Technologists develop robust soot filter for diesel engine
In a Technology Foundation STW project, Coen van Gulijk has developed a new concept for a robust soot filter for diesel engines. As well as filter stages, the filter has an open canal so as to exclude the danger of blockage and thus fire. The new soot filter consists of series of perforated ceramic... view more (2002-09-11)

Toxicologists discover traces of diesel exhaust in the body
The Dutch toxicologists discovered that office staff, unloaders and drivers at an indoor transport company were exposed to almost the same extent as a result of ineffective ventilation of the office building. This shows how unreliable risk assessments based on occupational groups can be. To improve... view more (2000-02-21)

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)

Carnegie Mellon researchers urge regulators to rethink strategies for soot emission
Carnegie Mellon University researchers say government officials need to adopt new ways of measuring and regulating the fine particles of smoke and soot so endemic to serious health problems and the global warming crisis.   view more (2007-03-02)

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)

Cleaner diesels thanks to laser light
Measuring soot formation in a diesel engine is far from easy. Due to the turbulent environment in the combustion cylinder, no two combustion cycles are the same.   view more (2007-12-10)

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)

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)

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)

Man-made soot contributed to warming in Greenland in the early 20th century
New research shows that industrial development in North America between 1850 and 1950 greatly increased the amount of black carbon--commonly known as soot-- that fell on Greenland's glaciers and ice sheets.   view more (2007-08-10)

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)

Scientists to 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 (2007-04-19)

When a good nanoparticle goes bad
Researchers at Cornell University recently made a major breakthrough when they invented a method to test and demonstrate a long-held hypothesis that some very, very small metal particles work much better than others in various chemical processes such as converting chemical energy to electricity in... view more (2008-11-11)

Why Sloths Do Not Sleep Upside Down
Several mammal species other than ruminants and camels have a multi-chambered forestomach - kangaroos, hippos, colobus monkeys, peccaries, sloths - but they do not ruminate. As studies on the digestive physiology of these species are largely missing, it is generally assumed that their forestomach... view more (2004-04-07)

Tiny dust particles from Asian deserts common over western United States
It has been a decade since University of Washington scientists first pinpointed specific instances of air pollution, including Gobi Desert dust, traversing the Pacific Ocean and adding to the mix of atmospheric pollution already present along the West Coast of North America.   view more (2007-12-13)

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)

Background: Particulates - Ever tinier particles are coming under the researchers' microscopes
Our senses are not attuned to this danger. You can't smell them, you can't taste them and particulates are not visible to the naked eye. They are tiny, with a diameter not even a tenth of that of a hair. Yet they have a major impact.   view more (2005-03-18)

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)

Catalytic converter gets the pollution out of diesel engines
In the near future the usual summer ozone peaks exceeding the allowed threshold may be a thing of the past: the Paul Scherrer Institute (PSI) in Switzerland has developed a new type of catalytic conversion system, which filters nearly all nitrogen oxides out of diesel exhaust gases using a refined... view more (2004-09-08)

Protein that provides innate defense against HIV could lead to new treatments
By identifying a protein that restricts the release of HIV-1 virus from human cells, scientists believe they may be closer to identifying new approaches to treatment. The research is published in the advance online edition of Nature Medicine.   view more (2008-05-27)

Research points to more effective catalyst materials for petrochemical industry
Nickel oxide is a very important chemical in modern industrial processes. It is commonly used as a catalyst within the petrochemical industry in areas like the synthesis of olefin gas and the reforming reaction of methane.   view more (2006-05-12)

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)
