In a follow-up analysis of the most extensive study of its kind on the long-term effects of air pollution on human health, researchers have found that people living in U.S. cities face an increased risk of dying from a heart attack as a result of long-term exposure to air pollution. This increased risk was found to be as large as that associated with being a former smoker. The new analysis is published as a study in the rapid access issue of the journal Circulation, published by the American Heart Association.
"It is clear that long-term exposure to the levels of air pollution that Americans are routinely exposed to is a significant contributor to ischemic heart disease," says George Thurston, Sc.D., Associate Professor of Environmental Medicine at NYU School of Medicine, and one of the new studys authors. "When we looked at the data, we observed that the increased risk of dying from some forms of heart disease among non-smokers living in polluted cities is roughly comparable to the increased risk caused by being a former smoker."
The new analysis is based on data collected by the American Cancer Society (ACS) on the cause of death of some 500,000 adults over a 16-year period from 1982 to 1998 and on data on pollution levels in cities nationwide. These data sets were also the basis for an earlier study, published in the Journal of the American Medical Association (JAMA) in 2002. The JAMA study showed that over many years, the danger of breathing soot-filled air in American cities significantly raised the risk of dying from lung cancer and heart disease, and the risk was comparable to the health risks of living with a smoker.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
