This is not a resource problem, it’s a priority problem.
The world spent $2.7 trillion on defence.
Humanitarians are asking for just less than 1% of that to save 87 million lives in 2026.
Let's choose solidarity over indifference.

Have a great week, people guaranteeing end of homelessness in Finnish communities, @amnestyfinland.bsky.social.
As usual, Woody Guthrie had it right.
"Yes, as through this world I've wandered
I've seen lots of funny men;
Some will rob you with a six-gun,
And some with a fountain pen."
I got it both ways this time around.

Graduate programs, do not allow professors who sexually harass students to be mentoring again. You’re responsible for the abuses ignored in labs and offices.
Doing a PhD is - at heart - one long discussion with your mentor. The discussion changes over time - with unexpected turns and ups & downs - but through it all is a pair of people discussing a topic endlessly to make sense of it.
PhD students: choose someone you like to talk to!
