Imagine a world without the glow of your screen, the hum of your fridge, or the instant communication across continents.

A new paper presents a method for distinguishing between different sources of nanohertz gravitational waves. Pulsars may be revealing faint ripples in the fabric of the universe, ultra–low-frequency ...

The world’s first all-optical radio runs on laser light, not electricity, opening new possibilities for stealth sensors and ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But ...

A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed a new type of all-optical radio receiver based on the fundamental ...

The Milky Way ripples like a vast cosmic wave. Gaia’s precise measurements reveal a colossal motion sweeping through the ...

The math of even the simplest ocean waves is notoriously uncooperative. A team of Italian mathematicians has made major ...

Normal cellular processes in living things — from germinating plants to our own cells — create biophotons, though escaping light isn’t visible to us.

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by ...

We previously covered such “gravity telescopes” with the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Kamioka Gravitational Wave Detector (KAGRA). These early 2 nd generation of ...
