Phys.org / Saturn-ring-like laser emission from chiral polymeric microspheres
Controlling light within microscopic spaces is crucial for next-generation optical devices such as photonic integrated circuits and localized sensors. Microspheres formed of luminescent π-conjugated polymers act as optical ...
Phys.org / Researchers break a fundamental rule to create a new concept: Heat that can be directed and 'programmed'
Normally, a material absorbs and emits heat in a linked way: A surface that absorbs heat well at a certain wavelength and direction will also emit heat in the same way. This fundamental relationship, known as reciprocity, ...
Phys.org / Medieval text family trees suggest 60% of works vanished over centuries
For every King Arthur or Roland, whose adventures readers can still enjoy today, another hero of ancient literature may have been lost forever. Before the printing press, texts were copied manually. This process introduced ...
Phys.org / New ultrathin lens focuses light into an optical needle
Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, with optical coherence ...
Phys.org / Satellite record reveals US tidal wetland productivity rose 6% in 20 years
Carbon sequestration, climate regulation, biodiversity support and shoreline protection: These are all benefits provided by tidal wetlands. As the climate changes, the amount of carbon captured by these vital ecosystems may ...
Phys.org / South Pole Telescope analysis releases new catalog of more than 7,000 galaxy clusters
Researchers working with data from the South Pole Telescope have released a major catalog of galaxy clusters, giving scientists a powerful new tool for studying how the universe grew and changed over billions of years. The ...
Phys.org / Magnetic octupole model captures domain-wall motion in noncollinear antiferromagnets
Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have developed the first magnetic multipole-based micromagnetic model for antiferromagnets. Published in Applied Physics ...
Phys.org / Day-night ocean warming helps explain why El Niño outpaces La Niña in models
Researchers have long known that there is an asymmetry in the El Niño-Southern Oscillation (ENSO), the confluence of wind and water currents that creates warm El Niño events and cooler La Niña events. Large-scale climate ...
Phys.org / Pressure unlocks 3D superconductivity in tantalum disulfide at triple the temperature
Superconductors have long been considered a promising technology for the energy systems of the future. They can conduct electricity without resistance, thus eliminating both conduction losses and waste heat. Up to now, however, ...
Phys.org / Scientists enable DNA synthesis using only temperature instead of chemical reagents
"Complex chemical processes are essential for making DNA." This long-held assumption in the field of biotechnology has been overturned by a Korean research team. A KAIST research team has developed the world's first foundational ...
Phys.org / Researchers develop AI tool that finds the equations behind complex systems
Clarkson University researchers have developed an artificial intelligence tool that can uncover the mathematical equations governing complex and chaotic systems directly from data. The technology, called KANDy—short for Kolmogorov-Arnold ...
Phys.org / AI framework could speed battery, combustion and materials research by automating simulations
Computers have made it easier than ever before to design the perfect material for a given problem: Scientists can create a virtual version and simulate how that material will behave. Building these atomically precise simulations, ...
