OTTAWA, Sept. 29 (Xinhua) -- Climate change could cost Canada billions of dollars a year by the end of this decade, a government funded study group announced Thursday.The National Round Table on the Environment and the Economy said the cost of climate change for Canada could start at roughly 5 billion Canadian dollars per year in 2020 and increase to between 21 billion and 43 billion per year by 2050. Those costs would come from shoreline damage, public health problems, and disruptions to the economy.It also predicted a slight increase in deaths in major cities from heat and air pollution.The round table researchers estimated the cost of climate change is expected to be roughly 0.8 percent to 1.0 percent of GDP -- or 43 billion Canadian dollars a year -- by 2050, if the problem is allowed to worsen.But the report did not address possible benefits, such as reduced demand for hea

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. 14 (Xinhuanet) -- Facebook unveiled a new feature called "smart lists" on Tuesday, giving its users an easier way to share photos, posts and updates with smaller groups of friends.The new function, which commences on Wednesday, borrows from the success of the Circles feature of Google+, which allows users to categorize friends into groups.With the new feature, Facebook can automatically put your friends into groups, with the first four being work, school, family and city, based on the information of colleges, workplaces and geographic locations in users' profiles.The feature is optional to use, and the lists are customizable."This is really something we have been working on for four years," Facebook director of product management Blake Ross told AFP, adding "We think this is the way people will make lists going forward."In the meantime, the social networking site has also come up with "close friends" and "acquaintances" options.People can read the updates of their "close friends" more prominently in their news feed and just big news of their "acquaintances", according to Naomi Gleit, the director of product at Facebook who worked on the new feature.

PARIS, Aug. 19 (Xinhua) -- Marine scientists and representatives from the private sector and military establishments would meet at UNESCO at the end of this month to measure noise's impact on marine life, the Paris-based UN scientific branch UNESCO said Friday.The main agenda of the meeting, which is due from Aug. 30 to Sep. 1, was to discuss the program of the International Quiet Ocean Experiment (IQOE)."This decade-long project aims to fill the considerable knowledge gaps in this area, so that management of ocean noise can be more informed and effective," UNESCO said in a statement.The Quiet Ocean Experiments was initiated against the background that human activities on the high seas have increased significantly in recent decades, and resulted in impact upon many marine species relying mainly on sound to communicate.However, some sounds are suspected to alter the behavior of marine animals. For example, several whale species have raised the volume of the squeaks, clicks and moans by which they communicate with each other.The experiment is organized by the Scientific Committee on Oceanic Research (SCOR) and the Partnership for Observation of the Global Oceans (POGO), of which UNESCO's Intergovernmental Oceanographic Commission (IOC) is a member.

SAN FRANCISCO, Aug. 22 (Xinhua) -- Hewlett-Packard's tablet TouchPad has become the hottest consumer electronics device on Monday after HP launched a fire sale for the discontinued product line over the weekend."It was like a stampede and they went quick," a Best Buy employee in San Diego told technology news website Betanews, describing the line waiting to buy TouchPad. He said the discontinued tablet was sold out five minutes after the store opened.The device is also getting snatched up at a lighting speed online and increasingly difficult to find.The TouchPad is no longer listed on Bestbuy.com in the United States, which last week was reportedly sitting on 270,000 unsold TouchPads and was hoping HP would buy them back.On Amazon, TouchPad tops the world's largest online retailer's electronics sales list, beating out the electronic reader Kindle and iPod touch.Last Thursday, HP announced that it will completely shut down its webOS operations, specifically the TouchPad tablet and webOS phones.The 16 GB TouchPad currently is only 99.99 U.S. dollars, compared to the original price of 399 dollars. The 32 GB model, which used to be 485.99 dollars, is now priced at 149.99 dollars.
