Despite cleaner cars on the road, a University of California, Riverside study shows that higher speed limits make city air dirtier.

Triage — when first responders assess the severity of patient injuries to determine the need for treatment and what treatment to provide — is critical to saving lives at the scene of a car crash, fire or other emergency. The updated guidelines could benefit emergency responders and patients alike once the issues are addressed. The project was awarded through a cooperative effort between the National Highway Traffic Safety Administration and the National Center for Disaster Medicine and Public Health, which is administered under the Uniformed Services University.

Using advanced DNA sequence analysis, a research team led by NYU Tandon School of Engineering's Assistant Professor Elizabeth Hénaff has discovered that tiny organisms in Brooklyn's highly contaminated Gowanus Canal have developed a comprehensive collection of pollution-fighting genes.  This finding suggests the potential of a cheaper, more sustainable, and less disruptive method for cleaning contaminated waterways than the current oft-used dredging operations.
