The ATLAS Collaboration finds evidence of Higgs-boson decays to muons and improves sensitivity to Higgs-boson decays to a Z boson and a photon. Since the discovery of the Higgs boson in 2012, physicists have made major strides in exploring its properties. Does that mean the subject is done and dusted? Far from it! In new results presented at the 2025 …

The images were observed at wavelengths of 3.0, 4.26, and 4.7 micrometers, corresponding to prominent emission lines of H2O, CO2 and CO gas, from left to right respectively. 3I/ATLAS is undetected in H2O and CO. By contrast, a bright CO2 …

There are several candidates for the biggest star in the universe. One of them, VY Canis Majoris, is over 1,500 times the width of the sun. If it were placed in our solar system, it would stretch to nearly the orbit of Saturn. But how can such a beast exist? The answer, as always, is physics. VY Canis Majoris is …

From better sleep to healthier hearts, brains, bowels, and immune systems, studies keep finding strong associations between diets packed with fruits and vegetables and reduced risks of major diseases. A new analysis now adds to growing evidence that veganism and vegetarianism lower the risk of some cancers. “This is all relatively unique information and possibly the most robust that’s out …

A red supergiant star has expelled the largest cloud of gas and dust ever seen in the process of being blown off one of these stellar behemoths. The vast size and intricacy of the cloud suggests that there could be a hidden group of stars that are contributing to the growth of the cloud. In a false-color image taken by …

A woman was killed while walking a child to a bus stop in west Louisville, and police are looking for the shooter.Police said the shooting happened around 8 a.m. Wednesday in the area of West Chestnut Street and 10th Street, in the Russell neighborhood. It’s the same area where shots were fired last week on Jefferson County Public Schools’ first …

Marijuana users have “superior performance across multiple cognitive domains,” according to a new large-scale study funded by the U.S. federal government, with the effects of cannabis on cognition “presented concurrently across a range of brain systems.” The research, published this month as a preprint by Nature Portfolio, analyzed brain imaging and cognitive data from 37,929 participants in the United Kingdom aged …

So much for heliocentrism. An international team of astronomers using observations made with the James Webb Space Telescope have found evidence of massive planets out there that’re capable of forming their own planetary systems — without a star.  These planets would be the center of something like a mini version of our solar system where other, smaller planets revolve around …

Earlier this summer, Republican lawmakers gathered around Donald Trump and applauded as he sat before a desk outside the White House and put his signature on what he calls his “one, big, beautiful bill”. But there were few claps for Mike Flood this week when the Republican congressman appeared before an auditorium of his Nebraska constituents to extol the tax …
