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.

BEIJING, Sept. 29 (Xinhuanet) -- Even a slightly high blood pressure is considered dangerous to largely increase the stroke risk, a new study found.The finding was published Wednesday on the online edition of U.S. medical journal Neurology.In the study, researchers found people who have pre-hypertension, whose blood pressure measured between normal and high, are 55 percent more likely to suffer a stroke compared with normal people.The study involved data from 12 previous studies on blood pressure and stroke occurrence of some 500,000 adults.About one in three U.S. adults suffer from pre-hypertension, which is defined at a systolic blood pressure between 120 and 139 or a diastolic blood pressure between 80 and 89, according to the U.S. Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure."People who do fall into the higher range of pre-hypertension should modify their lifestyle as much as possible," suggested Dr. Bruce Ovbiagele, director of the Olive View-UCLA Stroke Program and leading author of the study.Stroke is the number three cause of death, killing more than 130,000 in the U.S. a year, according to a CBS report.

WASHINGTON, Nov. 7 (Xinhua) -- U.S. researchers have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.The findings, published Monday in the online edition of the Journal of Clinical Investigation, suggest that drugs targeting the brain and central nervous system could be a novel approach to treating diabetes."The brain is the body's only organ that needs a constant supply of glucose to survive, so it makes sense that it would have some say over how much glucose is produced," said study leader Meredith Hawkins, professor of medicine and director of the Global Diabetes Initiative at Yeshiva University, in a statement. "This role for the brain was demonstrated in earlier studies in rodents, but there was considerable controversy over whether the results could be applied to humans. We hope this study helps to settle the matter."In an earlier study in rodents, researchers showed that activation of potassium channels in the brain's hypothalamus sends signals to the liver that dampen its production of glucose. Those findings, published in Nature in 2005, challenged the conventional thinking that blood sugar production by the liver (the body's glucose factory) is regulated only by the pancreas (which makes insulin to metabolize glucose). But carefully performed studies on dogs, conducted at Vanderbilt University, failed to replicate the results, suggesting the Einstein findings in rodents might not be relevant to higher mammals, including humans.The current study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before.Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain."This study confirms that the brain plays a significant role in regulating glucose production by the liver," said lead author Preeti Kishore, assistant professor of medicine. "We are now investigating whether this 'brain-to-liver' pathway is impaired in people with diabetes. If so, we may be able to restore normal glucose regulation by targeting potassium channels in the brain."

BEIJING, Oct. 21 (Xinhua) -- Vice President Xi Jinping has said China is willing to cooperate with Russia on strategic security matters, and that the two nations should work more closely on bilateral and multilateral issues.Xi made the remarks on Thursday in his meeting with Russian Security Council Secretary Nikolai Patrushev, according to a press release issued by the Chinese Foreign Ministry on Friday.China will work more closely with Russia in order to strengthen communication and coordination on regional and international issues, Xi said.Patrushev is in Beijing to co-chair the sixth round of China-Russia strategic security talks with Chinese State Councilor Dai Bingguo.Chinese Vice President Xi Jinping (R) shakes hands with Russian Security Council Secretary Nikolai Patrushev (L) in Beijing, capital of China on Oct. 20, 2011.Xi spoke highly of the contribution made by the China-Russia strategic security talks in boosting bilateral political mutual trust and strategic coordination, calling on the two sides to step up strategic coordination in a bid to better safeguard the common interests of the two nations and promote peace and stability in the world.Citing the significant and profound transition of the international situation, Xi said the two nations face opportunities as well as challenges in maintaining a strategically secure environment for their own development.On bilateral relations, Xi said China always prioritizes its relations with Russia in the country's foreign policy.
