There is a common belief that species are generally moving northwards, due to climate change, with some forced out of hotter southern Europe and others suited to warm conditions now able to establish in previously cooler northern regions.

A new study from U of T Engineering’s Department of Civil & Mineral Engineering suggests that large-scale adoption of electric vehicles (EVs) could lead to significant population-level health benefits. 

A new review study in Nature Communications is the first to systematically show the harmful effects of nano- and microplastics on bees and other beneficial insects. Their function as pollinators is impaired by the plastic particles.
