An experiment involving a robotic tank on wheels and six trained goldfish may offer insights into animals' ability to navigate unfamiliar environments.
Researchers who detected environmental DNA, or eDNA, in two zoos say the technique could one day be used to look for endangered species in remote locations in the wild.
When brain researcher Laura Cuaya moved from Mexico to Hungary, she wanted to know if her two dogs would recognize the change in language. So she devised an experiment.

NPR's Sacha Pfeiffer speaks with a man who is concerned about CTE, and with neuroscientist Bob Stern, who explains why more cases of CTE may emerge decades after plastic helmets became commonplace.
After analyzing some 88,000 European soccer matches, scientists say games have become more predictable over time and hypothesize that salary caps could help revive the surprise.
The virus that causes COVID-19 can cause strokes, inflammation, oxygen deprivation and infection in the brain. And each of these may lead to long-term neurological problems.
The Moderna vaccine's ability to shield against infection drops sharply when tested on the omicron variant. But getting a booster pumps the protection back up again, new research suggests.
Just like humans, groups of baboons sometimes break off relations. Scientists have studied the dynamics of such breakups and say baboons tend to split up in a cooperative, egalitarian way.
Community leaders saw early in the pandemic that the city's residents of color were being hit hard by COVID-19. They worked with data analysts to show just how hard, where and why.
