A welcome, if belated, awakening to the disconnect between Musk's actions and the stated values of the Royal Society?
Mini-scoop: After resisting pressure to strip Elon Musk of his fellowship for months, the Royal Society is meeting on 1 October to discuss his removal – following his decision to address Tommy Robinson's far-right rally on Saturday.

Must admit I'm a bit sad that the Royal Society consider their fellows to be "mid career". Kudos to these amazing people, but what hope for the rest of us in obtaining these "mid career" fellowships..

So there has been a lot of back and forth about this. I think there are two potential issues here: 1. The increased bureaucratization of HE, and 2. Senior management led "initiatives".
Why academia is sleepwalking into self-destruction. My editorial @brain1878.bsky.social If you agree with the sentiments please repost. It's important for all our sakes to stop the madness

Dr. Don Turcotte passed away yesterday. He was 92 years old.
he was surrounded by family. His granddaughter had wanted to read something to Don in the hospital so his son suggested “Geodynamics” - she was reading to him in his final moments. ⚒️
