Cross-section of a planarianJubal Harshaw via Shutterstock Earlier this year, scientists published a bizarre finding: A decapitated flatworm that grows a new head seems to retain memories from its old one. Weird—but not even close to the weirdest finding in the annals of flatworm memory research. Half a century ago, experiments by James McConnell the […]

Underwater core samples, like these from the coast of England, often contain coded historical messages.Wessex Archaeology via Flickr “Out of sight, out of mind” is the usual attitude about what we flush down the toilet. But in the last century, some chemists have begged to differ: They want to know just where our personal waste […]

No known object in existence has as clear a division between “inside” and “outside” as a black hole. We live and see the outside, and no probe will bring us information about the inside. We can send radio messages or robotic spacecraft, but once they cross over into a black hole’s interior, we’ll never […]

Light snow on Mt. Jumbo highlights the different shorelines of prehistoric Lake Missoula.Photo by Don Hyndman, courtesy of the University of Montana You may not realize it, but all around you lie coded messages about the past. The curve of a hill, the shape of a lake, or the almost dinosaurian spine of that ridge […]

Postcards from Google Earth (one of five images in the collection)Clement Valla A wave of digital art, and its acceptance in the mainstream art world, has been building since computer technologies entered people’s lives over 20 years ago. Just last year, MoMA acquired 14 video games for its collection. Now comes the first-ever auction of […]

Jorge Louis Borges once described an empire that wanted to build a map. But the maps they had seen before were not precise enough. They had too much compression and approximation. There was too much inexactitude. And so the empire eventually made a map of the empire that was the size of the empire, and […]

Earlier today three US-based researchers shared the Nobel Prize in Physiology or Medicine for their research on vesicles, special structures that ferry all kinds of molecules around biological cells, and are fundamental to those cells’ functioning. Their findings provide some key background for our understanding of life—information that will fill textbooks for decades—though they lack […]

Before noon in the Soconusco region of southern Chiapas, down by the border where Mexico meets Guatemala, the lush, green terrain is rife with bodies in motion. It is an area abutting the Pacific, a vast collection of plantations, most of them growing coffee. Hsun-Yi Hsieh, a doctoral candidate at the University of Michigan, has […]

This is exactly the kind of photo you would not see in environmentalist literature.BMJ / Shutterstock When environmentalists petitioned to designate the polar bear a threatened animal under the Endangered Species Act in 2005, they were not, in fact, out to save the polar bear. They were out to save the world. Since the polar […]

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 […]
