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 / 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 / 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 / Can planes evacuate in 90 seconds? New simulations show the safest cabin layout
In case of an emergency, the Federal Aviation Administration requires aircraft to be able to evacuate within 90 seconds. However, as the median age of the global population increases, the growing number of elderly airline ...
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 / 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 / Scientists capture atoms in motion, unlocking next-generation memory technology
Monash University researchers have captured the exact atomic movements that write data to next-generation memory devices, which could pave the way for smaller, faster and more energy-efficient electronics. Published in Nature ...
Phys.org / NASA begins the countdown for humanity's first launch to the moon in 53 years
NASA began the countdown Monday for humanity's first launch to the moon in 53 years.
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 / 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 / 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 / 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, ...
