UCI scientists discover ozone-boosting chemical reaction
Burning of fossil fuels pumps chemicals into the air that react on surfaces such as buildings and roads to create photochemical smog-forming chlorine atoms, UC Irvine scientists report in a new study. view more (2009-07-21)
Heat dangers forgotten in the battle against air pollution
UCL scientists warn that amidst all the concerns over air pollution, the more basic health message of 'staying cool when the weather is hot' may be being forgotten. view more (2005-10-12)
Researchers at the University Jaume I put environmentally-friendly refrigerants to the test
Keeping food cool in the fridge or switching on the air conditioning at the office can be costly for the environment. The gases that have been used up till now for refrigeration (mainly the so-called HCFCs, such as R22) contain high proportions of chlorine, one of the elements responsible for the depletion of atmospheric ozone. Manufacturing new... view more... (2004-06-28)
Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight. view more (2008-08-25)
Laser treatment restores art
FIRING laser beams at priceless paintings might seem the height of folly, putting the painting`s delicate pigments at risk. So while conservators have for decades used ultraviolet lasers to clean up grubby sculptures, they have always fought shy of using them on soiled paintings. But now a study has shown you can fire away with impunity. Lasers... view more... (2002-09-25)
Super deep rock formation and upper mantle move in concert
European Highlight from Geophysical Research Letters (GRL) In a finding that contradicts conventional wisdom, results from a new technique to survey the super-deep upper mantle of southern Africa show that underground volcanic rock shifted with the lithospheric plates in the area. Previously, researchers thought that the motion of the two objects... view more... (2002-03-06)
Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today. view more (2007-12-11)
Yes, Virginia, some snowflakes can look the same!
Snowflakes are one of the most recognizable and endearing symbols of winter. Their intricate shapes have been the inspiration for Christmas ornaments, jewelry and U.S. postage stamps. They are the subject of song, school projects and even scientific investigation, including a possible impact on global warming. view more (2006-12-13)
Stressed seaweed contributes to cloudy coastal skies, study suggests
Scientists at The University of Manchester have helped to identify that the presence of large amounts of seaweed in coastal areas can influence the climate. view more (2008-05-07)
Just breathe: Ozone forecaster unveiled at University of Houston, available via Web
People with asthma or other respiratory problems can breathe a sigh of relief thanks to University of Houston professors who have recently unveiled a forecasting system that provides air quality data on ozone conditions. view more (2006-08-22)
Computer-designed molecule to clean up fluorocarbons?
The chemical bond between carbon and fluorine is one of the strongest in nature, and has been both a blessing and a curse in the complex history of fluorocarbons. Now, in a powerful demonstration of the relatively new field of "computational chemistry". view more (2007-03-05)
raGraphene and gallium arsenide: two perfect partners find each other
It is the marriage of two top candidates for the electronics of the future, both excentric and extremely interesting: Graphene, one of the partners, is an extremely thin fellow and besides, very young. view more (2009-09-17)
Mailman School of Public Health researchers analyze air quality and weather changes by 2050
In a first of its kind study, a research team based at Columbia's Mailman School of Public Health found that changes in urban sprawl and climate that are projected to occur in the New York City metropolitan area by the 2050s could significantly affect air quality and health in the region. view more (2007-05-15)
Water theory is watertight, researchers say
There may be tiny bubbles in the wine, but not at the interface between water and a waxy coating on glass, a new study shows. view more (2007-01-18)
Perfecting a solar cell by adding imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost. Researchers have found a surprising way to give the nanotubes the properties they need: add defects. view more (2008-06-17)
Scripps research scientists find cause of cartilage degeneration in osteoarthritis
The scientists describe their work in this week's Early Edition of the Proceedings of the National Academy of Sciences. In the study, the team shows how the loss of the protein HMGB2, found in the surface layer of joint cartilage, leads to the progressive deterioration of the cartilage that is the hallmark of osteoarthritis. view more (2009-01-13)
Sometimes dry soils yield more clouds
Symposium of the American Meteorological Society in Wageningen (The Netherlands) Cloud formation does not always follow beaten tracks. The formation of low clouds during nice weather conditions will normally take place above moist soils. Under specific atmospheric conditions, which can occur in Europe, drier soils yield more clouds, according to a... view more... (2002-07-12)
Tiny bubbles clean oil from water
Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. view more (2009-11-16)
Chemistry & Industry - 1 July Issue
NEWS Diseases linked to UV exposure (page 4) The potentially devastating effects of a depleted ozone layer are highlighted by two recent reports detailing the link between ultraviolet exposure and disease in both humans and animals. One shows that the incidence of melanoma can be influenced by geographic location. Fallopian tube journey mimicked... view more... (2002-06-26)
Gene That Controls Ozone Resistance of Plants Could Lead to Drought-Resistant Crops
Biologists at the University of California, San Diego, working with collaborators at the University of Helsinki in Finland and two other European institutions, have elucidated the mechanism of a plant gene that controls the amount of atmospheric ozone entering a plant's leaves. view more (2008-02-28)
