  • Road pricing most effective in reducing vehicle emissions
    on October 5, 2017 at 6:17 pm

    For decades municipal and regional governments have used various traffic management strategies to reduce vehicle emissions, alongside advancements like cleaner fuel and greener cars. But not all traffic management strategies are created equal, says transportation experts. After reviewing more than 60 studies on the subject, scientists have concluded that road pricing -- or pay per use -- is the most effective strategy to reduce emissions and traffic. […]

  • Air pollution exposure on home-to-school routes reduces the growth of working memory
    on October 5, 2017 at 4:50 pm

    A new study has demonstrated that exposure to air pollution on the way to school can have damaging effects on children's cognitive development. The study found an association between a reduction in working memory and exposure to fine particulate matter (PM2.5) and black carbon during the walking commute to and from school. […]

  • Fish shrinking as ocean temperatures rise
    on October 4, 2017 at 5:35 pm

    One of the most economically important fish is shrinking in body weight, length and overall physical size as ocean temperatures rise, according to new research by LSU Boyd Professor R. Eugene Turner published today. The average body size of Menhaden -- a small, silver fish -- caught off the coasts from Maine to Texas -- has shrunk by about 15 percent over the past 65 years. […]

  • House sparrow decline linked to air pollution and poor diet
    on October 3, 2017 at 3:10 pm

    House sparrows are well-adapted to living in urban areas, so it is surprising their numbers have fallen significantly over the past decades. An investigation into this worrying trend finds that sparrows living in urban areas are adversely affected by pollution and poor nutrition. The study also finds the birds suffer more during the breeding season, when resources are needed to produce healthy eggs. […]
