HOUSTON, July 25 (Xinhua) -- A shelter-in-place was ordered after a battery caught fire during a testing at NASA's Johnson Space Center Monday morning.A battery was being tested inside a containment system when it got overheated and caught fire at about 9 a.m. local time, ABC quoted the Houston Fire Department (HFD) sources as reporting.A shelter-in-place was issued for a few buildings because it's believed that one of the bi-products of the combustion could be dangerous, HFD said.The fire was put out before 11:30 a.m.A firefighter was injured when a hydrant cap blew off and struck him, according to ABC.

NEW YORK, Aug. 19 (Xinhua) -- U.S. crude oil price edged down on Friday, ending the week with a 3.65-percent loss, the fourth straight drop in the week.With absence of major macro-economic news, crude prices on Friday mainly followed the dollar's steps. As the dollar dipped to its historic low against the Japanese yen while dropping also against the euro, oil rallied for most of the trading session.But in the last trading hour, crude turned negative because the dollar bounced back from low and the U.S. stocks turned to red. The dollar index, tracking the greenback's performance against a basket of currencies, fell 0.4 percent.Crude prices fell sharply on Thursday as fears of a double-dip recession triggered sell-off of riskier assets. WTI dropped nearly 6 percent. On Friday, the markets seemed to start calming down. But for the week, it still posted a fall of 3.65 percent.Light, sweet crude for September delivery fell moderately 12 cents, or 0.15 percent to settle at 82.26 dollars a barrel on the New York Mercantile Exchange after trading from 79.17 to 83.55 dollars.But in London, Brent crude for October delivery gained 1.63 dollars, or 1.52 percent to close at 108.62 dollars a barrel. For this week, it gained 59 cents, or 0.55 percent.

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.

ROME, Sept. 27 (Xinhua) -- The 30th general assembly of the International Council for Science (ICSU) kicked off here on Tuesday to address key global challenges, featuring over 275 scientists and experts from all over the world.The goal of the four-day event, hosted for the first time in Rome by the National Research Center (CNR) as Italy's scientific member at ICSU, is to discuss how science can contribute to boosting sustainable development, fighting climate change, increasing well-being and health in the changing urban environment and tackling the side-effects of progress.At the official opening ceremony, CNR president Francesco Profumo stressed that scientific research was the key to solving all current crises."It's during times of crises that inventions, great strategies and discoveries are made," he said quoting Albert Einstein."Global cooperation is crucial in addressing society's needs. In the wake of the negative economic outlook we are witnessing research and technological transfer can turn into efficient instruments to guide countries towards a solid development giving us the tools to tackle with lucidity the great obstacles we face," observed Profumo.Appealing to both private and public institutions, Profumo thus urged to boost strategic partnerships between universities, governments and research centres."We must create a network of knowledge-sharing together with enterprises in order to multiply and better implement growth and well-being opportunities. But in order to do so concrete political decisions must be undertaken and financial resources are needed," he added.

SAN FRANCISCO, July 12 (Xinhua) -- Facebook and Time Warner announced on Tuesday that they are teaming up to launch a wide- ranging, major cross-platform partnership initiative to fight bullying.The multi-media campaign, named "Stop Bullying: Speak Up" after the original anti-bullying initiative by Time Warner's Cartoon Network, will integrate broadcast, print, online and social media to educate parents, teachers and youth about the actions that will help protect young people from the impact of bullying, the two said in a joint statement.As part of the initiative, Facebook is scheduled to launch an interactive application in the back-to-school season this fall, which will enable educators, parents, and kids to make a personal commitment to help stop bullying."We care deeply about the safety of our nation's children and are proud to be partnering with Time Warner to raise awareness of bullying," Sheryl Sandberg, Facebook's chief operating officer, said in the statement."We believe that by working together with parents and teachers, we can teach young people to speak up and stop bullying," she added.Time Warner is also planning to expand its multiplatform efforts to communicate the anti-bullying message to an broader audience.It said in October, three of its magazines -- People, Sports Illustrated and Time -- and their affiliated websites will feature editorial content that highlights the problem of bullying and innovative programs and measures being taken to combat it.In partnership with Facebook, CNN's Anderson Cooper will also host a new town hall, which is scheduled to air in October and will be dedicated to discussing bullying issues confronting kids today as well as discussions with experts to teach adults on coping with the bullying epidemic."I'm confident that through our multiplatform approach and combined resources we can inspire even more people to take action against bullying," said Jeff Bewkes, Time Warner's chairman and chief executive officer.
