The Pioneer 10 and 11 spacecraft were found to be decelerating slightly more than gravity could explain, and for thirty years physicists wondered if Newton was wrong before realizing in 2012 that the answer was the probes’ own waste heat gently pushing them backward at a billionth of Earth’s gravity.
Two NASA probes built in the early 1970s spent three decades drifting slightly off course, decelerating by about…
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…

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…
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…
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…
NASA’s Fermi Glimpses Power Source of Supercharged Supernovae
An international team studying data from NASA’s Fermi Gamma-ray Space Telescope concludes the mission detected a rare, unusually…
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…
