A friend just asked me what I do to stay hopeful and I told him one of my favorite strategies…I stay hopeful by remembering that no one has any idea what the fuck is going to happen, so as long as we don’t know, we gotta do what we can.

National Climate Assessment Authors Are Dismissed by Trump Administration
The Trump administration told researchers it was “releasing” them from their roles. It puts the future of the assessment, which is required by Congress, in doubt.

CGP Grey has taken "thumbnail optimization" very literally by applying common deep learning augmentation techniques to his older videos' thumbnails: color inversion, tile flipping, gaussian noise... It's certainly working, I myself absentmindedly clicked on one.

there's a lot of things going on in the world right now (from asteroids to... more existential threats), but we're working really hard on getting some papers out ASAP just in case, and our FRC team is building a kick-ass robot, so I just have to keep going.

Apparently all the PhD researchers holding prestigious NSF-funded research fellowships are having their salaries withheld until some unspecified time when the leadership figures out how to eliminate any grant funding that doesn’t align with the president’s political ideology.
It’s official: all funding requests made on Tuesday by postdocs for their salaries have been unilaterally rejected by NSF.

LAUNCH at 0703 UTC Jan 16 of New Glenn from Canaveral,
with successful parking orbit insertion of stage 2. Stage 1 made its reentry burn but did not successfully complete landing on the barge. Stage 2 is due to restart to go to higher orbit. Congrats Blue Origin!
