Time crystals, a theoretical phase of matter proposed in 2012, can now be reliably created and measured, thanks to researchers at UC Berkeley. Above: a great primer on time crystals.
The discovery built on the work of several teams of researchers:
Time crystals repeat in time because they are kicked periodically, sort of like tapping Jell-O repeatedly to get it to jiggle, Yao said. The big breakthrough, he argues, is less that these particular crystals repeat in time than that they are the first of a large class of new materials that are intrinsically out of equilibrium, unable to settle down to the motionless equilibrium of, for example, a diamond or ruby.
“This is a new phase of matter, period, but it is also really cool because it is one of the first examples of non-equilibrium matter,” Yao said. “For the last half-century, we have been exploring equilibrium matter, like metals and insulators. We are just now starting to explore a whole new landscape of non-equilibrium matter.”
Maybe the next step is the development of these time crystals:

This is some pretty amazing and highly rare video — seldom do you get footage of five, count ’em FIVE, California mountain lions all hanging out together. The big cats were captured on home surveillance video, in a rare gathering of the typically solitary critters.
Some extra-planetary Caltech news to take your mind off Earth Reports Caltech: “A rare asteroid orbiting snugly within the inner confines of our solar system has been discovered by Caltech’s Zwicky Transient Facility, or ZTF, a survey camera based at Palomar Observatory. The newfound body, named 2020 AV2, is the first asteroid found to orbit […]
We’ve all got a perfect website in our minds. In the past, the problem has been the barrier of language – specifically, the computer languages used to create those glittering, animation-filled pages you flock to. Now, Mac users have an alternative. Blocs 3 is a website builder that can provide an easy visual interface for […]
You can do all the pre-workout stretching in the world, but that doesn’t mean you’ll escape stiff muscles and nagging pain after a particularly grueling gym session. When those knots and their accompanying aches and soreness start barking, your options usually boil down to either a deep tissue massage or just grinning and bearing it. […]
Spring doesn’t officially start until March, but you might want to start your spring cleaning a little early in the office supply closet. You’re going to need the extra space. HP is holding a massive “Back to Business” sale on a vast array of its gear. And when we say “gear,” we’re not talking about […]
