SAN FRANCISCO, June 17 (Xinhua) -- A new research released on Friday shows that smartphone users in the United States are consuming more data than ever, growing by 89 percent in the first quarter on a year-over-year basis.According to data from marketing company Nielsen, the amount of data the average smartphone user consumes per month is 435 Megabytes (MB) in the first quarter of 2011, compared with 230 MB in the same period last year.As for the distribution of data consumption, data usage for the top 10 percent of smartphone users is up 109 percent while the top 1 percent has grown their usage by 155 percent from 1.8 Gigabytes (GB) in the first quarter of 2010 to over 4.6 GB this year.The research said consumers with iPhones and Android smartphones consume the most data, which is driven by app-friendly operating systems like Apple's iOS and Google's Android. Windows Phone 7 users doubled their usage over the fourth quarter of 2010 and the first quarter of 2011, perhaps due to growth in the number of applications available.Meanwhile, the cost per MB for smartphones has dropped by 46 percent over the last year, from 14 cents per MB to 8 cents, said the research.According to Internet marketing research company comScore, in the first quarter of 2011, 234 million Americans ages 13 and older used mobile devices, 74,6 million of whom are smartphone users.

LOS ANGELES, July 18 (Xinhua) -- At least 70 genetic mutations may be involved in the formation of colon cancer, far more than scientists previously thought, a new study suggests.The study by researchers at University of Texas (UT) Southwestern Medical Center contradicts previous thinking that only a few mutated genes may play a role in the development of colon cancer."The ways we've been treating patients up to now is to just go after one target when we should be going after three to four different pathways simultaneously," said Dr. Jerry W. Shay, vice chairman and professor of cell biology at UT Southwestern.The new study identified 65 candidate genes and at least five passenger genes whose mutations play significant roles in cancer development. Inactivating the function of any of these tumor- suppressing genes led to a key step in cancer development called anchorage-independent growth, meaning cells piled up on top of each other rather than aligning neatly.According to previous studies, there were 151 candidate genes and that mutations in just eight to 15 of them would lead to cancer. There were 700 other genes classified as passenger genes whose mutations were incidental to cancer growth.Current cancer treatments target just one or two known cancer- driver genes. While patients may get transient tumor burden reduction, almost universally tumor growth returns."Those numbers are dead wrong," Dr. Shay said, suggesting a new approach to colon cancer treatments targeting multiple genes and pathways simultaneously.The next step is further research to classify more accurately which genes drive cancer and which are merely passengers, the researchers said.Study findings were published in the July 2011 Cancer Research (Priority Reports).

SAN FRANCISCO, Sept. 22 (Xinhua) -- Former eBay Chief Executive Officer and California governor candidate Meg Whitman on Thursday was named Hewlett-Packard's new CEO, replacing Leo Apotheker who served 11 months on the job."We are fortunate to have someone of Meg Whitman's caliber and experience step up to lead HP," said the California-based company in a statement."We are at a critical moment and we need renewed leadership to successfully implement our strategy and take advantage of the market opportunities ahead," said the troubled tech giant.It noted that the job of the HP CEO now requires additional attributes to successfully execute on the company's strategy, adding Whitman "has the right operational and communication skills and leadership abilities to deliver improved execution and financial performance.""I am honored and excited to lead HP. I believe HP matters -- it matters to Silicon Valley, California, the country and the world," said Whitman in a statement.Whitman, 55, joined the HP board in January and served as president and CEO of eBay from 1998 to 2008, when she led the company through its initial public offering and massive growth.During her last years at eBay, she is blamed for not being able to halt the sales slowdown and overpaying for the 2005 acquisition of Skype with 4.1 billion dollars. In 2009, Skype was sold by eBay at a valuation of 2.75 billion dollars.Whitman won the Republican nomination for governor of California in 2010. She lost the election to Gov. Jerry Brown after spending more than 140 million dollars of her own fortune on the campaign. EnditemHP said the appointments are effective immediately, following the decision that Apotheker stepped down as president and CEO and resigned as a director of the company.Multiple U.S. media reported on Wednesday that Apotheker was to be ousted, sending HP shares soaring on the market and in the after-hour trading.Apotheker, 58, was named HP CEO 11 months ago to replace Mark Hurd, who was ousted due to a scandal over a personal relationship with a company contractor and then became co-president of Oracle. Before HP, Apotheker had served as CEO of German software giant SAP for 10 months.On Aug. 18, Apotheker announced that HP will shut down its mobile business, spin off its core personal computer business and transfer into a cloud-based software and services provider for businesses including a 10.3 billion-dollar acquisition of British software company Autonomy.Shares of the company plunged 20 percent the following day, the worst one-day loss since Black Monday in 1987.On Sept. 30, 2010, the day before Apotheker's appointment as HP CEO, the tech giant's stock closed at 42.04 dollars. On Tuesday, the price closed at 22.47 dollars, a decrease of 46.6 percent in less than a year.On Monday, HP was reported to begin sending over 500 employees pink slips in the WebOS division, after announcing to stop making WebOS devices in August.

MOSCOW, Aug. 6 (Xinhua) -- The Arctic is getting warmer at a fast pace with the Russian Arctic sector's ice areas contracting to historically low levels, according to Russian meteorological bureau Rosgidromet.According to a Rosgidromet report cited by Itar-Tass news agency Saturday, the polar cap in the Russian sector has shrunk to the historical low registered in 2007, with no ice expected to block the Northern Seaway at least until September."Currently, Arctic navigation conditions are very favorable. By early August, navigation can be done without icebreakers almost along the entire route," said Valery Martyshchenko, head of Rosgidromet's environment pollution monitoring department.According to the Arctic and Antarctic Research Institute, the current ice cover in the Arctic Ocean is 6,860 million square kilometers, way below average.Martyshchenko said the longer period of icebreaker-free navigation would benefit the regions located in the Arctic area, allowing longer access to food and energy supplies, but the warming of the climate also posed new threats, such as melting of ice and forming of icebergs.

WASHINGTON, June 20 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Monday unveiled in a report a new strategy to meet the challenges posed by rapidly rising imports of FDA- regulated products and a complex global supply chain.The report, titled "Pathway to Global Product Safety and Quality," calls on the agency to transform the way it conducts business and to act globally in order to promote and protect the health of U.S. consumers.According to the report, the FDA will partner with its counterparts worldwide to create global coalitions of regulators focused on ensuring and improving global product safety and quality. The coalitions of regulators will develop international data information systems and networks, and increase the regular and proactive sharing of data and regulatory resources across world markets.The FDA will build in additional information gathering and analysis capabilities with an increased focus on risk analytics and information technology. It increasingly will leverage the efforts of public and private third parties and industry and allocate FDA resources based on risk."FDA regulated imports have quadrupled since 2000. The FDA and our global regulatory partners recognize this new reality and realize we must work proactively and collaboratively to address the challenges we face," FDA Commissioner Margaret Hamburg said in a statement. "The FDA must further collaborate and leverage in order to close the gap between our import levels and our regulatory resources. This report is an important step in ensuring we are able to fulfill our critical public health mission."
