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)
A bubbling ball of gas
The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart up - and behind the whole thing are the magnetic fields, the engines of it all. view more (2009-11-12)
Researchers discover links between city walkability and air pollution exposure
A new study compares neighborhoods' walkability (degree of ease for walking) with local levels of air pollution and finds that some neighborhoods might be good for walking, but have poor air quality. view more (2009-11-03)
Air pollutants from abroad a growing concern, says new report
Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council. view more (2009-09-30)
Ozone layer depletion levelling off
By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale - and the findings look promising. view more (2009-09-22)
University of Toronto study shows climate change will lead to less ultraviolet radiation over northern high latitudes
Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. view more (2009-09-16)
Houseplants cut indoor ozone
Ozone, the main component of air pollution, or smog, is a highly reactive, colorless gas formed when oxygen reacts with other chemicals. view more (2009-09-09)
NOAA study shows nitrous oxide now top ozone-depleting emission
Nitrous oxide has now become the largest ozone-depleting substance emitted through human activities, and is expected to remain the largest throughout the 21st century, NOAA scientists say in a new study. view more (2009-08-28)
Scientists uncover solar cycle, stratosphere and ocean connections
Subtle connections between the 11-year solar cycle, the stratosphere, and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research appearing this week in the journal Science. view more (2009-08-28)
Small fluctuations in solar activity, large influence on the climate
Our sun does not radiate evenly. The best known example of radiation fluctuations is the famous 11-year cycle of sun spots. Nobody denies its influence on the natural climate variability, but climate models have, to-date, not been able to satisfactorily reconstruct its impact on climate activity. view more (2009-08-28)
Connections among solar cycle, stratosphere and ocean discovered
Subtle connections between the 11-year-solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research results appearing this week in the journal Science. view more (2009-08-28)
This idea doesn't stink: New tech cuts industrial odors, pollutants
A North Carolina State University researcher has devised a new technology that really does not stink. In fact, it could be the key to eliminating foul odors and air pollutants emitted by industrial chicken rendering facilities and - ultimately - large-scale swine feedlots. view more (2009-08-27)
The greenhouse gas that saved the world
When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing. But fortunately for the creation of life, water was kept liquid on our young planet. view more (2009-08-18)
Research breakthrough will lead to more accurate weather forecasts
More accurate global weather forecasts and a better understanding of climate change are in prospect thanks to a breakthrough by engineers at Queen's University Belfast's Institute of Electronics, Communications and Information Technology (ECIT). view more (2009-08-07)
Even healthy lungs labor at acceptable ozone levels
Ozone exposure, even at levels deemed safe by current clean air standards, can have a significant and negative effect on lung function, according to researchers at the University of California Davis. view more (2009-07-24)
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)
Ozone, nitrogen change the way rising CO2 affects Earth's water
Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways. view more (2009-07-10)
Ozone depletes oil seed rape productivity
High ozone conditions cause a 30% decrease in yield and an increase in the concentration of a group of toxic compounds within oilseed rape plants. view more (2009-06-29)
Beyond CO2: Study reveals growing importance of HFCs in climate warming
Some of the substances that are helping to avert the destruction of the ozone layer could increasingly contribute to climate warming. view more (2009-06-23)
Pitt Researchers Zero In on Ozone With Fluorescent Solution That Detects Harmful Molecule in the Air and Body
Researchers at the University of Pittsburgh have developed a fluorescent substance that glows bright green when exposed to even minute amounts of ozone in the air and in biological samples such as human lung cells. view more (2009-06-23)
