Exposure to larger air particles linked to increased risk of asthma in children

Fri, 15 Dec 2017 10:53:10 EST ~ Researchers report statistical evidence that children exposed to airborne coarse particulate matter a mix of dust, sand and non-exhaust tailpipe emissions, such as tire rubber are more likely to develop asthma and need emergency room or hospital treatment for it than unexposed children.

Clearing the air

Thu, 14 Dec 2017 14:07:15 EST ~ A greater understanding of the dynamics of chemical reactions is leading to better models of atmospheric chemistry. Through this work, scientists are gaining insight into a key chemical able to break down some major air pollutants. Find out more...

Increased air pollution linked to bad teenage behavior

Wed, 13 Dec 2017 14:37:20 EST ~ A new study linking higher levels of air pollution to increased teenage delinquency is a reminder of the importance of clean air and the need for more foliage in urban spaces. The study suggests ambient air pollution may increase delinquent behavior among 9- to 18-year-olds in urban neighborhoods in Greater Los Angeles. The insidious effects are compounded by poor parent-child relationships and parental mental and social distress, researchers report. Find out more...

Hydraulic fracturing negatively impacts infant health, study finds

Wed, 13 Dec 2017 14:37:03 EST ~ Health risks increase for infants born to mothers living within 2 miles of a hydraulic fracturing site, according to a new study. Find out more...

After the fire, charcoal goes against the grain, with the flow

Mon, 11 Dec 2017 14:04:12 EST ~ A two-year study of property damaged by a 2011 forest fire found that charcoal behaved very differently from other forms of soil carbon as the land rebounded from the fire. The study could help researchers and land managers make better use of charcoal soil amendments called biochar. Find out more...

Exposure to air pollution just before or after conception raises risk of birth defects

Mon, 11 Dec 2017 09:07:55 EST ~ Women exposed to air pollution just prior to conception or during the first month of pregnancy face an increased risk of their children being born with birth defects, such as cleft lip or palate or abnormal hearts. Find out more...

Marine organisms can shred a plastic bag into 1.75 million pieces, study shows

Fri, 08 Dec 2017 09:55:24 EST ~ A single plastic grocery bag could be shredded by marine organisms into 1.75 million microscopic fragments, according to new research. Find out more...

The molecular structure of a forest aroma deconstructed

Thu, 07 Dec 2017 11:49:45 EST ~ The fresh, unmistakable scent of a pine forest comes from a medley of chemicals produced by its trees. Researchers have now accurately determined the chemical structure of one compound in its gas phase, a molecule called alpha-pinene. The analysis can help scientists better detect and understand how alpha-pinene reacts with other gases in the atmosphere, a process that can affect health and climate. Find out more...

Tackling China's severe air pollution problem

Thu, 07 Dec 2017 10:24:50 EST ~ More must be done to tackle air pollution in China, according to a leading climate change expert in a new study. Find out more...

Living on thin air -- microbe mystery solved

Wed, 06 Dec 2017 13:22:11 EST ~ Scientists have discovered that microbes in Antarctica have a previously unknown ability to scavenge hydrogen, carbon monoxide and carbon dioxide from the air to stay alive in the extreme conditions. The find has implications for the search for life on other planets, suggesting extraterrestrial microbes could also rely on trace atmospheric gases for survival. Find out more...
