BEIJING, Oct. 11 (Xinhuanet) -- Scientists have discovered that blind optimism is related to brain's frontal lobes which are associated with processing errors, according to a British study published Monday in the journal Nature Neuroscience.Scientists at the University College of London scanned brains of volunteers who were asked to estimate their personal likelihood of involving in negative events, like a divorce or cancer,  before and after given the average probability of these events occurring.They found that the volunteers who estimated lower probability (or the more optimistic ones) than the given one raised their estimates a little bit later while those estimated higher probability altered their estimates much more.Through the brain scanner, scientists saw there was less activity in the volunteers' frontal regions when the information given was worse than expected while more activity when the information was better than expected. It suggested that the more optimistic people neglected the negative predictions."The more optimistic we are, the less likely we are to be influenced by negative information about the future," said Dr. Tali Sharot, lead author of the study. He added being optimistic clearly had some benefits, "but it can also mean that we are less likely to take precautionary action, such as practising safe sex or saving for retirement. So why don't we learn from cautionary information?"

WASHINGTON, Dec. 2 (Xinhua) -- The U.S. Justice Department Friday approved Google's 400 million dollar acquisition of Admeld, a company that provides an online advertising platform for publishers.The Justice Department concluded that it was "not likely to substantially lessen competition in the sale of display advertising."Google operates the largest Internet search engine in the world and one of the largest display advertising platforms. It had revenues of about 29 billion dollars in 2010, most of which came from ads revenue.Admeld, with annual revenue of 30 million dollars, offers technology services to Internet publishers that help them boost revenue by optimizing ads display from hundreds of sources.Google is expected to grab 9.3 percent of online display advertising spending in the U.S. this year, up from 8.6 percent last year, making it the No. 3 provider, according to the digital intelligence company Emarketer.The No. 1 position will be taken by Facebook with its share increased to 16 percent up from 12 percent a year ago, while Yahoo! will slip slightly to 13 percent, said Emarketer.

BEIJING, Oct. 28 (Xinhuanet) -- Taking aspirin everyday may lower the risk of developing colon cancer for people with the cancer-causing genes, researchers found.The finding was published on Friday in the British medical journal "Lancet".The researchers followed 508 patients with Lynch syndrome, an inherited disorder which increases the risk of developing colon and other cancers.These patients were divided into two groups: members in one group took 600 mg aspirins everyday; another group took only the dummy pills.After 4 years, 10 colon cancer cases were reported among 258 patients who took daily aspirins for at least two years, comparing with 23 cases among 250 patients on dummy pills."This is good news for a very specific population," said Asad Umar, a cancer prevention expert at the U.S. National Cancer Institute.However, the finding doesn't apply to the general public, suggested the lead author of the study John Burn, a geneticist at Newcastle University in England.Only those who are at risk of such diseases should consider taking aspirin regularly, such as people having a family history of colon cancer, he added.

BEIJING, Dec. 26 (Xinhua) -- China has launched a one-year inter-agency national campaign aiming to return most street children home, the Ministry of Civil Affairs (MCA) said Monday.The MCA will lead the campaign, which is joined by the ministries of education, public security, financial, health, human resources and social security, and housing and urban-rural development, an MCA statement said."We will try our best to identify most street children in cities and send them home by the end of 2012," the statement said.Minister Li Liguo of Civil Affairs said, ministries concerned should strengthen communication and coordination, and speed up the revision of regulations on the relief of city beggars and vagrants.The MCA also urged provincial governments to set up special offices coordinating the campaign. Several provinces, such as Hebei and Yunnan, have been working on this, the statement said.Police will step up their efforts to identify and rescue street children who wander near railway stations, major tourist sites, business areas and subway stops, while civil affairs departments will assist investigation and provide shelter for homeless children, the statement said.Urban communities and neighborhoods are asked by the ministry to report homeless children to local police. Police and civil affairs departments will cooperate to ascertain the whereabouts of their parents or guardians.In home places of street children, education departments are urged to send them to schools or vocational schools, and those from needy families will have their tuition reduced or waived.Health departments are required to offer street children easy access to medical facilities in emergency cases. Hospitals listed in the campaign will treat sick street children free of charge.
