MOSCOW, Aug. 3 (Xinhua) -- Two Russian cosmonauts manually launched a mini satellite from the International Space Station ( ISS) during a six-hour spacewalk Wednesday, said the Mission Control center near Moscow.Sergei Volkov and Alexander Samokutyayev, who started the spacewalk with a 20-minute delay, found the 30-kg Kedr has lost one of its two antennas during its delivery to the ISS in January. After consulting with the Mission Control, they have decided to launch the device anyway, Interfax news agency reported.The Kedr satellite, which was made by Russian students, was created to transmit from the orbit greetings in 15 languages about the 50th anniversary of Yuri Gagarin's first space flight. It could also photograph the Earth and re-transmit information from the ISS equipment.During the spacewalk, the cosmonauts were expected to install new stream video equipment on the station's outer surface, and to take pictures holding photos of the founders of Russian space explorations, including Konstantin Tsiolkovski, Sergei Korolyov and Yuri Gagarin.

SAN FRANCISCO, Aug. 2 (Xinhua) -- Social networking giant Facebook on Tuesday announced that it has bought Push Pop Press, a digital publishing company that develops the technology to help make interactive books optimized for iPad and other Apple devices."We're thrilled to confirm that we've acquired Push Pop Press, a startup whose groundbreaking software changes the way people publish and consume digital content," Facebook said in a statement.Push Pop Press was co-founded by Mike Matas and Kimon Tsinteris, both former Apple employees, and was known for teaming up with former U.S. vice president Al Gore to create a digital version of his book "Our Choice"."Although Facebook isn't planning to start publishing digital books, the ideas and technology behind Push Pop Press will be integrated with Facebook, giving people even richer ways to share their stories," Push Pop Press said in a statement posted on its website."With millions of people publishing to Facebook each day, we think it's going to be a great home for Push Pop Press," the statement added.Financial terms of the deal were not disclosed by the two companies.

SAN FRANCISCO, Aug. 23 (Xinhua) -- The amount of malware targeted at devices based on Google's Android platform surged 76 percent in the second quarter over the previous three months in 2011, making it the most attacked mobile operating system, computer security firm McAfee said on Tuesday.A new McAfee study found that in the second quarter, Android- based malware surpassed Nokia's Symbian as the most popular target for mobile malware developers.While Symbian and Java ME, a platform designed for mobile devices and other embedded systems, remain the most targeted to date, the rapid rise in Android malware indicates that the platform could become an increasing target for cyber criminals McAfee said.Models pose with the new Samsung Galaxy S Android smartphone during its launch ceremony at the headquarters of Samsung Electronics in Seoul in this June 8, 2010 file photograph.It warned that the attacks on Android platform could affect everything from calendar apps, to text messages, and even a fake Angry Birds updates.According to the study, malware on mobile platforms is increasing steadily, often mimicking the same code as personal computer-based threats, as vast amount of personal and business data are now found on user's smartphones and other mobile devices."This year we've seen record-breaking numbers of malware, especially on mobile devices, where the uptick is in direct correlation to popularity," Vincent Weafer, senior vice president of McAfee Labs, said in a statement."Overall attacks are becoming more stealth and more sophisticated, suggesting that we could see attacks that remain unnoticed for longer periods of time," he noted.

WASHINGTON, June 6 (Xinhua) -- The tropics and much of the Northern Hemisphere are likely to experience an irreversible rise in summer temperatures within the next 20 to 60 years if atmospheric greenhouse gas concentrations continue to increase, according to a new climate study by Stanford University scientists. The results will be published later this month in the journal Climatic Change.In the study, the Stanford team concluded that many tropical regions in Africa, Asia and South America could see "the permanent emergence of unprecedented summer heat" in the next two decades. Middle latitudes of Europe, China and North America -- including the United States -- are likely to undergo extreme summer temperature shifts within 60 years, the researchers found."According to our projections, large areas of the globe are likely to warm up so quickly that, by the middle of this century, even the coolest summers will be hotter than the hottest summers of the past 50 years," said the study's lead author, Noah Diffenbaugh, an assistant professor of environmental Earth system science and fellow at the Woods Institute for the Environment at Stanford. The study is co-authored by Stanford research assistant Martin Scherer."When scientists talk about global warming causing more heat waves, people often ask if that means that the hottest temperatures will become 'the new normal,'" Diffenbaugh said. " That got us thinking -- at what point can we expect the coolest seasonal temperatures to always be hotter than the historically highest temperatures for that season?"To determine the seasonal impact of global warming in coming decades, Diffenbaugh and Scherer analyzed more than 50 climate model experiments -- including computer simulations of the 21st century when global greenhouse gas concentrations are expected to increase, and simulations of the 20th century that accurately " predicted" the Earth's climate during the last 50 years. The analysis revealed that many parts of the planet could experience a permanent spike in seasonal temperatures within 60 years."We also analyzed historical data from weather stations around the world to see if the projected emergence of unprecedented heat had already begun," Diffenbaugh said. "It turns out that when we look back in time using temperature records, we find that this extreme heat emergence is occurring now, and that climate models represent the historical patterns remarkably well."According to both the climate model analysis and the historical weather data, the tropics are heating up the fastest. "We find that the most immediate increase in extreme seasonal heat occurs in the tropics, with up to 70 percent of seasons in the early 21st century (2010-2039) exceeding the late-20th century maximum," the authors wrote.Tropical regions may see the most dramatic changes first, but wide swaths of North America, China and Mediterranean Europe are also likely to enter into a new heat regime by 2070, according to the study.This dramatic shift in seasonal temperatures could have severe consequences for human health, agricultural production and ecosystem productivity, Diffenbaugh said. As an example, he pointed to record heat waves in Europe in 2003 that killed 40,000 people. He also cited studies showing that projected increases in summer temperatures in the Midwestern United States could reduce the harvest of staples, such as corn and soybeans, by more than 30 percent.

BEIJING, July 25 (Xinhuanet) -- More than one in three births in the U.S. are  delivered by C-section, which is an all time high and an increase of 25 percent over seven years, according to news reports Monday quoting a new study.Based on data from 19 states, C-section, or Cesarean, deliveries shot up from 27 percent of all births in 2002 to 34 percent in 2009, said the study by HealthGrades.  HealthGrades is an independent health care ratings organization with information on physicians, dentists and 5,000 hospitals in the nation.The study noted that the states with the highest rates are Texas, New Jersey and Florida while Utah, Colorado and Wisconsin are the lowest.Experts hold C-section deliveries are most suitable when vaginal delivery puts the health of the woman or child at risk, but also attributing the reason of increase to convenience, less risk, fertility and general attitudes.However, Divya Cantor, MD, MBA and HealthGrades Senior Physician Consultant. cautioned, "C-sections are rising, and there needs to be a little bit more scrutiny from the person who is having the C-section as well as doctors and hospitals."
