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 4 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced Wednesday that its Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to test.The experiment, launched in 2004, used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational body, and frame- dragging, the amount a spinning object pulls space and time with it as it rotates.GP-B determined both effects with unprecedented precision by pointing at a single star, IM Pegasi, while in a polar orbit around Earth. If gravity did not affect space and time, GP-B's gyroscopes would point in the same direction forever while in orbit. But in confirmation of Einstein's theories, the gyroscopes experienced measurable, minute changes in the direction of their spin, while Earth's gravity pulled at them.The findings are available online in the journal Physical Review Letters."Imagine the Earth as if it were immersed in honey. As the planet rotates, the honey around it would swirl, and it's the same with space and time," said Francis Everitt, GP-B principal investigator at Stanford University. "GP-B confirmed two of the most profound predictions of Einstein's universe, having far- reaching implications across astrophysics research."GP-B is one of the longest running projects in NASA history, with agency involvement starting in the fall of 1963 with initial funding to develop a relativity gyroscope experiment. Subsequent decades of development led to groundbreaking technologies to control environmental disturbances on spacecraft, such as aerodynamic drag, magnetic fields and thermal variations. The mission's star tracker and gyroscopes were the most precise ever designed and produced.GP-B completed its data collection operations and was decommissioned in December 2010."The mission results will have a long-term impact on the work of theoretical physicists," said Bill Danchi, senior astrophysicist and program scientist at NASA Headquarters in Washington. "Every future challenge to Einstein's theories of general relativity will have to seek more precise measurements than the remarkable work GP-B accomplished."

LOS ANGELES, March 5 (Xinhua) -- Law enforcement agencies are now using smart phones to track and arrest graffiti vandals in Los Angeles, a newspaper report said on Saturday.The graffiti-tracking program, spearheaded by the Tracking and Automated Graffiti Removal System, or TAGRS, allows graffiti- cleaning crews equipped with smart phones to photograph the markings and upload them to a Los Angeles Police Department (LAPD) database, the Los Angeles Times said.The photos are used to gather evidence for prosecution and restitution, the paper quoted city officials as saying.Once the graffiti suspects' identities are discovered, the information is added to the TAGRS database and may eventually uncover incidents involving the same suspects, the paper said.The LAPD launched a pilot project in 2009 in Van Nuys near Los Angeles, modeling its version on one run by the Orange County Sheriff's Department, according to the report.The program is now anchored at four LAPD stations, Van Nuys, Hollenbeck, Central and Harbor, said Mayor Antonio Villaraigosa's spokeswoman Casey Hernandez.Los Angeles spends about 10 million dollars a year cleaning up graffiti, Hernandez said.

BEIJING, Feb. 2 (Xinhua) -- From dumplings in the north and rice cakes in the south, people across China Wednesday overloaded their tables with holiday foods, cheering for the Spring Festival family reunion and praying for a better life in the coming Year of Rabbit.In a remote village in Guizhou Province, villagers were sharing millet cakes and preserved pork as sunshine dispelled cold and sleet, which have plagued China's southwest for a month."This year's Spring Festival is especially cheerful, since our dream of a new home has come true," said villager Zhang Jiuyun.Zhang's home was severely damaged in the snow and sleet disaster, but with the help of local villagers and funds from the government, Zhang built a larger house without spending much money.The Spring Festival is also an important occasion for migrant workers to enjoy family reunions after toiling for higher incomes in wealthy coastal provinces for a year."I've brought back red wine and cookies imported from Italy as gifts for my parents," said Ding Zhenghe, a Shenzhen-based factory owner who has worked his way up from a migrant worker.But Ding said, after years in the modern city, he still yearns for the the food cooked by his mother in the rural home.The Spring Festival, which falls on Thursday, also marks the start of the Year of the Rabbit. It is a time for family dinners, gift giving and fireworks.Nangkun Tashi, a villager in the earthquake-hit Yushu, northwest China's Qinghai Province, celebrated the first Lunar New Year after the disaster with traditional Tibetan food, such as mutton and butter tea.A 7.1-magnitude earthquake jolted Yushu in April 2010, killing about 2,200 people and leaving Tashi's village in ruins.Tashi's family narrowly survived the quake, and have recently moved into a new home, which was provided by the local government two months before.In Zhouqu County, Gansu Province, 990 tons of grains have been delivered to the 473 survivors, who now lived in temporary housing after a massive landslide leveled the county, leaving over 1,500 people dead in August."We are able to hold a celebration, even though we've lost everything in the landslide," said local resident Yao Shelin."We've received flour, cooking oil, and even the wok is a donation," said Yao.

BEIJING, March 21 (Xinhuanet) -- A new device is being developed by American engineers to ease pain of blood sugar testing in diabetics, according to foreign media report last week.The upcoming device is the research target of a team of engineers at Arizona State University. It is specifically designed for patients with type1diabetes and type2 diabetes, according to a report in the "Journal of Diabetes Science and Technology,"  The traditional method of testing blood sugar levels involves painful pricks on the fingers to draw blood for testing. The inconvenient and painful process may somehow leave diabetics lax in their testing. The blood sugar levels, when poorly controlled, are very likely to trigger complications including heart disease, kidney disease and retinopathy.Unlike the old testing method, the new device could help people keep track of their blood sugar levels without the need to break the skin. It draws tears to measures the blood sugar levels in the fluid and gives just an accurate reading of blood sugar levels. "This new technology might encourage patients to check their blood sugars more often, which could lead to better control of their diabetes by a simple touch to the eye." said Jeffrey T. LaBelle, developer of the device.The new testing device has drawn great interest from investors due to its promising prospects. However, it still awaits a significant amount of testing before it can hit the market.
