Phys.org / ShadowCam search casts doubt on abundant lunar ice
New observations by a team of US astronomers have cast fresh doubt on whether the lunar surface could host abundant water ice. Publishing their results in Science Advances, a team led by Shuai Li at the University of Hawaii ...
Phys.org / Experiment challenges hypothesis of cell-like membranes on Titan
New experimental results have cast doubt on earlier proposals suggesting that spherical, cell-like membranes could form in the methane lakes of Saturn's largest moon. Through results published in Science Advances, Tuan Vu ...
Phys.org / Discrete time crystal acts as a usable sensor for weak magnetic oscillations
The bizarre properties of discrete time crystals could be harnessed to detect extremely subtle oscillations of magnetic fields, physicists in the US and Germany have revealed. Publishing their results in Nature Physics, a ...
Phys.org / Enhanced fluorescence technique illuminates rapid, coordinated protein folding
A team of US researchers has gained new insights into how large protein molecules consistently fold themselves into useful shapes. Using a new approach to fluorescence microscopy, Hoi Sung Chung and colleagues at the National ...
Phys.org / Quantum dots generate entangled photon pairs on demand
For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment surrounding a single quantum ...
Phys.org / Superconductivity controlled by a built-in light-confining cavity
For the first time, physicists have demonstrated that a material's superconductivity can be altered by coupling it to an in-built, light-confining cavity. In experiments published in Nature, a team led by Itai Keren at Columbia ...
Phys.org / Quantum entanglement offers route to higher-resolution optical astronomy
Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard ...
Phys.org / Neutrons reveal magnetic signatures of chiral phonons
Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University mapped magnetic signatures ...
Phys.org / 'Nano-origami' reshapes liquid droplets into six-pointed stars
For the first time, researchers in France and Israel have observed how an emulsified liquid droplet can transform from a hexagon into a six-pointed star shape in response to rising temperature. Publishing their results in ...
Phys.org / Hidden atomic dichotomy drives superconductivity in ultra-thin compound
Physicists in China have unveiled new clues to the origins of high-temperature superconductivity in an iron-based material just a single unit-cell thick. Led by Qi-Kun Xue and Lili Wang at Tsinghua University, the team's ...
Phys.org / Self-propelling microbes switch up swimming strategy to optimize light intake
Researchers in Hong Kong and the UK have revealed how one species of self-propelling microbes can actively change the path of their swimming motions, depending on how much light they receive. Reporting in Physical Review ...
Phys.org / The screech of peeling sticky tape conceals a rapid train of tiny shockwaves, ultrafast imaging shows
A new experiment has uncovered the mechanism responsible for the screeching sound made by peeling sticky tape. Using a combination of ultrafast imaging and synchronized acoustic recordings, Sigurdur Thoroddsen and colleagues ...
Phys.org / Rydberg atoms detect clear signals from a handheld radio
For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the incoming signals, Noah ...
