Physicists finally solve the strange mystery of “breathing” lasers
An international team of researchers, including a scientist from Aston University, has developed a new mathematical framework that…
Scientists discover strange “narwhal” waves that trap light beyond known limits
For decades, shrinking photonic devices has been far more difficult than miniaturizing electronic components. The challenge comes down…
Accurate and fast event-based shape measurement of mixed reflectance scenes
Principles In our proposed approach, we tightly integrate event-based triangulation and deflectometry to simultaneously scan all surface types…
Physicists finally solve the strange mystery of “breathing” lasers

What If the Direction of a Magnet Could Shape the Building Blocks of Life?
Insider Brief Researchers from the Hebrew University of Jerusalem and Weizmann Institute of Science found that the direction…
Most of the matter in the universe has never been observed directly, and the existence of “dark matter” is essentially a placeholder name for the gap between what we can see and what the math requires — a placeholder we’ve been using confidently for about ninety years
The standard cultural framing of dark matter tends to treat it as a known scientific substance. The framing…
New quantum sensor could count individual photons and hunt dark matter
Researchers in Finland have achieved a major advance in ultra-sensitive measurement technology by detecting an amount of energy…
Nonlinear atomic tunnelling boosted by bright squeezed vacuum
Experimental details Both coherent and quantum light sources are pumped with the same femtosecond laser pulse (790 nm, 28 fs,…
A Physical Warp Drive Was Supposed to Be Impossible. Then These Scientists Found a Loophole.
In a surprising paper from 2021, scientists Alexey Bobrick and Gianni Martire suggested that they’d nailed down a…
Physicists confirm ‘negative time’ is real in mind-bending quantum experiment
When a beam of light passes through a cloud of atoms, photons (particles of light) sometimes appear to…
Scientists Just Used Sunlight To Pull Off a Quantum Physics Feat Once Thought Impossible
Correlated photon pairs, generated via sunlight-pumped spontaneous parametric down-conversion in a nonlinear crystal, demonstrate ghost imaging. Credit: W.…
