Tomorrow, many of us will gather in Union Square in NYC to rally for trans kids, their rights and access to gender-affirming care. Alongside fighting for trans rights and healthcare for all in our community.
With many other actions needing attention.

ICE observers in the Twin Cities are in need of dash cams to prevent further intimidation and frivolous claims.
Cams are $110, memory cards $35, and ship to us directly via this wish list: www.amazon.com/hz/wishlist/...
If you've been looking for a way to help, we'd sure appreciate it!

There's a lot of interesting conclusions, but the one I like most is this: well-funded professional archives increase science return multiplicatively. They support BOTH new discoveries using archival data shepherded through the decades AND use of brand new observations. (2/3)

You aren’t meant to be this disciplined, this self-sacrificing to survive. The environment is supposed to support good living. We can have that. You are not a failure. That is politics.

(GenX relevant only) I was walking through LAX and saw a man in outrageously tight black leather pants and boots, just standing and waiting, but with his nose in the air and absurdly correct posture, one knee slightly bent. As I passed, mesmerized, I realized “Michael Flatley, Lord of the Dance”.

It's a shame the word "chevelure" (originally meaning something like "a head of hair") didn't catch more on in Astronomy:
1791. Herschel, in Phil. Trans., LXXXI. 78. "A star of about the 9th magnitude, surrounded by a milky nebulosity, or chevelure, of about 3 minutes in diameter."

Love this plot of the infrared absorption of lots of different hydrocarbon molecules (and DMS). Titan measurements are used here as an exercise for interpretation of exoplanet measurements.
