BEIJING, March 11(Xinhuanet)-- People with more fat around their waist, often known as “apple shape”, may not have a greater risk of heart attack than those with fatter bottoms and hips, according to a new study published in Lancet as quotted by media reports Friday.This study funded by the Medical Research Council and British Heart Foundation, reviewed 220,000 individual records from 17 countries and monitored the occurrence of heart attacks or strokes based on body mass index (BMI) versus waist-hip circumference. It found that people with "apple-shaped" obesity were at a higher risk of having heart risks compared to those with general obesity as assessed by their BMI.  This contradicts previous claims that "apple shaped" bodies were three times more likely to suffer heart attacks than those with more generally distributed fat.But experts warn obesity is still bad for the heart, no matter where the fat is, and they argue there is confusion about the best way to measure it. "Regardless of how you measure it, being obese is bad for your heart. This study suggests that measuring your waist is no better than calculating your BMI but it's not time to throw away the tape measure just yet, “Dr Mike Knapton, associate medical director at the British Heart Foundation said."We tend to underestimate our body shape and size, so measuring our waist or checking our BMI are both quick and easy ways we can check our health at home."Besides, he also listed some other heart risk factors that we need to think about too, such as blood pressure, cholesterol, diabetes and smoking.

SAN FRANCISCO, March 8 (Xinhua) -- Google on Tuesday released a new stable version of its Chrome web browser, which the company said is speedier, simpler and safer."With today's stable release, even your most complex web apps will run more quickly and responsively in the browser," Tim Steele, a Google software engineer, said in a blog post announcing the release.The new version of Chrome features a simpler settings page that opens in a tab rather than a dialog box, and contains a search box showing users the settings they are looking for while they type.Users can also synchronize passwords in the browser across their computers, and will be able to encrypt those passwords for extra security.Google said that the latest Chrome browser provides additional layer of protection against malicious web pages, with the extended application of sandboxing technology.The browser can be downloaded for free, and current Chrome users will be automatically updated to the new version soon, Google said.

WASHINGTON, May 17 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced Tuesday that the international Aquarius/SAC-D observatory will be launched on June 9, to study interactions between ocean circulation, the water cycle and climate by measuring ocean surface salinity.Engineers at Vandenberg Air Force Base in California are performing final tests before mating the satellite to its Delta II rocket. The mission is a collaboration between NASA and Argentina' s space agency, with participation from Brazil, Canada, France and Italy.In addition to Aquarius, the primary instrument, the observatory carries seven other instruments that will collect environmental data for a wide range of applications, including studies of natural hazards, air quality, land processes and epidemiology.The mission will make NASA's first space observations of the concentration of dissolved salt at the ocean surface. Aquarius' observations will reveal how salinity variations influence ocean circulation, trace the path of freshwater around our planet, and help drive Earth's climate. The ocean surface constantly exchanges water and heat with Earth's atmosphere. Approximately 80 percent of the global water cycle that moves freshwater from the ocean to the atmosphere to the land and back to the ocean happens over the ocean.Salinity plays a key role in these exchanges. By tracking changes in ocean surface salinity, Aquarius will monitor variations in the water cycle caused by evaporation and precipitation over the ocean, river runoff, the freezing and melting of sea ice. Salinity also makes seawater denser, causing it to sink, where it becomes part of deep, interconnected ocean currents. This deep ocean "conveyor belt" moves water masses and heat from the tropics to the polar regions, helping to regulate Earth's climate."Salinity is the glue that bonds two major components of Earth' s complex climate system: ocean circulation and the global water cycle," said Aquarius Principal Investigator Gary Lagerloef of Earth & Space Research in Seattle in a statement. "Aquarius will map global variations in salinity in unprecedented detail, leading to new discoveries that will improve our ability to predict future climate."Aquarius will measure salinity by sensing microwave emissions from the water's surface with a radiometer instrument. These emissions can be used to indicate the saltiness of the surface water, after accounting for other environmental factors. Salinity levels in the open ocean vary by only about five parts per thousand, and small changes are important. Aquarius uses advanced technologies to detect changes in salinity as small as about two parts per 10,000, equivalent to a pinch (about one-eighth of a teaspoon) of salt in a gallon of water.Aquarius will map the entire open ocean every seven days for at least three years from 408 miles (657 kilometers) above Earth. Its measurements will produce monthly estimates of ocean surface salinity with a spatial resolution of 93 miles (150 kilometers). The data will reveal how salinity changes over time and from one part of the ocean to another.

ADDIS ABABA, Jan. 28 (Xinhua) -- Fruitful results have been achieved some one year after the fourth ministerial meeting of the Forum on China-Africa Cooperation (FOCAC), Chinese envoy and Assistant Foreign Minister Liu Zhenmin told Xinhua here on Friday.Liu was in the Ethiopian capital Addis Ababa to attend the 16th African Union (AU) summit as special envoy of the Chinese government.During the FOCAC ministerial meeting held in November 2009 in Sharm el-Sheikh, Egypt, the Chinese government announced eight new measures of promoting Sino-African cooperation.Since then, China has been actively implementing various programs and projects according to the eight new measures, Liu said.The “China-Africa Science and Technology Partnership Program” and the “China-Africa Joint Research and Exchange Program” have been launched, Liu said, adding that the aid program of agricultural demonstration center is in smooth implementation process.Meanwhile, China is actively working on establishing the China-Africa partnership in addressing climate change, and is strengthening communication and coordination with Africa on the issue of climate change, Liu said.The Chinese envoy added that various programs and events such as the China-Africa Agricultural Cooperation Forum, the “African Culture in Focus 2010” activities, and the “20+20 Cooperation Plan of Chinese and African Institutions of Higher Learning” have been launched or successfully held. He said these events have promoted the comprehensive development of China-Africa relations.A wide range of other measures are also being carried out in an active manner, according to Liu.The year 2011 is key to the implementation of the measures announced on the fourth ministerial meeting of FOCAC, Liu stressed.To this end, China will continue strengthening communication and coordination with African countries, carrying out close cooperation and pushing forward the development of the China-Africa new strategic partnership, he pledged.

BEIJING, Feb. 1 (Xinhua) -- Two Air China passenger planes carrying 457 Chinese citizens stranded in Egypt are due to arrive in Beijing early morning on Wednesday.The planes took off from the Cairo International Airport respectively at 11:16 and 15:32 local time (0916 and 1332 GMT) on Tuesday.The Civil Aviation Administration of China (CAAC), the nation's aviation authority, said Tuesday it was doing its best to organize flights to Egypt to bring home Chinese tourists stranded in the North African nation.China has arranged six flights to fly stranded Chinese nationals home, the CAAC said in a statement posted on its website.
