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."

BERLIN, June 6 (Xinhua) -- The German authorities said on Monday that Germany's first sample tests of the allegedly contaminated bean sprouts have found no E. coli strains that have sickened more than 2,000 people in Europe.According to a statement issued by the Agriculture Ministry of the Lower-Saxony state, 23 of 40 samples concerning the suspected sprouts from a market garden in the state have tested negative, and further tests are still pending."Based on the initial findings in tests of some of the samples, especially the seeds, we assume that intensive analytical efforts are needed to prove that the suspected pathogen is really there," the statement said.Beansprouts and salad sprouts are seen in this picture illustration taken in Berlin June 6, 2011.  The German authorities said on Monday that Germany's first sample tests of the allegedly contaminated bean sprouts have found no E. coli strains that have sickened more than 2,000 people in EuropeLower-Saxony's Agriculture Minister Gert Lindemann said Sunday that a market garden in the rural district of Uelzen had provided a connection "involving all the main outbreaks" of the disease.Restaurants and food outlets of almost all E. coli-affected areas had received shipments of sprouts directly or indirectly from the company, state officials said.The German authorities have been racing to track down the source of the pathogen since the outbreak, which has infected people in 12 countries, all of whom had once traveled in northern Germany.More than 600 of those infected have developed Hemolytic Uremic Syndrome, a potentially deadly complication attacking the kidneys.The E. coli source was first thought to be cucumbers from Spain, which has caused huge loses for Spain farmers. However, this conclusion was overthrown by laboratory tests in Hamburg later.

SEOUL, Aug. 31 (Xinhua) -- South Korea's infant mortality rate decreased by nearly half in the last 20 years to stand as the world's 16th lowest, a report showed Wednesday.South Korea had an infant mortality rate of 2.2 per 1,000 in 2009, compared with four deaths per 1,000 newborns reported in 1990, the World Health Organization (WHO) and Save the Children, an international non-governmental organization working for children's rights, said in a joint report.With a 45 percent decline in the infant mortality rate, South Korea ranked 16th lowest among WHO member countries, down from its 88th spot in 1990, according to the report. South Korea's infant mortality rate was the same as France, Estonia and Malta. Meanwhile, the Democratic People's Republic of Korea (DPRK) also showed a decline in the infant mortality rate from 23 per 1,000 in 1990 to 18.1 per 1,000 in 2009, but still remained in the lower ranks with 125th place.

LOS ANGELES, June 9 (Xinhua) -- The edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles approximately 100 million miles (160 million kilometers) wide, NASA's Jet Propulsion Laboratory (JPL) said on Thursday.The finding was based on observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, said JPL in Pasadena, Los Angeles.While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles which are created when magnetic field lines reorganize, said JPL.The new model suggests the field lines are broken up into self- contained structures disconnected from the solar magnetic field, according to JPL."The sun's magnetic field extends all the way to the edge of the solar system," said astronomer Merav Opher of Boston University. "Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt. Far, far away from the sun, where the Voyagers are, the folds of the skirt bunch up."Like Earth, our sun has a magnetic field with a north pole and a south pole. The field lines are stretched outward by the solar wind, a stream of charged particles emanating from the star that interacts with material expelled from others in our corner of the Milky Way galaxy.Understanding the structure of the sun's magnetic field will allow scientists to explain how galactic cosmic rays enter our solar system and help define how the star interacts with the rest of the galaxy.The Voyager spacecraft, more than nine billion miles (14 billion kilometers) away from Earth, are traveling in a boundary region. In that area, the solar wind and magnetic field are affected by material expelled from other stars in our corner of the Milky Way galaxy.Launched in 1977, the Voyager twin spacecraft have been on a 33- year journey. They are en route to reach the edge of interstellar space. JPL built the spacecraft and continues to operate them.

SAN FRANCISCO, June 8 (Xinhua) -- Facebook Inc. will be probed by European Union (EU) regulators over its latest facial recognition feature rolling out worldwide, U.S. media reported on Wednesday.The feature, called Tag Suggestions, uses face recognition software to match users' new photos to other photos they are tagged in. It groups similar photos together and suggests the name of the friend in the photos.Facebook rolled out the feature in the United States late last year, where users can opt out of the feature by going to their private settings. But Facebook switched it on by default without telling users first when it became available on Tuesday in countries outside of the United States.A group of privacy watchdogs from 27 EU nations will study the measure for possible rule violations, a Luxembourg official of Article 29 Data Protection Working Party told Bloomberg. The Working Party, an independent EU advisory body on data protection and privacy, comprises the data protection regulators of all the 27 EU member states."Tags of people on pictures should only happen based on people' s prior consent and it can't be activated by default," said the Luxembourg official, Gerald Lommel. He noted that such automatic features "can bear a lot of risks for users" and the European data- protection regulators will "clarify to Facebook that this can't happen like this."Authorities in Britain and Ireland said they are also looking into the new function on Facebook. The British Information Commissioner's Office told Bloomberg that "the privacy issues that this new software might raise are obvious," saying it is "speaking to Facebook" about the issue.Facebook has been under scrutiny by EU regulators for several privacy concerns, such as users' default settings and how the company uses the information collected from its social network website.
