WASHINGTON, Sept. 13 (Xinhua) -- The U.S. Department of Agriculture (USDA) announced Tuesday it will begin testing next year for six more kinds of E.coli bacteria in raw ground beef and tenderized steaks in order to protect the safety of the American food supply.The U.S. currently tests for one strain of E.coli O157:H7 in beef. According to the USDA, from March 5 next year, if the E. coli serogroups O26, O103, O45, O111, O121 and O145 are found in raw ground beef or its precursors, those products will be prohibited from entering commerce.Like E.coli O157:H7, these serogroups can cause severe illness and even death, and young children and the elderly are at highest risk."The Obama Administration is committed to protecting our food supply and preventing illnesses before they happen," said Agriculture Secretary Tom Vilsack in a statement. "Today's announcement does exactly that by targeting and eliminating contaminated products from the market.""Too often, we are caught reacting to a problem instead of preventing it. This new policy will help stop problems before they start," he said.About one in six Americans becomes sick from a food borne illnesses each year, an epidemic that kills about 3,000 annually and hospitalizes 128,000, according to the U.S. Centers for Disease Control and Prevention.

SAN FRANCISCO, Aug. 22 (Xinhua) -- Hewlett-Packard (HP) on Monday unveiled a new business desktop computer, days after the world's largest personal computer (PC) maker announced its plan to sell its PC business.The company said the new model, HP Compaq 8200 Elite All-in-One Business Desktop, is the industry's first all-in-one PC that integrates Intel's second-generation Core vPro technology, which can deliver up to 40 percent better performance, 15 percent faster hard drive access and reduced downtime via remote information technology management."Another industry first in our Elite desktop family demonstrates our commitment to engineering excellence and underscores our global leadership in secure, enterprise computing, " Jeff Groudan, HP's director of commercial desktop marketing, said in a statement.HP said the new computer is available now in the United States. It starts at the price of 999 U.S. dollars, and comes with a standard three-year warranty.Last Thursday the company announced that it is considering a full or partial separation of its PC business through a spin-off or other transactions, a process that HP estimates may take about 12 to 18 months.

HONG KONG, July 19 (Xinhua) -- A gene controlled by male hormone was critical for the growth of liver tumor, leading to a higher incidence of the disease in men than in women, according to the Chinese University of Hong Kong which made the results public on Tuesday.There is a significant gender bias in liver cancer incidence. In Hong Kong, men are three times more likely to develop liver cancer than women. Such phenomenon prompted researchers from the university to carry out a genomic location analysis in liver cancer cells starting from 2008.The researchers discovered, out of 17,000 human genes, that a gene called Cell Cycle-Related Kinase (CCRK) was directly controlled by androgen receptor. They further found that CCRK was critical for the induction of signaling pathway leading to abnormal liver cell growth and tumor formation.The results also reveal that 70 percent of patients with liver cancer were found to produce high levels of CCRK. More importantly, these patients were more likely to have late-stage cancers and lived shorter than those with low CCRK level.Using mouse models, the researchers found that either lowering the level or blocking the signaling pathway of CCRK in liver cancer cells could significantly reduce the tumor growth rate.The study has validated that CCRK is an important gene that has potential to cause liver cancer and the gene can be tested as a new targeted therapy in future.Vice-Chancellor of the university Joseph Sung, who is also team leader of the research project, said the results explained why men have a higher risk of liver cancer than women and helped push ahead with the development of a novel treatment of the disease.The above study results were published online in July in Journal of Clinical Investigation.

SAN FRANCISCO, June 28 (Xinhua) -- Google has launched a new site wdyl.com, a search service standing for "what do you love" and integrating a variety of Google's search products on one page.According to a report by technology blog TechCrunch, wdyl.com was quietly rolled out several days ago and the formal launch was set for Monday, but engineering issues have been holding it back until early Tuesday morning.The site can return users a single page of relevant results across a variety of Google's search services for whatever query is typed into the search box, whose search button is even a heart.For example, after typing in "pasta," several columns appear on the search results page, allowing users to see images of pasta, watch videos of pasta, or browse latest news about pasta.Other search results include pasta-related maps, books, blogs, patents, translation, popularity on the web and etc.

SAN FRANCISCO, June 14 (Xinhua) -- Apple updated its online store on Tuesday to begin offering unlocked models of iPhone 4 in the United States for the first time."The unlocked iPhone 4 requires an active micro-SIM card that you obtain from a supported GSM wireless carrier," said Apple in the product description. The iPhone requires a smaller version of the standard SIM (Subscriber Identity Module) card.Started at 649 U.S. dollars for the 16 GB version, the unlocked model is a GSM phone, which means, in the United States, the phone runs on networks of T-Mobile or AT&T, although it can only send data over T-Mobile's old EDGE network, not its 3G network and the faster HSPA+ network.Verizon and Sprint, the other two major U.S. wireless carriers, both use CDMA networks that do not use SIM cards.The iPhone 4 has been sold unlocked in other countries. For frequent international travelers, an unlocked iPhone means they just need to pop in a micro-SIM card for whichever country they are going, avoiding provider's high international fees.According to Apple, iPhone sales grew 113 percent year over year in the second quarter of its fiscal 2011, reaching a record high of 18.65 million units.
