Researchers design six-state magnetic memory

(Phys.org)—Computers are often described with "ones and zeros," referring to their binary nature: each memory element stores data in two states. But there is no fundamental reason why there should be just two. In a new ...

Dendrite-proof batteries made possible by Zylon nanofibers

(Phys.org)—One of the biggest problems plaguing high-energy, lithium-metal batteries is dendrites, which form when some of the lithium from the electrode begins to branch outside the electrode and into the electrolyte, ...

Why is space three-dimensional?

(Phys.org)—The question of why space is three-dimensional (3D) and not some other number of dimensions has puzzled philosophers and scientists since ancient Greece. Space-time overall is four-dimensional, or (3 + 1)-dimensional, ...

Scientists turn to fireflies to improve OLED efficiency

(Phys.org)—Many insects, birds, fish, and amphibians emit light as a way to communicate with each other, but the species that produces light most efficiently is the firefly. In a new study, researchers have investigated ...

Smart skin is powered by the objects it touches

(Phys.org)—Researchers have fabricated a smart skin that is self-powered by its frictional contact with the objects that it touches. When a honeybee crawls across the smart skin, the skin not only senses the insect, it ...

Physicists quantify the usefulness of 'quantum weirdness'

(Phys.org)—For the past 100 years, physicists have been studying the weird features of quantum physics, and now they're trying to put these features to good use. One prominent example is that quantum superposition (also ...
