In a couple of weeks, every senator and representative will vote on whether to empower Trump to send more secret police forces into our communities.
This means it’s extra important for Congress to hear from you right now.
Demand that your senators use their power to rein in ICE. #ICEOutForGood

“Hidden corruption persists because it is difficult to mobilize against. Exposed corruption shifts the axis of politics from left versus right to clean versus corrupt, people versus oligarchs. That’s a fight authoritarians lose.”

Several people I know have used the word "beautiful" for this piece, and that's exactly right. A beautifully phrased essay on the bind we're in— until we aren't.
Recommended, in an extreme way.

We love our Haikubox! Our data contributes to crowdsourcing bird song patterns as the birds migrate!
It’s wonderful to know all the birds we are hearing in our garden. Yesterday it recorded 39 species and 2,685 calls and songs.

Using sound to see... Watch Black-and-white Warblers migrate north in spring and south in fall in this video created with 2025 #bioacoustic data from Haikuboxes. When a Haikubox identifies a bird using sound, the data can plug into community science.

Stood on the corner of a busy intersection in Colma this afternoon, with a bunch of other people who are demanding #ICEOutForGood & mourning Renee Good & all the other people ICE has killed. Many horn honks from cars in support.
It’s up to us to refuse murder as normal, which does not seem hard.

If you are in or near San Francisco, there is an emergency protest at 6 pm on Sansome, at immigration court. It is safe, I’ve been there multiple times, but large numbers of people would be very helpful. It’s time for us to get in the streets. Please turn out wherever you are, if you can.
ICE JUST MURDERED A WOMAN IN MINNEAPOLIS
Emergency protest TONIGHT! 6 PM 630 Sansome, SF
This is a non-violent, peaceful protest organized by ISF, endorsed by Bay Resistance & Mujeres Unidas. Come join us, resist ICE:

A miserable disgrace. I am so ashamed of our country. We let him get away with this, and then put him back in the White House. We have failed at our most basic responsibility. It’s sickening.
The newspaper headlines. It's insane that he got away with this unpunished.

Seems like a really good reason to avoid getting COVID-19, flu, and any other viral infections that can be prevented via vaccination (and masking).
Blood biomarkers in a middle-aged population suggest that SARS-CoV-2 infection is associated with greater brain β-amyloid plaque accumulation. The findings published in Nature Medicine in January suggest that SARS-CoV-2 may increase the risk of future Alzheimer’s disease. #Medsky 🧪
