"Use it or lose it." This is great advice for exercise, but when cells need to slow down or go dormant, they need to store ribosomes to recover growth in the future. They use hibernation factors to do this. Here is our latest story on how archaea hibernate ribosomes (1/7):

Is the government ever going to release the name of the masked agent who killed Alex Pretti or are we going to continue to have a federal secret police in this country?

TikTok is under right wing billionaire control now. Plan your exit strategy.
This morning, I recorded a video on TikTok about why DHS’s arguments for the power to enter homes without judicial warrants in immigration cases are bunk.
Nine hours later, TikTok still says my video is “under review,” and can’t be shared.
Well, here’s a link:

My sister-in-law's dad died last week, in hospice in the VA hospital in Minneapolis. I just learned Alex Pretti was part of his care team. They shot Alex less than 1/2 mile from my niece's house while doing the same observation work that my niece is doing. These are real people. Step up folks!

The majority of organizing happening in Minnesota isn’t just peaceful, it’s INVISIBLE. Moms showing up who won’t be interviewed on TV, people whose ICE patrols don’t turn into viral video. The grocery runs, the donations, the people filming bc they happen to be there. Please remember this.

We have to see the logic of the killings as well as the killings themselves. The horror is a truth in itself. But it is also a sign of a political logic, one known from the totalitarian regimes of the twentieth century.

Bill Kristol sees this shit clearly. I don't know how so many elected Democrats don't.
Also, may I say that I don’t agree with people saying ICE and CBP need “more training.” They’re doing exactly what this administration has trained them to—impose a reign of fear in blue cities. They don’t need more training. They need to be ripped up root and branch.

Nonviolence is, in fact, working. This administration is weaker than it was a year ago. More and more of the public is becoming galvanized against it; its agents are being impeded.
Do you honestly think people in the civil rights movement and other nonviolent movements faced no violence themselves? They practiced nonviolence because it works, because the oppressor wants a shooting war, which is the war it will win
How's your non-violent working Mr Gandhi stancil? They will kill each and everyone of you right if they had the chance and you will still be writing Kumbaya.
