Phys.org / A new traveling-wave Josephson amplifier with built-in reverse isolation
Traveling-wave parametric amplifiers (TWPAs) are electronic devices that boost weak microwave signals (i.e., electromagnetic waves with frequencies typically ranging between 1 and 100 GHz). Recently, many engineers have been ...
Phys.org / Short-lived optical flare AT2022zod is an unusual tidal disruption event, astronomers find
An international team of astronomers has investigated a short-lived optical flare designated AT2022zod. As a result, they found evidence indicating that this flare is an unusual tidal disruption event. The findings were presented ...
Phys.org / Adult female bark spiders produce superior and tougher silk than males do
Dragline silk or major ampullate (MA) silk, the part of a spider's web that forms the main frame and spokes, is one of the toughest materials known to science. That is, it can absorb massive amounts of energy from a sudden ...
Phys.org / Humans rank between meerkats and beavers in monogamy 'league table'
Humans are far closer to meerkats and beavers for levels of exclusive mating than we are to most of our primate cousins, according to a new University of Cambridge study that includes a table ranking monogamy rates in various ...
Phys.org / The American West's most iconic tree is disappearing
A profound unraveling is underway in the American Southwest, happening across a thousand-mile arc from Santa Fe, New Mexico, to the central Sierra. In an unprecedented calamity, the most widely distributed, most iconic tree ...
Phys.org / CERN upbeat as China halts particle accelerator mega-project
The chief of the CERN physics laboratory says China's decision to pause its major particle accelerator project presents an "opportunity" to ensure Europe's rival plan goes ahead.
Phys.org / 'Light-bending' material that controls blue and ultraviolet light could transform advanced chipmaking
Researchers from TU Delft and Radboud University (The Netherlands) have discovered that the two-dimensional ferroelectric material CuInP₂S₆ (CIPS) can be used to control the pathway and properties of blue and ultraviolet ...
Phys.org / Antarctica's only native insect is already eating microplastics
A global research team led by researchers from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment has found that Antarctica's only native insect is already ingesting microplastics, even ...
Phys.org / Black hole ejects matter at 20% light speed in sun-like magnetic event
An international team of astronomers, led by SRON, has observed a sudden outburst of matter near the supermassive black hole NGC 3783 at speeds reaching up to 20% of the speed of light. During a 10-day observation, mainly ...
Phys.org / 'Monster Stars' from the cosmic dawn: Astronomers find first direct evidence
Using the James Webb Space Telescope, a team of international researchers have discovered chemical fingerprints of gigantic primordial stars that were among the first to form after the Big Bang.
Phys.org / Electron-phonon interactions in crystals found to be quantized by a fundamental constant
A researcher at the Department of Physics at Tohoku University has uncovered a surprising quantum phenomenon hidden inside ordinary crystals: the strength of interactions between electrons and lattice vibrations—known as ...
Phys.org / The surprising culprit limiting the abundance of Earth's largest land animals
Humans live in a world abundant in salt, but this everyday seasoning is a luxury for wild herbivores, and it's far from clear how these animals get enough.
