Frogs have maintained a surprising diversity of light-sensing proteins over evolutionary time, according to a new study led by a Penn State researcher.

A group of scientists has released the first comprehensive list of birds that haven’t been documented in more than a decade, with the help of Macaulay Library at the Cornell Lab of Ornithology.

Soaring birds — like osprey, eagles, falcons, even vultures — can stay aloft in the air seemingly forever, rarely flapping their wings. 

In a study with potential implications for the oceans and human health, scientists reported elevated mercury levels in dolphins in the U.S. Southeast, with the greatest levels found in dolphins in Florida’s St. Joseph and Choctawhatchee Bays.

Sweaty cows may not sound like the most exciting company, but in a warming world, researchers can’t get enough of them.

Gray whales that spend their summers feeding in the shallow waters off the Pacific Northwest coast have undergone a significant decline in body length since around the year 2000, a new Oregon State University study found.

Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis by scientists at the University of Illinois Urbana-Champaign.
