Where U.S. science has been hit hardest after Trump’s first year The Trump administration has slashed the number of grants from the National Institutes of Health, with far fewer focused on women, cancer and mental health.

Those of us doing research related to women’s health have been hit particularly hard by the govt’s sabotage of the NIH. I spoke to WaPo for this piece, as painful as it was to discuss the reality my lab is facing. www.washingtonpost.com/science/2026...

The Lippi lab is hiring a postdoctoral associate! We built new technologies to study post-transcriptional regulation in the healthy and diseased brain. We are recruiting motivated and talented scientists who will use these tools to discover new biology and new therapies.

Entorhinal cortex represents task-relevant remote locations independently of CA1 - Nature Neuroscience Neurons in medial entorhinal cortex collectively represent discrete nonlocal positions during immobility. During this nonlocal coding, CA1 is uncoupled from entorhinal cortex. These representations ar...

My main postdoc work is now published: www.nature.com/articles/s41...! We (myself, Isabel Low, Frances Cho, and @lgiocomo.bsky.social) discovered task-relevant remote representations in entorhinal cortex independent of CA1. #paperthread below! 1/13

As a survivor (barely) of conversion therapy....I feel like crawling under my desk and crying. All the more reason to support organizations for homeless LGBTQIA+ youth, the Trevor Project, etc., with your $$$ and time and whatever you can give.

Snappy looking calcium imaging videos – Labrigger

Hey everyone! 
Do you remember this post from your fav blogger? labrigger.com/blog/2025/11...


Not super easy to use - I know. Well, spring break has sprung here at ucsb and we decided to bring that activation energy down a notch.
 I guess welcome to my first bsky thread? letsgo (1/5)

Writing out a conversation I’ve been having a lot at this conference:

Things in US science are far, far worse than people know.

Far worse than even other scientists know.

New paper is out! Analog neural networks have the potential for highly efficient computation at the edge, but show decreasing accuracy with sources of noise. We show that biologically motivated “context” enables recurrent neural networks to adaptively change their dynamics to mitigate these effects.
