JIUQUAN, Gansu, Sept. 26 (Xinhua) -- Engineers are conducting the final preparations before launching China's first space laboratory module at the end of this week at a launch center in northwest China.The unmanned Tiangong-1 module was originally scheduled to be launched into low Earth orbit between Sept. 27 and 30. However, a weather forecast showing the arrival of a cold air mass at the Jiuquan Satellite Launch Center forced the launch to be rescheduled for Sept. 29 or 30, depending on weather and other factors."This is a significant test. We've never done such a thing before," said Lu Jinrong, the launch center's chief engineer.A full ground simulation was conducted on Sunday afternoon to ensure that the module and its Long March 2F carrier rocket are prepared for the actual launch.Cui Jijun, commander-in-chief of the launch site system and director of Jiuquan Satellite Launch Center, told Xinhua that they developed a new target spacecraft for the mission and made more than 170 technical improvements to the Long March 2F, China's manned orbital carrier rocket.Engineers have also made more than 100 updates at the launch site in order to make it compatible with the Tiangong-1, Cui added.The module will conduct docking experiments after entering orbit, which is the first step in China's space station program.Cui said the launch site has an updated computer center and command monitoring system and increased ability to adapt to changes in mission conditions, as well as the resources to handle both the launch and command duties. An integrated simulation training system for space launching has also been developed for the docking mission.The mission comes just one month after the Long March 2C rocket malfunctioned and failed to send an experimental satellite into orbit. The Tiangong-1 mission was subsequently rescheduled in order to allow engineers to sort out any problems that might occur during the launch.Cui said that engineers conducted a two-month comprehensive technical check on equipment at the launch site from March to May. The safety and reliability of all the instruments have been significantly improved."[The launch site] has the full conditions to conduct the Tiangong-1 mission," said Cui.The Tiangong-1 will remain in orbit for two years. During its mission, it will dock with China's Shenzhou-8, -9 and -10 spacecrafts.Unmanned docking procedures will be an essential step toward China achieving its goal of establishing a manned space station around 2020.

GENEVA, Aug. 10 (Xinhua) -- In a bid to prevent millions of deaths and suffering every year from malnutrition, the Geneva-based World Health Organization (WHO) launched an online initiative on Wednesday.The e-Library of Evidence for Nutrition Actions (eLENA), according to WHO, offers the latest advice on tackling the three main forms of malnutrition, including undernutrition, vitamin and mineral deficiencies, as well as overweight and obesity.The recommendations by eLENA to tackle malnutrition include promoting breastfeeding and fortifying staple foods with vitamins and minerals such as iron and folic acid for wheat and maize flours.It also recommends using multiple micronutrient powders to fortify foods for children aged between six and 23 months.To prevent anaemia, daily iron and folic supplements are advised for pregnant women, and intermittent iron and folic acid supplementation is recommended for menstruating women and preschool and school-age.While overweight and obesity affect around 1.5 billion adults over age 20, and more than 40 million children aged under five across the world, underweight is the leading risk factor for many diseases in low-income countries and represents about six percent of the world medical burden, WHO statistics showed.

SAN FRANCISCO, Aug. 22 (Xinhua) -- Hewlett-Packard's tablet TouchPad has become the hottest consumer electronics device on Monday after HP launched a fire sale for the discontinued product line over the weekend."It was like a stampede and they went quick," a Best Buy employee in San Diego told technology news website Betanews, describing the line waiting to buy TouchPad. He said the discontinued tablet was sold out five minutes after the store opened.The device is also getting snatched up at a lighting speed online and increasingly difficult to find.The TouchPad is no longer listed on Bestbuy.com in the United States, which last week was reportedly sitting on 270,000 unsold TouchPads and was hoping HP would buy them back.On Amazon, TouchPad tops the world's largest online retailer's electronics sales list, beating out the electronic reader Kindle and iPod touch.Last Thursday, HP announced that it will completely shut down its webOS operations, specifically the TouchPad tablet and webOS phones.The 16 GB TouchPad currently is only 99.99 U.S. dollars, compared to the original price of 399 dollars. The 32 GB model, which used to be 485.99 dollars, is now priced at 149.99 dollars.

SAN FRANCISCO, Sept. 2 (Xinhua) -- A late-season potato blight has been detected on farms in Alaska, only the fourth time the disease appear in the U.S. state since 1995, local media reported on Friday.The disease was found this week in the fields of potato producers in cities of Delta Junction and Palmer, according to the Fairbanks Daily News-Miner, Alaska's second largest daily newspaper.Farmers in both fields are working to prevent the spread of the blight, a fungus-like disease that can kill plants in the field or cause potatoes to rot in storage, the newspaper reported.Growers have been asked to kill all affected plants within 100 feet, and plant samples from both sites will be examined to identify what type of late blight is involved.Experts said that blight can be controlled through the use of fungicides, but the cool, damp weather this summer in the areas has created an ideal environment for the disease to spread.Although Alaska's potato crop is tiny compared to other U.S. states, it has been viewed as a possible global source of seed potatoes in recent years because it is largely free of disease.A local university has explored partnerships with Chinese growers to export certified seed potatoes, noted the Fairbanks Daily News-Miner report.

SYDNEY, Sept. 5 (Xinhua) -- Australian scientists believe " brown fat," a wondrous tissue that burns energy to generate heat, could help people fight obesity, local media reported on Monday.A research team from Sydney's Garvan Institute of Medical Research (GIMR) has worked out how to grow brown fat from stem cells biopsied from adults, raising hopes that one day brown fat could be transplanted in obese people to speed up calories they burn, the Australian Associated Press (AAP) reported.Garvan endocrinologist Paul Lee, who led the research, is optimistic about targeting brown fat as an obesity intervention, commenting "it's a highly metabolically active form of fat, and very exciting that we may be able to stimulate its growth in people."People are born with supplies of brown fat around their neckline to keep them warm as infants, according to scientists at GIMR.Scientists now know that brown fat is present in most, if not all, adults mainly just behind the collarbone.Studies have found that adults with brown fat are slimmer than those without."Although this is early work, it is a proof of concept study showing that the growth of brown fat cells is possible, using precursor cells taken from adult humans, under appropriate stimulation," Lee said."Regardless of whether or not someone has lots of or little brown fat, the precursor cells are universally present. Under the appropriate growth factor and hormonal stimulation, the cells all grow and differentiate into mature brown fat cells."However, Lee warned more work was needed.Lee said even if brown fat was transplanted into obese people or drugs developed to stimulate the growth of brown fat, exercise and a healthy diet would still be crucial to aiding weight loss."So I don't think this is a solution to obesity because there are so many other factors (involved in obesity)," he said."Despite how efficient brown fat is at burning energy, we would only need a few doughnuts to diminish or negate its benefits."Lee said it would be years before tests could be carried out on brown fat transplants.In the meantime, he is expanding his study to test different ways to grow brown fat.His study, to be printed in the October issue of Endocrinology, has been published in the online edition of the journal.
