This article suggests the possibility of training AI on pre-existing proposals and their review reports, scores and related decisions. I.e. training them on a system which is known to preferentially award larger amounts of money to white men. What could possibly go wrong?
UKRI exploring use of AI in grant review - this will prompt debate but interested to know if people think it’d encourage novelty or the opposite? www.chemistryworld.com/news/ukri-op...

The ejection velocities of interstellar objects signpost their progenitor system architectures
Interstellar objects (ISOs) ejected from planetary systems carry kinematic signatures of their formation environments. The properties of these velocity distributions govern the ISOs' propagation and d...

Samples of Bennu, a primitive asteroid orbiting near Earth, contain some surprising ingredients: natural sugars, gummy polymers, and specks of stardust that are even older than our solar system.
There's a lot of complex chemistry brewing in space! 🧪🔭

When you're dealing with a precious sample of an asteroid, you want to make use of every bit. Here you can see scientists harvesting a miniature chunk of Bennu for analysis. The piece they are moving is just 30 microns (1/1000th of an inch) wide! 🧪🔭

We are now truly entering the declining phase of the solar cycle, but we’re far from over! Although solar flares are less common during this phase, some of the strongest flares of the solar cycle typically occur during this declining period.

Did some research related teaching stuff today. Trying to figure out to pull down a cutout of an asteroid imaged by Rubin Observatory, had 2 meetings with grad students, and dealt with other admin. I also attended the School’s (wider department) gender minority coffee hour that I helped organize.

It takes 225 million years or so for the Solar System to make one orbit around the galaxy. Sharks evolved long enough ago that they’ve done it twice.
