, IT research and advisory firm Gartner said Thursday.According to Gartner's projections, worldwide smartphone sales will reach 468 million units in 2011, a 57.7 percent increase from 2010.The company predicts that Apple's iOS will remain the second biggest platform worldwide through 2014 although its share will decrease slightly after 2011, on the assumption that "Apple will be interested in maintaining margins rather than pursuing market share by changing its pricing strategy."Microsoft's Windows, driven by its partnership with Nokia, is expected to move into the mid-tier by the end of 2012 and become the third largest in the worldwide ranking by 2013.Some analysts raised doubts on Gartner's forecasts, saying that its assumption on Apple's price strategy contradicts statements by Apple's chief operating officer Tim Cook and the cooperation between Nokia and Microsoft will not have that much of an impact on smartphone market share by 2012.

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.
