Despite their popular reputation as dark inescapable pits, black holes really put out a lot of energy. They thrust out jets of matter. They get matter to heat up through friction as it swirls around them. And, in some cases, they contribute to bursts of incredibly high energy photons, thanks to a phenomenon first… »
The 2015 Nobel Prize in physics goes to Takaaki Kajita and Arthur B. McDonald for their work on neutrino oscillations. By tracking neutrinos in subterranean water tanks, the researchers watched neutrinos change flavour, in turn proving that the subatomic particles have mass. »
Your sewers have T-junctions—places were two pipes come together and form a “T” shape. So do your arteries. A new study has found that these junctions can trap tiny particles of matter, blocking normal healthy flow. »
In the early 1920s a researcher spent his days watching vortexes in water circle around each other. A hundred years later, we do the same thing—but we do it from space as we wonder which way a tropical storm is going to go.
Uranium and plutonium have gotten famous, or infamous, because they are used in atom bombs. We could have been saying that about another material—one that few actually know. Learn about the material that didn’t quite make it into The Bomb. »
Killjoy physicists have long pointed out the sheer unlikelihood of building a working light saber. But now, they’ve taken a small step toward realizing the dream of Star Wars fans worldwide, by figuring out how to get photons to stick together like molecules in a super-chilled gas. »
Pitchblende is a material that has helped scientists isolate plutonium, radium, and helium. Its major component, however, is uranium. And uranium reacts with acid. Dramatically. »
Scientists now have a way to cloak something very small, making it effectively invisible. But what if scientists and engineers created a much larger version? What if we all had access to invisibility cloaks? »
Have you ever wanted to meander between two spiral galaxies, or follow in the footsteps of a comet? Now visitors to southwest Scotland’s Nith Valley can do just that. Welcome to the “Crawick Multiverse,” a massive installation created by renowned landscape architect Charles Jencks that gives symbolic physical form to… »
The Weissenberg Effect happens when a fluid behaves in a very counter-intuitive way. Instead of being driven away from a spinning object, it starts climbing. Take a look at something you may have seen at home—but you’ve probably never noticed. »
The paradox of Schroedinger’s Cat famously demonstrates that a quantum cat sealed in a box is both alive and dead at the same time until we look inside, at which point it becomes one or the other. Such is the weirdness of quantum mechanics. But if a mere act of observation determines the outcome of an experiment, what… »
The latest model of the Invisibility Cloak is here, and it has two major improvements on the last few models. It can actually wrap around the stuff it’s concealing — and you can’t see the cloak itself. Take a look!
When scientists spotted this pair of black holes, it was a rare chance to observe black holes in the process of colliding. Soon, however, as they looked closer, scientists were consumed with a brand new question: Uh, hey, what’s that blinking light?
It looks like the inner workings of an elaborate mechanical clock, but it’s actually one of many hypnotic kinetic sculptures created by Connecticut-based artist and woodworker David C. Roy over the years. And they can run anywhere from five to 40 hours on a single wind, a testament to their excellent design. »
Temple University physics professor Xiaoxing Xi made headlines back in May, when he was indicted for allegedly sharing “sensitive” information with colleagues in China about a piece of laboratory equipment used in his superconductivity research. Xi maintained his innocence from the start. On Friday, he was vindicated:… »
