(Phys.org)—When researchers deposit a drop of fluid containing thousands of free-swimming, genetically engineered E. coli onto an array of micromotors, within minutes the micromotors begin rotating. Some of the individual ...
(Phys.org)—Physicists have proposed a new type of Maxwell's demon—the hypothetical agent that extracts work from a system by decreasing the system's entropy—in which the demon can extract work just by making a measurement, ...
(Phys.org)—Although there are many counterintuitive ideas in quantum theory, the idea that influences can travel backwards in time (from the future to the past) is generally not one of them. However, recently some physicists ...
(Phys.org)—Researchers have built an electrocaloric refrigerator the size of a beverage coaster that can generate a temperature difference of about 2 K between the hot and cold ends of the device. The cooling mechanism, ...
(Phys.org)—In the late 1800s when scientists were still trying to figure out what exactly atoms are, one of the leading theories, proposed by Lord Kelvin, was that atoms are knots of swirling vortices in the aether. Although ...
An international team of researchers has found a way to determine whether a crystal is a topological insulator—and to predict crystal structures and chemical compositions in which new ones can arise. The results, published ...
Technology developed by a team of University of Utah electrical and computer engineers could make the holographic chess game R2-D2 and Chewbacca played in "Star Wars" a reality.
A scientist's dream of 3-D projections like those he saw years ago in a Star Wars movie has led to new technology for making animated 3-D table-top objects by structuring light.
You won't find ice cubes like this in your freezer.
Researchers at the University of Illinois at Urbana-Champaign and Princeton University have theoretically predicted a new class of insulating phases of matter in crystalline materials, pinpointed where they might be found ...
