WASHINGTON, Nov. 10 (Xinhua) -- Using its near-infrared vision to peer nine billion years back in time, NASA's Hubble Space Telescope has uncovered an extraordinary population of young dwarf galaxies brimming with star formation, the U.S. space agency announced on Thursday.While dwarf galaxies represent the most common type of galaxy in the universe, the rapid star-birth observed in these newly- found examples may force astronomers to reassess their understanding of the ways in which galaxies form.The galaxies are a hundred times less massive, on average, than the Milky Way, yet they churn out stars at such a furious pace that their stellar content would double in just 10 million years. By comparison, the Milky Way would take a thousand times longer to double its star population.The universe is estimated to be 13.7 billion years old, and these newly-discovered galaxies are extreme even for the young universe -- when most galaxies were forming stars at higher rates than they are today. Astronomers using Hubble's instruments could spot the galaxies because the radiation from young, hot stars has caused the oxygen in the gas surrounding them to light up like a bright neon sign."The galaxies have been there all along, but up until recently astronomers have been able only to survey tiny patches of sky at the sensitivities necessary to detect them," said Arjen van der Wel of the Max Planck Institute for Astronomy in Germany, lead author of a paper on the results to be published online on Nov. 14 in The Astrophysical Journal. "We weren't looking specifically for these galaxies, but they stood out because of their unusual colors. "The observations were part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), an ambitious three- year study to analyze the most distant galaxies in the universe. CANDELS is the first census of dwarf galaxies at such an early epoch."In addition to the images, Hubble has captured spectra that show us the oxygen in a handful of galaxies and confirmed their extreme star-forming nature," said co-author Amber Straughn at NASA's Goddard Space Flight Center. "Spectra are like fingerprints. They tell us the galaxies' chemical composition."The CANDELS team uncovered the 69 young dwarf galaxies in near- infrared images taken with Hubble's Wide Field Camera 3 and Advanced Camera for Surveys.The observations suggest that the newly-discovered galaxies were very common nine billion years ago. However, it is a mystery why the newly-found dwarf galaxies were making batches of stars at such a high rate.

BEIJING, Jan. 15 (Xinhua) -- The winning of Ma Ying-jeou and Kuomintang (KMT) in Saturday's elections may open new chances for the peaceful development of cross-Strait relations.The results of the elections have indicated that the peaceful development of the cross-Strait relations is a correct path and has been widely recognized by the Taiwan people.Any persons and any political parties of Taiwan should follow this trend, so that they could earn recognition and support.Moreover, the victory of Ma and the KMT may represent a new opportunity for the development of the cross-Strait relations.With joint efforts of the two sides to fortify and enhance the existing mutual trust, there will be a even brighter prospect and further progresses in the cross-Strait talks, exchanges and cooperation.However, the two sides should be wary that the situation in the island is still complicated and the "Taiwan independence" stance will continue to haunt the cross-Strait relations development.There are still some long-term disputes and divergences existing between the two sides that await resolving.This year's elections were carried out under a background in which the cross-Strait relations have been significantly improved. The positive effects of the peaceful development of the cross-Strait relations have fully emerged.Over the past four years, the two sides of the Taiwan Strait have established a political mutual trust based on opposition to the "Taiwan independence" stance and adherence to the "1992 Consensus."The two sides resumed regular talks between the mainland's Association for Relations Across the Taiwan Straits (ARATS) and the Taiwan-based Straits Exchange Foundation (SEF) in 2008.The opening of "three direct links" of cross-Strait mail, trade, air and shipping services, has also pushed forward the cross-Strait economic cooperation into a brand-new stage.These achievements have brought about real benefits to the people on both sides of the Strait, especially the people in Taiwan.The cross-Strait economic cooperation has also helped the island's economy to buoy up from blows of the global financial crisis.The peaceful development of the cross-Strait ties have won a widespread support among the Taiwan people and it is also appreciated by the international community.During the election campaigns, whether to stick to the 1992 Consensus became a major field of cross fires among candidates. Ma had stood out and gained positive momentum with his cross-Strait policies.Numbers of Taiwanese notables, business tycoons as well as the small and medium-sized enterprise owners and the grassroots people have also expressed their stance for the "1992 Consensus" and their aspiration for further peaceful development of the cross-Strait ties.Under the public's pressure, the Democratic Progressive Party and its candidate Tsai Ing-wen have to lower their voices for "Taiwan independence."But their denial of the "1992 Consensus" and the stance of "one country on each side" could not abate the people's doubts and worries and finally led to their failure in the elections.Judged from the election, peaceful development of cross-Strait relations have developed from a concept to reality, benefitting people from different backgrounds and recognized by the public.

BEIJING, Nov. 28 (Xinhuanet) -- A majority of the emergency hospitalizations for bad events related to medication use in old U.S. adults stem from four common medications, according to a new study in the New England Journal of Medicine Monday.The study was conducted by researchers from the Centers for Disease Control and Prevention of U.S.There are nearly 100,000 emergency hospitalizations for adverse drug events in older Americans, says researcher Daniel S. Budnitz, MD, MPH, director of the CDC's Medication Safety Program.And the four types of medication -- two for diabetes and two blood-thinning agents -- account for two-thirds of those drug-related emergency hospitalizations. They most often cited: warfarin (Coumadin, Jantoven); insulin; antiplatelet drugs such as aspirin and clopidogrel (Plavix); oral hypoglycemic agents."Both blood thinners and diabetes medicines are critical drugs that can be lifesaving," Budnitz says.However, he says that ''these are medications that you do need to pay attention to," being sure the dose and timing are correct, among other measures.

SAN FRANCISCO, Nov. 7 (Xinhua) -- Google on Monday added a highly-anticipated service to its Google+ social network, allowing businesses and brands to set up their own pages on the site.Named "Google+ Page," the service is a further challenge to its rival Facebook's fan pages, which has become a major promotion strategy for many business brands over the past several years.Unlike Facebook, Google will not charge businesses and organizations for using the scheme, and will not put ads on the pages. The service is expected to enhance the tech giant's other businesses like search and mobile advertising.Some big brand names, such as Burberry, the Barcelona football club and the Muppets, have already set up their pages.Google noted it will not pass on personal data.In addition to big brands, Google also wants small businesses that have or do not have their own websites to use Google+ Pages as their default presences.According to a report by Ad Age Digital, Google+ Pages will soon be location-aware, allowing local businesses to send offers and deals to mobile phones.According to Google, more than 40 million people have opened an account with its social network, which was launched in June. Although the network is growing very quickly, some analysts said it still has a long way to go to become a major threat to Facebook, which has more than 800 million users.

SAN FRANCISCO, Dec. 29 (Xinhua) -- The United States Patent and Trademark Office on Thursday published a patent application from Apple related to face and presence detection for iOS devices, which is expected to be one of the next chapters for mobile security.According to AppleInsider, a news and rumor website focusing on Apple, the patent is entitled "low threshold face recognition" which is a low-computation solution for quickly and accurately recognizing a user on iPhone, iPad, iPod Touch and MacBook.Patently Apple, a blog focusing on Apple's latest intellectual properties, said that iOS devices would acknowledge the presence of the potential user by turning on the display and then trigger a subsequent process for recognizing the potential user's face.Currently, most face recognition systems tend to be robust ones working in various lighting conditions, orientations, scale and etc., which will require computing resources and drain battery life. There are also security-type face recognition systems working under controlled lighting conditions which could be ineffective due to factors like proximity of the user to the camera.Google's latest Android 4.0 operating system, codenamed Ice Cream Sandwich, already features face detection. But it is reported that the feature doesn't always work and can be bypassed by using a photograph of the phone's owner.Apple's solution would reduce the impact of lighting conditions and biometric distortions on an image, said AppleInsider, citing the filing. Apple said it would rely on a "high information portion" of a human face, such as eyes, mouth or the tip of a user 's nose.The "likely presence" of a human face in front of the camera would be captured through an "orange-distance filter" which would also be used to detect the potential user's skin tone and measure the distance of their face from the camera.Meanwhile, iOS devices could also be set to recognize faces of multiple users, presenting each user with a personalized configuration.According to AppleInsider, the patent application was first filed by Apple in June, 2009.Analysts said that the proposed technology could be Apple's next big innovation as it has record of redesign and give its unique appeal to products that have not caught on with the general public.
