Bing Eats Away at Google and Yahoo


Bing Eats Away at Google and Yahoo

It appears that the evolution introduced by  with the move from Live Search to Bing is paying off. The Redmond company introduced Bing in a move designed to grab market share from Google and Yahoo, and according to the latest statistics made public by Internet metrics companies comScore and Nielsen, Microsoft is doing just that. According to both firms Bing is on an ascendant path and has crossed the 10% milestone. While the results posted differ slightly, the general trend of Bing is positive, with the search/decision engine convincing more and more users to leverage it for their queries.

“In November 2009, Americans conducted 14.4 billion core searches, with Google Sites accounting for 65.6% search market share, up slightly from 65.4% in October. Microsoft Sites grabbed 10.3% market share, up 0.4 percentage points versus October,” revealed comScore. “Google Sites led the U.S. core search market in November with 65.6% of the searches conducted, followed by Yahoo! Sites (17.5%), and Microsoft Sites (10.3%). Ask Network captured 3.8% of the search market, followed by AOL LLC with 2.8%.”

According to comScore Google all but stagnated between October and November 2009, while Yahoo managed to drop from 18.0% to 17.5%. In the same period, Bing’s share of the search engine market grew from 9.9% to 10.3%. On the US market, Google grabbed 9.5 billion searches in November, Yahoo just 2.5 billion and Bing 1.5 billion.

The Nielsen Company credits Bing with no less than 10.7% of the search engine market, just over 1 billion searches. According to the statistics provided by Nielsen, Bing jumped 1% from October, when it accounted for a share of just 9.7% of the market. Nielsen put Yahoo at 15.3% at the end of November, down from 15.4% the previous month, and Google at 65.4%, a consistent drop from 66.1% in October, which apparently went to Bing.

It takes just 15 ciggies to raise lung cancer risk

It takes just 15 ciggies to raise lung cancer risk
A new study has shown that it takes just 15 cigarettes to increase the risk of developing lung

The research team led by Peter Campbell of the Wellcome Trust Sanger Institute in Cambridge insists that the new discovery may lead to new drugs that target the specific changes to the gene that helps to trigger the disease

The study suggests that a person may develop one mutation for every 15 cigarettes smoked.

Using new DNA sequencing technology called "massively parallel sequencing," the researchers cracked the entire cell genome and found more than 23,000 mutations that the tumour cells had acquired.

The mutations were linked with exposure to the toxins found in cigarette smoke and had accumulated over the lifetime.

"The profile of mutations we observed [in the lung-cancer patient] is exactly that expected from tobacco, suggesting that the majority of the 23,000 we found are caused by the cocktail of chemicals found in cigarettes,” the Independent quoted Campbell as saying.

“On the basis of average estimates, we can say that one mutation is fixed in the genome for every 15 cigarettes smoked," he added.

Similarly, the study conducted on patient with skin cancer showed that malignant skin cells contained changes that resulted from exposure to ultraviolet light.

"With these genome sequences, we have been able to explore deep into the past of each tumour, uncovering with remarkable clarity the imprints of these environmental mutagens [mutation-causing agents] on DNA, which occurred years before the tumour became apparent," said Professor Mike Stratton at the Sanger Institute.

The study appears in journal Nature.

Painkiller weakens anti-clotting action of aspirin

People who take painkiller Celebrex and also take a low-dose aspirin tablet daily to reduce the risk of heart attack and stroke might not be Painkiller weakens anti-clotting action of aspirin getting enough protection because the former drug keeps the aspirin from doing its job effectively, according to a new study.

In laboratory studies, University of Michigan researchers found that several coxibs, the drug class to which Celebrex belongs, interfere with aspirin’s ability to discourage blood clots, if the aspirin is taken in low doses.

Celebrex, also known as celecoxib, is the only coxib currently on the market.

frequently advise daily low-dose aspirin (81 mg) for patients who have heart conditions, notably a serious form of angina known as unstable angina, or for patients who are at risk of second heart attacks.

Aspirin is well known for its ability to discourage formation of blood clots that can lead to heart attack and stroke.

In addition, arthritis patients who take Celebrex regularly are often put on low-dose aspirin because this is thought to counteract Celebrex’s own potential clot-promoting effect.

"There are many people who take low-dose aspirin, perhaps as many as half of men over 50. If they are also prescribed Celebrex for arthritis or other pain, our results suggest that the Celebrex will probably interfere with the aspirin’s action," said Dr. William L. Smith, the study’s senior author.

"The greatest risk is having people take Celebrex who are taking aspirin for cardiovascular problems that are known to be mitigated by aspirin, including patients with unstable angina or those at risk for a second heart attack," he said.

In unstable angina, small clots form in arteries and interfere with blood flow.

Previous studies of healthy subjects found no ill effect on blood clotting when Celebrex was combined with aspirin at higher doses, specifically a daily "regular" aspirin tablet (324 mg), Smith notes.

So it may be that a higher aspirin dose, or spreading out the time between taking low-dose aspirin and Celebrex, will allow aspirin to be effective.

Aspirin’s undesirable effects on the gastrointestinal tract at higher doses when taken long-term would have to be taken into account.

While the effect seen in the study needs to be replicated in studies of low-dose aspirin and Celebrex in people, perhaps in older patients, who have conditions such as rheumatoid arthritis said Smith.

If the effect holds true in people, it will be important to determine if a balance in dose and/or dose regimens can be found so that aspirin and Celebrex can both be effective.

The results appear online in the Proceedings of the National Academy of Sciences.

93% deprived of sleep, 11% fall asleep at work: Study

BANGALORE: Ninety three percent Indians are sleep deprived and get less than the eight hours of mandatory sleep required for good health while 11 percent actually fall asleep at work, says a latest survey.

Eleven percent Indians took leave from work because of lack of sleep, according to the survey commissioned by Philips Electronics India Limited.

The survey conducted by Nielsen company in November 2009, covered 5,600 respondents in the 35-65 age group across 25 cities in urban India with a population of five lakh plus.

Fifty eight percent of the respondents felt that their work was impacted due to lack of adequate sleep with 11 percent falling asleep at work.

74 percent woke up anywhere between one to three times during their sleep. Reasons for waking up were need to answer call of nature (90 percent), stress at work (15 percent) and noise outside the home (10 percent).

Sixty two per cent of those surveyed displayed high risk of Obstructive Sleep Apnea (OSA), a condition characterised by repeated cessation of breathing during sleep and which can potentially lead to heart disease and worsen heart failure.
