NEW YORK, Oct. 3 (Xinhua) -- For the 34-year-old Alexis Steinman, Oct. 3 would have been a great day, because her father Ralph Steinman was announced winner of the 2011 Nobel Prize in Physiology or Medicine.But as she talked to Xinhua at the Rockefeller University where his father worked, she said the day was rather "bittersweet"."This is the moment, but my Dad was not here," said Alexis, trying to hold her tears.The Canadian-born cell biologist Ralph Steinman died of pancreatic cancer on Friday at the age of 68, three days before he was announced the joint winner along with Prof. Bruce Beutler and Prof. Jules Hoffman for the Nobel Prize in Physiology or Medicine."We even talked about the Nobel Prize days before his death," Alexis added."We were like 'OK Dad, I know things aren't going well but the Nobel, they are going to announce it next Monday'. And he was like 'I know I have got to hold out for that. They don't give it to you if you have passed away,'" she said."It's really impossible to describe how our family is feeling right now. We're devastated to have lost Ralph,"Steinman' s son Adam Steinman told reporters at the press conference at Rockefeller University. "We're so incredibly proud of Dad for receiving this wonderful honor ... We know he will live on through his scientific contributions," he said.Rockefeller University president Marc Tessier-Lavigne told reporters during Monday's press conference that the university only heard of Steinman's death from the family about half an hour after news of the Nobel prize came out from Sweden."We are all deeply saddened by his death, " said Tessier- Lavigne , adding that Steinman had been treating himself with a groundbreaking therapy based on his research into the body's immune system.He said Steinman's research has laid the foundation for numerous discoveries in the critically important field of immunology, and it has led to innovative new approaches in how people treat cancer, infectious diseases and disorders of the immune system.Steinman's first student and close colleague Michel Nussenzweig told the press conference packed with reporters, students and professors that "one of the interesting things about Ralph and his discovery is that no one believes it for a really long time.""What was amazing about Ralph was that he just knew that, even though nobody else believed it, this was really important, and he persisted, and finally after a very long time, everyone just found out it was true," Nussenzweig said."Ralph worked until last week. His dream was to use his discovery to make vaccines and it is a dream that is pretty close, and we are all continuing to work to make that come true," he added.The Nobel Foundation made a statement after learning Steinman's death, saying that the decision to award the prize to the Canadian scientist would remain unchanged despite his death, and the prize money will be transferred to his estate.

BEIJING, Jan. 3 (Xinhua) -- A collection of China's nine white papers issued in 2011 has been published in both Chinese and English, according to a statement issued by the publisher on Tuesday.By giving a clear and precise illustration of China's policies, principles and progress in subjects like national defense, law, climate change and international trade, the white papers can help the world know about, and understand, China, the statement said.The white papers are titled, "China's National Defense in 2010," "China's Foreign Aid," "Sixty Years Since the Peaceful Liberation of Tibet," "China's Peaceful Development," "The Socialist System of Laws with Chinese Characteristics," "New Progress in Development-oriented Poverty Reduction Program for Rural China," "China's Policies and Actions for Addressing Climate Change (2011)," "China's Foreign Trade" and "China's Space Activities in 2011."The white papers were all published by the Information Office of the State Council on behalf of the Chinese government.The latest one on space activities was issued last Thursday.

WASHINGTON, Jan. 2 (Xinhua) -- A systematic review of previous studies suggests that there may be a positive connection between physical activity and children's academic performance, according to a report published Monday in the Archives of Pediatrics & Adolescent Medicine.A group of scientists at the Vrije Universiteit (Free University) Medical Center in the Netherlands reviewed evidence on the relationship between physical activity and academic performance because of concerns that pressure to improve test scores may often mean more instructional time for classroom subjects with less time for physical activity.The authors identified 10 observational and four interventional studies for review, 12 of which were done in the United States, one in Canada and one in South Africa. Sample sizes ranged from 53 to about 12,000 participants between the ages of eight years and 18 years old. Follow-up varied from eight weeks to more than five years."According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance. The findings of one high-quality intervention study and one high-quality observational study suggest that being more physically active is positively related to improved academic performance in children," the report said.Background information in the article suggests that exercise may help cognition by increasing blood and oxygen flow to the brain, increasing levels of norepinephrine and endorphin to decrease stress and improve mood, and increasing growth factors that help create new nerve cells and support synaptic plasticity."More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using reliable and valid measurement instruments to assess this relationship accurately," the report concluded.

SANYA, Hainan, Dec. 4 (Xinhua) -- The five BRICS nations intend to focus and work together on developing alternative energy sources.When Bu Xiaolin, vice governor of China's coal-rich Inner Mongolia autonomous region, spoke over the weekend in front of hundreds of BRICS delegates on regional energy strategies, she mentioned little of the fossil fuels that have long contributed to the region's growth.Like many other speakers at the 1st BRICS Friendship Cities and Local Governments Cooperation Forum, which ran from Dec. 1-3 in Sanya, Hainan province, she devoted large part of her speech to discussing wind and solar energy."Facing the prospects of running out of fossil energy and the related environmental issues, developing new energy is an inevitable choice," said Bu.The forum at this seaside resort over the weekend attracted hundreds of local governors, scholars and business people from the BRICS nations -- Brazil, Russia, India, China and South Africa -- to discuss city-to-city cooperation, and new energy was among the top agenda topics.Consensus had been reached at the forum that the five countries should strengthen dialogue and cooperation for provincial and local partnerships, including infrastructure, green economy and technology transfer."We are very willing to cooperate with BRICS countries on new energy innovations, promotion and market development," said Bu.According to Bu, Inner Mongolia has huge potential in new energy, with 380 million kilowatts of exploitable wind power resources, accounting for more than half of China's on-shore wind power resources.The region is aiming for a total installed capacity of 33 million kilowatts for wind power and one million kilowatts for solar power by the end of 2015, she added.At national level, the Chinese central government expects to bring the country's total wind power installed capacity up to 150 million kilowatts in the next five years, according to national development plans.Meanwhile, in Brazil, there is movement to replace fossil energy with new energy in daily use, said Jailson Lima Da Silva, State Representative of the National Union of State Legislatures of Brazil.The country is working to increase the nation's wind power capacity, and new energy is expected to account for 65 percent of the nation's total energy consumption, he said."Brazil is optimistic on wind power exploitation, which will be one of the major fields of future investment," he said.Silva expressed hopes to work with China on new energy, especially solar power and biomass energy. "Brazil has large potential in solar energy, while China is a leading producers of solar equipment," he said.According to Mlibo Qoboshiyane, a member of the Executive Council of Eastern Cape, South Africa, the African nation is also investing extensively in wind and solar energy.South Africa has just unveiled a 12-billion-U.S.-dollar program on renewable energy development, which would largely be spent on wind and solar power and reduce the use of traditional energies, said the official.It would be helpful to exchange technologies and valuable information between the BRICS countries to keep consumption of new energies sustainable and affordable, he said. 

SAN FRANCISCO, Oct. 10 (Xinhua) -- Apple announced on Monday that pre-orders of its iPhone 4S have topped 1 million in a single day, surpassing the previous single-day pre-order record of the company's smartphone.The iPhone 4S pre-orders surpassed 1 million in the first 24 hours and the previous single day pre-order record held by iPhone 4 is 600,000, according to Apple."We are blown away with the incredible customer response to iPhone 4S," Philip Schiller, Apple's senior vice president of worldwide product marketing, said in a statement."The first day pre-orders for iPhone 4S have been the most for any new product that Apple has ever launched and we are thrilled that customers love iPhone 4S as much as we do," he added.U.S., newly installed Chief Executive Officer Tim Cook takes stage to give a general introduction of Apple's products, Oct. 4, 2011. Apple Inc. last Tuesday unveils iPhone 4S, the much-anticipated latest generation of iPhone.The iPhone 4S, which looks the same as the iPhone 4 but has major hardware upgrade inside, is available for pre-order last Friday and set to first arrive in stores in the United States this Friday.So far, iPhone 4, which, according to Apple, has been sold more than the first three generations of iPhones combined, is Apple's best selling iPhone.The pre-order numbers are good news for Apple as the initial introduction of iPhone 4S last Tuesday has not lived up to the anticipation of some investors and analysts, and spurred a new wave of concerns about whether the company could keep its innovation momentum in the wake of the passing of its co-founder Steve Jobs last Wednesday.
