SEOUL, Aug. 31 (Xinhua) -- South Korea's infant mortality rate decreased by nearly half in the last 20 years to stand as the world's 16th lowest, a report showed Wednesday.South Korea had an infant mortality rate of 2.2 per 1,000 in 2009, compared with four deaths per 1,000 newborns reported in 1990, the World Health Organization (WHO) and Save the Children, an international non-governmental organization working for children's rights, said in a joint report.With a 45 percent decline in the infant mortality rate, South Korea ranked 16th lowest among WHO member countries, down from its 88th spot in 1990, according to the report. South Korea's infant mortality rate was the same as France, Estonia and Malta. Meanwhile, the Democratic People's Republic of Korea (DPRK) also showed a decline in the infant mortality rate from 23 per 1,000 in 1990 to 18.1 per 1,000 in 2009, but still remained in the lower ranks with 125th place.

SAN FRANCISCO, June 9 (Xinhua) -- Hewlett-Packard Co. (HP) on Thursday announced that its tablet computer, HP TouchPad, will go on sale in the United States on July 1.Two versions of HP TouchPad, with the option of either 16 gigabytes or 32 gigabytes of internal storage, and both only with Wi-Fi connection, will be available in the United States for 499. 99 U.S. dollars and 599.99 dollars respectively, the company said in a statement.The product will hit stores in Britain, Ireland, France and Germany a few days later and in Canada in mid-July, with availability scheduled to follow later this year in Italy, Spain, Australia, China's Hong Kong, New Zealand and Singapore.Preorders in North America and Europe will begin on June 19, HP said.HP did not release the price details when it introduced TouchPad on Feb. 9. The black device, with a 9.7-inch touch screen, runs webOS operating system, a mobile platform developed by Palm, a smartphone maker acquired by HP last April for 1.8 billion dollars.

WASHINGTON, June 8 (Xinhua) -- Hundreds of small genetic variations are associated with autism spectrum disorders, including an area of DNA that may be a key to understanding why humans are social animals, according to a multi-site collaborative study led by researchers at Yale University.To be published Thursday in the journal Neuron, the study reinforces the theory that autism, a disorder that develops in early childhood involving impairments in social interaction, language deficits and distinctive behaviors, is not caused by one or two major genetic defects, but by many small variations, each associated with a small percentage of cases.The study looked at more than 1,000 families in which there was a single child with an autism spectrum disorder, an unaffected sibling and unaffected parents. The team compared individuals with autism to their siblings to determine what types of genetic changes distinguished the affected child from the unaffected child.One of the most intriguing of these findings points to the same small section of the genome that causes Williams syndrome -- a developmental disorder marked by high sociability and an unusual aptitude for music.In autism, there is an increase in the chromosomal material, an extra copy of this region, and in Williams syndrome, there's a loss of that same material," said lead author Matthew State. "What makes this observation particularly interesting is that Williams syndrome is known for a personality type that is highly empathetic, social, and sensitive to the emotional state of others. Individuals with autism often have difficulties in the opposite direction. This suggests that there is an important key in that region to understanding the nature of the social brain."State and his team also found about 30 other regions in the genome that are very likely contributing to autism and are focused on about six of those regions that showed the strongest evidence."We're now moving on to a second phase of the study looking at an additional 1,600 families and should be able to identify multiple new regions that are strongly implicated in autism," he said.

WASHINGTON, Sept. 27 (Xinhua) -- Debris from NASA's decommissioned Upper Atmosphere Research Satellite (UARS) that crashed to Earth on Saturday fell harmlessly in a remote area of the South Pacific Ocean, NASA said on Tuesday.According to the space agency, the Joint Space Operations Center at Vandenberg Air Force Base in California has determined the satellite entered the atmosphere over the Pacific Ocean at 14.1 degrees south latitude and 170.2 west longitude at midnight EDT Saturday. The debris field is located between 300 miles and 800 miles downrange, or generally northeast of the re-entry point."This location is over a broad, remote ocean area in the Southern Hemisphere, far from any major land mass," NASA announced, adding that it is "not aware of any possible debris sightings from this geographic area."NASA scientists estimated a 1-in-3,200 chance a satellite part could hit someone on earth. Therefore, any individual's odds of being struck are about one in 21 trillion.The UARS satellite, launched in 1991 from a space shuttle, was the first multi-instrumented satellite to observe numerous chemical constituents of the atmosphere with a goal of better understanding atmospheric photochemistry and transport.

GENEVA, Sept. 26 (Xinhua) -- Two million people worldwide are estimated to die from air pollution each year, the Geneva based World Health Organization (WHO) said in its air quality report published on Monday.According to data collected by the WHO from nearly 1,100 cities across 91 countries, elevated level of fine particle pollution, which could cause heart diseases, lung cancer, asthma and acute lower reparatory infections, are common across many urban areas, with some cities registering fine particle pollution levels 15 times as much as the WHO guidelines.For both developed and developing countries, the biggest contributors to urban outdoor air pollution include motor transport, small-scale manufacturers and other industries, burning of biomass and coal for cooking and heating, as well as coal-fired power plants.Residential wood and coal burning for space heating is said to be an important contributor to air pollution, especially in rural areas during colder months, the WHO report said.
