BEIJING, Oct. 26 (Xinhuanet) -- The question, why the first documented supernova was super-sized and grew so fast, has puzzled astronomers for centuries. Now it is solved by US researchers.The supernova, an exploded star, was observed in 185 A.D. and documented as a mysterious "guest star" by Chinese astronomers. It was visible for eight months.Scientists later found the supernova, 8,000 light years away, was a bigger-than-expected supernova remnant. BBC reported that if the infrared light it emits could be seen by human eyes, it would appear to be as large as the full Moon in the sky.Through observations in space telescopes, researchers of a latest study revealed that the explosion took place in a cavity in space, which allowed the star's remains to travel out much faster and farther. The study was published online in the Astrophysical Journal Monday.The supernova was "two to three times bigger than we would expect for a supernova that was witnessed exploding nearly 2,000 years ago. Now, we've been able to finally pinpoint the cause," stated Brian Williams, lead author of the study and an astronomer at North Carolina State University in Raleigh.

This reinforces the argument that Canada would benefit environmentally and economically from a post 2012 international climate arrangement that systematically reduced emissions from all emitters - including Canada - over time," the report says.It recommends cooperation between governments, scientists and businesses to find ways to mitigate climate change and adapt to it.Canada's Minister of the Environment Peter Kent said the government has a plan to deal with global warming issues, which will be announced next month."Our government has a plan, a very good plan, to meet our target of reducing greenhouse gases by 17 percent from 2005 base levels, by 2020," Kent told Canada's House of Commons Thursday afternoon."We are moving forward to reduce greenhouse gases and, at the same time, we are investing in programs to help Canadians adapt to climate change," Kent said."Today's report merely echoes what our government has long recognized; that is, the importance of adaptation to climate change," he added.Earlier this week, several hundred people protested the government's policy of exploiting the oil sands deposits in western Canada.Environmentalists have criticized the Canadian government for not working hard enough to reduce CO2 emissions. Last year, a coalition of global warming activists gave Canada the "Fossil of the Year" award for failing to implement the Copenhagen Accord.

COPENHAGEN, Nov.23 (Xinhua) -- Denmark's new tax on fatty foods is having little impact on consumer habits, an opinion poll showed Wednesday.Only seven percent of those polled said they had changed their shopping habits since the tax was imposed Oct.1, said FDB Analyse, which conducted the poll for Danish news agency Ritzau.The world's first fat tax affects products containing more than 2.3 percent saturated fat, meaning a kilo of saturated fat costs 16 Danish kroner (2.87 U.S. dollars).As a result, butter, cream, cheese, meat, cooking oil and processed foods like pizza and biscuits are among thousands of products that have become dearer in recent weeks.However, two out of three respondents to the poll said price rises are too low to make them alter their dietary habits, an opinion shared by some in the food retail sector."Price rises per product vary from a few oere to 2 kroner (0.36 U.S. dollar)," said Mogens Werge, Director of Consumer Policy at Coop, a supermarket chain which accounts for 40 percent trade in basic daily goods in Denmark."No Danes will change their dietary habits just because the cost of a packet of cookies rises by 35 oere," he told DR News, Denmark's public broadcaster.The Danish Agriculture and Food Council, an industry association, says the fat tax costs a Danish family with two children an additional 1,000 kroner (180 dollars), per year.Reacting to the poll, the Social Democratic Party (SDP), which leads Denmark's coalition center-left government, said the fat tax must be given more time to take effect."There are several parameters to measure the tax, one of which is purely economic, where you have to consider a longer time period," SDP consumer affairs spokesperson Mette Reissmann, told DR News."Also, I never thought we would suddenly become a nation that rejects fatty foods. It takes a long time to change consumer behavior," she added.The government's Commission on Prevention, tasked with finding ways to improve the nation's health, also said it is too early to evaluate the fat tax's impact. It believes the tax discourages purchase of unhealthy foods, and will help raise average Danish life expectancy by one week.For their part, two-thirds of poll respondents suggested the government would do better by removing value added tax (VAT) on healthy foods like fresh fruit and vegetables, and instead raise it on food products containing fat and sugar.Denmark already imposes 25 percent VAT on most consumer goods and food products.

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

WASHINGTON, Dec. 1 (Xinhua) -- U.S. President Barack Obama announced Thursday that his administration is committing an addition 50 million U.S. dollars in funding for domestic HIV/AIDS treatment and care.Obama also set a new target of helping six million people in countries hardest hit by the HIV virus get access to life-saving antiretroviral drugs by the end of 2013, increasing the original U. S. goal by two million."We can beat this disease,"' Obama declared at a World AIDS Day event in Washington. Former Presidents George W. Bush and Bill Clinton also participated via satellite.Citing the success of the President's Emergency Plan for AIDS Relief program in providing antiretroviral treatment to people living with HIV/AIDS around the world, Obama admitted that new infections are still not going down in the United States."The rate of new infections may be going down elsewhere, but it 's not going down here in America,'' he said. "There are communities in this country being devastated still by this disease. When new infections among young, black, gay men increase by nearly 50 percent in three years, we need to do more to show them that their lives matter.''Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, also told Xinhua recently that in the United States, the AIDS epidemic has plateaued, but it is still at "unacceptably high" level.About 1.2 million Americans are living with HIV and only 28 percent of them have the infection under control, the U.S. Centers for Disease Control and Prevention reported this week."The fight is not over," Obama declared, but "the federal government can't do this alone." He called on state governments, pharmaceutical companies, and private foundations, to do their part to help Americans get access to all the life-saving treatments.Obama also appealed to global partners to step up their efforts to end AIDS, some 30 years after the epidemic first surfaced. "So on this World AIDS Day, here's my message to everyone out there. To the global community -- join us," he said.
