Researchers create new form of matter—supersolid is crystalline and superfluid at the same time

By using lasers to manipulate a superfluid gas known as a Bose-Einstein condensate, the team was able to coax the condensate into a quantum phase of matter that has a rigid structure—like a solid—and can flow without viscosity—a key characteristic of a superfluid. Studies into this apparently contradictory phase of matter could yield deeper insights Read more about Researchers create new form of matter—supersolid is crystalline and superfluid at the same time[…]

Sponge can soak up and release spilled oil hundreds of times

A new material can absorb up to 90 times its own weight in spilled oil and then be squeezed out like a sponge and reused, raising hopes for easier clean-up of oil spill sites. But to determine whether this material could help sort out a big spill in marine waters, they needed to perform a Read more about Sponge can soak up and release spilled oil hundreds of times[…]

Switched-on DNA: Sparking nano-electronic applications

Physicists show that real-time error correction in quantum communications is possible

Now researchers have shown that there is a grey area where Nature cannot tell the difference between the classical and the quantum. This opens the possibility of first performing quantum experiments with a type of classical light called “classically entangled” light. By preparing and sending a so-called “classically entangled” beam the team could show that Read more about Physicists show that real-time error correction in quantum communications is possible[…]

Thermoelectric paint enables walls to convert heat into electricity
