New research by Southwest Research Institute (SwRI) and the National Science Foundation’s National Center for Atmospheric Research (NSF-NCAR) has developed a new tool providing a first step toward the ability to forecast space weather weeks in advance, instead of just hours. This advance warning could allow agencies and industries to mitigate impacts to GPS, power grids, astronaut safety and more.
Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced “combs” of laser light on a photonic chip, a breakthrough that could miniaturize optical platforms like spectroscopic sensors or communication systems.
Researchers have developed a unified theory of microcavity OLEDs, guiding the design of more efficient and sustainable devices. The work reveals a surprising trade-off: squeezing light too tightly inside OLEDs can actually reduce performance, and maximum efficiency is achieved through a delicate balance of material and cavity parameters. The findings are published in the journal Materials Horizons.
Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University researchers now have evidence of the surprisingly simple process that could be responsible for their creation.
NASA took another crack at fueling its giant moon rocket Thursday after leaks halted the initial dress rehearsal and delayed the first lunar trip by astronauts in more than half a century.
For the first time, an international team of astronomers have mapped the vertical structure of Uranus’s upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using Webb’s NIRSpec instrument, the team observed Uranus for nearly a full rotation, detecting the faint glow from molecules high above the clouds.
That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion remains hotly debated, even challenging the standard model of cosmology. A research team at the Technical University of Munich (TUM), the Ludwig Maximilians University (LMU) and the Max Planck Institutes, MPA and MPE, has now imaged and modeled an exceptionally rare supernova that could provide a new, independent way to measure how fast the universe is expanding. The studies are published on the arXiv preprint server.
Many physicists are searching for a triplet superconductor. Indeed, we could all do with one, although we may not know it yet—or understand why. Triplet superconductors could be the key to achieving the most energy-efficient technology in the future.
The Counter Drone State and Local Defender Act would allow state and local agencies to apply for authorization to disable drones during major events, including the 2026 World Cup
Officer Houston Tipping died three days after he suffered a spinal injury during training; his family sued, claiming he was killed in retaliation for reporting an alleged sexual assault
A plume of upper-atmospheric lithium pollution observed in February 2025 has been attributed to the reentry of a specific rocket stage. The results, published in Communications Earth & Environment, are the first known direct detection of upper-atmospheric pollution from space debris reentry.
It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and other complex materials. But a team of Yale researchers led by Professor Amir Pahlavan shows that even gentle chemical gradients, such as a small change in salt concentration, can dramatically reshape how particles move through porous materials. Their results are published in Science Advances.
Trooper Michael Diego was participating in a “competitive process” for FHP’s Criminal Interdiction Unit at the agency’s training academy when he became unresponsive
An international collaboration using the Low Frequency Array (LOFAR) has published an exceptionally detailed radio sky map, revealing 13.7 million cosmic sources and delivering the most complete census yet of actively growing supermassive black holes. It showcases an extraordinary variety of systems powered by these black holes, whose radio emission can extend for millions of light-years.
By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. Publishing their results in Physical Review Letters, a team led by Kai Dietze at the German National Metrology Institute, hope their approach could help usher in a new generation of optical clocks—opening up new possibilities in precision experiments and metrology.
