The top regulatory agency for nuclear materials safety in the U.S. voted unanimously to regulate the burgeoning fusion industry differently than the nuclear fission industry, and fusion startups are celebrating that as a major win.

As a result, some provisions specific to fission reactors, like requiring funding to cover claims from nuclear meltdowns, won’t apply to fusion plants. (Fusion reactors cannot melt down.)

The Nuclear Regulatory Commission, the top governing body for nuclear power plants and other nuclear materials, announced the results of its vote on April 14.

Amazing to see a metal-rich galaxy so early in the Universe’s history.

Scanning the first images of a well-known early galaxy taken by NASA’s James Webb Space Telescope (JWST), Cornell astronomers were intrigued to see a blob of light near its outer edge.

Astronomers say they have solved an outstanding problem that challenged our understanding of how the universe evolved—the spatial distribution of faint satellite galaxies orbiting the Milky Way.

These satellite galaxies exhibit a bizarre alignment—they seem to lie on an enormous thin rotating plane—called the “plane of satellites.”

This seemingly unlikely arrangement had puzzled astronomers for over 50 years, leading many to question the validity of the standard cosmological model that seeks to explain how the universe came to look as it does today.

Two new studies suggest that certain tetrahedral arrangements of galaxies outnumber their mirror images, potentially reflecting details of the universe’s birth. But confirmation is needed.

Physicists believe they have detected a striking asymmetry in the arrangements of galaxies in the sky. If confirmed, the finding would point to features of the unknown fundamental laws that operated during the Big Bang.

“If this result is real, someone’s going to get a Nobel Prize,” said Marc Kamionkowski, a physicist at Johns Hopkins University who was not involved in the analysis.

Why haven’t we found wormholes? It might be because they look just like blackholes!

A group of researchers at Sofia University has found evidence that suggests the reason that a wormhole has never been observed is that they appear almost identical to black holes.

In their paper published in the journal Physical Review D, , Petya Nedkova, Galin Gyulchev, Stoytcho Yazadjiev and Valentin Delijski describe studying theoretical linear polarization from an accretion disk that would be situated around a class of static traversable wormholes and compared the findings to images of black holes.
