Study: Volkswagen's excess emissions will lead to 1,200 premature deaths in Europe
March 3, 2017 10:31 AM - Jennifer Chu via Massachusetts Institute of Technology
In September 2015, the German Volkswagen Group, the world’s largest car producer, admitted to having installed “defeat devices” in 11 million diesel cars sold worldwide between 2008 and 2015. The devices were designed to detect and adapt to laboratory tests, making the cars appear to comply with environmental standards when, in fact, they emitted pollutants called nitric oxides, or NOx, at levels that were on average four times the applicable European test-stand limit.
Brake Dust May Cause More Problems Than Blackened Wheel Covers
March 3, 2017 10:23 AM - Georgia Institute of Technology
Though tailpipe emissions could fall in the years ahead as more zero-emission vehicles hit the streets, one major source of highway air pollution shows no signs of abating: brake and tire dust.
Metals from brakes and other automotive systems are emitted into the air as fine particles, lingering over busy roadways. Now, researchers at Georgia Institute of Technology have shown how that cloud of tiny metal particles could wreak havoc on respiratory health.
Human, Cattle Viruses Detected in Some Great Lakes Tributaries

Human and bovine, or cattle, viruses were detected in a small percentage of some Great Lakes Basin streams, with human viruses more prevalent in urban streams and bovine viruses more common in streams in agricultural areas, according to a recent U.S. Geological Survey-led study.

Cigarette smoke curbs lung's self-healing
March 2, 2017 10:26 AM - Helmholtz Zentrum Munchen - German Research Center for Environmental Health
Smoke from cigarettes blocks self-healing processes in the lungs and consequently can lead to chronic obstructive pulmonary disease (COPD). Researchers at the Helmholtz Zentrum München, partner in the German Center for Lung Research (DZL), and their international colleagues have reported this in the American Journal of Respiratory and Critical Care Medicine.
Aging faces could increase security risks

Images of our faces exist in numerous important databases – driver’s license, passport, law enforcement, employment – all to accurately identify us. But can these images continue to identify us as we age?
Concurrent heat waves, air pollution exacerbate negative health effects of each
March 1, 2017 04:28 PM - University of California – Irvine
The combination of prolonged hot spells with poor air quality greatly compounds the negative effects of each and can pose a major risk to human health, according to new research from the University of California, Irvine.
“The weather factors that drive heat waves also contribute to intensified surface ozone and air pollution episodes,” said UCI professor of Earth system science Michael J. Prather, co-author of the study, published this week in Proceedings of the National Academy of Sciences. “These extreme, multiday events tend to cluster and overlap, worsening the health impacts beyond the sum of their individual effects.”
Tailored preventive oral health intervention improves dental health among elderly
March 1, 2017 09:32 AM - University of Eastern Finland
A tailored preventive oral health intervention significantly improved the cleanliness of teeth and dentures among elderly home care clients. In addition, functional ability and cognitive function were strongly associated with better oral hygiene, according to a new study from the University of Eastern Finland. The study is part of a larger intervention study, NutOrMed, and the findings were published in the Age and Aging journal.
New report assesses VA's airborne hazards and open burn pit registry

Other Means Besides a Registry Should Be Developed to Evaluate Potential Health Effects of Military Burn Pits’ Toxic Emissions on Exposed Service Members; Data From Burn Pit Registry Could Be Used for Other Purposes, Including Alerting Health Care Providers About Participants’ Concerns
More mosquito species than previously thought may transmit Zika
February 28, 2017 11:01 AM - University of Georgia
Zika virus could be transmitted by more mosquito species than those currently known, according to a new predictive model created by ecologists at the University of Georgia and the Cary Institute of Ecosystem Studies. Their findings, published today in the journal eLife, offer a list of 26 additional potential candidate species-including seven that occur in the continental United States-that the authors suggest should be the first priority for further research.
