A new U of T study finds that diesel trains may expose passengers to elevated levels of certain pollutants, especially if they are sitting directly behind the locomotive.

A new Duke University study has found high levels of selenium in fish in three North Carolina lakes receiving power plants’ coal ash waste.

“Across the board, we’re seeing elevated selenium levels in fish from lakes affected by coal combustion residual effluents,” said Jessica Brandt, a doctoral student in environmental health at Duke’s Nicholas School of the Environment, who led the study.

York University biologist and bee expert, Professor Amro Zayed, continues to produce and publish original research of global importance. This time, he has contributed a news and views article in Nature (November 2016) that puts into context the work of an Australian researcher who discovered how natural selection allows an invader bee population to overcome the genetic odds stacked against it. The study, led by Professor Rosalyn Gloag of the University of Sydney, New South Wales, examined the invasion of Asian honeybees over an eight-year time frame.

When developing oil and gas well pads, the vegetation and soil are removed to level the areas for drilling and operations. The new assessment approach, called the disturbance automated reference toolset, or DART, is used to examine recovery patterns after well pads are plugged and abandoned to help resource managers make informed decisions for future well pad development.

Latino children who live in areas with higher levels of air pollution have a heightened risk of developing Type 2 diabetes, according to a new USC-led study.

Scientists tracked children’s health and respective levels of residential air pollution for about 3.5 years before associating chronic unhealthy air exposure to a breakdown in beta cells, special pancreatic cells that secrete insulin and maintain the appropriate sugar level in the bloodstream.
