Douthat On AI
Ross Douthat: "An Age of Extinction Is Coming. Here's How to Survive."
I think he's too pessimistic. But his essay does make some good points.

Missing Matter
"A new analysis of the sky has finally confirmed where the missing half of the Universe's visible matter has been hiding." (Via H.R.)
My first guess was under the couch.

Human Vs. AI Reading Medical Notes
This question was posed recently on social media -- basically, asking someone to interpret a near-indecipherable orthopedic clinic note.
My own translation:
Ortho
===========
R(ight) knee pain
R(ight) knee: + effusion, +pain, decreased ROM (range of motion)
Xray right knee: moderate OA (osteoarthritis)
A/P (assessment/plan): Right knee osteoarthritis
Right knee injection
F/u (followup) 3 months.
I also asked Grok AI to attempt to translate the image, and I have to confess it did surprisingly well!
Wave Confinement
"Thought To Be Impossible: Scientists Break Century-Old Physics Barrier". (Via H.R.)
A research team from POSTECH (Pohang University of Science and Technology) and Jeonbuk National University has achieved a groundbreaking feat: the complete confinement of mechanical waves within a single resonator—something long considered theoretically impossible. Their study, published on April 3 in Physical Review Letters, represents a significant advance in solving the century-old puzzle of bound states in the continuum (BIC).
