Astrophysicist Kyu-Hyun Chae at Sejong University (Seoul, South Korea) has developed a new method of measuring gravity with all three components of the velocities (3D velocities) of  wide binary stars, as a major improvement over existing statistical methods relying on sky-projected 2D velocities. The new method based on the Bayes theorem derives directly the probability distribution of a gravity parameter (a parameter that measures the extent to which the data departs from standard gravitational dynamics) through the Markov Chain Monte Carlo simulation of the relative 3D velocity between the stars in a binary. When the method is applied to a sample of about 300 highest-quality wide binaries selected from European Space Agency's Gaia Data Release 3, the results indicate a 4.2σ discrepancy with standard gravity at acceleration lower than about 1 nanometer per second squared. Much improved results are expected in the near future with upcoming data of precise velocities of stars in the line-of-sight (radial) direction.

The EQUALITY project brings together scientists, innovators, and prominent industrial players to develop advanced quantum computer algorithms to tackle strategic industrial problems in areas such as energy storage, aerodynamics, and space mission optimisation. This upcoming webinar series will highlight some of the project's most promising results. Topics include novel quantum approaches to optimisation, analysis of noise in quantum bits and its impact on applied computations, tailoring of quantum circuits, and more — all with a focus on real-world industrial relevance. 

Flowers grow stems, leaves and petals in a perfect pattern again and again. A new Cornell study shows that even in this precise, patterned formation in plants, gene activity inside individual cells is far more chaotic than it appears.

UTA researcher awarded a grant to develop AI-driven models that better predict cures and guide safer, more precise treatment

The fifth annual Quantum Science Center, or QSC, Summer School at Purdue University, held Apr. 21 through Apr. 25, 2025, welcomed its largest group of students to date. Experts from industry, academia and national laboratories gathered at the Purdue Quantum Science and Engineering Institute to share their research in multiple areas of quantum science.

Dr Vladimir Dinets, a research assistant professor at the University of Tennessee, is a zoologist who studies animal behavior, ecology, and conservation. As of 2025, he also teaches mathematics at Rudgers University. He is the author of a recently published Frontiers in Ethology article that documents the impressive adaptation of an avian newcomer to the city. A Cooper’s hawk, a medium-sized raptor native to North America, appears to have learned how to adapt its hunting strategy and strike at a flock of birds precisely when cars at an intersection lined up after traffic lights switched to red, having been alerted by a sound signal that the red phase would last longer than usual. In the following guest editorial, he describes his observations.
