Masa's paper is out in Hippocampus. The left-right alternation of hippocampal theta sequences at T-maze choice points, much loved as a 'planning' signal, falls straight out of MEC dynamics. Well done @masahironakano.bsky.social, fun project with @clopathlab.bsky.social doi.org/10.1002/hipo.70131

Admirable clarity @science.org
The Trump administration hates academic science funding, full stop. They hate where that money goes, and they hate who it goes to. They want to keep all that money for themselves, to hand out to favored cronies who can help them get elected and to steer yet more money and more power back into their hands.

That’s it. That’s the story

YES! If I have one piece of advice for students/early career people, it is to use and learn the free/open source software inside out, even if your institution has licenses for the commercial equivalents. There will be a future time where you will lose access to the license, and they are *expensive*!
