Phys.org / Steering light in a flash: New chip redirects light beams in less than a trillionth of a second
Light can carry enormous amounts of information at extreme speeds, making photonic technologies promising for the development of faster communications, more powerful computing systems and more sensitive sensors. But for light ...
Phys.org / Quantum computers model nine fusion fuel material configurations for first time
A team of scientists from Oak Ridge National Laboratory, Cleveland Clinic and IBM has calculated nine molecular configurations of a promising material to produce fuel for fusion energy—the first known instance of such computations ...
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 / 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 / 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 / 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 / Migratory birds may carry fewer parasites between islands than expected, DNA shows
A new study published in the Journal of Helminthology by researchers from the Estonian University of Life Sciences and the Swedish University of Agricultural Sciences, together with collaborators from Greenland and the Faroe ...
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 / 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 / Where rivers face collapse: New tool shows where conservation dollars can do most good
Freshwater ecosystems are under growing pressure worldwide, but conservation resources are limited. A framework developed by IIASA researchers and partners can help identify where conservation could prevent biodiversity loss ...
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, ...
