Artificial intelligence, cognitive offloading and implications for education: https://www.uts.edu.au/news/2026/03/experts-warn-unstructured-ai-use-in-schools-risks-cognitive-atrophy/contentassets/ai-cognitive-offloading-and-implications-for-education.pdf

i really dug this paragraph in @pluralistic 's latest treatise on AI:

"There's a different advantage to confining your concerns to imaginary things: imaginary things don't exist, so they don't contest your public statements about them, nor do they make demands on you. Think of how the right concerns itself with imaginary children (unborn babies, children in Wayfair furniture; children in nonexistent pizza parlor basements, children undergoing gender confirmation surgery). These are very convenient children to advocate for, since, unlike real children (hungry children, children killed in the Gaza genocide, children whose parents have been kidnapped by ICE, children whom Matt Goetz and Donald Trump trafficked for sex, children in cages at the US border, trans kids driven to self-harm and suicide after being denied care), nonexistent children don't want anything from you and they never make public pronouncements about whether you have their best interests at heart."

Richtmyer-Meshkov Instability

If you send a shock wave through a magnetized plasma–something that happens in both supernova explosions and inertial confinement fusion–it can trigger an instability known as the Richtmyer-Meshkov instability. The image above shows a form of this, taken from a simulation. Rather than treating the plasma as a single idealized fluid, the researchers represented it as two fluids: an ion fluid and an electron fluid. This allowed them to better capture what happens when certain components of the plasma react to changes faster than others do.

The image itself shows the electron number density across the fluid, where darker colors represent higher electron number density. The interface between high and low-densities shows a roll-up instability that resembles the Kelvin-Helmholtz instability, but there are also regions of mushroom-like plumes that more closely resemble Rayleigh-Taylor instabilities.

The authors note that these structures don’t appear in simulations that represent a plasma as a single fluid; you need the two-fluid representation to see them. (Image and research credit: O. Thompson et al.)

Really pleased to publish this article.
