Cosmic radiation at flight altitudes rises when the sun is less active

Radiation from space is constantly entering Earth's atmosphere, but how much of it reaches the altitudes used by commercial aircraft depends not only on height and location, but also on the activity of the sun. A new study ...

BESIII sets world's most stringent direct limit on Lambda hyperon electric dipole moment

The BESIII Collaboration, led by the Institute of High Energy Physics of the Chinese Academy of Sciences, has achieved the world's most precise measurement of the electric dipole moment (EDM) of the Lambda (Λ) hyperon using ...

Quantum control algorithm looks to explain how birds migrate

The hidden world of quantum mechanics exists at scales many orders of magnitude smaller than living organisms, yet scientists have long theorized that quantum effects play an important role in biology. Birds' ability to sense ...

New research could improve detection of chiral molecules in pharmaceuticals and biotechnology

Ohio University Distinguished Professor Alexander Govorov of the Department of Physics and Astronomy and the Nanoscale and Quantum Phenomena Institute (NQPI) in the College of Arts and Sciences has co-authored a new study ...

LEDs let archaeologists see the past in a new light

An archaeological excavation is a little like eating a layered cake: Once you have removed a layer, you cannot put it back. The problem becomes even trickier if two layers look almost exactly the same. Researchers from Aarhus ...

Faint far-infrared radiation drives a correlated insulator-to-metal transition in magic-angle graphene

One of the central ideas in modern physics is the phase transition—a sudden transformation of the state of a material. We encounter phase transitions throughout everyday life: water freezes into ice, wax melts in the warmth ...

Femtosecond nano-imaging reveals ultrafast optical control of phonon polaritons

A collaborative research team has successfully visualized in real space the ultrafast optical modulation of hyperbolic phonon polaritons (HPhPs) in a van der Waals heterostructure composed of hBN and WS2. The research is ...

Metamaterials may enable invisibility cloaks, thinner lenses and smarter wireless networks

Who has not dreamed of an invisibility cloak like the one used by Harry Potter? It sounds like magic, but it could become reality with the help of so-called metamaterials. In the summer of 2026, some of the world's leading ...

New method tests magnet-powered braking for safer, more reusable spacecraft reentry

Researchers from Tokyo Metropolitan University have created a new system to test magnetohydrodynamic aerobraking for spacecraft reentering the atmosphere. Their platform generates intense magnetic fields with a powerful electromagnet ...

First observation of optical Magnus effect could sharpen quantum computer control

Table tennis professionals are true masters at redirecting fast-moving projectiles. Putting a targeted spin on a serve can make the little white ball fly straight toward the edge of the table but then, at the last moment, ...
