(Credit: Shutterstock) U.S.-Cuban relations have taken an unusual turn after several U.S. diplomats, and at least one Canadian diplomat, experienced hearing damage after being targeted by a covert “sonic device” in Havana.

Chimps Understand Rock-Paper-Scissors as Well as Preschoolers

Posted on Categories Discover Magazine

Rock smashes scissors. Scissors cut paper. Paper covers rock. The rules behind the favorite game of schoolyard kids and adults deciding who takes out the trash are pretty simple. But they also represent a kind of logic problem. Four-year-olds can learn the rules, and so can chimpanzees—but the differences in how kids and apes become proficient reveal a little about how their minds work. The relationship between the three items in rock-paper-scissors is circular. There isn& ...read more

I am Dr. Erik Klemetti (you can see me up in the banner, peering out at you). I’m a professor of Geoscie ...read more

Posted on Categories Discover Magazine

Astronomers still don’t know what life might be like — or if it could exist — on planets near twice the size of our own. Would these worlds be toxic wastelands or ocean oases?(NASA/JPL-Caltech/Ames) If you look up at Earth’s night sky and find the constellation Cetus — it looks something like a sea monster — you might also notice a rather average looking star called Tau Ceti. It’s slightly smaller than our sun and sits just 12 light years from Earth. N ...read more
