Birds Exposed To Radioactive Materials Even More Bird-Brained Than Regular Birds

A study of 550 birds of 48 different species living in the exclusion zone around the site of the Chernobyl nuclear accident in Russia showed a five percent decrease in brain size directly attributable to lingering radiation. Measures taken after the reactor exploded of 1986 found traces of radioactive material in pretty much every country north of the equator. So count on future generations of humans to walk into screen doors even more frequently than we all do now. (Sidebar: the person who took the video is mean.)
