SAN FRANCISCO, June 28 (Xinhua) -- Google on Tuesday rolled out a new social networking service named "Google+", a long awaited move of the Internet search giant to crack the industry's social trend dominated by Facebook.Unlike Facebook, Google said that the project is designed for sharing with small groups like college roommates and parents. " Today's online services turn friendship into fast food, wrapping everyone in 'friend' paper," Google said in a blog post announcing the new service.Other Google+ features include Sparks, which gathers articles and videos on topics of interests or hobbies; and Hangouts, which allows users join live multi-person video chat.There is also a mobile version of Google+ for smartphones running Google's Android operating system, which enables multi- person text message chats and instant upload of photos from the phone.The Google+ project is currently in field trial and by invitation only. Users can select people from their Gmail contacts and organize them into different groups.Google+ is expected to test whether Google could come back from its past frustration in social networking, such as Buzz, a social networking and messaging too integrated into its Gmail service. Some of Google Buzz's features have been widely criticized for privacy concerns.Market research data show that Facebook has surpassed Google in terms of time spent on each site, a fact that advertisers attach importance to.According to Internet market research company comScore, including YouTube, 180 million people visited Google sites in May, compare to 157.2 million on Facebook. However, Facebook users looked at 103 billion pages and spent an average of 375 minutes on the site, while Google users viewed 46.3 billion pages and spent 231 minutes.In April, Google CEO and co-founder Larry Page reportedly sent out a company-wide memo alerting employees that 25 percent of their annual bonus will be tied to the success or failure of Google's social strategy in 2011.

ULAN BATOR, Aug. 2 (Xinhua) -- The Mongolian government has confirmed equine influenza, a disease that mainly affects horses, broke out in 14 provinces.The government's news office announced the confirmation Tuesday after suspected cases were recently discovered in 18 provinces of the country, where horses still play a key role.According to a Mongolian government report, Mongolian Vice Premier M. Enkhbold called a state emergency situation committee meeting on Monday to respond to the epidemic.Millions of horses will need to be vaccinated, given cases of the disease have been discovered in all but three provinces -- Bayan-Ulgii, Zavkhan and Umnugobi.Equine influenza usually broke out in spring and fall, said an official of the Mongolian veterinarian and breeding bureau. He urged vaccination to be carried out as soon as possible.Mongolia has experienced several equine influenza outbreaks in the past few decades. Outbreaks in Khovd province in 2007 and 2008 caused huge losses to the local livestock industry.Animal husbandry is a dominant factor in the agriculture sector of Mongolia, which has more than 40 million livestock, 2 million of which are horses.

WASHINGTON, June 21 (Xinhua) -- Brain cancer patients who are able to exercise live significantly longer than sedentary patients, U.S. scientists at the Duke Cancer Institute have reported.The finding, published online this week in the Journal of Clinical Oncology, adds to recent research that exercise improves how cancer patients feel during and after treatments, and may also extend their lives.The study enrolled 243 patients with advanced recurrent gliomas, lethal brain malignancies that typically result in a median life expectancy of less than six months. The patients who reported participating in regular, brisk exercise -- the equivalent of an energetic walk five days a week for 30 minutes -- had significantly prolonged survival, living a median 21.84 months versus 13.03 months for the most sedentary patients."This provides some initial evidence that we need to look at the effects of exercise interventions, not only to ease symptoms but also to impact progression and survival," said Lee Jones, associate professor in the Duke Cancer Institute and senior author of the study.

NAIROBI, Aug. 18 (Xinhua) -- The World Health Organization (WHO) on Thursday decried increased number of confirmed cholera cases in the Somalian capital Mogadishu, and growing reports of acute watery diarrhea in Kismayo and other crowded urban centers, saying an urgent multi-sector response to contain the spread of this highly contagious disease is being mounted.The UN health agency said has confirmed cholera in Banadir, Bay, Mudug and Lower Shabelle regions and the number of acute watery diarrhea cases has increased dramatically in the last few months.WHO Representative for Somalia Marthe Everard said combination of poor sanitation conditions, a shortage of safe water, overcrowding and high malnutrition rates, creates the perfect combination for infectious diseases, such as cholera and pneumonia, to spread and increase the number of deaths. "For the last few years, a network of health workers reporting to the early warning system is in place, however they report through a health facility or mobile clinic. Yet the large numbers of displaced people in Mogadishu are making it more difficult to record the various diseases," Everard said in a statement issued in Nairobi. "We urgently need more mobile clinics that will provide basic health care services to the many displaced and who will strengthen the reporting on new outbreaks. This is critical to our response and our ability to save lives."According to WHO, about seventy-five percent of all cases of acute watery diarrhea are children under the age of five.Since January this year, 4,272 cases of acute watery diarrhea/ cholera have been reported in Banadir Hospital in Mogadishu alone. However, at this stage most of the cholera cases in the various regions are contained and under control. "Our major concern is to monitor and detect new disease outbreaks in the many informal settlements set up by internally displaced people in and around Mogadishu", says Everard.Although cholera is endemic in the country, the last major cholera outbreak was in 2007 with an estimated 67,000 cases.WHO said recent efforts to cholrinate the water supply of Mogadishu, along with efforts to improve hygiene and sanitation have prevented a serious outbreak but with the large influx of some 100,000 people alone this year into Mogadishu, bringing the total number of IDPs in the capital to an estimated 470,000, many are living in overcrowded settlements, there is an acute shortage of safe water and adequate sanitation. "There is no need for a child to die of diarrhea, yet this is tragic reality for a Somali child, who is acutely malnourished. It is a lethal combination." said Rozanne Chorlton, UNICEF Representative for Somalia. "These types of diseases can be prevented and treated quickly, but to save children's lives we need to make sure safe water, sanitation and hygiene along with early access to primary health care, are an integral part of our emergency response."WHO said partners in the health and water and sanitation sectors are currently preparing for a potential 100,000 cholera cases including 80,000 moderate cases and 20,000 severe cases.Emergency diarrheal disease kits made up of medical supplies such as syringes, infusions, and oral rehydration fluids (ORS), already prepositioned by UNICEF and WHO have been sent to 13 hospitals.An additional 200 diarrheal disease kits, each able to treat 100 severe cases and 400 moderate cases are being procured and should be in Southern Somalia in the next few weeks, it said.In addition, WHO said, the case management of severe dehydration with and without malnutrition is being strengthened and focus is now on mobilizing a network of already trained community health promoters to move from door to door with health hygiene education messages. "Health posts will be stocked with essential medicines and ORS to identify and promptly treat patients. Many of Southern Somalia' s rural areas and urban centers rely on shallow wells, which unless protected or treated with chlorine can serve as the perfect breeding ground for water borne diseases," it said.To respond to this threat and prevent a major outbreak, the UN health agency said partners in the water, sanitation and hygiene sector are scaling up their actions to target 1.5 million people across high risk areas of the south.Supplies of chlorine and essential items for hygiene and household treatment and storage of water are being distributed.Already 217 water sources are being chlorinated and 58 water point outlets benefitting 483,200 residents and internally displaced people in Mogadishu.In addition, household hygiene supplies, including water purification tablets, soap and buckets, enough for 48,000 families, are being distributed at existing feeding centers for malnourished children.Campaigns to educate families about the treatment of drinking water, safe disposal of waste and encourage hand washing with soap will also be scaled up in high risk communities.As part of the updated 2011 UN Consolidated Appeal for Somalia, an estimated 80 million U.S. dollars is needed for the health sector and 78 million dollars is required for the water, sanitation and hygiene sector.So far, each sector has respectively raised 30 percent and 37 percent of the required money.

WASHINGTON, July 27 (Xinhua) -- Astronomers studying observations taken by NASA's Wide-field Infrared Survey Explorer (WISE) mission have discovered the first known "Trojan" asteroid orbiting the sun along with Earth, the U.S. National Aeronautics and Space Administration (NASA) announced Wednesday in a statement.Trojans are asteroids that share an orbit with a planet near stable points in front of or behind the planet. Because they constantly lead or follow in the same orbit as the planet, they never can collide with it. In our solar system, Trojans also share orbits with Neptune, Mars and Jupiter. Two of Saturn's moons share orbits with Trojans.Scientists had predicted Earth should have Trojans, but they have been difficult to find because they are relatively small and appear near the sun from Earth's point of view."These asteroids dwell mostly in the daylight, making them very hard to see," said Martin Connors of Athabasca University in Canada, lead author of a new paper on the discovery to be published Thursday in the journal Nature. "But we finally found one, because the object has an unusual orbit that takes it farther away from the sun than what is typical for Trojans. WISE was a game-changer, giving us a point of view difficult to have at Earth 's surface."The WISE telescope scanned the entire sky in infrared light from January 2010 to February 2011. Connors and his team began their search for an Earth Trojan using data from NEOWISE, an addition to the WISE mission that focused in part on near-Earth objects, or NEOs, such as asteroids and comets. NEOs are bodies that pass within 28 million miles (45 million kilometers) of Earth 's path around the sun. The NEOWISE project observed more than 155, 000 asteroids in the main belt between Mars and Jupiter, and more than 500 NEOs, discovering 132 that were previously unknown.The team's hunt resulted in two Trojan candidates. One called 2010 TK7 was confirmed as an Earth Trojan after follow-up observations with the Canada-France-Hawaii Telescope on Mauna Kea in Hawaii.The asteroid is roughly 1,000 feet (300 meters) in diameter. It has an unusual orbit that traces a complex motion near a stable point in the plane of Earth's orbit, although the asteroid also moves above and below the plane. The object is about 50 million miles (80 million kilometers) from Earth. The asteroid's orbit is well-defined and for at least the next 100 years, it will not come closer to Earth than 15 million miles (24 million kilometers).
