Coyotes are making their way into urban neighborhoods across the U.S. In the new book Coyotes Among Us, a wildlife ecologist draws from more than two decades of experience to dispel pervasive coyote myths and make the case for why humans should embrace living near coyotes.

To answer why larger brains evolved in some animals and not others, scientists looked at how different factors affect relative brain size across 1,176 bird species. They found that the amount of energy parents invested in their young played a key role in the development and evolution of larger brains among birds. The evolution of long-term parental care could also explain how the human brain grew so large.

Are humans the only animals with a mischievous sense of humor? Where did our ability to joke with one another come from? In a new study, a team of scientists report evidence of playful teasing in four great ape species: orangutans, chimpanzees, bonobos, and gorillas. These findings suggest that the cognitive building blocks of humor were likely inherited by apes and humans from our last common ancestor at least 13 million years ago.

Chickens are experiencing a surge in popularity. In the U.S. alone, there are an estimated 85 million backyard chickens, making them the third most common pet in the country. A new survey of chicken owners reveals the rising—yet still in-between—status of chickens in households.

Clinicians have long used ultrasound to image inside the body, but it may prove even more useful as a therapeutic tool. Already approved for the treatment of Parkinson’s disease and essential tremor, researchers are exploring focused ultrasound for a variety of other neurological and psychiatric conditions.
