A device the size of an espresso machine quietly whirs to life. The contraption isn’t filled with fresh, pungent grounds but, instead, spoonfuls of opaque, sterile goo. Its robotic arm moves briskly: It hovers, lowers, and then repositions a pair of syringes over six petri dishes. In short, rapid-fire bursts, they extrude the milky paste….
The notion of the speed of light as the cosmic speed limit is based on the assumption that particles of light, called photons, have no mass. But astrophysical observations cannot rule out the slim chance that photons do have a tiny bit of mass—a prospect with wide ramifications in physics. For instance, if photons weigh…
For linguists, Light Warlpiri provides a unique opportunity to study the creation of a new language — one that doesn’t fit the usual linguistic categories of “dialect,” “pidgin” or “creole.” But more generally, the recognition of a new language is a good reminder that language is a constantly evolving cultural creation. Like biological species, languages…
Jason Silva’s latest explores the Omega Point, a term coined by Pierre Teilhard de Chardin to describe the maximum level of complexity and consciousness towards which the universe was evolving.
AS EVERY schoolchild knows, the dinosaurs were wiped out in an instant, when a rock from outer space hit what is now southern Mexico. That happened 66m years ago, at the end of the Cretaceous period. Well-informed schoolchildren also know that this mass extinction was neither unique nor the biggest. The geological record speaks of…
Neither Ewan Birney nor Nick Goldman can remember exactly how they came up with the idea of storing all the world’s knowledge in DNA. They know it happened in the bar of the Gastwerk Hotel in Hamburg, and that many beers were involved. They may or may not have scrawled their ideas on a napkin….
Behind every great man, the saying goes, there’s a great woman. And behind every sperm, there may be an X chromosome gene. In humans, the Y chromosome makes men, men, or so researchers have thought: It contains genes that are responsible for sex determination, male development, and male fertility. But now a team has discovered…
Seventy years after its invention, the Buckminster Fuller Institute has organized a competition challenging graphic designers, visual artists, and citizen cartographers to create a new and inspiring interpretation of the Dymaxion Map.
There was a time not that long ago when it was easy to tell the difference between viruses and the rest of life. Most obviously, viruses were tiny and genetically simple. The influenza virus, for example, measures about 100 nanometers across, and has just 13 genes. Those two standards, it’s now clear, belong in the…
Charles Darwin was not yet 30 when he got the basic idea for the theory of evolution. But it wasn’t until he turned 50 that he presented his argument to the world. He spent those two decades methodically compiling evidence for his theory and coming up with responses to every skeptical counterargument he could think…
