A climate-induced decrease in water clarity could be a cause for the loon population decline in Wisconsin and more broadly across the northern United States, according to a new report from the academic journal Ecology. Researchers used satellite imagery to study water clarity in 127 lakes across northern Wisconsin from 1995 to 2021.

This spring, an unusual cicada double dose is about to invade a couple parts of the United States

The sight and sound of trillions of cicadas surfacing across much of America, a massive invasion of two separate groups called broods emerging at the same time, has scientists buzzing. For the first time in more than 200 years, two broods -- Brood XIX, known as the "Great Southern Brood," and Brood XIII, known as the "Northern Illinois Brood" -- will emerge from the ground simultaneously. While there is not extensive overlap between the two broods, some regions, especially in America's heartland
