BEIJING, March 15 (Xinhuanet) --After one-year effort of developing, Microsoft is going to release its newest web browser Internet Explorer 9 at 9:00 p.m. Pacific time on Monday, according to media reports.The IE 9 will be the first major Web browser to include a do-not-track tool that helps people keep their online habits from being monitored, which makes Google Inc. and Apple Inc. the only big providers of browsers that haven't yet declared their support for a do-no-track system in their products.IE 9 can work on computers running Windows Vista and Windows 7 operating systems, but not compatible with Windows XP.This final release-to-Web version of IE 9 represents the ninth release since the first platform preview of the browser appeared at the MIX 10 Web developer event, said Ryan Gavin, the senior director of Internet Explorer business and marketing. Gavin pointed out that the browser has already made its mark in Microsoft's download history."We're seeing now upwards of two percent share already on Windows 7 for IE 9, even in beta stage. It was the fastest adopted beta ever in Microsoft's history," he said.IE 9 is being launched as part of the South by Southwest event currently taking place in Austin, Texas.

BEIJING, March 10 (Xinhuanet) -- Cigarette displays in shops will be banned and tobacco companies may also be forced to make their products in plain wrappers in an attempt to stop people from smoking, announced the UK government Thursday.The prominent displays and attractive packaging of tobacco have long provided shopkeepers with stable income, keeping addicts hooked and quitters tempted.However, the government's move that will begin as early as spring next year will keep cigarettes hidden away and make it just a tad more difficult for smokers to find their fix."Nearly all adult smokers started smoking before they turned 18 and every year, over 300,000 children under 16 try smoking," said Chief Medical Officer Sally Davies."Smoking is undeniably one of the biggest and most stubborn challenges in public health. Over eight million people in England still smoke and it causes more than 80,000 deaths each year," Health Secretary Andrew Lansley said in his statement on the new law.Now, this move has drawn predictable responses from both sides of the tobacco wars, with health groups cheering and retailers grumbling.The British Medical Association said it was "very pleased" with the announcement, citing research which it said showed that a display ban would play "a key role in discouraging children from smoking and also help smokers quit."On the other hand, industry groups and independent retailers complained it would burden them with the cost of refitting their stores and reduce their already narrow profit margins.And according to media interviews, many people kept skeptical about the real impact the move would have, especially on young smokers.

LOS ANGELES, May 15 (Xinhua) -- Using a simple, minimally- invasive technique to analyze cells from the interior of the nose, U.S. researchers have detected lung cancer in its earliest stage.For the study, the researchers at the Boston University Medical Center collected nasal epithelial cells from thirty three smokers who were undergoing medically-indicated bronchoscopies for suspicion of lung cancer, according to the American Association for the Advancement of Science (AAAS) on Sunday.Of these patients, 11 were found to have benign disease and 22 had lung cancer. Brushings were taken from the right or left nostril and profiled on microarrays, a process that allows researchers to study gene expression changes.The researchers identified 170 genes that were differentially expressed between patients with and without lung cancer. They also found that genes linked to colon cancer and adenocarcinoma, as well as genes that trigger cell division and blood vessel growth, were expressed more heavily in patients with cancer. Genes involved in tumor suppression were also expressed at lower levels in these patients.Earlier studies have used gene expression differences in the bronchial airways to identify lung cancer in its early stages. The researchers relied on those results to design the current study."In this study we used the same principle as we used in our earlier studies of bronchial tissue, only this time, those methods were used to study nasal cells," said study author Christina Anderlind, MD, Instructor of Medicine. "Our hypothesis was that the upper airway epithelium of smokers with lung cancer displays a cancer-specific gene expression pattern, and that this airway nasal gene expression signature reflects the changes that occur in lung tissue."

BEIJING, May 24 (Xinhuanet) -- CT scan, a widely used heart-imaging test, is likely to result in the over treatment for patients with heart disease, according to a study published online by the Archives of Internal Medicine on Monday.CT, which produces a detailed image of the heart that reveals cholesterol buildups in the coronary arteries, is widely used in the hospital around the world."Testing might lead to more harm than good," said McEvoy, a doctor at Seoul National University Bundang Hospital in S. Korea.His team led the study, in which 2,000 healthy adults were divided into two groups. One thousand adults had CT scans and another half had standard tests, including routine checks of their blood pressure and cholesterol levels.After 18 months, the 215 people who had worrisome CT scans were advised to have additional tests and medical treatment, and some even advised to have surgery. But less than 10 percent in the group of standard test were reported to need medications.Therefore, physicians cannot easily ignore the diagnoses made by the new imaging techniques, McEvoy said, "We are left with the dilemma of what to do with the results,"According to McEvoy, doctors should focus on patients' lifestyle and traditional risk factors such as smoking and obesity.
