http://www.physorg.com/ en-us Physorg.com internet news portal provides the latest news on science including: Physics, Nanotechnology, Life Sciences, Space Science, Earth Science, Environment, Health and Medicine. December 18, 2009, marks the tenth year since the launch of Terra, one of NASA's "flagship" Earth observing satellites. But the decade is more than just a mechanical milestone. With each additional day and year that the satellite monitors Earth, scientists achieve a lengthened record of Earth's vital signs. It's that record that helps scientists assess the health of Earth's ocean, land, and atmosphere, and determine how these systems are changing. http://www.physorg.com/news180116443.html Space & Earth Tue, 15 Dec 2009 16:50:01 EST news180116443 Improving the energy efficiency of Maryland homes heated by natural gas would generate a "hat trick" of economic and environmental benefits over the next 10 years, including more than 80,000 new jobs, savings of hundreds of dollars in average heating bills and a nine percent reduction in residential carbon emissions, concludes a new study by the University of Maryland Center for Integrative Environmental Research (CIER). http://www.physorg.com/news180096281.html Space & Earth Tue, 15 Dec 2009 10:47:06 EST news180096281 (AP) -- It isn't easy getting Italy's city dwellers out of their Fiats, off their Vespa scooters and onto bicycles to ride to work, "like here in Copenhagen," says an Italian environmental official. http://www.physorg.com/news179996898.html Space & Earth Mon, 14 Dec 2009 07:08:52 EST news179996898 The EU commission on Wednesday granted 1.5 billion euros (2.2 billion dollars) to offshore wind farms and carbon capture and storage schemes to help relaunch Europe's economy and cut greenhouse gas emissions. http://www.physorg.com/news179588792.html Technology Wed, 09 Dec 2009 14:10:03 EST news179588792 (PhysOrg.com) -- An enzyme in our blood that enables our lungs to exhale carbon dioxide could be the key to isolating carbon dioxide emissions from coal plants in order to store them safely underground. A company called Carbozyme, based in New Jersey, is developing a synthetic version of the blood enzyme that could capture carbon dioxide using one-third less energy than other methods. http://www.physorg.com/news179068055.html Chemistry Thu, 03 Dec 2009 13:08:37 EST news179068055 (AP) -- Americans' day-to-day lives won't change noticeably if President Barack Obama achieves his newly announced goal of slashing carbon dioxide pollution by one-sixth in the next decade, experts say. http://www.physorg.com/news178530693.html Space & Earth Fri, 27 Nov 2009 07:52:01 EST news178530693 Food waste contributes to excess consumption of freshwater and fossil fuels which, along with methane and carbon dioxide emissions from decomposing food, impacts global climate change. In a new paper published in the open-access, peer-reviewed journal PLoS ONE, Kevin Hall and colleagues at the National Institute of Diabetes and Digestive and Kidney Diseases calculate the energy content of nationwide food waste from the difference between the US food supply and the food eaten by the population. The latter was estimated using a validated mathematical model of human metabolism relating body weight to the amount of food eaten. http://www.physorg.com/news178349112.html Space & Earth Wed, 25 Nov 2009 05:50:05 EST news178349112 The annual rate of increase in carbon dioxide emissions from fossil fuels has more than tripled in this decade, compared to the 1990s, reports an international consortium of scientists, who paint a bleak picture of the Earth's future unless "CO2 emissions [are] drastically reduced." http://www.physorg.com/news178308523.html Space & Earth Tue, 24 Nov 2009 18:40:03 EST news178308523 Humanity would need five Earths to produce the resources needed if everyone lived as profligately as Americans, according to a report issued Tuesday. http://www.physorg.com/news178269435.html Space & Earth Tue, 24 Nov 2009 08:20:03 EST news178269435 In a provocative new study, a University of Utah scientist argues that rising carbon dioxide emissions - the major cause of global warming - cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day. http://www.physorg.com/news178178343.html Space & Earth Mon, 23 Nov 2009 05:59:57 EST news178178343 (PhysOrg.com) -- The investment in nuclear power has been growing around the world over the last few years, being viewed as a means for countries to control their energy security, avoid the price fluctuations of other energy sources, and reduce their carbon dioxide emissions, but concerns are now being raised. http://www.physorg.com/news177839133.html Physics Thu, 19 Nov 2009 09:50:06 EST news177839133 (PhysOrg.com) -- While politicians debate the best ways to cut global carbon dioxide emissions, researchers at Idaho National Laboratory's Center for Advanced Energy Studies are charging ahead on a strategy to defuse the CO2 the world already produces. They want to inject the greenhouse gas deep underground, where it would react with rocks and remain, entombed, for thousands of years. http://www.physorg.com/news177686379.html Space & Earth Tue, 17 Nov 2009 13:40:02 EST news177686379 China can become the world's top exporter of "green technology" if it carries out crucial energy and ecological reforms, leading environmental campaigners said here Saturday. http://www.physorg.com/news177394676.html Space & Earth Sat, 14 Nov 2009 04:40:02 EST news177394676 The Dutch government said Friday it wants to introduce a "green" road tax by the kilometre from 2012 aimed at cutting carbon dioxide emissions by 10 percent and halving congestion. http://www.physorg.com/news177358842.html Technology Fri, 13 Nov 2009 18:21:41 EST news177358842 The American health care sector accounts for nearly a tenth of the country's carbon dioxide emissions, according to a first-of-its-kind calculation of health care's carbon footprint. http://www.physorg.com/news177097375.html Medicine & Health Tue, 10 Nov 2009 17:43:24 EST news177097375 (AP) -- Denmark urged the European Union, the United States and other rich countries to commit to financing for a new climate change deal, saying Friday that billions of dollars are needed. http://www.physorg.com/news175525105.html Space & Earth Fri, 23 Oct 2009 14:30:01 EST news175525105 The International Air Transport Association (IATA) said Friday it would approve biofuels for commercial flights by 2010 in a bid to drastically reduce the industry's carbon footprint. http://www.physorg.com/news175525268.html Technology Fri, 23 Oct 2009 14:20:01 EST news175525268 Dr. Erez Allouche, assistant professor of civil engineering at Louisiana Tech University and associate director of the Trenchless Technology Center, is conducting innovative research on geopolymer concrete and providing ways to use a waste byproduct from coal fired power plants and help curb carbon dioxide emissions. http://www.physorg.com/news173454176.html Technology Tue, 29 Sep 2009 14:43:23 EST news173454176 (PhysOrg.com) -- Sometimes a picture really is worth a thousand words, particularly when the picture is used to illustrate science.
