RIP Tony Leggett (1938–2026): news.illinois.edu/tony-leggett-n… "Leggett was widely recognised as a world leader in the theory of low-temperature physics, and his pioneering work on superfluidity was recognised by the 2003 Nobel Prize in Physics." (from Wikipedia: en.wikipedia.org/wiki/Anthony_L…)

A new preprint from the geneticist David Reich focuses on the interactions of Neanderthal and African ancestral humans 250,000 years ago. Many parts I wholly agree with, but the key idea about Levallois technology is out of step with today's data. johnhawks.net/p/did-levalloi…

Asymmetric ice blocks floating in water can self-propel as they melt, due to a buoyancy-driven gravity current producing steady translation. A momentum-balance model predicts this mechanism, which persists even in warm saltwater. Editors' suggestion: go.aps.org/3Png1SW

Neanderthal warfare. 65,000 years ago, a group of Neanderthals in France expands outward, replacing other Neanderthals throughout Europe. Tens of thousands of years before humans wiped out the Neanderthals, they were wiping each other out. pnas.org/doi/10.1073/pn…

A newly discovered fossil ape from northern Egypt is reshaping the understanding of early hominoid evolution, researchers report in Science. The fossil finding suggests that the closest ancestors to modern apes may have emerged in northern Africa, outside the traditionally

Physicists captured a crystal made only of electrons, forming a honeycomb pattern without atoms, revealing a strange state of matter never directly seen before. In normal materials, atoms form the structure we see. But in this case, electrons themselves arrange into a fixed

"The Kakeya conjecture, after Wang and Zahl" (by Larry Guth): arxiv.org/abs/2604.03416

"This is a Seminaire Bourbaki survey of the proof of the Kakeya conjecture in three dimensions. The survey is written for a broad mathematical audience. We sketch all the ideas in the proof, with many pictures."

This is why international scientific exchange is so important. We must protect and encourage collaboration and mobility.

"Prediction of chaotic dynamics from data: An introduction" (by Luca Magri, Andrea Nóvoa, Elise Özalp): arxiv.org/abs/2604.11624

Quantum Mechanics Series Lecture 4 Lecture 1 established that ρ(x,t) = |ψ(x,t)|² behaves like a conserved probability density. Lecture 2 showed what drives that flow. We also saw that writing ψ = r exp(iθ) makes the probability current proportional to the phase gradient,
