CHONGQING, May 28 (Xinhua) -- Non-infectious chronic diseases have become the major threat to human health in China as deaths from such diseases account for 85 percent of annual total deaths in the country, a report issued Saturday warned.The report said a 2008 national survey on mortality cause in China showed that the figure was up from 53 percent in 1973. Such diseases result in 3.7 million deaths annually.The Disease Prevention and Control Bureau under the Ministry of Health, and the Chinese Center for Disease Control and Prevention conducted the study, which was released at a national forum on prevention and control of chronic diseases in Chongqing.The mortality-cause survey shows that four non-infectious chronic diseases -- Cerebrovascular disease, cancer, respiratory disease and heart disease -- are the four principal causes that led to the largest number of deaths in China.Chronic diseases are the leading cause of mortality in the world, accounting for 60 percent of all deaths, reports the World Health Organization.According to the report, changes in lifestyle is one of the reasons that chronic diseases are increasing. Food with high contents of fat, protein and salt can lead to high blood pressure, high blood-fat and high blood sugar. Meanwhile, more people ride in vehicles instead of walking, meaning they exercise less.Experts at the forum called for more efforts to prevent and treat chronic diseases."It allows no delay," Kong Lingzhi, the vice director of the Disease Prevention and Control Bureau said, underlining the importance of reinforcing public education on chronic disease prevention and control."The earlier patients are aware of chronic diseases and receive proper medical treatment, the more likely they could overcome the diseases," she said.According to Kong, China has set a strategy to cope with chronic diseases in which government assumes the main responsibility, while the focus is on prevention.She said China would work to establish a prevention mechanism that pools the efforts of households, communities, professional institutions, and society at large.

BEIJING, Aug. 1 (Xinhua) -- The provinces of Guizhou and Hunan reported their lowest levels of precipitation since 1951 in July, the China Meteorological Administration (CMA) said on Monday.Precipitation levels across the country saw a decrease of 8.7 percent from the average level of 115.9 mm in July, the lowest levels seen in 11 years, said Chen Zhenlin, an expert with the CMA.The average temperature recorded across the country in July was 22.1 degrees Celsius, up 0.7 degrees Celsius from the average level.

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.

CANBERRA, Sept. 24 (Xinhua) -- Australian scientists on Saturday said a satellite due to re-enter Earth poses a negligible threat to life and property on Earth.U.S. National Aeronautics and Space Administration's Upper Atmosphere Research Satellite (UARS), which weighs more than five tons, is expected to re-enter the Earth's atmosphere at 1058 (AEST) on Saturday. The U.S.-based Center for Orbital and Re-entry Debris Studies estimates that re-entry could occur up to seven hours before or after this time.According to Nonathan Nally, a former editor of two space magazines and currently editor of the Australian Space News website, the satellite poses a negligible threat to life and property on Earth."Most of the satellite will burn up on re-entry, with perhaps as many as 26 stronger or harder small pieces surviving to reach the surface," Nally said in a statement."But with the majority of the Earth comprising oceans or uninhabited (or very sparsely populated) remote regions, the chances are overwhelming that any pieces of UARS that survive re- entry will fall harmlessly and never be seen again."Since the spacecraft is no longer powered, U.S. National Aeronautics and Space Administration has no control over where it comes down, but Nally said there is a small chance that debris from the satellite could land in Australia.Debris from SkyLab, another satellite which plunged to Earth, was scattered over parts of Western Australia in 1979. Skylab weighed about 77 tonnes, many times more than the UARS.?Dr Alice Gorman, a lecturer in the Department of Archaeology, specializing in space archaeology, at Flinders University in South Australia, said the UARS satellite re-entry is very reminiscent of Skylab in 1979."There is the same exaggeration of the hazard through the media, public anxiety as the advance warning allows for speculation, and a lack of understanding of what the risks actually are," he said in a statement."Should it land in Australia, we might expect the same rush for souvenirs as we saw with Skylab, as anything that has been in space has a special meaning on Earth."?UARS was launched on 12 September 1991 and decommissioned on 15 December 2005. Its total dry mass is about 5.5 tonnes. UARS is one of the largest NASA satellites to plunge back to Earth uncontrolled in the last 30 years.Since the beginning of the Space Age in the late-1950s, there have been no confirmed reports of an injury resulting from re- entering space objects.? Nor is there a record of significant property damage resulting from a satellite re-entry.

SAN FRANCISCO, Aug. 15 (Xinhua) --- Google Inc. on Monday announced that it has agreed to buy Motorola Mobility Holdings Inc. for about 12. 5 billion U.S. dollars, the largest purchase for the Internet search giant that will allow it to compete more directly with other mobile phone makers.Google said that it will acquire Motorola Mobility for 40 dollars per share in cash, or a total of about 12.5 billion dollars, a premium of 63 percent to the closing price of Motorola Mobility shares last Friday.The transaction was unanimously approved by the boards of directors of both companies and is expected to close by the end of 2011 or early 2012, subject to regulatory approvals and other closing conditions.Google noted that the acquisition of Motorola Mobility, a dedicated partner of its Android mobile operating system, will enhance competition in mobile computing.Motorola Mobility will remain a licensee of Android and Android will remain open, Google said, adding that it will run Motorola Mobility as a separate business."Motorola Mobility's total commitment to Android has created a natural fit for our two companies. Together, we will create amazing user experiences that supercharge the entire Android ecosystem for the benefit of consumers, partners and developers," Larry Page, Google's chief executive officer (CEO), said in a statement."We have shared a productive partnership with Google to advance the Android platform, and now through this combination we will be able to do even more to innovate and deliver outstanding mobility solutions across our mobile devices and home businesses," said Sanjay Jha, CEO of Motorola Mobility.
