(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 (PhysOrg.com) -- Agricultural Research Service (ARS) scientists are replicating the effects of climate change to see what the future holds for soybeans, wheat and the soils where they grow. http://www.physorg.com/news180298220.html Space & Earth Thu, 17 Dec 2009 19:10:01 EST news180298220 Researchers studying a period of high carbon dioxide levels and warm climate several million years ago have concluded that slow changes such as melting ice sheets amplified the initial warming caused by greenhouse gases. http://www.physorg.com/news180530639.html Space & Earth Sun, 20 Dec 2009 13:00:06 EST news180530639 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 A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground carbon-dioxide reservoirs. http://www.physorg.com/news178208871.html Physics Mon, 23 Nov 2009 14:40:02 EST news178208871 In the long term, the Earth's temperature may be 30-50% more sensitive to atmospheric carbon dioxide than has previously been estimated, reports a new study published in Nature Geoscience this week. http://www.physorg.com/news179328817.html Space & Earth Sun, 06 Dec 2009 13:34:02 EST news179328817 (PhysOrg.com) -- Researchers at Columbia University have successfully discovered a beneficial use for carbon dioxide in the conversion of organic materials, such as grass and bark, into fuel. Their findings show that if utilized on a broad scale, their technique could help significantly reduce overall carbon emissions, both from the use of carbon dioxide in biofuel production and the creation of a more energy-efficient production process. The study appears this week on the website of the Journal of Environmental Science & Technology. http://www.physorg.com/news177179481.html Space & Earth Wed, 11 Nov 2009 16:31:39 EST news177179481 Breathing carbon dioxide can trigger panic attacks, but the biological reason for this effect has not been understood. A new study by University of Iowa researchers shows that carbon dioxide increases brain acidity, which in turn activates a brain protein that plays an important role in fear and anxiety behavior. http://www.physorg.com/news178374999.html Medicine & Health Wed, 25 Nov 2009 12:37:43 EST news178374999 Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution control program will be largely offset by increases in nitrogen emissions, which the country's current policy largely overlooks. The study, which suggests that government officials adapt a more comprehensive pollution control strategy that includes a new emphasis on cutting nitrogen emissions, is scheduled for the Nov. 1 issue of ACS' Environmental Science & Technology. http://www.physorg.com/news174746733.html Space & Earth Wed, 14 Oct 2009 15:10:01 EST news174746733 (PhysOrg.com) -- Researchers studying carbon dioxide, a leading greenhouse gas and a key driver of global climate change, now have a new tool at their disposal: daily global measurements of carbon dioxide in a key part of our atmosphere. The data are courtesy of the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft. http://www.physorg.com/news180119502.html Space & Earth Tue, 15 Dec 2009 17:40:02 EST news180119502 Relatively minor increases in ocean acidity brought about by high levels of carbon dioxide have significant detrimental effects on the growth, development, and survival of hard clams, bay scallops, and Eastern oysters, according to researchers at Stony Brook University's School of Marine and Atmospheric Sciences. http://www.physorg.com/news175792205.html Space & Earth Mon, 26 Oct 2009 16:10:48 EST news175792205 (PhysOrg.com) -- Researchers at Sandia National Laboratories have built a machine that uses the sun's energy to convert carbon dioxide waste from power plants into transportation fuels such as gasoline, diesel, and jet fuel. The system could provide an alternative to carbon sequestration; instead of permanently storing CO2 underground, the CO2 could be recycled and put to use. http://www.physorg.com/news178203219.html Chemistry Mon, 23 Nov 2009 13:06:36 EST news178203219 (PhysOrg.com) -- The genetically modified cyanobacterium consumes carbon dioxide and produces the liquid fuel isobutanol by using energy from sunlight. http://www.physorg.com/news179683624.html Biology Thu, 10 Dec 2009 16:07:55 EST news179683624 Fierce competition over raw materials for new green technologies could become a thing of the past, thanks to a discovery by scientists from the University of Leeds. http://www.physorg.com/news180097093.html Space & Earth Tue, 15 Dec 2009 10:58:48 EST news180097093 (PhysOrg.com) -- Those seeking to understand and predict climate change can now use an additional tool to calculate carbon dioxide exchanges on land, according to a scientific journal article co-authored by a University of Alabama researcher and publishing this week. http://www.physorg.com/news180285034.html Space & Earth Thu, 17 Dec 2009 16:30:02 EST news180285034
