BEIJING, June 14 (Xinhuanet) -- Having a pet at home during the first year of a child may halve the risk of developing allergic to them later in life, a new study suggests.The study was published in the journal Clinical & Experimental Allergy.Researchers from Henry Ford Hospital in Detroit assessed 566 boys and girls who were followed from birth until age 18. They found that boys who had dogs and teens who had cats during their first year of life had 50 percent less risk of developing pet allergies later.Lead researcher Ganesha Wegienka said: "This research provides further evidence that experiences in the first year of life are associated with health status later in life, and that early life pet exposure does not put most children at risk of being sensitised to these animals later in life."The researchers said that exposure to animals at other times in childhood didn't appear to be as significant as the first year.However, Wegienka cautioned that this study doesn't prove a cause-and-effect relationship between having a pet and avoiding allergies, just an association between those two factors."We don't want to say that everyone should go out and get a dog or cat to prevent allergies," she said."More research is needed, though we think this is a worthwhile avenue to pursue."

BEIJING, Sept. 9 (Xinhua) -- Lenovo Group, China's largest PC maker, said it aims to become the world's second-largest PC provider by the end of this year, China Daily reported Friday.The PC maker will take aggressive action to expand in the international PC market left by its competitors because of strategy adjustment, the English newspaper quoted Liu Chuanzhi, the board chairman of Lenovo, as saying.A few weeks ago, the world's biggest PC maker Hewlett-Packard Corp. said it will spin off its PC sector. Apple Inc's former CEO Steve Jobs resigned."The Chinese market is the starting point for Lenovo, but it won't be the only place Lenovo should put emphasis on. We will set up a more active strategy for expanding in overseas markets," Liu said.The PC maker has long been focusing on the global market. It purchased the PC division of the IBM Corp. a few years ago. In January, it announced a 175-million-U.S.-dollar joint venture with Japan's NEC Corp. In July, Lenovo completed its acquisition of Medion AG, a German multimedia and consumer electronics maker.

PARIS, June 14 (Xinhua) -- Solar Impulse, a Swiss solar-powered aircraft, finally arrived in Paris on Tuesday after three days' delay, ready for a debut at the biennial International Paris Air Show.The 1.6-ton solar-powered plane was expected to land in Paris on Saturday but technical problems and bad weather forced it to turn back to Brussels.The plane took its first international flight from Switzerland to Brussels on May 13 and then marked its second international flight to Paris. It has 12,000 solar cells mounted on the wings, which provide momentum for its four electric motors.Solar Impulse is the first aeroplane designed to fly day and night without requiring fuel and without producing carbon emission. The 64-meter-wingspan (as wide as an Airbus A340) can fly at extremely slow speed and has a weight equivalent to that of an average family car.Regarded as a "special guest" in the show, Solar Impulse made a historic 26-hour day and night flight without fuel in July 2010.During the Paris air show from 20 to 26 June, visitors can enjoy a close look at the innovative plane on ground every day and if weather condition permits, flying displays will take place.According to Paris Air Show organizers, 59 of the top 100 companies in the air industry worldwide will be present. More than 1,800 small and medium-sized companies will be exhibiting their products during the one-week show. Enditem
