Deep sea algae connect ancient climate, carbon dioxide and vegetation
Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45-25 million years ago based on stable isotopes of carbon in a National Science Foundation study reported in Science Express. view more (2005-06-23)
Global warming predictions are overestimated, suggests study on black carbon
A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions. view more (2008-11-20)
Cell splits water via sunlight to produce hydrogen
Engineers at Washington University in St. Louis have developed a unique photocatalytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. view more (2007-05-03)
Scrubbing sulfur
The Department of Energy's Pacific Northwest National Laboratory has developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. view more (2009-08-18)
Carbon dioxide laser resurfacing may reduce wrinkles over long term
Carbon dioxide laser resurfacing appears to be an effective long-term treatment for facial wrinkles, according to a report in the July/August issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals. view more (2008-07-22)
Identification of carbon dioxide receptors in insects may help fight infectious disease
Mosquitoes don't mind morning breath. They use the carbon dioxide people exhale as a way to identify a potential food source. But when they bite, they can pass on a number of dangerous infectious diseases, such as malaria, yellow fever, and West Nile encephalitis. view more (2006-12-14)
Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new assessment in the September 2008 issue of BioScience. view more (2008-09-02)
Global warming of the future is projected by ancient carbon emissions
Global warming 55 million years ago suggests a high climate sensitivity to carbon dioxide, according to research led by Mark Pagani, associate professor of geology and geophysics at Yale and published in the December 8 issue of Science. view more (2006-12-08)
Food source threatened by carbon dioxide
Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today. view more (2007-12-11)
North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels. view more (2005-10-11)
Carbon dioxide and climate - the plot thickens
Using a novel technique, the researchers obtained a best estimate for carbon dioxide levels 43 million years ago of 385 parts per million (ppm), slightly higher than today's figure of 360 ppm. This result is far below earlier estimates which suggested that carbon dioxide levels were up to six times present day values. There are two ways to... view more... (1999-06-08)
UCLA researchers solve decade-old mystery
Environmentally friendly hydrogen gas fueled vehicles can dramatically reduce greenhouse gas emissions and lessen the country's dependence on sources of fossil fuel. Though several hydrogen vehicles exist on the market today, there is still much room for improvement in the way that hydrogen is stored on-board the vehicle. view more (2008-02-27)
Laser processes promise better artificial joints, arterial stents
Researchers are developing technologies that use lasers to create arterial stents and longer-lasting medical implants that could be manufactured 10 times faster and also less expensively than is now possible. view more (2009-09-16)
Titanium human “spare parts”
Heart valves bred from a patient’s own cells would be a big progress. Meanwhile, surgeons have to make do with other methods and materials: tissue grafts, modified heart valves from human or animal donors. Valves made from artificial materials have the advantage of lasting longer. But they have the unfortunate drawback to intensify the... view more... (2002-09-09)
Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences. view more (2008-10-06)
Dramatic developments at Kilauea Volcano: Scientists work to keep public safe and informed
Explosive eruptions and noxious gas emissions at Kilauea Volcano in Hawaii this week have prompted scientists to work around the clock to understand what will happen next and how to keep the public out of harm's way. view more (2008-03-28)
New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate. view more (2007-12-12)
Greenhouse gas burial
Deep coal seams that are not commercially viable for coal production could be used for permanent underground storage of carbon dioxide (CO2) generated by human activities, thus avoiding atmospheric release. view more (2007-06-26)
Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weaken
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening. view more (2007-10-23)
Beneficial effects of no-till farming depend upon future climate change
By storing carbon in their fields through no-till farming practice, farmers can help countries meet targeted reductions in atmospheric carbon dioxide and reduce the harmful effects of global warming. view more (2005-10-13)
