OTTAWA, Oct. 3 (Xinhua) -- Many friends and colleagues of Canadian scientist Ralph Steinman reacted with shock when they learned on Monday that Steinman won the Nobel Prize for Medicine and Physiology three days after he died.Since 1974, Nobel Prizes are no longer awarded posthumously, but the Nobel Prize committee said that it had made its choice before Steinman's death.Many of Steinman's friends and colleagues said that they learned of Steinman's death at the same time that they learned of his Nobel Prize, which was awarded for a discovery Steinman made in 1973.Steinman, 68, discovered dendritic cells, which help regulate adaptive immunity, which purges invading microorganisms from the body. Dendritic cells activate T cells, which "remember" the DNA sequence of invading organisms and protect the body from later infections from the same disease."Their work has opened up new avenues for the development of prevention and therapy against infections, cancer and inflammatory disease," the citation said.Monday, the Nobel Committee defended its decision to award the prize to Steinman. "The decision to award the Nobel Prize to Ralph Steinman was made in good faith, based on the assumption that the Nobel Laureate was alive," the foundation said in a statement."The Nobel Foundation thus believes that what has occurred is more reminiscent of the example in the statutes concerning a person who has been named as a Nobel Laureate and has died before the actual Nobel Prize Award Ceremony."It is still unclear who will pick up Steinman's prize at the award ceremony later this year.Steinman, a cell biologist at Rockefeller University in New York City, died of pancreatic cancer on Friday. For more than four years, he had used his own immune therapy discoveries to extend his life."The news is bittersweet, as we also learned this morning from Ralph's family that he passed a few days ago," Rockefeller University President Marc Tessier-Lavigne said in a statement."We are all so touched that our father's many years of hard work are being recognized with a Nobel Prize," Steinman's daughter, Alexis, said in the statement. "He devoted his life to his work and his family, and he would be truly honored."Steinman's heirs will share the 1.5-million U.S. dollar prize with American genetics professor Bruce Beutler and French scientist Jules Hoffmann.Dr. Beutler is professor of genetics and immunology at The Scripps Research Institute in La Jolla, California. Dr. Hoffmann headed a research laboratory in Strasbourg, France, between 1974 and 2009 and served as president of the French National Academy of Sciences between 2007 and 2008."Ralph worked right up until last week," said Michel Nussenzweig, a collaborator of Steinman's at Rockefeller University. "His dream was to use his discovery to cure cancer and infectious diseases like HIV and tuberculosis. It's a dream that's pretty close."Steinman was born in 1943 in Montreal, Canada's second largest city, and studied chemistry and biology at McGill University in his hometown before receiving an MD from Harvard Medical School in Boston in 1968. He joined Rockefeller University in 1970 as a postdoctoral fellow."He was diagnosed with pancreatic cancer four years ago, and his life was extended using a dendritic-cell based immunotherapy of his own design," the university said in a statement.In a statement, Canadian Prime Minister Stephen Harper lauded the three winners of the Nobel for medicine and called the award " a fitting final tribute" to Steinman's life's work."Dr. Steinman shall be honored for all time with this achievement," Harper said. "Canadians will mourn his loss."

SAN FRANCISCO, Dec. 2 (Xinhua) -- Only two weeks after its shipment, Amazon's Kindle Fire has already shown the momentum to grab the second place in global tablet computer market, research firm IHS predicted on Friday.Amazon is expected to ship 3.9 million Kindle Fire tablets during the last three months of 2011, the first quarter the product goes on sale, according to preliminary projection from IHS.The number will give Amazon a 13.8-percent share of global tablet market in the fourth quarter, surpassing the 4.8 percent held by No. 3 player Samsung, and second only to Apple's commanding 65.6 percent market share."Nearly two years after Apple Inc. rolled out the iPad, a competitor has finally developed an alternative which looks like it might have enough of Apple's secret sauce to succeed," Rhoda Alexander, senior manager of tablet and monitor research for IHS, said in a statement."Initial market response strongly suggests that Amazon, with the Kindle Fire, has found the right combination of savvy pricing, astute marketing, accessible content and an appropriate business model, positioning the Kindle Fire to appeal to a brand-new set of media tablet buyers," she added.IHS analysts noted that with a price tag of 199 U.S. dollars, the Kindle Fire has set a new bar for pricing, bringing the tablet within reach of a larger portion of the buying public.IHS expects Kindle Fire's rapid ascent to help fuel the expansion of the entire tablet market, now predicting that 64.7 million tablets will be shipped in 2011, higher than its previous forecast of 60 million issued in August.The total tablet shipment number this year will represent a 273- percent growth from 17.4 million units in 2010, said IHS, which has also increased its longer-term projection of global tablet shipment in 2015 to 287.2 million units.

BEIJING, Jan. 23 (Xinhua) -- Nearly 200,000 local residents and tourists visited parks in Beijing on Monday as a series of celebrations were hosted to mark the first day of the Chinese lunar New Year, the city's park administration said.Festive activities kicked off at Beijing's famous parks, including the Temple of Heaven, the Summer Palace, and the Beihai Park, on Monday to welcome the Year of the Dragon, said Chen Zhiqiang, spokesman for the Beijing Municipal Administration Center of Parks.At the Temple of Heaven, 320 costumed performers on Monday staged a show presenting the royal heaven worship ceremony in the Qing Dynasty (1644-1911).In the one-hour ceremony, thousands of visitors watched as the royal parade marched toward the altar where the "emperor" held a ritual to pray for peace and good harvest in the coming year.At the Summer Palace, the ancient royal garden, a traditional fair opened to public with old-fashioned shops and stands selling items and snacks popular in the old days.The Chinese New Year, which begins on Monday this year, is an important occasion for family dinners, fireworks, and a trip to temple fairs.To cope with the increase in visitors, authorities in Beijing said they have deployed seven police choppers and 910,000 order-maintaining personnel across the city to prevent the breakout of fires and stampedes.

BEIJING, Jan. 7 (Xinhua) -- China's financial system is running on a stable course despite the global financial crisis. However, apparent problems and potential risks still linger, as the crisis has not ended, Premier Wen Jiabao said.Wen made the remarks at the two-day National Financial Work Conference that concluded Saturday. The meeting, held every five years, mapped out development plans for the financial sector in the upcoming five years. Similar meetings were held in 1997, 2002 and 2007."China's economy has maintained stable and relatively fast growth with stabilized consumer prices and improvements in people's lives. The financial system is running steadily. The good momentum of economic and social development remains unchanged," Wen said.Chinese Premier Wen Jiabao ( front) attends the National Financial Work Conference in Beijing, Jan. 7, 2012."We have the confidence, capabilities and conditions to move economic development to a new stage," he said.China has resolutely pushed forward a series of financial reforms which have set significant historical milestones. Large commercial banks have remarkably improved their capabilities of guarding against risks, Wen said."We should especially note that the global financial crisis has not ended. We should strengthen our awareness of risks and responsibilities in order to push financial work to new levels," he said.In the future, China will stick to the principal of having the financial industry serve the real economy to prevent virtual bubbles from inflating the economy, he noted.Wen voiced his support for the development of financial innovation, but stressed that this should not escape supervision. "Risk-aversion should be the lifeline of our financial work," he said.He pledged to allow market forces a greater say in deciding fund allocation and to more clearly define the government's role.Financial oversight will be tightened and improved, and banks should establish a more complete and prudent supervision system, he said.According to a statement released after the meeting, China's assets in the financial industry totaled 119 trillion yuan (18.8 trillion U.S. dollars) at the end of November 2011, a 149-percent increase from that at the end of 2006.As of the end of September 2011, the banking capital adequacy ratio stood at 12.3 percent, 5 percentage points higher than that at the end of 2006, while the non-performing loan ratio was 0.9 percent, 6.2 percentage points lower than that at the end of 2006.

RIO DE JANEIRO, Dec 15 (Xinhua) -- Brazilian President Dilma Rousseff Thursday signed a law banning smoking in public spaces and tobacco advertising at sale places in his country.Smoking in all enclosed public spaces, defined as free access areas used simultaneously by several people, is forbidden in the new law.It also prohibits tobacco advertising such as posters or banners at sale places. Previously the ban was only imposed on TV, radio and billboards advertising.In addition, the law increases the taxes and establishes minimum prices over the tobacco products to discourage buyers, therefore the cigarettes prices are expected to increase 20 percent in 2012 and 55 percent by 2015.Health warnings are also required on both sides of cigarette packs to alert consumers about the consequences of their smoking habit.The law is welcomed by some anti-smoking groups."In addition to protecting the health of its citizens, Brazil has also set an example for the world," said Matthew Myer, president of Campaign for Tobacco-Free Kids.
