Researchers at Paderborn University have developed a new method of distance measurement for systems such as GPS, which achieves more precise results than ever before. Using quantum physics, the team led by Leibniz Prize winner Professor Christine Silberhorn has successfully overcome the so-called resolution limit, which causes the ‘noise’ we may see in photos, for example. Their findings have just been…

EFF Reveals Behind-the-Scenes Account of the Fight to Save .ORG
As part of its “Year in Review” series, the EFF shares their dramatic behind-the-scenes details about 2020’s fight over the future of .org domains. It begins when the Internet Society (ISOC) announced plans to sell the Public Interest Registry — which manages the .org top-level domain (TLD) — to private equity firm Ethos Capital. “If you come at the nonprofit sector,…
Most-Played Song of 2020? For Many It’s White Noise
An anonymous reader shares a report: In an average year, Spotify Wrapped is a sharing-optimized novelty hinging on nostalgia for a time that’s barely passed. But in 2020, this data mirror instead presented many users with unexpected empirical evidence of their pandemic coping mechanisms: a strange hit parade of ambient music, background noise and calming sound effects that soothed them through…
Metasurface enabled quantum edge detection
Metasurfaces provide unique platforms to realize exotic phenomena including negative refraction, achromatic focusing, and electromagnetic cloaking due to the engineered dielectric or metallic architectures. The intersection of metasurfaces and quantum optics can lead to significant opportunities that remain to be explored. In a new report now published on Science Advances, Junxiao Zhou, Shikai Liu and a research team in quantum information,…
America Creates a 770-Mile Corridor for Testing Supersonic Aircraft Up to Mach 3
America’s Federal Aviation Agency signed an agreement with the state of Kansas’s department of transportation to establish a 770-nautical mile Kansas Supersonic Transportation Corridor for testing aircraft up to Mach 3, reports Aviation International News:
The agreement would provide a critical testing site for the emerging group of supersonic aircraft as civil supersonic flight remains banned over land. Flight testing for models…
Drug Reverses Age-Related Mental Decline Within Days
The University of California San Francisco issued this glowing announcement of some new research: Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic…

Hidden symmetry could be key to more robust quantum systems, researchers find
Researchers have found a way to protect highly fragile quantum systems from noise, which could aid in the design and development of new quantum devices, such as ultra-powerful quantum computers. …
Experiment to test quantum gravity just got a bit less complicated
Is gravity a quantum phenomenon? That has been one of the big outstanding questions in physics for decades. Together with colleagues from the UK, Anupam Mazumdar, a physicist from the University of Groningen, proposed an experiment that could settle the issue. However, it requires studying two very large entangled quantum systems in freefall. In a new paper, which has a third-year…
Did the Wow! signal come from this star?
Where did the famous mystery Wow! signal, detected in 1977, come from? Astronomer Alberto Caballero might have pinpointed the host star. It’s a sunlike star 1,800 light-years away, in the direction to the center of our Milky Way. Source: https://earthsky.org/space/source-of-wow-signal-in-1977-sunlike-star-2mass-19281982-2640123…
