New York, Sept. 23 (Xinhua) -- A Chinese scientist was presented a prestigious U.S. award on Friday for the discovery of artemisinin, a drug therapy for malaria that has saved millions of lives across the globe, especially in the developing world. Pharmacologist Tu Youyou, 81, became the first scientist on the Chinese mainland to win Lasker Award, known as "America's Nobels" for their knack of gaining future recognition by the Nobel committee.Tu, a scientist at the China Academy of Chinese Medical Sciences in Beijing, pioneered a new approach to malaria treatment that has benefited hundreds of millions of people and promises to benefit many times more. By applying modern techniques and rigor to a heritage provided by 5000 years of Chinese traditional practitioners, she has delivered its riches into the 21st century."Not often in the history of clinical medicine can we celebrate a discovery that has eased the pain and distress of hundreds of millions of people and saved the lives of countless numbers of people, particularly children, in over 100 countries," Lucy Shapiro, a member of the award jury and professor of Stanford University, said while describing Tu' s discovery.Shapiro said the discovery, chemical identification, and validation of artemisinin, a highly effective anti-malarial drug, is largely due to the "scientific insight, vision and dogged determination" of Professor Tu and her team. She thought Professor Tu's work has provided the world with arguably the most important pharmaceutical intervention in the last half century."The discovery of artemisinin is a gift to mankind from traditional Chinese medicine," Tu said while receiving the award. "Continuous exploration and development of traditional medicine will, without doubt, bring more medicines to the world."

BEIJING, Aug. 3 (Xinhuanet) -- NASA Tuesday confirmed a 4-foot in diameter sphere debris as a fuel tank that was part of the space shuttle Columbia's electrical power system,according to U.S. news reports.NASA engineers identified the 4-foot piece of spherical debris as one of the18 tanks that held chilled oxygen and hydrogen used by the shuttle's electricity-generating fuel cells.This Aug. 1, 2011 handout photo provided by the Nacogdoches Police Department shows a 4-feet in diameter sphere found in Lake Nacogdoches, Texas on Monday, Aug. 1. Police say low water levels at the lake during the drought have led to recovery of a container-like object that could be from space shuttle Columbia. The shuttle broke apart and burned in February 2003, scattering remnants over East TexasPolice in the city of Nacogdoches, about 160 miles northeast of Houston, said Monday the low water levels of Lake Nacogdoches during the record drought revealed an unexpected object that could be from space shuttle Columbia. The shuttle broke apart and burned as it re-entered the atmosphere on February 1, 2003.The tank will be moved to the Kennedy Space Center, where the rest of the Columbia is stored. Approximately 40 percent of the spacecraft has been recovered.

THE HAGUE, June 24 (Xinhua) -- Bird flu was discovered at a poultry farm in the central Dutch province of Flevoland, the Ministry of Agriculture said Friday.It said the virus discovered was a mild variant. The farm's 47,000 chickens were slaughtered to prevent the virus turning into a contagious and deadly variant.It remains uncertain whether the chickens were infected with the high or low pathologene H7 variant. The low pathologene version can mutate into a high pathologen, which is extremely transmittable.Poultry from other farms in a zone of three kilometres of the contaminated farm will be tested. A prohibition of transport for poultry, eggs and poultry manure has been set.

CANBERRA, Aug. 3 (Xinhua) -- As many as a quarter of Australian women have experienced some form of assault or sexual abuse, and the higher proportion of the abuse, the higher rates of metal illness a woman tends to suffer from, a new study released on Wednesday found.Researchers from the University of Melbourne and the University of New South Wales conducted the study survey of 4451 Australian women aged 16 to 85. It looked at their experience of the four most common types of gender-based violence - sexual assault, rape, stalking and being badly beaten by their partners.About 15 percent of Australian women report sexual assault, while eight percent report rape, 10 percent said they have a stalker and eight percent report being beaten by their partner.It found strong links between those four types of violence and mental health problems including attempted suicide, posttraumatic stress disorder, panic attacks, depression, anxiety, and substance abuse.Among the women who experienced at least one form of violence, 30 percent had a mood disorder, nearly 40 percent an anxiety disorder, 23 percent were abusing substances and 15 percent were affected by posttraumatic stress syndrome.For the women who suffered higher levels of violence, the rates of anxiety disorders was 77 percent, 52 percent for mood disorders, substance abuse 47 percent and posttraumatic stress syndrome 56 percent.More than six percent of women experienced one form of violent had attempted suicide, compared to 35 percent of women who suffered at least three forms of violence.Public health expert Dr Susan Rees from the University of New South Wales' school of psychiatry, who led the research, said she is especially concerned about the suicide rate of women who are abused."What we found was that there's a high association or a strong association between exposure to gender-based violence and all the three broad classes of mental disorder - so that includes mood, anxiety, substance abuse - and a very high association with attempted suicide," she said in the report released on Wednesday."Women who've not experienced gender-based violence have about a 1.6 percent rate of attempted suicide and that increased to six percent of women who had experienced one type of gender-based violence."She said that gender-based violence was also associated with physical disability, impaired quality of life and a worsening of any existing mental disorders.Dr Rees called for the health care system, particularly psychiatric services, to work closer with women's services to improve support for victims of violence.She added that the federal government also need to underscore the importance of getting to the root cause of the violence against women by looking at attitudes towards women and gender inequality.The study was published in the Journal of the American Medical Association.

BEIJING, July 20 (Xinhuanet) -- Some U.S. soldiers returning from the Middle East have acquired constrictive bronchiolitis, a kind of lung damage virtually unknown in young adults, according to U.S. News & World Report."Respiratory disorders are emerging as a major consequence of service in southwest Asia," said study author Dr. Matthew S. King, an assistant professor of pulmonary and critical care at Meharry Medical College in Nashville, Tenn."In addition to our study, there have been studies showing increases in asthma, obstructive lung disease, allergic rhinitis and a general increase in reports of respiratory symptoms," he added. "Most of the patients say they can’t seem to catch their breath when exerting themselves."On the other hand, Anthony Szema, a physician and engineer at Stony Brook University in New York, has examined a soldier and found tiny complexes of titanium and iron in the man’s lungs, where metals can cause severe damage.Mined separately, the two metals could have gotten together only through a manufacturing process, Szema reported. While the metals’ origin is unclear, he presents a new case study, suspecting garbage-burning pits or exploding devices sent them airborne.While the cases in the study represent only a few dozen people of the hundreds of thousands serving in the Middle East, there is no estimate of how many more might have bronchiolitis.it is recommended that soldiers exercise caution in the field until more is known. Soldiers are now told to wear a mask when burning garbage.
