MIT researchers unravel bacteria communication pathways
MIT researchers have figured out how bacteria ensure that they respond correctly to hundreds of incoming signals from their environment. view more (2008-06-13)
Study finds no safe level for ozone
Even at very low levels, ozone-the principal ingredient in smog-increases the risk of premature death, according to a nationwide study to be published in the April edition of the journal Environmental Health Perspectives. view more (2006-02-17)
Stronger EPA leadership needed to improve water quality in Mississippi River
The U.S. Environmental Protection Agency must take a more aggressive leadership role in implementing the Clean Water Act if water quality in the Mississippi River and the northern Gulf of Mexico is to improve, says a new report from the National Research Council. view more (2007-10-17)
New bug to tackle pollution
A new, all-natural, pollutant-busting microbe has been discovered by scientists in Germany. Research published in the October 2003 issue of Microbiology, a Society for General Microbiology journal, describes a new strain of bacterium, which could be used in the near future to clean up polluted... view more (2003-10-10)
Win-win with biodegradable plastics from toxic waste
A biodegradable plastic made from toxic waste could solve pollution problems, scientists from Dublin announced today (Wednesday, 08 September 2004) at the Society for General Microbiology's 155th Meeting at Trinity College Dublin. view more (2004-08-23)
Switchable solvents make chemical manufacturing more environmentally-friendly
Researchers from Queen's University and the Georgia Institute of Technology have discovered a new environmentally-friendly way to make chemicals for pharmaceutical and other industries, such as plastics, pesticides, dyes and fragrances. view more (2005-08-26)
Persistent pollutant may promote obesity
Tributyltin, a ubiquitous pollutant that has a potent effect on gene activity, could be promoting obesity, according to an article in the December issue of BioScience. view more (2008-12-01)
How plants manage calcium may reduce effects of acid rain
A new understanding of how plants manage their internal calcium levels could lead to modifying plants to avoid damage from acid rain. The pollutant disrupts calcium balance in plants by leaching significant amounts of the mineral from leaves as well as the agricultural and forest soils the plants... view more (2007-03-12)
Scientists ramp up ability of poplar plants to disarm toxic pollutants
Scientists since the early '90s have seen the potential for cleaning up contaminated sites by growing plants able to take up nasty groundwater pollutants through their roots. Then the plants break certain kinds of pollutants into harmless byproducts that the plants either incorporate into their... view more (2007-10-16)
Adding up renewable energy
Do the overall efficiencies of renewable energy sources, such as wind, solar, and geothermal add up in terms of their complete life cycle from materials sourcing, manufacture, running, and decommissioning" Researchers in Greece have carried out a life cycle assessment to find the answer. view more (2007-08-14)
Quick Test for Polluted Environments
The "Biotool" project seeks to use bacterial marker molecules for predictions view more (2005-01-18)
Ozone levels drop when hurricanes are strengthening
Scientists are continually exploring different aspects of hurricanes to increase the understanding of how they behave. Recently, NASA-funded scientists from Florida State University looked at ozone around hurricanes and found that ozone levels drop as a hurricane is intensifying. view more (2005-06-08)
Key component of debilitating lung disease identified
For the first time, researchers have demonstrated a close correlation between the decline in a key component of the lung's antioxidant defense system and the progression of chronic obstructive pulmonary disease (COPD) in humans. view more (2008-09-12)
Acid Soils in Slovakia Tell Somber Tale
Increasing levels of nitrogen deposition associated with industry and agriculture can drive soils toward a toxic level of acidification, reducing plant growth and polluting surface waters, according to a new study published online in Nature Geoscience. view more (2008-11-18)
Asthmatic children in multi-family housing hit by indoor nitrogen dioxide
Children with asthma living in multi-family housing who are exposed to certain levels of indoor nitrogen dioxide, a poisonous pollutant byproduct of gas stoves and unvented heaters, are more likely to experience wheeze, persistent cough, shortness of breath and chest tightness. view more (2006-02-01)
Even low levels of air pollution may pose stroke risk
Short-term exposure to low levels of particulate air pollution may increase the risk of stroke or mini-stroke, according to findings that suggest current exposure standards could be insufficient to protect the public. view more (2008-06-02)
First-ever study to link increased mortality specifically to carbon dioxide emissions
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes. view more (2008-01-04)
Network of scientists is driving force in EU air pollution policy
Atmospheric protection is a big challenge for the 21st century. In teaching scientists to design outputs that become the stuff of hard policy, the impact of EUROTRAC-2 is far-reaching. Nitrogen oxides, sulphur dioxide and aerosols, major contributors to atmospheric pollution, do not respect... view more (2003-12-04)
Combatting groundwater pollution
Groundwater pollution poses a mounting threat to environmental sustainability and public health in Europe, as many countries are becoming increasingly dependent on groundwater for their drinking water supplies. As this water becomes more and more polluted, they are currently faced with two options:... view more (1998-11-16)
CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976]... view more (2007-09-20)
Fighting pollution by forecasting the future
EUREKA project E! 2634 EUROENVIRON TEAP (Tool Evaluating Air quality impact of air Pollution) has created a real-time software solution to provide pollution forecasts for industrial plants, cities and air quality authorities. It will change the way pollution is dealt with and is set to increase the... view more (2004-11-02)
Air pollution linked to cardiovascular risk indices in healthy young adults
Researchers in Taiwan have demonstrated for the first time that urban air pollution simultaneously affects key indicators of cardiovascular risk in young adults: inflammation, oxidative stress, coagulation and autonomic dysfunction. view more (2007-08-15)
Road pollution blamed for higher allergy risk in kids
New evidence blames traffic-related pollution for increasing the risk of allergy and atopic diseases among children by more than fifty percent. What's more, the closer children live to roads, the higher their risk. view more (2008-06-13)
Time spent in car drives up air pollution exposure
The daily commute may be taking more of a toll than people realize. A new study by researchers at the University of Southern California (USC) and the California Air Resources Board found that up to half of Los Angeles residents' total exposure to harmful air pollutants occurs while people are... view more (2007-10-31)
