Modelling of the Earth's atmosphere has acquired economic importance due to its use in the prediction of ozone depletion and in measuring the impact of global warming. Now, researchers, writing in the online open access journal PMC Physics B have found that the rate at which electrons lose energy to carbon monoxide is greater than that to carbon dioxide at higher levels in the atmospheres of both Mars and Venus

Pulse cooximeters have long been used to identify and measure the levels of carbon monoxide (CO) in the blood of patients or firefighters. But new research, presented at CHEST 2007, the 73rd annual international scientific assembly of the American College of Chest Physicians (ACCP), indicates that the device has another use— it can quickly, inexpensively, and noninvasively identify a person who smokes.

Despite its deadly reputation, the gas carbon monoxide (CO) could actually save lives and boost health in future as a result of leading-edge UK research.

A long-term Georgia Institute of Technology study continues to validate the effectiveness of Georgia's vehicle emissions inspection program in 13 metro Atlanta counties that are part of a federal ozone level non-attainment area.

Carbon monoxide (CO) poisoning kills over 200 people every year in the United States. Although inexpensive CO detectors have been available since 1989, their use in hotels, motels and resorts is not widespread. In fact, while every guest room in the U.S. must contain a smoke detector, there is no federal mandate for CO detectors.

Using data from the SCIAMACHY instrument aboard ESA's environmental satellite Envisat, scientists have determined that the carbon monoxide hovering over Australia during the wildfire season largely originated from South American wildfires some 13 000 kilometres away.

In a study appearing in the April 2007 issue of The FASEB Journal, scientists from Harvard University and the University of Pittsburgh have shown for the first time that the anti-inflammatory effects of carbon monoxide originate within cells' own molecular engines, mitochondria.

X-ray studies at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are pointing the way to less costly and more efficient catalysts for improving the performance of fuel cells. The studies, which will be presented by Brookhaven chemist Jose Rodriguez at the 233rd National Meeting of the American Chemical Society, show that copper can be substituted for gold in reactions that keep fuel cells functioning longer while eliminating unwanted byproducts.
