Cool to see work in the world that builds on and is in conversation with work I did with my former PhD student Dr. Nathan Rutherford (now at @fqxi.org) and @profannawatts.bsky.social! 🔭

Bayesian Constraints on Bosonic Dark Matter in Neutron Stars within a Covariant Density-Functional Equation-of-State Ensemble
We investigate neutron stars admixed with repulsively self-interacting bosonic dark matter (DM) using current multi-messenger observations. The dark component is modeled as a complex scalar field coup...

FQxI members Vlatko Vedral and Roger Penrose are among authors of an experiment that has made the first direct measurement of the quantum phase of a freely falling object.

We've set a guest challenge at the Moth Hack: make something that teaches a general audience about quantum computing or quantum mechanics, using one of Moth's Atlas Engines. The winner gets a £150 voucher. Entries are open online until 2 October.

Is gravity quantum? It's one of the big open questions in physics. The Bose-Marletto-Vedral experiment, proposed by Chiara Marletto, Vlatko Vedral and colleagues, would test whether gravity alone can entangle two tiny masses.

The theoretical physicist Rafael Sorkin died on September 12, 2026, at his home in Kitchener, Ontario. He is best known as one of the main developers of causal set theory, an approach to the emergence of spacetime from discrete points. qspace.fqxi.org/news/165328/...

The incentive problem at the heart of modern science
"Publish or perish" has become an academic cliché. But the biggest casualty isn't researchers — it's scientific discovery itself.

#ICYMI: The collective behavior of neuron networks seems governed by just a few variables, suggesting mean-field theory applies. Researchers found simple versions fail, but an extended version successfully captures real neural activity patterns: go.aps.org/4vIiqYS

Guilty as charged on the headline. "Most physicists don't agree on the ten things they're least likely to agree on" is a worse headline though. 😉
