BEIJING, July 17 (Xinhua) -- China's land prices in 105 cities rose 1.87 percent on average in the second quarter over the first, but the rate of growth slowed, the China Urban Land Price Dynamic Monitor, a land price information provider, announced Sunday. < In the second quarter, land price for business properties averaged 5,506 yuan (about 847 U.S. dollars) per square meter, up 2.77 percent from the previous quarter. The growth rate slowed by 0.56 percentage points.Land price for residential properties averaged 4,443 yuan per square meter, up 2.17 percent. The growth slowed by 0.27 percentage points. The price for industrial uses, meanwhile, was up 1.13 percent to reach 645 yuan per square meter. The growth fell 0.3 percentage points.The country's three most prosperous regions, the Yangtze River Delta Region, Pearl River (Zhujiang) Delta Region, and the Bohai Rim, all reported slower land price growth in the second quarter.

BEIJING, July 15 (Xinhua) -- The Chinese Academy of Agricultural Sciences (CAAS) announced Friday that a group of international scientists has finished sequencing the genetic code of the potato.The Potato Genome Sequencing Consortium (PGSC), which is led by Chinese scientists and made up of 97 researchers from 14 countries, has sequenced the complete potato genome and published a report of its findings in the latest issue of the scientific journal Nature, said the CAAS.The research took six years and revealed that the potato contains about 39,000 genes, said the CAAS.Qu Dongyu, a potato farming specialist with the Crop Science Society of China and a promoter of the PGSC, said the study helped discover genes that define the growth and insect resistance of potatoes.The sequenced genome will enable scientists to create new varieties of potato that are high in yield and quality and more resistant to insects and diseases, he said.Huang Sanwen, a researcher with the CAAS and one of the three corresponding authors of the report, said the sequencing will also allow potato breeders to accelerate the breeding process of new seeds from 10 to 12 years to about 5 years.China is the world's top potato grower, with its farmers planting potatoes on nearly 90 million mu (6 million hectares) of land each year. The average yield per mu stands at 1,000 kg, only one-third of that harvested by countries with advanced technologies, Qu said.

SAN FRANCISCO, June 1 (Xinhua) -- Microsoft on Wednesday gave a preview of its next-generation operating system code-named "Windows 8."The software giant introduced the successor to Windows 7 at the ninth edition of The Wall Street Journal's Digital: All Things Digital in Rancho Palos Verdes, California, some 48 km south of Los Angeles.With an interface quite different from legacy Windows, Windows 8 looks more like Windows Phone 7 and features an app management from Windows mobile operating system. It is the first major attempt by Microsoft to expand a mobile operating system to desktop status, and is expected to be touch-friendly and work seamlessly on desktops, laptops and tablet computers.For legacy Windows users, they need to swipe up from the bottom of the screen to get to the Windows 7-based view. Microsoft said the new system will be compatible with all Windows 7 logo PCs, software and peripherals.During the demonstration, Steven Sinofsky, Microsoft's head of Windows, also said the importance of not abandoning the established technologies from the traditional PC. "The mouse and the keyboard aren't evil. They're just tools. There are a number of applications that require the greater precision offered by the mouse." said Sinofsky.Sinofsky did not say when Windows 8 would be available.Although there are some tablets running Microsoft's current Windows 7 operating system, the software giant has been criticized for failing to adequately respond to the fast growth of tablet computers, like Apple's iPad.

BUJUMBURA, May 31(Xinhua) -- As the World No Tobacco Day is celebrated on Tuesday, many Burundians feel happy that they have given up smoking thanks to herbal drugs.Evariste Ndikumwami, 55, residing in the Burundian capital Bujumbura, said he had been smoking for 30 years, but gave up smoking in January after taking herbal drugs prescribed by an abbot."I had been smoking since my teenage and I gave up smoking in January (this year) after I took herbal drugs that I got from a Roman Catholic priest from Uganda working at Rugari parish in the province of Muyinga, some 210 km northeast of the Burundian capital Bujumbura," Ndikumwami told Xinhua.Ndikumwami said he used to smoke a pack of 20 cigarettes per day, adding that he had found it hard to give up smoking.He said, "I took the herbal drugs for 15 days. The abbot prescribed me two herbal drugs -- one to be smoked for five days at daytime when I desire to smoke and another one to be applied around the nostrils at night."After the medication period, he never felt the desire for smoking cigarettes, he said."When my friends realized I was no longer smoking, they asked me which drugs I took to give up smoking. I directed them to the abbot who had healed me and they also got cured and stopped smoking," Ndikumwami said.

LOS ANGELES, July 22 (Xinhua) -- Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe, NASA's Jet Propulsion Laboratory (JPL) said on Friday.The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away, according to JPL in Pasadena, California."The environment around this quasar is very unique in that it's producing this huge mass of water," said Matt Bradford, a scientist at JPL. "It's another demonstration that water is pervasive throughout the universe, even at the very earliest times. "This artist's concept illustrates a quasar, or feeding black hole, similar to APM 08279+5255, where astronomers discovered huge amounts of water vapor. Gas and dust likely form a torus around the central black hole, with clouds of charged gas above and below. X-rays emerge from the very central region, while thermal infrared radiation is emitted by dust throughout most of the torus. While this figure shows the quasar's torus approximately edge-on, the torus around APM 08279+5255 is likely positioned face-on from our point of view.A quasar is powered by an enormous black hole that steadily consumes a surrounding disk of gas and dust. As it eats, the quasar spews out huge amounts of energy. Both groups of astronomers studied a particular quasar called APM 08279+5255, which harbors a black hole 20 billion times more massive than the sun and produces as much energy as a thousand trillion suns.Astronomers expected water vapor to be present even in the early, distant universe, but had not detected it this far away before. There's water vapor in the Milky Way, although the total amount is 4,000 times less than in the quasar, because most of the Milky Way's water is frozen in ice. Water vapor is an important trace gas that reveals the nature of the quasar. In this particular quasar, the water vapor is distributed around the black hole in a gaseous region spanning hundreds of light-years in size (a light-year is about six trillion miles).Its presence indicates that the quasar is bathing the gas in X- rays and infrared radiation, and that the gas is unusually warm and dense by astronomical standards, JPL said.Although the gas is at a chilly minus 63 degrees Fahrenheit ( minus 53 degrees Celsius) and is 300 trillion times less dense than Earth's atmosphere, it's still five times hotter and 10 to 100 times denser than what's typical in galaxies like the Milky Way, said JPL.Measurements of the water vapor and of other molecules, such as carbon monoxide, suggest there is enough gas to feed the black hole until it grows to about six times its size, JPL said.Whether this will happen is not clear, the astronomers say, since some of the gas may end up condensing into stars or might be ejected from the quasar.Bradford's team made their observations starting in 2008, using an instrument called "Z-Spec" at the California Institute of Technology's (Caltech's) Submillimeter Observatory, a 33-foot (10- meter) telescope near the summit of Mauna Kea in Hawaii. Follow-up observations were made with the Combined Array for Research in Millimeter-Wave Astronomy (CARMA), an array of radio dishes in the Inyo Mountains of Southern California.The second group, led by Dariusz Lis, senior research associate in physics at Caltech and deputy director of the Caltech Submillimeter Observatory, used the Plateau de Bure Interferometer in the French Alps to find water. In 2010, Lis's team serendipitously detected water in APM 8279+5255, observing one spectral signature.Bradford's team was able to get more information about the water, including its enormous mass, because they detected several spectral signatures of the water, according to JPL.
