Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in Astronomy & Astrophysics, ...

Historical observations from an observatory in Germany have now independently verified evidence for brief, mysterious flashes of light in the night sky, first picked up by an American astronomical survey in the 1950s. Through ...

Physicists have developed a new theoretical framework which unifies a wide array of seemingly unrelated "Mpemba effects": counterintuitive cases where systems driven further from equilibrium relax faster than those closer ...

With a new lab-based experiment, researchers in the UK and France have recreated the characteristic cascades of energy and angular momentum that underpin key features of Earth's atmosphere. Reporting in Physical Review Letters, ...

Through new improvements to existing AI models, researchers in China have created a framework that can methodically identify useful new forms of solid carbon. With their approach, Zhibin Gao and colleagues at Xi'an Jiaotong ...

For the first time, a team of physicists in Austria has carried out an experiment that appears to verify the principle of indefinite causal order: an idea that suggests that timelines of events can exist in multiple orders ...

A team of cosmologists in China has introduced a mathematical framework that investigates two of the deepest mysteries in cosmology at the same time. Publishing their research in The Astrophysical Journal, Yun Chen and colleagues ...

The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, Tim Palmer at the University ...

Researchers have proposed that a newly identified class of magnetic materials could extend the zero-resistance currents of superconductors to electron spins. Publishing their calculations in Physical Review X, Kyle Monkman ...

Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck ...

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 ...

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 ...

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 ...

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 ...

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 ...
