Same task, different strategy ↔️
Why do identical neural network models develop separate internal approaches to solve the same problem?
@annhuang42.bsky.social explores the factors driving variability in task-trained networks in our latest @kempnerinstitute.bsky.social Deeper Learning blog.
I recently spoke at Morehouse School of Medicine's Curtis L. Parker Student Research Symposium and came away inspired & uplifted by the incredible work these students & postdocs are doing ⚕️
To all the talented trainees at Morehouse: keep up the great work. You will make a tremendous impact!
Finding one mutation that improves a protein is hard. Finding five that work together is exponentially harder.
Today in @science.org, Hsu and Konermann labs present MULTI-evolve, a lab-in-the-loop framework that does it in just one machine learning-guided round.
A reminder that applications close Friday, Feb 27 for the Arc AIxBio Fellows Program.
Undergrads: propose and run your own AI + biology research project over 6–12 months, with mentorship from Arc scientists. Apply solo or as a team of 2–3.

Most drug discovery starts with a disease & searches for a cure. New research out in Cell from Arc investigator Isha Jain’s lab flips this model, starting with a potential cure (vitamins) & systematically identifying which diseases it could treat.

Thanks to Ladan Jiracek for having me on the Neural Implant Podcast!
We discussed how clinical neuroscience is combining high-resolution brain recordings with sophisticated behavioral studies to provide a truly comprehensive characterization of the human brain.

Pssst… it’s been a few years but @stellatecomms.bsky.social will be hiring for TWO roles ✨
Looking for excellent communicators with advanced degrees. Must have a strong attention to detail, passion for science & enjoy working within a team. Agency & media experience is +++ but not required.
In human teeth, stressful periods can actually cause irreversible changes in the enamel.
We don't know if the same is true in snails, but it's still fascinating to see the similarities.

It's always rewarding to connect with trainees at events like #Sfn25 & #NER2025.
In these conversations, more and more students are asking how to break into Neurotech—fortunately for them, the community is stepping up with great resources to help them navigate their paths 🧵1/4
This conversation between @davideagleman.bsky.social & Sergey Stavisky––two influential voices in the field––is a great primer on where #BCI is headed and what breakthroughs can mean for patients.
Well worth a listen for anyone following the future of Neurotech👇🏽

New paper for #neurips2025!
AI models adjust millions of internal settings to get better at a task. But how are these adjustments determined? For decades, we've mostly figured this out through trial & error.
We took a different approach...🧵 (1/6)

Wow, such an insightful and substantive open floor discussion at last night's Memory Hub meeting! 🤓
Do we need ANY of the same synapses that were active during learning to be reactivated to recall a memory? Lines have been drawn and sides taken!
No one can ever accuse Dr. Helen Mayberg @sinaibrain.bsky.social of being a chicken 🐔 🐓
From her cutting edge work in DBS for anhedonic depression to her bold fashion choices, she is the definition of avant garde #FashionsOfACNP #ACNP2026 @acnporg.bsky.social
I edited a special issue of Addiction Neuroscience on dopamine circuitry & heterogeneity in addiction - now complete!🧠🧪
Check out the full issue & my editorial (all open access) here: www.sciencedirect.com/special-issu...
The title of the article "Does Cannabis Actually Have Medical Benefits?" underneath which is an image of a cannabis leaf with a stethoscope wrapped around it.
#Cannabis should not be treated like a medical panacea. Like any other treatment, we need strong evidence of its safety & efficacy before confidently supporting its use for medical conditions.
A recent review from Dr. Kevin Hill highlights the knowledge gaps we still need to fill: bit.ly/3Ksrui6
Reclassifying #cannabis could expand research to understand its possible clinical use. At the same time, it’s important to remain thoughtful about potential addiction & mental health risks, particularly for adolescents & young adults.

Screenshot of the top of the article, including the article title, authors, and abstract.
Identifying the neural pathways that link drug cues to relapse is critical to improving substance use disorder treatments.
New work from my lab found that #CBD reduces cue-driven heroin seeking in rats, related to changes in gene expression 🧠👇

Many of today's youth are under the misconception that #cannabis is not addictive, but the truth is, it can be.
I spoke with Impact Parents about empowering youth to understand the effects of cannabis use on their brains and health 🧠 ⬇️ www.youtube.com/watch?v=-wZu...
Arc’s Science Fellows program gives a springboard to recent PhD and/or MD students to become a PI right out of grad school.
Interested? Apply by Jan 12 or hear from our team and current Fellows Jingtian Zhou, Uche Medoh, and @mayaarce.bsky.social in this video: youtu.be/3Qs5cmXxsWQ
Predicting cell state in previously unseen conditions has typically required retraining for each new biological context. Today, Arc is releasing Stack, a foundation model that learns to simulate cell state under novel conditions directly at inference time, no fine-tuning required.

The next inflection point in virtual cell modeling will require large-scale perturbative data. To get there we are partnering with @tahoetherapeutics.bsky.social and @biohub.org
to help us generate a dataset to push us forward: arcinstitute.org/news/tahoe-a...
What happens when a neuroscientist realizes trauma rewired their own brain? ❤️🩹
