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. 21 (Xinhua) -- A locomotive producer in central China's Hunan province on Friday rolled out a low-cost magnetically levitated (maglev) train that is more environmental-friendly than conventional ones.The three-carriage train is designed to run at a maximum speed of 100 km per hour and carry 600 passengers, said Xu Zongxiang, general manager of Zhuzhou Electric Locomotive Co. Ltd. of China South Locomotive and Rolling Stock Corporation (CSR). Xu said the new train was much quieter than conventional ones. While a conventional train moves forward by using friction between its wheels and the railway tracks, the maglev train replaces wheels by electromagnets and levitates on the guideway. According to Xu, his company's has minimized the risk of the new maglev train derailing or overturning. "It's ideal for mass transportation, as it is quiet and environmental-friendly. Its manufacturing cost is about 75 percent of a conventional light-rail train," said Xu. The maglev train has a minimum turning radius of 50 meters and can easily run in residential communities or on hilly slopes. "It's an ideal public transport option for Chinese cities and major tourist destinations," said Xu. Railway transport specialist Liu Youmei, also an academician with Chinese Academy of Engineering, said the new train is green, economical and safe. "It can be used for public transport in populous areas and at scenic spots with fragile environments." Liu said China is one of a few countries that have applied maglev technology. Beijing is building a maglev route, the Daitai line (S1), which starts at its IT center in Haidian district, passes through Shijingshan district, and ends in Mentougou district on its western outskirts. The line will be operational next year.The eastern metropolitan of Shanghai runs the world's first commercial maglev system on a 30-km stretch between the downtown business district and Pudong airport. The German-made maglev went into operation on Dec. 31, 2002.

BEIJING, Oct. 2 (Xinhua) -- Chinese archeologists have found evidence indicating that the mysterious ancient city of Loulan (Kroraina) once had highly-developed agricultural systems.Scientists from the Institute of Geology and Geophysics under the Chinese Academy of Sciences conducted remote sensing procedures, field investigations and sample testing in the area and found that there were once large tracts of farmlands in Loulan.The farmland featured regular and straight circumferences stretching for 200 to 1,000 meters as well as irrigation ditches running throughout, said Qin Xiaoguang, a member of the research team.Moreover, researchers found grain particles in the area's ground surface, which are very likely to be remains of crop plants, Qin said.These findings show that irrigation farming had been practiced in Loulan for at least 100 years, Qin said.Qin said they also found canal remains measuring 10 to 20 meters wide and 1.6 meters deep in the Loulan relics, indicating that the city, which is suspected of perishing in drought, was once rich in water resources.The ancient city was a pivotal stop along the famous Silk Road, but mysteriously disappeared around the third century AD.Previous historical records suggested that Loulan's economy was sustained by widespread agricultural activity, but no remains or other evidence had been found before the most recent discoveries.

CAPE TOWN, Nov. 13 (Xinhua) -- The research vessel SA Agulhas has set off from Cape Town on a 10-day polar tour intended to promote dialogue on climate change, authorities confirmed on Sunday.The trip was designed to mark the 17th Climate Conference of the Parties (COP17) to be held in Durban later this month, according to the Department of Environmental Affairs.The voyage, which set off Saturday noon with scientists, academics, students and journalists aboard, would host exhibitions, symposiums and lectures from climate change scientists on the work of the polar research vessel, spokesman Zolile Nqayi said in a statement.The exhibitions and lectures would also highlight the various scientific activities undertaken by the department and its partners in Antarctica and the Southern Oceans, according to the South African Press Association (SAPA).Apart from her research and supply work, the Agulhus also helped to rescue the Magdalena Oldendorff, which became stuck in thick ice in June 2002.In December the SA Agulhas would make its final voyage to Antarctica before retirement.The Agulhas, which has been in service for 33 years, would be replaced by a new vessel under construction in Finland."She served us very well," said Dr Monde Mayekiso, deputy director general of oceans and coasts."The new vessel will have enhanced technologies and capabilities to further understand the ocean environment and to bring that understanding to an increasing number of South Africans, " he said.
