SINGAPORE, Oct. 10 (Xinhua) -- A Singapore start-up firm has devised an innovative application to allow phone users to have access to their positioning information within buildings, where traditional global positioning system has often proved inaccurate, local daily Business Times reported on Monday.The firm YFind Positioning System feels that the application can help turn Singapore into the world's first location- intelligent city.Ting See Ho, co-founder of the firm, said the application works by first verifying the GPS coordinates to identify the building the user is in, and then collecting RSSI (received signal strength information) readings off WiFi access points within the building.The information is then sent by the phone to the central positioning server for comparison against records of the radio map of the building, which is calibrated earlier by the company.Ting said the RSSI readings continually fluctuates, making it difficult to estimate a position. This is where YFind Positioning System steps in with its patent-pending probabilistic algorithms to help accurately estimated the user's indoor positions.Once the phone application determines the location, then, it is able to map a course for a shop or other destination within the building where the user wants to go."You can think of it as creating an 'indoor GPS' environment in the buildings where satellite signals cannot be read," Ting said.He said that more than ten organizations in Singapore have approached the company to discuss deployment and partnerships and that it has begun work on three proof-of-concepts.The company's immediate goal is to make Singapore the world's first location-intelligent city before going to other cities, he said.

BEIJING, Nov. 30 (Xinhuanet) -- Heading football frequently may cause brain damage leading to subtle but serious declines in thinking and coordination skills, a new study suggested as quoted by media reports Wednesday.Researchers used an advanced MRI (Magnetic Resonance Imaging) technique to analyze changes in brain white matter of 32 adult amateur soccer players who head balls 436 times a year on average.The study found players who head football quite frequently -- with 1,000 or more a year -- showed abnormalities similar to traumatic brain injuries suffered in car accidents."This is the first study to look at the effects of heading on the brain using sophisticated diffusion tensor imaging," said Dr. Michael Lipton, a leading researcher and associate director of the Gruss Magnetic Resonance Research Center at the Albert Einstein College of Medicine in New York City."We found the real implication for players isn't from hitting headers once in a while, but repetitively, which can lead to degeneration of brain cells," he added.The researchers compared neurological images of study participants, whose average age was 31, and found those with the highest volume of headers had abnormalities in five areas of the brain, responsible for attention, memory, physical mobility and high-level visual functions.The findings come in the wake of mixed reports on the so-called "cognitive" consequences of frequently heading soccer balls at practice.Dr. Chris Koutures, a pediatrician and sports medicine specialist in Anaheim Hills, California, said the retrospective imaging study was fascinating, but needs more data to effectively determine safe header limits, especially for younger players.Dr. Lipton agreed neuropsychological damage from headers would be hard for a coach or physician to notice since cognitive problems develop gradually, and even players might not be aware of mild memory loss."We can't tell an individual today not to be heading a ball, but caution is a good thing," Lipton said. "We need more research for definitive answers and we have the advanced imaging tools to do it."

XUZHOU, Dec. 13 (Xinhua) -- Three critically injured students died in hospital in east China's Jiangsu Province early Tuesday, the government said, bringing the toll of Monday's school bus overturn to 15.The accident was the third serious one involving a school bus in China in less than a month.At least eight other children are still hospitalized, a government spokesman of Fengxian County said, without elaborating on the conditions of their injuries.A bus carrying 29 students on their way home fell into a roadside ditch when the driver tried to avoid a pedicab in the rural areas of Fengxian at 5:50 p.m. on Monday.The bus belonged to a primary school in Shouxian township. The government said the bus, designed with a maximum carrying capacity of 52 persons, was not overloaded.Also on Monday, another school bus carrying 59 students was badly hit by a truck in the city of Foshan, Guangdong Province, injuring 37 students, Guangzhou Daily reported Tuesday. Seven of the injured had been hospitalized.The accidents occurred only a day after the State Council moved to strengthen school bus safety after a deadly crash killed 19 pupils about a month ago.The nine-seat school bus illegally carrying 64 people collided head-on with a coal truck in northwestern Gansu Province on Nov. 16, killing 19 preschoolers and two adults, and injuring 43 others.Schools are few in numbers in the vast and sparsely populated rural areas of China. School bus is a relatively new thing in some rural areas as for decades children from the countryside had been trekking on rugged countryroads on foot to attend school. But rural school buses varied on quality and safety.Chinese Premier Wen Jiabao had called on government departments to "rapidly" draft safety regulations and standards for school buses while further improving the design, production and distribution of the vehicles.

BEIJING Jan. 10 (Xinhuanet) -- Scientists have found a plant in Brazil using leaves to capture the tiny worms in the soil, according to Monday's Proceedings of the National Academy of Sciences in the U.S.The plant, named Philcoxia, was found in the tropical grassland of Brazil, where the biodiversity is well conserved.As the scientists searching for the answer of why the plant grows the leaves underground, they found the 1.5 millimeters-wide leaves can trap the worms and produce a digestive enzyme to help its roots to absorb the nutrition.Although it is not the first meat-eating plant to be discovered, the finding has still "broaden up our perception about plants," according to researcher Rafael Silva Oliveira, a plant ecologist at the State University of Campinas in Brazil.It suggests that carnivorous plants "may have evolved independently more times in plants than previously thought," he added

BEIJING, Oct. 26 (Xinhua) -- The central government allocated 935 million yuan (147 million U.S. dollars) Wednesday to areas hit by rain-triggered floods, the Ministry of Civil Affairs (MCA) said.The relief funds, jointly allocated by the MCA and the Ministry of Finance, will be used for disaster survivors to relocate, rebuild houses and buy daily necessities.The funds will also be delivered to the family members of the victims, according to the ministry.The funds will go to the flood-hit provinces of Shanxi, Henan, Hubei, Sichuan, Shanxi and Guangxi Zhuang Autonomous Region.The government already allocated 132 million yuan (20.6 million U.S. dollars) to disaster hit areas immediately after the floods happened in September.Rain-triggered floods and disasters left 97 people dead, 21 missing and 1.23 million affected in September in China's 11 provincial-level regions, and a total of 1.93 million people were relocated urgently to avoid further casualties.The disasters also caused an estimated 21 billion yuan (3.29 billion U.S. dollars) in direct economic losses, according to official data.
