Phys.org / Engineers introduce first synthetic charged domain wall in 2D material
In a first for the field, materials scientists from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have interfaced two materials to artificially generate a highly conductive ferroelectric ...
Phys.org / Webb reveals hidden details of W51 star formation
A team of University of Florida researchers used the James Webb Space Telescope to capture photos of a star-forming region known as W51 with never-before-seen clarity and resolution. The long wavelengths of JWST's infrared ...
Phys.org / NASA probe data suggests a more complex sun's magnetic engine
A Southwest Research Institute-led study found that protons and heavy ions react differently to solar magnetic reconnection events, revealing a more complex magnetic engine powering the solar wind. Magnetic reconnection converts ...
Phys.org / Climate change may produce 'fast-food' phytoplankton
We are what we eat. And in the ocean, most life-forms source their food from phytoplankton. These microscopic, plant-like algae are the primary food source for krill, sea snails, some small fish, and jellyfish, which in turn ...
Phys.org / Racetrack-shaped lasers developed for bright, stable frequency combs
A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Technical University of Vienna (TU Wien) could soon pack the power of ...
Phys.org / Physicist recreates neutron star reaction, reveals how explosive stars forge elements
A Mississippi State physicist has produced a direct laboratory measurement of a key nuclear reaction believed to occur during explosive bursts on neutron stars. These bursts forge heavier elements—the building blocks of planets ...
Phys.org / Great hammerheads maintain peak hunting across wide temperature swings, biologging data suggest
Most predators slow down when ocean temperatures shift. Great hammerhead sharks don't—not significantly anyway. These ocean predators are masters of the "thermal hustle," maintaining peak hunting performance across a surprisingly ...
Phys.org / Cow manure digesters really do cut methane—unless they leak
A new study shows that systems designed to capture methane from cow manure, called dairy digesters, are highly effective. But on the rare occasions they fail, the leaks are large enough to offset their climate benefits.
Phys.org / Impacts from meteors may have helped start life on Earth by creating hydrothermal vents
Meteor impacts may have helped spark life on Earth, creating hot, chemical-rich environments where the first living cells could take shape, according to research integrated by a recent Rutgers University graduate. Shea Cinquemani, ...
Phys.org / Chiral metasurfaces guide twisted light into free space
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew ...
Phys.org / Forest soil on doormats rebalances urban homes' indoor microbiome, study suggests
Introducing forest soil on an entryway doormat shifted the indoor microbiome of Finnish homes closer to bacterial profiles found outdoors, with less contribution from human-associated bacteria, a new study shows. In the future, ...
Phys.org / Targeting the tiniest divide: Research reveals potential vulnerability in bacterial reproduction
A Université de Montréal study has found a previously unknown mechanism in bacterial reproduction that could be attacked by future antibiotics. Bacteria reproduce by dividing into two: they form a wall, or septum, between ...
