This country is not those two. They were radicalised extremists. That’s the point. Extremism is by its nature rare. It does not grow from a failure of moral consensus. It seeks to shock the consensus that exists. Those suggesting otherwise for their own advantage betray the memory of this tragedy.

Steve isn’t here anymore, but he always posted this picture on Hanukkah so I thought we could carry on his tradition and remember him.
Happy Hanukkah to our friends who celebrate. Rachel Posner, a rabbi’s wife in Kiel, Germany, took this photograph in 1931 -- a potent reminder that fascism must be fought in every generation, even if it's wrapped in an American flag and a red hat.

The thing about measles is that it’s the only known virus that triggers immune amnesia - it causes your immune system to forget everything it has previously learned. Meaning you essentially reset to zero and are now at risk of basically everything.
It can take 2-3 years to get immunities back.

Mind-blowing new paper just out! 🧪
A research team used #Gaia to create the most detailed 3D census to date of OB associations within ~1000 ly from the Sun.
Result? 🔭
57 groups of massive stars — twice as many as we knew before — that were born together and are now slowly drifting apart.

A new census of OB associations with Gaia!
In this study, we took advantage of my OB stars map to find new OB associations within 1 kpc. The goal was to create a useful reference catalogue for this era, and to trace the star formation and structure of the local Milky Way.

Built upon ≥70 Mastodon instances, then bridged to BlueSky using @ap.brid.gy, it feels like a social-media reinvention of the Portal 🇷🇺Kombat concept.

2nd Nov. 2025 marks the 25th anniversary of the ongoing human presence off-world.
That is, humans have continuously occupied the ISS for exactly 25 years today.
So if you're <= 24 years old, you've never lived in a world where humans were *only* terrestrial-based.

this is a very cool story but also part of a wider and incredible resurgence of the Eurasian beaver, which dropped to approximately 1,200 survivors in the early 20th century and is now up to 1.5 million. Beavers were reintroduced to the UK this March.
imagine if a family of beavers randomly showed up right now and finished whatever thing you've been putting off
