SAN FRANCISCO, June 15 (Xinhua) -- Facebook has hired Joe Lockhart, who was former U.S. President Bill Clinton's press secretary during the last two years of his second term, as the social network company's vice president of global communications, U.S. media reported on Wednesday.Lockhart, 51, will report to Elliot Schrage, Facebook's current vice president of global communications, marketing and public policy, The Wall Street Journal said in a report."His experience building and running a press office at the White House gives him particular appreciation for the demands of a global 24-hour news cycle and the challenges of responding effectively to intense scrutiny," Schrage said of Lockhart's arrival.Lockhart will start at Facebook on July 15 and will move from Washington D.C. to Facebook's headquarters in California.Lockhart is the latest Washington insider to join Facebook as the world's largest social networking site is facing intense scrutiny for its privacy practices and growing global presence, The Wall Street Journal pointed out.Last year, Facebook also hired White House economic adviser Marne Levine to serve as its vice president of global public policy.More recently, Facebook hired former Bush administration officials Joel Kaplan as its vice president for U.S. public policy, and Myriah Jordan, who will become a policy manager focusing on congressional relations.

THE HAGUE, Aug. 16 (Xinhua) -- ESBL-enzymes, which are known for their ability to stop the effects of antibiotics, can directly pass from chicken to people, said a research published on Tuesday.Veterinary researcher Dik Mevius of the Wageningen University released the finding in the magazine Resource.The research group led by Mevius has isolated six ESBL-genes varieties and compared them to bacteria found on hospital patients, on super market poultry and in laying batteries. In 35 percent of all cases, they discovered a match of 100 percent.Bacteria like Klebsiella on E. coli can produce the ESBL-enzymes. A healthy person will not feel any effect, but people with a lower immune system can get very sick. In areas like a hospital, the infection can easily spread."The main concern is that the enzyme resists the most used antibiotics, which makes the treatment of infected persons difficult," said Mevius.According to Mevius, 94 percent of supermarket poultry carries the enzyme, but all enzymes will be killed during the heating process of cooking.

WASHINGTON, Aug. 3 (Xinhua) -- The annual number of new HIV infections in the United States was relatively stable at approximately 50,000 new infections each year between 2006 and 2009, the Centers for Disease Control and Prevention's first multi- year estimates from its national HIV incidence surveillance find.However, HIV infections increased among young men who have sex with men (MSM) between 2006 and 2009, driven by alarming increases among young, black MSM -- the only subpopulation to experience a sustained increase during the period.According to the new estimates, there were 48,600 new HIV infections in the United States in 2006, 56,000 in 2007, 47,800 in 2008 and 48,100 in 2009. The multi-year incidence estimates allow for a reliable examination of trends over time. They reveal no statistically significant change in HIV incidence overall from 2006 to 2009, with an average of 50,000 for the four-year period. In 2009, the largest number of new infections was among white MSM (11,400), followed closely by black MSM (10,800). Hispanic MSM (6, 000) and black women (5,400) were also heavily affected.The new estimates were published Wednesday in the on-line scientific journal PLoS ONE."More than 30 years into the HIV epidemic, about 50,000 people in this country still become infected each year. Not only do men who have sex with men continue to account for most new infections, young gay and bisexual men are the only group in which infections are increasing, and this increase is particularly concerning among young African American MSM," said CDC Director Thomas Frieden. " HIV infections can be prevented. By getting tested, reducing risky behaviors, and getting treatment, people can protect themselves and their loved ones."

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."

SAN FRANCISCO, June 28 (Xinhua) -- Google Android chief Andy Rubin said on Tuesday that the activations of Android-powered devices are growing at a rate of 4.4 percent on a weekly basis, with over 500,000 devices activated each day worldwide."There are now over 500,000 Android devices activated every day, and it's growing at 4.4 percent w/w," tweeted Rubin, Google's Senior Vice President of Mobile who oversees the development of Android, the open-source operating system for smartphones.Last month, Google said at its annual developer conference Google I/O that 400,000 Android devices were being activated each day, compared with 300,000 daily activations in December and 100, 000 in May 2010.More research data have shown Android system's soaring market share and popularity. Earlier this month, Internet market research company ComScore reported that Android remained the No. 1 smartphone operating system in the United States over the three months ending in April. The system captured 36.4 percent of U.S. smartphone subscribers, while Apple's iOS system for iPhone had 26 percent of all smartphone users.In April, market research company Gartner said in a forecast that the Android operating system will own 49.2 percent of the global smartphone market and Apple's iOS will have an 18.9-percent share in the second place.
