My dad abhors any negative comments about immigrants. Asked him recently why he’s so strong on it: ‘Because we’re always happy to take the rich and clever ones. Which means it’s not about disliking immigrants. It’s about disliking the poor and vulnerable. And that’s a bad human instinct.’

Right now, academic freedom is under attack in the United States. Actually, "under attack" undersells it. "Existentially threatened" is better, along with "already lost in many places."

Come for the fascinating historical poetry about exploding stars, stay for the excellent technical footnote about what different communities are referring to when they talk about “type Iax” supernovae.

very cool new result led by Steve Schulze focused on SN2021yfj - the first of a new supernova subclass, Type Ien (“one - e - n”). This star lost its H, He, & C layers, and shows strong emission from the inner S + Si layers !! Check out his Science Friday interview about this science! 🧪🔭☄️
