Firefighters face increased risk for certain cancers
University of Cincinnati (UC) environmental health researchers have determined that firefighters are significantly more likely to develop four different types of cancer than workers in other fields.   view more (2006-11-10)

Elderly have higher risk for cardiovascular, respiratory disease
New data from a four-year study of 11.5 million Medicare enrollees show that short-term exposure to fine particle air pollution from such sources as motor vehicle exhaust and power plant emissions significantly increases the risk for cardiovascular and respiratory disease among people over 65 years... view more (2006-03-08)

Reducing air pollution could increase rice harvests in India
New research from the University of California indicates that reductions of human-generated air pollution could create unexpected agricultural benefits in one of the world's poorest regions. These new findings will be published online the week of Dec. 4 in the journal Proceedings of the National... view more (2006-12-05)

Researchers show how air pollution can cause heart disease
New York University School of Medicine researchers provide some of the most compelling evidence yet that long-term exposure to air pollution-even at levels within federal standards-causes heart disease.   view more (2005-12-21)

Transported Black Carbon a Significant Player in Pacific Ocean Climate
Soot and other particulate pollution from Asian sources make up more than 75 percent of black carbon transported at high altitudes, according to a Scripps Institution of Oceanography, UC San Diego-led study.   view more (2007-03-15)

Unlocking the frozen secrets of comet Wild 2
Eleven months ago, NASA's Stardust mission touched down in the Utah desert with the first solid comet samples ever retrieved from space. Since then, nearly 200 scientists from around the globe have studied the minuscule grains, looking for clues to the physical and chemical history of our solar... view more (2006-12-20)

People with diabetes more sensitive to cardiovascular effects from air pollution
People with diabetes may be at higher risk for cardiovascular problems when air pollution levels are higher, according to a new study of Boston-area residents. The ability of the blood vessels to control blood flow was impaired in adults with diabetes on days with elevated levels of particles from... view more (2005-05-31)

Harvard Six Cities Study Follow Up: Reducing Soot Particles Is Associated with Longer Lives
An eight-year follow up to the landmark Harvard Six Cities Study has found an association between people living longer and cities reducing the amount of fine particulate matter, or soot, in their air.   view more (2006-03-16)

Asthma linked to soot from diesel trucks in Bronx
Soot particles spewing from the exhaust of diesel trucks constitute a major contributor to the alarmingly high rates of asthma symptoms among school-aged children in the South Bronx.   view more (2006-10-17)

MIT Researchers work toward spark-free, fuel-efficient engines
In an advance that could help curb global demand for oil, MIT researchers have demonstrated how ordinary spark-ignition automobile engines can, under certain driving conditions, move into a spark-free operating mode that is more fuel-efficient and just as clean.   view more (2007-07-24)

NIST laser-based method cleans up grubby nanotubes
Before carbon nanotubes can fulfill their promise as ultrastrong fibers, electrical wires in molecular devices, or hydrogen storage components for fuel cells, better methods are needed for purifying raw nanotube materials.   view more (2006-12-26)

Dust clouds in cosmic cycle
It has been a mystery for astronomers how certain dying stars have their colossal quantities of material blown out into the universe and shrink into objects called "white dwarves".   view more (2007-04-05)

Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet.   view more (2007-06-01)

NASA probes the sources of the world's tiny pollutants
Pinpointing pollutant sources is an important part of the ongoing battle to improve air quality and to understand its impact on climate. Scientists using NASA data recently tracked the path and distribution of aerosols — tiny particles suspended in the air — to link their region of... view more (2007-01-31)

Ceramic microreactors developed for on-site hydrogen production
Scientists at the University of Illinois at Urbana-Champaign have designed and built ceramic microreactors for the on-site reforming of hydrocarbon fuels, such as propane, into hydrogen for use in fuel cells and other portable power sources.   view more (2006-09-20)

Soot from wood stoves in developing world impacts global warming more than expected
New measurements of soot produced by traditional cook stoves used in developing countries suggest that these stoves emit more harmful smoke particles and could have a much greater impact on global climate change than previously thought.   view more (2006-10-25)

Scientists track impact of Asian dust and pollution on clouds, climate change
Scientists using one of the nation's newest and most capable research aircraft are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America.   view more (2007-04-20)

M. D. Anderson teaches the art of aromatherapy to soothe and heal
A bubble bath that improves memory. A kitchen cleaner that wards off nausea and energizes. A scented handkerchief that calms a patient entering the MRI. The benefits of aromatherapy are real. Below, learn the uses, healing properties and how-tos of using aromatherapy to heal and de-stress from The... view more (2006-08-28)

Laboratory scientists study soot in megacity pollution
A team of Los Alamos scientists recently returned from a month-long data-gathering trip to Mexico City as part of an international, multi-agency environmental science collaboration.   view more (2006-05-09)

Dirty snow may warm Arctic as much as greenhouse gases
The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism - dirty snow - can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases.   view more (2007-06-07)

Mapping the Milky Way
A new map of the centre of our own galaxy, The Milky Way, is the biggest, most detailed, and most sensitive yet made. The map shows giant streamers and huge clouds of interstellar gas where stars are being born 26,000 light years from Earth - shedding new light on the exotic structures in this... view more (2000-12-19)

Miniature lab ice spikes may hold clues to warming impacts on glaciers
Tiny lab versions of 12-foot tall snow spikes that form naturally on some high mountain glaciers may someday help scientists mitigate the effects of global warming in the Andes, according to a University of Colorado at Boulder professor.   view more (2007-03-06)

Invisible gases form most organic haze in urban, rural areas
A new study involving the University of Colorado at Boulder shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world.   view more (2007-07-10)

£2.3 million invested in the air that we breathe
A new institute opens today (27 January 2004) which will refine the art and science of predicting air quality. Its work will give advance warning of when air will become seriously polluted, helping people whose health may be affected.   view more (2004-01-23)
