SAN FRANCISCO, Dec. 15 (Xinhua) -- Microsoft on Thursday announced that it will automatically upgrade the Internet Explorer (IE) to the latest version to give Windows customers more protection against malicious software.According to the company's blog post, starting from Australia and Brazil next January, users of Windows XP, Vista and Windows 7 will get the IE updates if they have turned on automatic updating via Windows Update.Microsoft said the industry has been moving toward automatic updates as a norm since the biggest online threat these days is social engineering malware typically targeting outdated software like Web browsers.Automatic upgrades, also called silent updates for displaying no messages or windows during the progress, has been deployed by Google's Chrome and Mozilla's Firefox. It can ensure users have the newest versions of the browser, and therefore is seen as a big improvement to Internet security.According to the Microsoft Security Intelligence Report released in October, 99 percent of all attacks during the first half of 2011 came from unpatched but known vulnerabilities, and 90 percent of infections were attributed to vulnerability exploitation that had a security update available from the software vendor for more than a year.In the latest research data from Web analytics company StatCounter, Microsoft's IE has a strong lead with 40.63 percent of global browser market share, followed by 25.7 percent of Chrome and 25.23 percent of Firefox.

BEIJING, Jan. 23 (Xinhua) -- Nearly 200,000 local residents and tourists visited parks in Beijing on Monday as a series of celebrations were hosted to mark the first day of the Chinese lunar New Year, the city's park administration said.Festive activities kicked off at Beijing's famous parks, including the Temple of Heaven, the Summer Palace, and the Beihai Park, on Monday to welcome the Year of the Dragon, said Chen Zhiqiang, spokesman for the Beijing Municipal Administration Center of Parks.At the Temple of Heaven, 320 costumed performers on Monday staged a show presenting the royal heaven worship ceremony in the Qing Dynasty (1644-1911).In the one-hour ceremony, thousands of visitors watched as the royal parade marched toward the altar where the "emperor" held a ritual to pray for peace and good harvest in the coming year.At the Summer Palace, the ancient royal garden, a traditional fair opened to public with old-fashioned shops and stands selling items and snacks popular in the old days.The Chinese New Year, which begins on Monday this year, is an important occasion for family dinners, fireworks, and a trip to temple fairs.To cope with the increase in visitors, authorities in Beijing said they have deployed seven police choppers and 910,000 order-maintaining personnel across the city to prevent the breakout of fires and stampedes.

WASHINGTON, Dec. 12 (Xinhua) -- British scientists have discovered a new way to target cancer through manipulating a master switch responsible for cancer cell growth. The findings, published Monday in the U.S. journal Cancer Cell, reveal how cancer cells grow faster by producing their own blood vessels.Cancer cells gain the nutrients they need by producing proteins that make blood vessels grow, helping deliver oxygen and sugars to the tumor. These proteins are vascular growth factors like VEGF -- the target for the anti-cancer drug Avastin. Making these proteins requires the slotting together of different parts of genes, a process called splicing.Scientists at the University of West England and the University of Bristol discovered that mutations in one specific cancer gene can control how splicing is balanced, allowing a master switch in the cell to be turned on. This master switch of splicing makes cancer cells grow faster, and blood vessels to grow more quickly, as they alter how VEGFs are put together.In experimental models, the researchers found that by using new drugs that block this master switch they prevented blood vessel growth and stopped the growth of cancers."The research clearly demonstrates that it may be possible to block tumor growth by targeting and manipulating alternative splicing in patients, adding to the increasingly wide armory of potential anti-cancer therapies," the authors said.

SAN FRANCISCO, Nov. 4 (Xinhua) -- Google is mulling a plan to offer paid cable-TV services to consumers, a move that could flare up a new wave of competition in the traditional TV business, U.S. media reported on Friday.According to The Wall Street Journal, the Internet search giant has considered adding video and phone services to a previously announced high-speed Internet service in two U.S. cities.People briefed on the plan told the newspaper that Google has discussed distributing major TV channels from companies like Walt Disney, Time Warner and Discovery Communications as part of the video service. The discussions were still exploratory and no final decisions have been made, said the report.Google said it does not comment on rumor or speculation.Whether it is a speculation or not, the reported plan reflects possible innovation and revolution for the traditional TV experience with the growth of high-speed Internet, which may become another lucrative battlefield all the technology giants will fight for.With the growth of home and mobile broadband services, more and more video contents become available for rental, purchase and streaming on desktop computers, tablet computers and smartphones.Competitions on the video streaming market have been increasingly fierce this year, among such services as Apple's iTunes, Amazon's Prime Video, NetFlix, Hulu Plus and Vudu, which is owned by Wal-Mart.Cable companies, facing a grim picture of being kicked out in the decades to come, also fought back with their own mobile apps and online streaming services.A new Steve Jobs biography revealed that the late Apple co- founder had been working on an Apple television."It would be seamlessly synced with all of your devices and with iCloud. It will have the simplest user interface you could imagine. I finally cracked it," Jobs told biographer Walter Isaacson in the book.Some analysts said the introduction of an Apple smart TV could bring a 100-billion-U.S.-dollar revenue opportunity for the Cupertino, California-based company.Last Friday, Google-owned YouTube announced a plan to launch 100 channels on its site with original professionally produced content. A new version of Google TV was also launched with new search tools that expand results from shows on cable to web-based services like NetFlix and Amazon.

WASHINGTON, Nov. 10 (Xinhua) -- NASA's car-sized Mars rover Curiosity, which will examine one of the most intriguing areas on the Red Planet, is in final preparations for a launch from Florida 's Space Coast at 10:25 a.m. EST (15:25 GMT) on Nov. 25, the U.S. space agency announced on Thursday.Curiosity is about twice as long and more than five times as heavy as any previous Mars rover. Its 10 science instruments include two for ingesting and analyzing samples of powdered rock delivered by the rover's robotic arm. It is now sitting atop an Atlas V rocket awaiting liftoff from Cape Canaveral Air Force Station."Preparations are on track for launching at our first opportunity," said Pete Theisinger, Mars Science Laboratory project manager at NASA's Jet Propulsion Laboratory. "If weather or other factors prevent launching then, we have more opportunities through Dec. 18."Scheduled to land on the Mars in Aug. 2012, the one-ton rover will examine Gale Crater during a nearly two-year prime mission. Curiosity will land near the base of a layered mountain three miles (five kilometers) high inside the crater. The rover will investigate whether environmental conditions ever have been favorable for development of microbial life and preserved evidence of those conditions.
