We watch ATP, the energy currency, in tiny compartments of brain synapses to show that synapses talk to their local mitochondria to produce energy right when needed during plasticity, required for memory formation: www.biorxiv.org/content/10.1...

@jeremymberg.bsky.social is a national hero. Too many of my tenured colleagues are hiding in their offices, hoping the storm will pass over them if they keep their head down. I'm immensely grateful that Dr. Berg has the opposite response to this moment.
I am not going to call this a Bluetorial, because I do not want to sully that term (which, at least I, find joyful).
Let’s call it a Orwellial.
