Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen. view more (2006-08-24)
Forests damaged by Katrina may contribute to global warming
Researchers led by biologist Jeffrey Chambers of Tulane University have determined that the losses inflicted by Hurricane Katrina on Gulf Coast forest trees are enough to cancel out a year's worth of new tree biomass (trunks, branches and foliage) growth in other parts of the country. view more (2007-11-16)
Saturn's rings have own atmosphere
Data from the NASA/ESA/ASI Cassini spacecraft indicate that Saturn's majestic ring system has its own atmosphere-separate from that of the planet itself. view more (2005-08-18)
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)
Water, water everywhere -- on an extrasolar planet
Scientists report the first conclusive discovery of the presence of water vapour in the atmosphere of a planet beyond our Solar System. view more (2007-07-12)
ESA to search for life, but not as we know it
This week, astrobiologists are discussing what ESA`s Huygens spaceprobe might discover when it parachutes to the surface of Saturn`s mysterious moon, Titan, in 2005. Titan possesses a rich atmosphere of organic molecules, which Huygens will analyse. Recently some scientists have begun to think that, by redefining life, in broader terms, what we... view more...

LSU scientist finds evidence of 'rain-making' bacteria
Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere. view more (2008-02-29)
Swedish solar telescope bursts dream barrier
The first pictures from the new Swedish solar telescope on La Palma, Canary Islands, are presented in an article in the prestigious science journal Nature from November 14. The images of the sun are the most detailed ever seen. One of the most sensational discoveries is a previously unknown detailed sunspot structure. The impact of this discovery... view more...

European satellites provide new insight into ozone-depleting chemical species
Using data from the MIPAS and GOME-2 satellite instruments, scientists have for the first time detected important bromine species in the atmosphere. view more (2009-02-26)
Scientists enhance Mother Nature's carbon handling mechanism
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage. view more (2007-11-07)
A plum assignment
Plums: they're sweet, juicy, and packed with beneficial antioxidants and dietary fiber. Although there are many varieties available to consumers, there are two main types of the small, purple fruit: Japanese plums and European plums. view more (2008-09-30)
Airborne dust causes ripple effect on climate far away
When a small pebble drops into a serene pool of water, it causes a ripple in the water in every direction, even disturbing distant still waters. view more (2007-01-30)
Good breeding increases shelf life
The lettuce cut and packaged for food service and salad mixes is an increasingly important component of the produce industry. Lettuce is highly perishable, and the cutting required in processing further shortens its shelf life. view more (2008-07-21)
Carbon atmosphere discovered on neutron star
Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object. view more (2009-11-05)
Rising carbon dioxide levels increase risks to satellites
Climate change is widely attributed to the build-up of greenhouse gases, such as carbon dioxide, in the Earth's atmosphere. However, scientists from the School of Engineering Sciences at the University of Southampton have shown that the impact of carbon dioxide is being felt in space too. view more (2005-04-18)
NRL sensor to measure natural airglow in the upper atmosphere
The second of five Special Sensor Ultraviolet Limb Imager (SSULI) remote sensing instruments, developed by the Naval Research Laboratory, was launched on November 4, 2006 on board the DMSP F-17 satellite. SSULI is the first operational instrument of its kind and provides a new technique for remote sensing of the ionosphere and thermosphere from... view more... (2006-11-07)
U. of Colorado study shows massive CO2 burps from ocean to atmosphere at end of last ice age
A University of Colorado at Boulder-led research team tracing the origin of a large carbon dioxide increase in Earth's atmosphere at the end of the last ice age has detected two ancient "burps" that originated from the deepest parts of the oceans. view more (2007-05-11)
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)
Seeing the forest and the trees helps cut atmospheric carbon dioxide
Putting a price tag on carbon dioxide emitted by different land use practices could dramatically change the way that land is used - forests become increasingly valuable for storing carbon and overall carbon emissions reductions become cheaper, according to research presented today at the annual meeting of the American Association for the... view more...

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)
