The boundary between liquid and solid phases may not be as clear-cut as previously believed. This new state of matter is a hybrid of both, and the scientists who discovered it say it could have applications in catalysis and other thermally-activated processes. 🧪⚛️ physicsworld.com/a/new-hybrid...

The free-to-read Physics World Quantum Briefing on display on the island of Helgoland, just metres from where Werner Heisenberg did his seminal work on quantum mechanics 100 years ago. It includes a great article on quantum Cheshire cats from Iulia Georgescu.

The final after-dinner speaker was science journalist @philipcball.bsky.social who covered how quantum theory developed in 1924/25 shortly before Werner Heisenberg's work on quantum mechanics on the island of Helgoland exactly 100 years ago (as he also discussed in his recent feature for us).🧪⚛️

Next up was philosopher of science Elise Crull from the City College of New York, who discussed some of the early debates about the philosophical implications of quantum physics and the pioneering contributions of Grete Hermann, who was covered in a recent feature for Physics World. 🧪⚛️

Douglas Stone from Yale University was the first after-dinner speaker, talking about "stages in the conceptual development of quantum science". 🧪⚛️

Good news! We've tweaked our website so that it's now *even easier* for you to share our stories on Bluesky. Just look for the little butterfly at the top of stories like this one (written for us yesterday by student contributor Sabnam Shrestha) and click away! 💙☁️

CERN's solution is called BASE-STEP, where STEP stands for "Symmetry Tests in Experiments with Portable Antiprotons." Basically they trap the antiprotons, load them onto a truck, and drive it somewhere without loads of stray magnetic fields.

So that's what they did (with protons, this time). (3/n)

The scientists did commission an artist to create an impression of what a better dark-adapted camera on Perseverance might have seen. It's a bit more poetic, but in a world plagued by fake astro photos, we didn't want to imply it was the real thing!

The paper discussed in this article is this one from December 2024, not the 2023 paper cited above. The raw data used in both papers was collected by the JWST in 2022 and 2023.

We welcome good-faith requests for clarification and correction, but further insults will be blocked.

As physicists, we are unable to determine whether we have a cat or not without doing some complicated measurements. However, we do have a cactus! His name is Brian and he went a bit feral when we were out of the office during the pandemic, but we love him and he's our #ProofOfCat #ProofOfCactus.
