@kravitzlab.com 😭😭 this is the active port, luckily there is evidence of pellets having been dispensed overnight. The inactive port was clear of bedding.
🚨New paper alert! 🚨 Inactivation of the nucleus reuniens causes relapse of extinguished fear. Here we show this “circuit-induced relapse” depends on hippocampal fear memories and is mediated by hippocampal engrams. Congrats to the team!

Happy to share that our work "Amyloid-β induces lipid droplet-mediated microglial dysfunction via the enzyme DGAT2 in Alzheimer’s disease" is out now @cp-immunity.bsky.social! ➡️ www.cell.com/immunity/ful...
Amyloid-β induces lipid droplet-mediated microglial dysfunction via the enzyme DGAT2 in Alzheimer’s disease
Why microglia stop reducing amyloid deposits from Alzheimer’s disease (AD) brains is unknown. Prakash, Manchanda, et al. show that microglia increase their lipid droplets and lose their phagocytic cap...

I wrote a piece for @thetransmitter.bsky.social www.thetransmitter.org/sex-differen... With the fate of NIH-funded research uncertain, it is extra important that the work we do now is most likely to benefit everyone. Adhering to SABV in the lab and in grant & paper review is the right thing to do.
Amid NIH upheaval, how to keep sex as a biological variable
Even in the absence of formal instruction to do so, we should continue to hold our colleagues accountable for SABV practices.

New review from the lab! Do #microglia metabolize #fructose in #Alzheimers Disease? rdcu.be/edIRM Big congrats to the first author @AnnaliseSturno for all her hard work 💪🏻👩🏻🔬💪🏻
More than ever we need to talk about the importance of our "basic research" in public and political forums. Kudos to #AnnaliseSturno and @neurohassell.bsky.social for getting out there and sharing their work on fructose metabolism and Alzheimers Disease at #Denver #Capitol
Today’s STEM Day at the capital was a success! My students worked so hard on making posters that were accessible and highlighted all the important work we are doing! @projbridgeco.bsky.social @cuanschutz.bsky.social
@lindseyforco.bsky.social & @shannonbird4co.bsky.social I live in y'alls district and will be talking about the link between sugar on the 🧠 and Alzheimer's in @drkimberleybruce.bsky.social 's lab at @cuanschutz.bsky.social with @projbridgeco.bsky.social. Hope to see y'all there!
I continue to be blown away by the sub-cellular resolution that our new #Nanolive 3D explorer allows. Look at these #microglia go!

A Black woman named Aliyah was struggling to find work. So, she catfished herself and made a fake profile on LinkedIn named "Emily." Emily had the same qualifications as Aliyah but received 57.9% of interview invites while Aliyah received 8.9% This is what we mean when we say racism is systemic.
I think I finally got the hang of surface mount resistors. Version 7.1 is a different piecing together project for sure.

🌟 Cai Lab Nature (@natureportfolio.bsky.social) paper alert! In work led by Joe Zaki, we find that rest periods after learning not only stabilize new memories BUT ALSO integrate new memories with older ones from days past! (1/10) Read it here: www.nature.com/articles/s41...
#CUAnschutz researchers are among the first to recognize how Herpes simplex virus type 1 infiltrates the brain, leading to a better understanding of how it may trigger neurological diseases. The study was recently published in the Journal of Virology. ⬇️🧠

A quick note to all the NewSkys: there really isn’t algorithm here. We depend on each other to spread the word. So if you want others to see something, repost it. Liking something adds it to your feed but doesn’t surface it for others.
