How the science of sound explained an ancient Peruvian oracle.

Grigori Perelman became famous, despite his adamant opposition, for proving a conjecture from Henri Poincaré, pictured here. In November 2002, a Russian mathematician named Grigori Perelman posted the first of three short preprints to the arXiv (an online repository for drafts of academic papers in math and science), offering a proof for the famous Poincare […]

Using molecular codes, plants cry for help, ward off bugs, and save each other.

It began like so many creative endeavors—with a barstool discussion. “Who would be your television dad?” New York artist Amanda Tiller mused. A friend chose Cliff Huxtable, Bill Cosby’s alter ego on The Cosby Show. Later, Tiller thought a lot about Cosby and his famously be-sweatered character: We all know Cliff, a beloved father, doctor, […]

What do you say when faced with something so unlikely, so improbable, that you simply cannot imagine it ever happening? Perhaps you’ll admit your neighbor was right about who owns the shovel you’ve both used—when pigs fly. Or maybe your boss will give you that raise when hell freezes over. But would you ever say […]

Nautilus popped in to the Intergalactic Travel Bureau, a pop-up shop promoting moon-hopping, sun-surfing, and all forms […]

As recently as the late 80s, finding a planet orbiting another star seemed like the stuff of sci-fi fantasy, about as realistic as a diminutive alien riding a flying bicycle, or a sports car that worked as a time machine. Thanks to many smart astronomers using a new generation of powerful telescopes, we now know […]

In the huge range of different human cultural inclinations, one of the most widespread is a fondness for stories. We just love to get lost in a good book or movie. When we do, we tend to ignore where we are and become completely absorbed in the story. Psychologists call this “transportation,” and have conducted […]

Sperm are the cheetahs of the microscopic world: Made of little more than molecular muscle and batteries, tipped with a payload of genetic information, they are optimized for speed. But to orient themselves before their epic, seven-inch sprint (it’s more impressive if you’re less than one three-thousandth that size), they first need to sniff out […]

The remarkable ways animals get around.
