Full survey results show American public have high levels of confidence in scientists while revealing some partisan differences (including on how to fund science), but statements asserting lost trust should be read instead as intentional efforts to degrade trust.

NIH funding underlies all of these advances--support fundamental science, and the bridge from there to the clinic 🧪
For the first time, the five-year survival rate for all cancers has reached 70 percent, according to a new report, a trend that reflects the effectiveness of early prevention and detection strategies, and advancements in treatment and care, experts say. https://wapo.st/45T6Zm3

Can humans & animals really use internal maps to take shortcuts?
Tolman famously said yes - based largely on his Sunburst maze.
Our new review & meta-analysis suggests evidence is far weaker than you might think.

Tolman's Sunburst Maze 80 Years on: A Meta‐Analysis Reveals Poor Replicability and Little Evidence for Shortcutting
In 1946, Tolman et al. reported that rats could take a novel shortcut to a goal after training on an indirect route, supporting the Cognitive Map theory. However, a review of subsequent Sunburst maze...

🧠 New year, new preprint!
Why does motor learning involve multiple brain regions? We propose that the cortico-cerebellar system learns a "map" of actions where similar movements are nearby, while basal ganglia do RL in this simplified space.

Developed at our Janelia Research Campus, iGluSnFR3 is a fluorescent sensor designed to rapidly detect & image glutamate — our brains' main chemical messenger — allowing researchers to observe (dazzling) neural communication as it happens. 🎆

How basic neuroscience has paved the path to new drugs
A growing list of medications—such as zuranolone for postpartum depression, suzetrigine for pain, and the gepants class of migraine medicines—exist because of insights from basic research.
