BEIJING Jan. 10 (Xinhuanet) -- Scientists have found a plant in Brazil using leaves to capture the tiny worms in the soil, according to Monday's Proceedings of the National Academy of Sciences in the U.S.The plant, named Philcoxia, was found in the tropical grassland of Brazil, where the biodiversity is well conserved.As the scientists searching for the answer of why the plant grows the leaves underground, they found the 1.5 millimeters-wide leaves can trap the worms and produce a digestive enzyme to help its roots to absorb the nutrition.Although it is not the first meat-eating plant to be discovered, the finding has still "broaden up our perception about plants," according to researcher Rafael Silva Oliveira, a plant ecologist at the State University of Campinas in Brazil.It suggests that carnivorous plants "may have evolved independently more times in plants than previously thought," he added

WASHINGTON, Nov. 16 (Xinhua) -- Supervised exercise was shown to be more effective than stenting or medication for improved walking ability in patients with peripheral artery disease (PAD), according to a U.S. study reported Wednesday at the 2011 American Heart Association Scientific Sessions meeting.The research group reported that of 111 patients studied in the randomized trial, the most effective treatment proved to be supervised exercise based on the results of a treadmill test taken at baseline and again at six months. Patients who were in the supervised exercise group improved by a mean of 4.6 minutes in the treadmill test, while the group who received stents improved by a mean of 2.5 minutes. However, researchers found that self-reported quality of life measurements proved to be higher in the group that received stents, even though their ability to walk did not improve as greatly as the group that received supervised exercise rehabilitation.The findings were published in the November issue of the journal Circulation. The researchers believe that more studies are necessary, although supervised exercise may be an effective treatment recommended for PAD patients with claudication.PAD is a condition in which plaque builds up in the arteries and affects blood flow, especially to the legs. It is estimated that between 10 and 12 million people suffer from PAD in the United States. One symptom of PAD is known as claudication, a painful cramping of the leg muscles that limits the patient's ability to walk. It affects nearly 2 million people who suffer from PAD, and results in a sedentary lifestyle and poor quality of life.Current U.S. guidelines for the treatment of claudication include pharmacotherapy, supervised exercise rehabilitation and lower extremity revascularization using stents.

BEIJING, Dec. 11 (Xinhua) -- China is faced with severe challenges in collecting enough blood plasma to produce medicines, Health Minister Chen Zhu said Sunday.Chen called on the public to join blood donation after donating blood plasma at the Beijing Red Cross Blood Center on Sunday, the fifth time since he took office in 2007.Blood plasma is needed to make blood products like prothrombin complex which is vital for hemophiliacs.The total volume of blood plasma collected last year was 4,180 tonnes, while the volume needed to produce enough medicines was 8,000 tonnes, said a statement from the ministry. The situation became even worse this year.Donations of blood plasma in China fell dramatically in recent years, as a result of safety concerns from donors and the government's efforts to regulate blood collection after contamination triggered HIV infection scandals.In an overhaul of plasma collection services in 2004, the ministry closed 262 donation centers, leaving only 138 in operation, resulting in the plasma donations falling at least one-third from 5,000 tonnes in 2003.Blood plasma are currently collected at 144 designed stations across the mainland. The stations, as requested by law, are all owned by major manufacturers of blood products.Chen promised to encourage qualified drug makers to set up more collection stations in the next five years.He also assured the public the safety of blood donation at authorized stations.

BEIJING, Jan. 15 (Xinhua) -- The winning of Ma Ying-jeou and Kuomintang (KMT) in Saturday's elections may open new chances for the peaceful development of cross-Strait relations.The results of the elections have indicated that the peaceful development of the cross-Strait relations is a correct path and has been widely recognized by the Taiwan people.Any persons and any political parties of Taiwan should follow this trend, so that they could earn recognition and support.Moreover, the victory of Ma and the KMT may represent a new opportunity for the development of the cross-Strait relations.With joint efforts of the two sides to fortify and enhance the existing mutual trust, there will be a even brighter prospect and further progresses in the cross-Strait talks, exchanges and cooperation.However, the two sides should be wary that the situation in the island is still complicated and the "Taiwan independence" stance will continue to haunt the cross-Strait relations development.There are still some long-term disputes and divergences existing between the two sides that await resolving.This year's elections were carried out under a background in which the cross-Strait relations have been significantly improved. The positive effects of the peaceful development of the cross-Strait relations have fully emerged.Over the past four years, the two sides of the Taiwan Strait have established a political mutual trust based on opposition to the "Taiwan independence" stance and adherence to the "1992 Consensus."The two sides resumed regular talks between the mainland's Association for Relations Across the Taiwan Straits (ARATS) and the Taiwan-based Straits Exchange Foundation (SEF) in 2008.The opening of "three direct links" of cross-Strait mail, trade, air and shipping services, has also pushed forward the cross-Strait economic cooperation into a brand-new stage.These achievements have brought about real benefits to the people on both sides of the Strait, especially the people in Taiwan.The cross-Strait economic cooperation has also helped the island's economy to buoy up from blows of the global financial crisis.The peaceful development of the cross-Strait ties have won a widespread support among the Taiwan people and it is also appreciated by the international community.During the election campaigns, whether to stick to the 1992 Consensus became a major field of cross fires among candidates. Ma had stood out and gained positive momentum with his cross-Strait policies.Numbers of Taiwanese notables, business tycoons as well as the small and medium-sized enterprise owners and the grassroots people have also expressed their stance for the "1992 Consensus" and their aspiration for further peaceful development of the cross-Strait ties.Under the public's pressure, the Democratic Progressive Party and its candidate Tsai Ing-wen have to lower their voices for "Taiwan independence."But their denial of the "1992 Consensus" and the stance of "one country on each side" could not abate the people's doubts and worries and finally led to their failure in the elections.Judged from the election, peaceful development of cross-Strait relations have developed from a concept to reality, benefitting people from different backgrounds and recognized by the public.

BEIJING, Nov. 3 (Xinhua) -- Two Chinese spacecraft accomplished the country's first space docking procedure early Thursday, silently coupling in space more than 343 km above Earth's surface.Nearly two days after it was launched, the unmanned spacecraft Shenzhou-8 docked with space lab module Tiangong-1 at 1:36 a.m., marking another great leap for China's space program.The success of the docking procedure makes China the third country in the world, after the United States and Russia, to master the technique, moving the country one step closer to establishing its own space station.A video grab taken from the China Central Television on Nov.3, 2011 shows the Shenzhou-8 spacecraft docking with the Tiangong-1 space lab module. Unmanned spacecraft Shenzhou-8 docked with space lab module Tiangong-1 early Thursday, according to the Beijing Aerospace Control Center.President Hu Jintao, who is in France for the G-20 summit, sent a congratulatory message on the success of the country's first-ever space docking."Breakthroughs in and acquisition of space docking technologies are vital to the three-phase development strategy of our manned space program," Hu said in the message.Hu said he wishes all the program participants to try all out to fulfill a complete success of the whole mission after the smooth docking.Other leaders, including Wu Bangguo, Wen Jiabao, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang, who are Standing Committee members of the Political Bureau of the Communist Party of China Central Committee, watched the mission at the Beijing Aerospace Flight Control Center.China is now equipped with the basic technology and capacity required for the construction of a space station, said Zhou Jianping, chief designer of China's manned space program."This will make it possible for China to carry out space exploration on a larger scale," he said."The capability increases China's ability to act independently in space, as well as its ability to cooperate with others," said Gregory Kulacki, senior analyst and China project manager at the global security program of the Union of Concerned Scientists, a nonprofit scientific advocacy group based in the United States."China's pursuit of an original solution to space docking, that is based on their understanding of the experience of other nations, could lead to innovations or experiences other space-faring nations could find useful," Kulacki said.The world's first space docking was achieved in 1966, when the manned U.S. spacecraft Gemini 8 docked with an unmanned Agena Target Vehicle.Forty-five years later, the maneuver remains a technological challenge. Many of mankind's 300-plus attempts have been met with difficulties or resulted in failure."To link up two vehicles traveling at 7.8 km per second in orbit, with a margin of error of no more than 20 centimeters, is like 'finding a needle in a haystack'," Zhou said.The Shenzhou-8 and Tiangong-1 will separate after flying together for 12 days. After that a second docking procedure will be conducted.Rendezvous and docking, essential to exploring space beyond Earth's orbit, create the possibility of building space stations, resupplying them, transferring astronauts and rescuing them.Without this key know-how, exploration of the moon and beyond requires carrier rockets with significant amounts of thrust. China does not currently possess rockets of this magnitude.Shenzhou-8 and Tiangong-1 both weigh about 8 metric tons, well within the delivery capacity of the Long March 2F rocket. A permanent orbiting space station is designed to be as heavy as 60 metric tons, with docking ports accommodating both manned and freight space vehicles.The interior of both the Shenzhou-8 and Tiangong-1 is an actual environment in which astronauts can live and work. After the Shenzhou-8 tests, the Tiangong-1 will remain a target orbiter for more docking procedures in 2012 by the Shenzhou-9 and -10 spacecraft, at least one of which will be manned to conduct manual docking.Although the Shenzhou-8 is unmanned, it is equipped with devices to record images and data that will help China make improvements to its spacecraft design and astronaut training.Two female astronauts are now believed to be on the active duty roster for future Shenzhou missions, said Chen Shanguang, director of the Astronaut Center of China (ACC)."We must assess both male and female astronauts to verify if human beings can live in space, as there are huge differences between men and women in spite of their common generalities," Chen said."Space exploration activities would be incomplete without the participation of female astronauts," Chen said.The Chinese spacecraft also feature collaborative space experiments under the framework of a Chinese-German science and technology cooperation.German scientists designed bio-incubators for the experiments, while their Chinese counterparts were in charge of the development of control equipment, China's manned space program spokeswoman Wu Ping said.
