A technology that could propel crewed missions to Mars and robotic spacecraft throughout the solar system was recently put to the test at NASA’s Jet Propulsion Laboratory in Southern California. On Feb. 24, for the first time in years and at power levels exceeding any previous test in the United States, a team fired up […]
The man “inserted himself” into an investigation he was not involved in, yelling at Florence officers; when they tried to arrest him for suspected DUI, he resisted, eventually biting the dog

A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical stretching technology to dynamically control the emission color of gallium nitride (GaN) material from ultraviolet (UV) to blue light. This technological breakthrough provides a new semiconductor material control solution for future advanced power transistors, optoelectronic components, […]

The bright whites of mountain snow, muted browns of the arid plains, and gem-like blues and teals of glacial lakes typically dominate the Patagonian color palette. But for a short time in the austral autumn, temperate deciduous forests add splashes of warm tones. On April 12, 2026, a break in the clouds allowed the Landsat […]
Researchers have uncovered a counterintuitive phenomenon in collision dynamics: high-speed particles bounce back from wet walls much more strongly than expected. Integrating experimental observations with advanced numerical simulations revealed that increasing the impact speed induces a morphological transition in the post-collision liquid film, shifting it from a bridge to a dome shape. Further, it clarified […]
Understanding the universe as a whole requires simulations on cosmic scales. An international team of astrophysicists, with a leading role for researchers at Leiden University, Netherlands, has now released one of the largest cosmological simulation datasets ever produced. The dataset contains more than 2.5 petabytes of simulation data—roughly equivalent to half a million HD movies. […]
An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to perform high-resolution observations of the Needle galaxy. Results of the new observational campaign, presented April 15 on the arXiv preprint server, provide more insights into the properties of molecular gas in this galaxy.

NASA’s Curiosity and Perseverance rovers have captured two 360-degree landscapes that highlight how the missions are revealing details of the red planet’s formation, watery past, and potential for life. Located 2,345 miles (3,775 kilometers) apart from each other on Mars—about the distance from Los Angeles to Washington, D.C.—both rovers are exploring areas that are billions […]
The moon has played a huge role in the development of Earth. It stabilizes the planet, tempers dramatic climate swings, and possibly even provides the tidal heating that might have led to the first life forms. So it’s natural we would want to find a similar Earth/Luna system somewhere else in the cosmos. But astronomers […]
Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications in communications and medical diagnostics.

Discovered in 2019, the material known as nickelates has intrigued researchers for its potential to become a superconductor at elevated temperatures—a property that could significantly advance such fields as quantum science and energy transmission. However, it’s a very unstable material and difficult to work with. But the lab of Professor Charles Ahn has developed a […]
