BEIJING, Oct. 24 (Xinhuanet) -- The average global land temperature has increased by around one degree Cetigrade since the mid-1950s, American scientists announced last week after reviewing historical temperature records to date.According to media reports, the scientists of the Berkeley Earth project have studied more than a billion temperature records dating back to the 1800s from 15 sources around the world.And the result is in line with the estimate made by major institutions which keep official records on the global climate, including the Nasa's Goddard Institute for Space Studies in the US and the Met Office's Hadley Centre in Britain.Meanwhile, the scientists established an open database for the climate records so that skeptics on climate change can assess climage change on their own.Nevertheless, the finding of the scientists at the University of California, Berkeley did not convince climate change skeptics, according to a New York Times report.Anthony Watts, one prominent US skeptics, claimed the study's "methodology was flawed". He also noted that the finding was submitted to journal Geophysical Research Letters before being peer-reviewed.Richard Muller, a physicist and head of the project, argued that the decision to circulate the papers before publication was part a long-standing academic tradition of sanity-checking results with colleagues.He added, cited by the Guardian, "We will get much more feedback from making these papers public before publication."

BEIJING, Oct. 18 (Xinhuanet) -- Autism can likely develop when low birth weight babies are combined with other factors such as environment and genetic predisposition, new research suggests.Researchers from the University of Pennsylvania School of Nursing and School of Medicine identified 1,105 children who weighed less than 2,000 grams at birth between Oct. 1, 1984, and July 3, 1989.Sixteen years later, researchers were able to reach 623 of those children, and used a questionnaire to screen them for autism spectrum disorders.When 189 of the children turned 21 years old, 60 percent of those who screened positive for an autism spectrum disorder, and 24 percent of those who screened negative with the condition. All in all, the rate of autism spectrum disorders among the study participants with low birth weights was five times higher than the general.Autism spectrum disorder makes people have difficulty communicating, difficulty interacting in social situations, and restrictive or repetitive interests, said study co-author Jennifer Pinto-Martin, a researcher in the University.Those with mild autism spectrum disorders, "may only want to talk about one subject," Pinto-Martin said. "They're perfectly functional. They can go to college. They can hold a job." Premature babies are often born with low birth weights, though full-term babies can also have the condition. The research suggests a need not only for better prenatal care to reduce the number of premature babies, but also a need for early diagnosis and intervention for people with autism.

BEIJING, Dec. 11 (Xinhua) -- A draft regulation on school bus safety management was made public Sunday by the Legislative Affairs Office of the State Council, with the public invited to submit comments on it.The draft stipulates that local governments above the county level should take "overall responsibility" in school bus safety, and authorities of education, public security, transportation and product quality supervision should also properly perform their respective duties.The government will establish and improve a system of mandatory technical standards for the quality of vehicles used as school buses, the draft stated. Primary school students queue up to get on the school bus to go home after school in Deqing County, east China's Zhejiang Province, Nov. 21, 2011. Local government of Deqing County has invested 20 million yuan (3.14 million U.S. dollars) to order 79 school buses, which are specially designed for children with smaller seats and seat belts as well as bright yellow color to have better warning function. Among the 79 buses, 14 ones have truck-style front ends, and this appearance like a long nose can effectively reduce the impact force and better protect children's safety. Drivers of such kind of school buses are required not to exceed 60 kilometers per hour. Nearly 6,000 children from 25 primary schools have benefited from the operation of this kind of school bus in Deqing County.China issued a set of technical standards for school buses for primary school students last year, and the drafting of another standard for buses for the kindergartners is also underway.According to the draft, the government will adopt a license system for school bus operation.Vehicles that are up to school bus standards and with a unified appearance will be first in line to obtain approval from education authorities, and the draft also requires buses to register at the traffic administrative agencies before they can be used as school buses.Instead of compulsory annual safety checks, the draft would require school bus owners to renew their safety qualifications every six months.Drivers should also check the safety condition of the buses before each commute, the draft said.The draft asks schools and the school bus service providers to intensify safety management and maintenance and assign special staff on buses to look after students on board.

SAN FRANCISCO, Nov. 1 (Xinhua) -- Yahoo, which has been rumored to sell all or part of its business, announced on Tuesday that it is buying data-driven advertising network Interclick for around 270 million U.S. dollars.Interclick is a technology company providing data targeted solutions and optimization technologies."This investment underscores our focus on enhancing the performance of both our guaranteed and non-guaranteed display business across Yahoo and our partner sites and, combined with Yahoo's reach and advertising leadership, will deliver a powerful solution for marketers," said Ross Levinsohn, Yahoo's executive vice president for the Americas region.Some analysts said Interclick's technology could help Yahoo to grow its display advertising market share as Google and Facebook have gained on or surpassed the company in the area.But the acquisition also raised questions considering Yahoo's financial situation after it reported last month its revenue in the last quarter decreased by 5 percent year-over-year. The company is also in a chief executive officer (CEO) search following the firing of former CEO Carol Bartz in September and amidst reports of a possible takeover.Although in a financial struggle, Yahoo still has around 700 million unique monthly visitors and its news division is the biggest online news site with around 81.2 million unique visitors in August.Tech giants like Google and Microsoft are reported to be considering providing finance for the acquisition of Yahoo by another company or a group of companies.In a report on Monday, Bloomberg News reported that Yahoo is leaning toward selling Asian assets and redistributing the proceeds to shareholders, rather than selling itself to a group of buyers. Yahoo's shares fell more than 5 percent after the possibility was reported.
