Connie K. Ho for RedOrbit.com 13,000 premature deaths in the United Kingdom were caused by emissions from cars, planes, power plants, and trucks, according to a new study by MIT Researchers. The findings, published in this month´s issue of the journal Environmental Science and Technology, are based off of data from 2005. Steven Barrett and co-author Steve Yim found that car and truck exhaust was the leading cause of premature death. 3,300 affected people died each year, as compared...

New research from North Carolina State University shows that federal requirements governing diesel engines of new tractor trailer trucks have resulted in major cuts in emissions of particulate matter (PM) and nitrogen oxides (NOx) — pollutants that have significant human health and environmental impacts. “These requirements for new emission control technologies have increased costs for truck owners and operators, and we wanted to know whether there was any real benefit,”...

The first real-world, head-to-head comparison of "improved cookstoves" (ICs) and traditional mud stoves has found that some ICs may at times emit more of the worrisome "black carbon," or soot, particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires. The report, which raises concerns about the leading hope as a clean cooking technology in the developing world, appears in ACS' journal Environmental Science &Technology....

Scientists describe humanity's global impact as 'The Great Acceleration' and offer ominous outlook: An uncertain future on a much hotter world Time is running out to minimize the risk of setting in motion irreversible and long-term climate change and other dramatic changes to Earth's life support system, according to scientists speaking at the Planet Under Pressure conference, which began in London on Monday. The unequivocal warning was delivered on the first day of the four-day...

Where a child lives can greatly affect his or her risk for asthma. According to a new study by scientists at Columbia University, neighborhood differences in rates of childhood asthma may be explained by varying levels of air pollution from trucks and residential heating oil. Results appear online in the Journal of Exposure Science and Environmental Epidemiology. In New York City, where the study was conducted, asthma among school-age children ranges from a low of 3% to a high of 19%...

New clues as to how the Earth's remote ecosystems have been influenced by the Industrial Revolution are frozen in glaciers, according to a paper in the March issue of Nature Geoscience. "Remote regions are often perceived as being pristine and devoid of human influence," said Aron Stubbins, the study's lead author and an assistant professor at the Skidaway Institute of Oceanography. "Glaciers show us that burning fuels has an impact upon the natural functioning of ecosystems far removed...

The past decade has witnessed a significant growth in Asian air pollution, causing a great concern for air quality and climate. If government policy makers hope to contain the problem, they will need increased research and better computer models of black carbon and other aerosol pollutants, also known as atmospheric brown cloud (ABC), according to University of Iowa engineering professor Gregory Carmichael. Carmichael made the case for more research and better-informed policy makers when...

Fossil fuel signature found in Alaskan ice New clues as to how the Earth's remote ecosystems have been influenced by the industrial revolution are locked, frozen in the ice of glaciers. That is the finding of a group of scientists, including Robert Spencer of the Woods Hole Research Center. The research will be published in the March 2012 issue of Nature Geoscience. Globally, glacier ice loss is accelerating, driven in part by the deposition of carbon in the form of soot or "black...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
