FAST & ACCURATE: Predicted motions of hundreds of particles inside a fusion reactor show that a new computational method (orange, red) closely matches the results of traditional Newtonian calculations (blue, green)—but with a speed boost of 10x. (Image credit: University of Texas at Austin)

Major Fusion Energy Hurdle Cleared

NETWORK IT: A photonic chip integrates a highly nonlinear crystal with a fiber array unit to generate entangled photon pairs spanning visible and telecom wavelengths. These pairs are routed through silicon nitride and silicon photonic integrated circuits, creating a compact and flexible platform for linking quantum nodes—such as those accessed via visible light—over existing telecom infrastructure.

New Keck Findings Challenge What We Know About Stars

Solving the Black Hole Puzzle: Scientists Propose End to Troubling Singularities

Using microscopy with single-atom resolution, researchers observed ultracold quantum gases made of two different types of atoms. The bosons (shown on the left) tend to cluster together — a behavior known as bunching — while the fermions (on the right) tend to avoid each other, showing anti-bunching.

Physicists Capture First-Ever Images of Atoms Interacting in Free Space

The gravitational quantum field is calculated assuming flat spacetime. The curved classical spacetime metric is then derived from the expectation value of this quantum field. Image credit: Mikko Partanen and Jukka Tulkki, Aalto University.

Physicists Develop New Theory That Could Finally Unify Gravity with Other Fundamental Forces

$This new image features one of the Milky Way’s cosmic “bones,” known as G359.13142-0.20005—or G359.13 for short—also nicknamed the Snake. X-ray data from NASA’s Chandra Observatory (in blue) and radio data from South Africa’s MeerKAT array (in gray) reveal a striking feature: a visible break in the otherwise continuous structure of G359.13. By combining these two datasets, researchers are uncovering clues about what may have caused this fracture.$
