Humans aren’t the only species bugging out from the polar vortex, the winter weather system that’s still menacing large swaths of the United States with bone-chilling temperatures.  Be glad you’re not an Asian stinkbug, which are dying off in large numbers due to the cold, a new experiment shows.

The male hummingbird is a dedicated suitor, returning to the same place every day for up to eight months a year to trumpet his availability–for as long as eight hours at a stretch. He’ll repeat his song two times per second, hoping for a female to heed his call. Hummingbirds’ songs are distinguished by more...

When the 2014 Winter Olympics in Sochi, Russia, kick off with the opening ceremony this Friday, a leopard, a hare, and a polar bear will be among those gathering with athletes, dignitaries, and journalists. But fear not, these four-legged animals are Sochi’s official mascots. Leopards, hares, and polar bears are found in Russia, and each...

Male túngara frogs (Physalemus pustulosus) are the romantic type. Instead of roaming around looking for mates, these tiny Central and South American rain forest amphibians sit in puddles singing love songs, attracting females that flock to the aquatic crooner’s home. The frog’s calls have an unintended effect: They create ripples that draw the attention of predators lurking in...

The twin cubs, just five weeks old, have begun to glimpse their mother Giovanna and the rest of the world. (Read more about polar...

Sardis, an ancient city in modern-day Turkey, has been the site of archeological expeditions since 1910 and is still churning out new finds today. But this past July archaeologists working at the site found something particularly unusual: 2,000-year-old eggs, likely meant to bless the house as part of a purification ritual. Burying items in homes...

It’s not easy being a rodent in the U.S. Great Plains. Animals like black-tailed prairie dogs (Cynomys ludovicianus) are under constant threat of being preyed upon from land and air by predators that include hawks, eagles, and coyotes. To cope with this danger, the social animals are in constant communication, including via so-called “contagious” displays, in which...

Long before cats ruled the Internet and tamed humans to do their bidding, they had to be domesticated themselves. But the science has always been murky on when that occurred. Today’s domestic cats are believed to be the descendants of ancient Near Eastern wildcats, and the previous discovery of a wildcat buried near a human in...

New York City, home to eight million people and untold numbers of cockroaches, just got a few more of the latter. A newly seen species, Periplaneta japonica, has just been discovered in New York’s elevated High Line park. As its name implies, the cockroach is native to Japan, and this is the first time it’s been...
