Congrats to Kim Reinhold, soon to launch her own group in the Eaton Peabody Labs, on this labor of love. Basically, she shows that the visually recipient zone of the striatum mediates outcome-dependent trial to trial updates of behavior. nature.com/articles/s41586-0…

The latest work from the Lammel lab is out today in @Nature! Discover how changes in neurotensin signaling from the NAc Lat to the VTA lead to food devaluation in a mouse model of obesity 🧀🐭 nature.com/articles/s41586-0…

Proud to have contributed to @JiaxuanQi's masterpiece out @Nature! She shows dopamine transients track the quality of song during juvenile song learning and that dopamine release is driven not just by VTA firing, but by a local cholinergic mechanism! nature.com/articles/s41586-0…

How much analgesia is needed to manage pain levels in mice after brain surgeries? A single dose of meloxicam seems to be enough. Even the addition of opioids cannot provide a clear benefit (in line with recent work from others, see refs in our preprint): biorxiv.org/content/10.1101/…

Science Matters. 🧪🔬🚀 I am alive because of science. We all benefit from science — every day. Science is in our homes, our hospitals, our streets, our work. For 80 years, science and technology have been a north star for the United States. In 1945, Vannevar Bush’s report to the president of the United States Science, The Endless Frontier called for bold government support of scientific research to drive national security, economic growth, and innovation. This vision led to the creation of the National Science Foundation and to policies ensuring the U.S. leads in science & technology. Since then, for 80 years, the government has invested in science, fueling discoveries that transformed our health, economy, and quality of life. Science is not a zero-sum game—it creates knowledge, exponential value, innovative industry, and longer better lives. From life-saving medicine, advanced diagnostics, and disease prevention to AI-driven innovation, space and deep-sea exploration, clean energy, next-generation materials, quantum computing, and precision agriculture, science continues to shape our future. Science matters. 🔬🌍💡 #ScienceMatters #EndlessFrontier #FutureOfScience

NIH Brain Initiative funded multiple studies on closed loop brain stimulation for a number of neuro/pscyh conditions including Parkinson Disease. Now FDA approval granted for device that adjusts stimulation based on a person's neural activity. medpagetoday.com/neurology/p…

Major breakthrough in pancreatic cancer . Funded of course by the @NIH

Huge cancer breakthrough! mRNA vaccine (similar to COVID vaccine tech) shows stunning results against pancreatic cancer! 75% of responsive patients STILL cancer-free at 3 yr, normally 80% recur. Could revolutionize treatment for one of deadliest cancers! Funded in part by @NIH

Our paper on MouseGoggles - an open-source mini VR headset for mice - just came out! Really excited about finally integrating eye-tracking into the headset. Nice working with you @hongyu_chang! nature.com/articles/s41592-0… github.com/sn-lab/MouseGoggl…
