WELLINGTON, Oct. 17 (Xinhua) -- Parents wanting to help their children avoid asthma and other allergies are being told to give their toys a frosty reception by sticking them in the freezer.Medical scientists in New Zealand and Taiwan have discovered that freezing children's soft toys can kill almost all house dust mites (HDMs), the microscopic bugs associated with a range of allergies, including asthma.Other effective remedies for killing HDMs, commonly found in children's soft toys, were tumble drying and washing with eucalyptus oil and detergent, the scientists from New Zealand's University of Otago and Taiwan's Changhua Christian Hospital found.HDMs were strongly associated with the development of asthma in children, and the severity of asthma was in proportion to the number of house dust mites a child was exposed to when sleeping with soft toys, said a statement from the university Monday."Children frequently sleep with their favorite toys close to their airways and this may be important for HDM-sensitized asthmatic children," said University of Otago Associate Professor Rob Siebers.The scientists tested the three different cleaning methods on 36 toys divided into three groups of 12.Freezing toys for at least 16 hours at minus 15 degrees centigrade resulted in a 95-percent reduction of HDMs, as did soaking in an emulsion of eucalyptus oil and liquid detergent for one hour before rinsing and drying.Hot tumble drying for one hour reduced mites by 89 percent, the study found."Washing and soaking with eucalyptus oil and detergent is very effective in not only reducing live mites, but also reducing house dust mite allergens, compared to freezing and tumble drying," said Siebers.Ten of the 12 toys cleaned this way showed no live mites at all.Siebers said all three methods were more effective than just washing toys, because water needed to be above 55 degrees centigrade to kill HDMs, but this usually damaged the toys."My advice for parents is to either tumble dry for one hour, or freeze the soft toy overnight, and then wash it in a cold wash to remove any allergens."Siebers said the thickness of the material used in making the toys could alter the effectiveness of the three methods.The scientists would conduct further research to determine how quickly HDMs recolonized soft toys and how often toys should be treated.The study has been published in the European journal, Paediatric Allergy and Immunology.

BEIJING, Jan. 8 (Xinhua) -- China's central authorities have highlighted travel safety as the nation on Sunday officially kicked off the world's largest holiday migration, a time in which mass numbers of passengers will be homeward bound for the traditional Chinese Spring Festival.Safe travel has emerged as a hot-button issue facing the government as passenger trips during the 40-day travel peak are expected to hit a record high of over 3 billion.Liu Tienan, vice chief of the National Development and Reform Commission, the country's top economic planner, told the press on Sunday that passenger transport during the period is not looking good as the enormous migration outweighs existing transportation capacities.?A volunteer guides passengers to their train at Chengdu Railway Station in Chengdu, capital of southwest China's Sichuan Province, Jan. 7, 2012. Starting from Jan. 8, 2012, China's transport system will undergo a 40-day travel rush, which is characterized by a hightened passenger flow around the time of the oncoming Chinese New Year.Liu warned of the likelihood of heavy snow and icy rain that could hamper travel while vowing greater efforts to avoid another travel disaster, as was seen in early 2008 when unprecedented heavy snow and freezing rain inundated the south of the country, bringing traffic to a standstill during the peak holiday season.A total of 3.16 billion passenger trips are expected during the next 40 days, up 9.1 percent from a year earlier, of which, 235 million trips will be made via the country's railways, up 6.1 percent year-on-year.Hu Yadong, vice minister of railways, said a daily average of 5.88 million people will make train trips during the period, 340,000 more than the corresponding period in 2011.At the Beijing Railway Station on Sunday, staff members checked passengers' train tickets and ID cards, as an ID-based train ticket purchasing system kicked off nationwide at the start of the new year in an effort to curb ticket scalping.

BAIKONUR, Kazakhstan, Nov. 9 (Xinhua) -- Russia's Phobos-Grunt probe and China's Yinghuo-1 satellite were launched from the Baikonur cosmodrome in Kazakhstan on a Zenit-2SB rocket at 00:16 am Moscow time Wednesday (2016 GMT Tuesday).The main aim of the Phobos-Grunt unmanned mission is to bring back the first ever soil sample from Phobos, the larger of Mars' two moons.Russia had spent about 5 billion rubles (about 161 million U.S. dollars) preparing for the three-year mission, which would include drilling Phobos' surface and returning 200 grams of soil back to Earth, according to Russian state space agency Roscosmos.The mission would also collect bacteria samples for two Russian and one U.S. biological experiments.In the meantime, China's first Mars probe Yinghuo will go into orbit around Mars and observe the planet itself.Phobos-Grunt is planned to reach Mars in 2012, then deploy its lander for Phobos in 2013 and return the soil sample back to Earth in August 2014.The Chinese probe, which would not land on Mars nor return to the Earth, is expected stay permanently in the space and communicate with the ground control directly via satellites.The Chinese probe is 75 cm long, 75 cm wide and 60 cm high. It weighs 115 kilograms and was designed for a two-year life to discover why water disappeared from Mars and shed light on other environmental changes on the planet.Victor Khartov, chief designer and director general of Lavochkin Research & Production Association, told Xinhua that the three-year mission is highly complicated."It consists of eight sub-missions: launch, travel to Mars vicinities, separation with the Chinese probe YH-1, landing on Phobos, soil collection, launch from Phobos, way back to the Earth, and final landing. Failure of any one of them could doom the entire project," he said.The launch of Phobos-Grunt and Yinghuo-1, originally scheduled for October 2009 on a Russian carrier rocket, has been postponed until 2011 due to "technical reasons" on the Russian side.
