Radiation’s Effect on Astronauts | On Wisconsin UW research helps clear the way for travel to Mars.

How will radiation affect astronauts who travel to Mars? UW–Madison researchers are exploring that question — and their work could also provide insights on improving radiation treatment for cancer patients here on Earth.

I always say: only automate what you're ok letting atrophy

"Thinking time —the time needed to concentrate without interruptions has always been central to scholarly work. It is essential to designing experiments, compiling data, assessing results, reviewing literature and, of course, writing. Yet, [it] is often undervalued."

“Science is a smart, low cost investment. The costs of not investing in it are higher than the risk of doing so… talk to people about science.” - @kevinochsner.bsky.social makes his case to the field #sans2025

Kick off #FusionEnergyWeek with an intro to the science that could transform our energy future. Join Troy Carter at ORNL for a talk exploring the fundamentals of fusion energy and East Tennessee’s growing role.

I am very happy to share our latest work on the information theory of generative diffusion:

"Entropic Time Schedulers for Generative Diffusion Models"

We find that the conditional entropy offers a natural data-dependent notion of time during generation

Exclusive: NSF stops awarding new grants and funding existing ones US science funder also plans to screen grant applications for compliance with ‘agency priorities’.

BREAKING: NSF has frozen all grant funding, as of yesterday. It's unclear when they will resume funding awards, or why the pause has been put in place. www.nature.com/articles/d41...

I'm going to state something that's obvious at every university: today was the deadline for folks to decide which grad school they'll join in the fall.

This probably won't make headlines, but because we don't expect normal funding, universities aren't admitting a normal number of students.

Volume estimates for unions of convex sets, and the Kakeya set conjecture in three dimensions We study sets of $δ$ tubes in $\mathbb{R}^3$, with the property that not too many tubes can be contained inside a common convex set $V$. We show that the union of tubes from such a set must have almos...
