MOSCOW, May 13 (Xinhua) -- The main and backup crews that will fly to the International Space Station in June have passed preflight tests and are ready for space travel, the Russian Cosmonauts Training Center said Friday.The main crew includes Russian cosmonaut Sergei Volkov, Japanese astronaut Satoshi Furukawa and American astronaut Michael Fossuma.A Russian spaceship Soyuz TMA-02M will send the crew to the space station on June 8, Interfax news agency reported.The backup crew includes members from Russia, the Netherlands and the United States.The crews were tested on the various emergency situations they could face during the flight.Next Monday, the commission will make a final choice of crewmembers for the launch.The crew will spend 161 days in orbit and conduct three space walks.

BEIJING, May 24 (Xinhuanet) -- Scientists revealed for the first time the molecular structure of proteins, which enables bacteria to transfer electrical charges, according to a new study. The revelation was published in Proceedings of the National Academy of Sciences in the U.S. on Monday.Scientists used a technique called "x-ray crystallography" to reveal the molecular structure of proteins, which work as atom-sized "wires" discharging excess electricity."This is an exciting advance in our understanding of how some bacterial species move electrons from the inside to the outside of a cell," said lead author Tom Clarke of the University of East Anglia's School of Biological Sciences in Norwich, England.He said this discovery means "We can now start developing efficient 'bio-batteries' as the viable energy source in the future."Still, it could take perhaps a decade to go. Before that, existing uses of such bacteria needed to become 100 or 1,000 times more efficient, he said.The advance could also hasten the development of microbe technology that can help clean up oil or uranium pollution, he said.Microbes might in future be enlisted to clean up nuclear accidents such as Japan's Fukushima Daiichi disaster, he added.

BEIJING, Jan. 26 (Xinhua) -- China's civil affairs ministers visited survivors of last year's 7.1-magnitude Yushu earthquake and Zhouqu mudslide prior to China's lunar new year.Dou Yupei, vice minister of Civil Affairs, led a team to Yushu in northwest China's Qinghai Province to visit quake survivors and local cadres beginning on Sunday.Dou told Xinhua that quake survivors in Yushu now had access to food, clothing, safe drinking water, shelters and medical services, and the reconstruction of quake-damaged houses was well underway.Further, the ministry has distributed 45,000 cotton-padded tents to Yushu to house survivors during the extremely cold winter on the Qinghai-Tibet plateau.So far, 160,000 tents have been set up to assure that all survivors have a roof overhead, according to the ministry's statement issued Wednesday.Yushu was jolted by a 7.1-magnitude earthquake on April 14, leaving 2,200 people dead and 220,000 local residents affected.Another vice minister, Sun Shaocheng, visited survivors from a massive mudslide that left 1,700 people dead or missing in Zhouqu, Gansu province.To provide warm shelters to survivors, the Zhouqu county government invested three million yuan (455,000 U.S. Dollars) in renovating vacant school buildings or installing facilities in newly-built apartments.All survivors who previously had taken shelter in make-shift tents were relocated to these buildings before Oct. 13, according to the ministry's statement.

LOS ANGELES, April 14 (Xinhua) -- Vegetarians experience a much lower risk of metabolic syndrome than non-vegetarians, U.S. researchers have found.Researchers at Loma Linda University in California based their findings on analysis of more than 700 adults randomly sampled from a long-term study of the lifestyle and health of almost 100,000 Seventh-day Adventist Christians across the United States and Canada.While 25 percent of vegetarians had metabolic syndrome, the number significantly rises to 37 percent for semi-vegetarians and 39 percent for non-vegetarians, according to the study published in the April issue of the journal Diabetes Care.The findings showed that the risk of developing metabolic syndrome is 36 percent lower among vegetarians than non- vegetarians.This means that vegetarians are less likely to develop heart disease, diabetes and stroke -- three major conditions that are closely linked with metabolic syndrome, the researchers say.The study also found that vegetarians, though slightly older than non-vegetarians, had lower triglycerides, glucose levels, blood pressure, waist circumference, and body mass index (BMI). Semi-vegetarians, meanwhile, also had a significantly lower BMI and waist circumference compared to those who ate meat more regularly.The findings will not be affected by other factors such as age, gender, race, physical activity, calories consumed, smoking, and alcohol intake, the researchers say."In view of the high rate of metabolic syndrome in the United States and its deleterious health effects, we wanted to examine lifestyle patterns that could be effective in the prevention and possible treatment of this disorder," says lead researcher Nico S. Rizzo, PhD."I was not sure if there would be a significant difference between vegetarians and non-vegetarians, and I was surprised by just how much the numbers contrast," he says. "It indicates that lifestyle factors such as diet can be important in the prevention of metabolic syndrome."

SHANGHAI, May, 13 (Xinhua) -- Scientists attending a recent high-level conference on robotics agreed that great progress has been made in the field, but strict rules for the safe usage of robots should be implemented."Four years ago, if you went into a Chinese factory and said 'robots can help you work,' you would be kicked out. But now, China has a large industrial robot market, along with Japan, the Republic of Korea and the United States," says Li Zexiang, general chair of the 2011 International Conference on Robotics and Automation (ICRA 2011), which concluded Friday in Shanghai.Chinese robotics researchers have suggested to the government that rules and regulations for robot usage should be created. Professor Wang Tianmiao from the Beihang University (BUAA) told Xinhua about the suggestions during the conference.Wang says that in the future, it might not be possible for artificial intelligence to take the place of humans in some social roles. However, Wang says that mankind should pay close attention to the possible dangers of advancements in robotics, as the industry is currently undergoing dramatic changes.The five-day conference, which is organized by the Institute of Electrical and Electronics Engineers (IEEE), took place in China for the first time ever since its first session in 1984, which took place in the city of Atlanta in the United States.Media reports show that Japan, the Republic of Korea (ROK) and several Western countries have already drafted rules about the safe use of robots.
