Starting in Spring or Summer 2027 K99/R00 (under its new activity code KT1/R00) will only be available to US citizens, permanent residents, and non-citizen nationals. I am hearing this from many program officers, but NIH has yet to make an official statement to my knowledge.

Join us for Brain Chats this Saturday! Dr. Clay will present, "An Introduction to the UAB Alzheimer's Disease Research Center: The Importance of Brain Aging Research." Come learn why brain aging research matters and how you can help advance Alzheimer's research! Free & open to all! 🧠📚

Very excited about this new preprint from @odrake.bsky.social, an incredibly talented MD/PhD student in the lab. 🧵 below, but the TL;DR: we found a rare striatal neuron subtype with unique transcriptional, spatial, and circuit properties that gates opioid reward.

Our new preprint from @daylab.bsky.social characterizes Chst9-MSNs, a specialized NAc population with high Oprm1 expression and opioid sensitivity that is required for fentanyl reward learning. Excited to share this work! 🧠🧬 www.biorxiv.org/content/10.6...

“Seven days after the girl’s medical team infused trillions of viruses carrying the recipe for the base editor into her spinal fluid, she died of a severe immune reaction linked to the therapy…” This, in @science.org, is an important and tragic story. (It’s also an incredibly well reported one.) 🧪

Exclusive: Death of girl in Chinese gene-editing trial was never made public

I love this photo from Simon: the finches are perched on a thorny tree that evokes the basal ganglia medium spiny neurons we identify as the postsynaptic locus of learning. Full paper thread 👇

Where, exactly, does learning happen in the brain? Out today in @nature.com, we identify a synaptic locus of birdsong learning and show that the circuit can be tuned to make birds learn faster - but at a cost. Read on👇 #neuroskyence 🧪 #prattle 💬 #bioacoustics Shareable link: rdcu.be/fiyrS

Dopamine and sodium appetite! Sodium appetite causes a 'sign change' in the taste of hypertonic NaCl solutions. We've previously shown that generation of the appetite recruits phasic dopamine to the taste of NaCl; here we show the 'derecruitment' process during satiation.

Rapidly decreasing phasic dopamine responses precede a hedonic switch during satiation of sodium appetite https://www.biorxiv.org/content/10.64898/2026.07.16.738888v1

Notice of Award Monday! Grateful to NIDA for supporting some very exciting work defining the cellular and circuit mechanisms that opioids target to produce rewarding effects.

Excited to share this new Addiction Neuroscience Special Issue on Transcriptomics in Addiction. Edited by Laura Saba and Dayne Mayfield with articles from Ana-Clara Bobadilla, Ryan Logan, Giordano de Guglielmo, José Sotelo-Silveira, and Tamara Phillips labs. www.sciencedirect.com/special-issu...

Addiction Neuroscience | The Role of Transcriptomics in Addiction | ScienceDirect.com by Elsevier

The generation of RNA transcripts in a cell is one of the first opportunities for interaction between DNA sequence and the environment (both at the organism and cellular level). Although many RNA transcripts get translated into proteins that are active in the cell, many other types of transcripts play critical roles in both the transcription and translation processes and ultimately, in how our bodies respond to our environment. Brain transcriptomics has the potential to mediate our acute responses to drugs of abuse and to reflect the changing cellular environment across the addiction cycle. Furthermore, RNA-based therapeutics are emerging as a significant treatment resource for many diseases. However, our knowledge about non-coding RNA transcripts, differences in transcript processing, and the interdependence among networks of transcripts is far from complete. This Special Issue features novel research into the role of transcriptomics and epigenetics in the neuroscience of addiction including predisposing factors and changing molecular phenotypes across the addiction cycle with the ultimate goal of identifying novel treatment and prevention approaches.

Very cool original artwork by lab MD/PhD student Olivia Drake for Caroline Fiore’s successful master’s thesis defense in the lab. Congratulations Caroline! Much more to come soon on some really important findings that Caroline contributed to.
