Administrator Heidelberg physicists just united two opposing quantum theories A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades. The findings could reshape experime... materials science
Administrator Why gold never tarnishes has finally been explained Gold may have a secret self-defense system that helps it resist tarnishing. Researchers discovered that atoms on gold surfaces reorganize themselves into patterns that block oxygen from reacting with ... materials science
Administrator This electric field trick boosted heat flow by nearly 300% Researchers discovered that electricity can dramatically reshape how heat flows through certain ceramic materials, increasing heat conduction by almost threefold in a preferred direction. The unexpect... materials science
Administrator New optical centrifuge unlocks the secrets of frictionless superfluids Physicists have developed a new optical centrifuge that can precisely spin molecules inside a superfluid for the first time. The advance could help unravel some of the biggest mysteries of quantum liq... materials science
Administrator Scientists may have finally solved the black hole information paradox Researchers have proposed that black holes stop evaporating at the last moment, leaving behind tiny remnants that preserve all the information they contain. The same seven-dimensional geometry behind ... materials science
Administrator Scientists create quantum sound device that could transform communications A new quantum device can generate precisely controlled bursts of sound-like particles, or phonons, by forcing electrons through an ultra-thin crystal at extremely low temperatures. The surprising beha... materials science
Administrator Heat breaks the rules at the nanoscale and scientists used it to their advantage Scientists used nanoscale gold metamaterials to supercharge heat transfer across tiny gaps, achieving up to four times more energy flow than similar conventional systems. The breakthrough could lead t... materials science
Administrator Physicists create a strange new quantum state called a fractional fermi sea Researchers have shown that ultracold atoms can be driven into a strange new quantum state called a fractional Fermi sea, where particles organize themselves in unexpected ways. The discovery points t... materials science
Administrator Scientists think they solved the mystery of the Amaterasu particle The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better abl... materials science
Administrator Scientists found a way to explain bird flocks that “defy” Newton’s third law Physicists have solved a long-standing problem involving systems that appear to violate Newton’s third law, such as bird flocks and bacterial swarms. By adding carefully designed “imaginary partners” ... materials science
Administrator Scientists built a battery-free device that turns sunlight into fuel Scientists have developed an artificial photosynthesis system that essentially regulates itself, eliminating the need for batteries used in many current designs. The key innovation is an electrolyzer ... materials science
Administrator This strange material can become strong or fall apart in seconds Scientists have found that staple-shaped particles can tangle together to create a material that is both strong and flexible. Unlike conventional materials, these particles can be locked into a sturdy... materials science
