WASHINGTON, April 5 (Xinhua) -- NASA and co-researchers from the United States, the Republic of Korea and Japan have found a new mineral named "Wassonite" in one of the most historically significant meteorites recovered in Antarctica in December 1969, the U.S. space agency said on Tuesday in a statement.The new mineral was discovered within the meteorite officially designated Yamato 691 enstatite chondrite. The meteorite likely may have originated from an asteroid orbiting between Mars and Jupiter. Wassonite is among the tiniest, yet most important, minerals identified in the 4.5-billion-year-old sample.The research team, headed by NASA space scientist Keiko Nakamura-Messenger, added the mineral to the list of 4,500 officially approved by the International Mineralogical Association."Wassonite is a mineral formed from only two elements, sulfur and titanium, yet it possesses a unique crystal structure that has not been previously observed in nature," said Nakamura-Messenger.In 1969, members of the Japanese Antarctic Research Expedition discovered nine meteorites on the blue ice field of the Yamato Mountains in Antarctica. This was the first significant recovery of Antarctic meteorites and represented samples of several different types.As a result, the United States and Japan conducted systematic follow-up searches for meteorites in Antarctica that recovered more than 40,000 specimens, including extremely rare Martian and lunar meteorites.Researchers found Wassonite surrounded by additional unknown minerals that are being investigated. The mineral is less than one-hundredth the width of a human hair or 50x450 nanometers. It would have been impossible to discover without NASA's transmission electron microscope, which is capable of isolating the Wassonite grains and determining their chemical composition and atomic structure."More secrets of the universe can be revealed from these specimens using 21st century nano-technology," said Nakamura- Messenger.The new mineral's name was approved by the International Mineralogical Association. It honors John T. Wasson, professor at the University of California, Los Angeles. Wasson is known for his achievements across a broad swath of meteorite and impact research, including the use of neutron activation data to classify meteorites and to formulate models for the chemical makeup of bulk chondrites.

BEIJING, Feb. 8 (Xinhua) -- As the Chinese Lunar New Year hoilday ended Tuesday, waves of Chinese residents began their journey back to work, as they boarded trains, airplanes and buses.The China Meteorological Administration announced Tuesday that a cold front would cause temperatures to fall by 4 to 12 degrees Celsius in most parts of the country, while some areas in the northwest, north and southwest will see rainfall or snow from Wednesday to Friday.Fleets of motorbikes carrying thousands of migrant workers passed through national roads again on Tuesday.The Ministry of Public Security said it set up 8,300 service stations along the country's major highways to provide free food, medicine, and rest stops for motor-riding migrant workers. The stations also sent police cars to clear the way for large groups of motorists.Chen Tianchong, a migrant worker from Muge County, Guigang City of southwest China' s Guangxi Zhuang Autonomous Region and 38 of his fellow migrant worker started their journey on motorcycles at 4:30 a.m. on the foggy National Road 324, which is a 2,712-kilometer road linking five provinces of Fujian, Guangdong, Guangxi, Guizhou and Yunan in southern China.A motorcycle usually carried two people, often a couple, sometimes with a child sandwiched in between. They would wrap themselves in thick outerwear to battle the cold weather at night. Limited access to cheap public transportation had forced many migrant workers to make their trips home on their own."I promised my boss that I would go back to the factory in Guangdong before Wednesday," said Chen.Chen said that they might arrive at Dali County, Shunde City of south China's Guangdong Province around eleven at night, after more than 18 hours riding a motorcycle from their hometown. By this way, each family may save more than 1,000 yuan - half of their monthly income.Zhong Fei, another migrant worker also from Guangxi, chose this way home during the Spring Festival for the past three years. Zhong told Xinhua that earning money for his family was the most important thing and the exhausting trip was nothing.From Guangdong alone, one of China's manufacturing bases, over 100,000 migrant workers left for home on motorbikes, said the local police. The Spring Festival travel rush started in China in the late 1980s, when millions of farmers from inland China moved to coastal cities to work.In spite the increasing popularity of motor cycles, the majority of Chinese travelers still prefer trains or buses. Shandong province embraced the post-holiday passenger rush Tuesday, with railway stations witnessing 200,000 passengers in a single day.Highway toll booths near Beijing, Shanghai, Tianjin and other big cities in China have become clogged.Passengers are also snapping up airplane tickets. China Southern Airlines had increased flights from 30 to 70 flights per day.Official forecasts indicate that this year's Spring Festival holiday may see a record 2.85 billion passenger trips nationwide, as Chinese workers return home from across the country for family reunions and go back to work after the holidays.

BEIJING, Feb. 13 (Xinhua) -- Chinese Premier Wen Jiabao has invited a group of ordinary people from all walks of life to seek their opinions on drafts of a government work report and the country's economic and social development blueprint for the next five years.The representatives, including a farmer, a migrant worker, a rural doctor and a community worker, were invited to Zhongnanhai, the central leadership compound in downtown Beijing, on Jan. 25. Some details of the meeting were made public on Sunday.At the meeting, Wen said, "Ordinary people are in the best place to evaluate government's work, and listening to public opinion will allow us to know how government policies are carried out at grass-roots level, and what difficulties people are facing."Liu Hongwei, a farmer from northeastern Heilongjiang Province, suggested that government increases investment in agricultural water conservancy projects in case of natural disasters such as severe drought this winter in north China.Wen said this year the government would invest more in water conservancy while starting retrofitting the grid in rural areas to guarantee electricity supply for both residential consumption and irrigation of crops.Wen also assured Liu that the government would raise purchasing price of grains so as to protect the interests of grain farmers.Xie Yuanli, an electric welder from northeastern Jilin Province, expressed his wish that governments give greater support and care to industrial workers.Dong Zhiping, a migrant worker working on construction site in central Hunan Province, complained that some enterprise owners refuse to pay migrant workers insurance against work-related injuries, and many migrant workers are not aware of their rights."Once a worker gets injured, his family would suffer grave financial difficulties without the insurance cover," Dong said.Wen said the government was working on the issue, such as promoting better implementation of government regulations on workplace injury-related insurance, which became effective in 2003.The meeting also touched upon issues of favorable policies to small and medium-sized enterprises, fair treatment of village doctors, stronger support to facilities for senior citizens, boosting space science and technology and improving vocational training, among others.The drafts of the 12th five-year program, or the national development plan for 2011 to 2015, and the government work report will be delivered for review early next month at a plenary session of the National People's Congress (NPC), China's national legislature.

SYDNEY, May 27 (Xinhua) -- A toddler and a policeman have become the latest victims of a rare and potentially deadly mosquito-borne disease in Western Australia (WA), local media reported on Friday.The two-year-old child contracted Murray Valley encephalitis (MVE) in the Kimberley of WA and is now in Royal Darwin Hospital in a stable condition, according to Australian Associated Press (AAP).The 29-year-old police officer, who was recently contracted the disease at an Aboriginal community of WA, has emerged from a coma in a Perth hospital but is still unable to communicate.It is not known if the victims from WA's far north will fully recover.In April 2011, a man who had been traveling in WA's northwest became the first person in the state to die from the disease in three years.A 19-year-old Canadian tourist also died after contracting MVE while traveling through the Northern Territory earlier in May.A WA Health Department spokeswoman said nine West Australians had contracted MVE so far in 2011. Several people remain very ill in hospital, she said.

BEIJING, Jan. 20 (Xinhua) -- Major foreign media have been positive in their coverage so far of Chinese President Hu Jintao's four-day visit to the United States, which began Tuesday.AP said Obama was lavishing the grandest of White House welcomes on Hu as the leaders of the two powers looked for common ground on economic and security issues without alienating their domestic audiences."I absolutely believe China's peaceful rise is good for the world, and it's good for America," Obama said.The Washington Post said Obama stated several times that the United States does not fear a stronger China and that Washington has no interest in blocking Beijing's emergence as a superpower.Chinese President Hu Jintao speaks at a welcoming ceremony held by U.S. President Barack Obama on the South Lawn of the White House in Washington, the United States, Jan. 19, 2011It also said Hu's visit, in addition to serious policy matters, featured a fair amount of glitz. He arrived at the White House to a 21-gun salute and was sent off with a state dinner.The Wall Street Journal said President Obama is looking to assure Americans that they should not fear China's economic rise, using Chinese President Hu's high-profile state visit to announce job-creating business deals worth billions of dollars to U.S. companies.The two sides played down differences and stressed areas of cooperation, ranging from a plan to cooperate on nuclear security to an extension of the loan of two Chinese pandas to Washington's zoo.CNN said at a joint news conference held by the two leaders, Obama praised a "spirit of cooperation that is also friendly competition." President Hu told reporters the countries' relationship is based on "mutual respect and mutual benefit."Obama stressed common interests between the nations while toasting the Chinese leader at the White House, CNN said.VOA said dozens of business deals this week will increase U.S. exports by more than 45 billion U.S. dollars and increase China's investments in the United States by several billion dollars.AFP said that, during Hu's visit, the United States and China had announced a raft of trade deals worth 45 billion dollars. The deals, spanning sectors as diverse as agriculture, gasification, railways and hybrid buses, would support 235,000 U.S. jobs."The scope of Wednesday's deals were seen as evidence of the rapidly deepening business links between the two countries," AFP said.The Los Angeles Times said in its report that two leaders "unapologetically acknowledged major differences on economic issues and human rights" in a White House summit Wednesday, but also pledged cooperation to stabilize relations between the world's two largest economies.Obama said the United States hoped to benefit from China's "rapid and peaceful" growth, the report said.The Times of India said, "China's President Hu Jintao arrived in Washington on Tuesday on a four-day U.S. visit that is being watched in every capital on the planet."O Estado de S. Paulo, a local daily newspaper in Brazil, quoted President Hu's words, saying that China and the United States "stand to gain from a sound China-U.S. relationship, and lose from confrontation," thus they needed to discard the "Cold War mentality."The newspaper also said the two nations both hoped to take the visit as an opportunity to rebuild mutual trust despite some frictions over the past year.
