Carbon monoxide linked to heart problems in elderly
Exposure to carbon monoxide, even at levels well below national limits, is associated with an increased risk of hospitalization for the elderly with heart problems, according to a study published today in Circulation: Journal of the American Heart Association. view more (2009-09-01)
MIT: 'Nanostitching' could strengthen airplane skins, more
MIT engineers are using carbon nanotubes only billionths of a meter thick to stitch together aerospace materials in work that could make airplane skins and other products some 10 times stronger at a nominal increase in cost. view more (2009-03-05)
Unexpected growth in atmospheric CO2
A team of scientists has found that atmospheric carbon dioxide (CO2) growth has increased 35 percent faster than expected since 2000. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). view more (2007-10-23)
Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning
The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil fuel but until now how this happens was at best poorly understood. view more (2005-10-10)
Magnet Made Of Pure Carbon
All known magnets contain metals and so far scientists believed that non-metallic material could not behave like a strong magnet. However, at the end of 20th century, some organic substances with strong magnetic properties were found, but they were magnetic only at very low temperatures, just above liquid helium. It seemed impossible to obtain... view more... (2001-10-24)
Carbon nanotube absorption measured in worms, cancer cells
University of Michigan researchers have discovered how to measure the absorption of multi-walled carbon nanoparticles into worms and cancer cells, a breakthrough that will revolutionize scientists' understanding of how the particles impact the living environment. view more (2006-03-29)
Nutrition and heredity are genetically linked
A challenging goal in biology is to understand how the principal cellular functions are integrated so that cells achieve viability and optimal fitness under a wide range of nutritional conditions. view more (2007-05-17)
Plants' role in global warming re-examined in ORNL Science paper
Estimates of increased plant respiration in response to higher global temperatures may be somewhat overstated as they have not taken into account plants' ability to adjust to changing conditions, according to researchers from Oak Ridge National Laboratory. view more (2006-05-02)
'Green' roofs may help put lid on global warming
"Green" roofs, those increasingly popular urban rooftops covered with plants, could help fight global warming, scientists in Michigan are reporting. view more (2009-09-24)
All the carbon counts
Cutting down forests for agriculture vents excess carbon dioxide into the air just as industrial activities and the burning of fossil fuels do. view more (2009-05-29)
Ancient Oak Trees Help Reduce Global Warming, MU Study Finds
The battle to reduce carbon emissions is at the heart of many eco-friendly efforts, and researchers from the University of Missouri have discovered that nature has been lending a hand. Researchers at the Missouri Tree Ring Laboratory in the Department of Forestry discovered that trees submerged in freshwater aquatic systems store carbon for... view more... (2008-06-30)
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)
Chemists Find Too Much Air Sticks Precious Carbon Footballs Together
Ever since researchers discovered a form of carbon consisting of a class of miniature, football-like structures known as fullerenes, they have been racing to use the unique structures in all kinds of novel ways from drug delivery to nanotechnology. However, chemists at the Universities of Warwick and Surrey have found that there could be a major... view more... (1998-12-15)
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)
Hungry microbes share out the carbon in the roots of plants
Sugars made by plants are rapidly used by microbes living in their roots, according to new research at the University of York, creating a short cut in the carbon cycle that is vital to life on earth. view more (2007-10-19)
UN body asks Lund Researchers to investigate new type of carbon sink
Trade in emission rights is intended to reduce global emissions of greenhouse gases. Countries with natural carbon sinks—areas that absorb more carbon dioxide than they give off—can ‘trade off’ that resource in return for their commitments to reduce emissions. Thus far this has largely involved forests. But now a new and... view more... (2001-11-09)
Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. view more (2009-10-15)
Studying rivers for clues to global carbon cycle
In the science world, in the media, and recently, in our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. Studying just how carbon cycles throughout the Earth is an enormous challenge, but one Northwestern University professor is doing his part by studying one important segment -- rivers. view more (2008-02-11)
How Solid Is Concrete's Carbon Footprint?
Many scientists currently think at least 5 percent of humanity's carbon footprint comes from the concrete industry, both from energy use and the carbon dioxide (CO2) byproduct from the production of cement, one of concrete's principal components. view more (2009-05-19)
Scientists should look at their own carbon footprint
Scientists studying the impact of climate change on the Arctic need to consider ways to reduce their own carbon footprints, says a researcher who regularly flies north to study the health of caribou. view more (2009-06-09)
