The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is scarce. Now, astronomers using archival data from NASA’s Hubble Space Telescope and supporting observations from NASA’s James Webb Space Telescope have finally located the first stellar-mass […]

Researchers have captured how a molecule redistributes energy after absorbing light, differentiating the roles of individual atoms in the process. They used X-ray flashes from the European XFEL to show that different atoms in the same molecule can reveal different aspects of the process. The study provides evidence that excitation by light can enhance an […]
The Grammy winner “has paid already the cost of the permit that was lodged, which was over $160,000 for that event and for the response to that event,” Mayor Zohran Mamdani said

Sugars are key biomolecules in living organisms, as they form the backbone of DNA and RNA and play a fundamental role in metabolic processes. In theories of the origin of life, sugars are also essential for the synthesis of the first nucleic acids. Despite their importance, one of the major questions in origin-of-life research is […]
A material made from yttrium, barium and copper oxide (better known as YBCO) has intrigued scientists since its discovery in 1987, largely because it retains its superconductive properties at a higher-than-normal temperature. However, it is extremely brittle, which makes it tricky to put to practical use.

Not every World Cup goal is a classic. Sometimes a half-hearted shot goes in as a result of little more than a goalkeeper’s error. And on those occasions, goalies may be inclined to find an excuse.

For over a century, the accepted value for a firefly’s brightness has mostly stood, tracing its origins to experiments carried out in 1912. Through rigorous new analysis published in the American Journal of Physics, David Silver of Remiza AI in New York has discovered that this value has likely been vastly overestimated. His results provide […]
The mysterious substance that binds galaxies together could naturally be “in tune” with a hidden fifth dimension, according to a new University of Sheffield theory aiming to shed light on one of science’s biggest enigmas: dark matter.

Cornstarch can thicken soup or serve as a base for a DIY shampoo, but there’s more to the humble pantry staple. Given the right conditions, it seems to defy the laws of physics. Mixing cornstarch with water creates “oobleck”—a shape-shifting substance classified as a non-Newtonian fluid that changes states when subjected to a force.

Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly throughout the universe and that it looks almost the same in all directions.

Korean researchers have developed, for the first time in Korea, a 200Gbps-class photodetector device for use in hyperscale AI data centers and 5G/6G mobile communications infrastructure. The technology enables ultrahigh-speed data reception fast enough to transmit five 5GB full HD movies per second. The results of this study were presented at OECC 2025, held in […]
