Scientists demonstrate superior cognitive benefits of outdoor vs indoor physical activity
A new study suggests that where kids exercise matters: children who played basketball outside showed sharper thinking and faster reaction times than when playing indoors, hinting at a powerful brain-boosting synergy between physical activity and nature.

Excited to share this project specifying a research direction I think will be particularly fruitful for theory-driven cognitive science that aims to explain natural behavior!

We're calling this direction "Naturalistic Computational Cognitive Science"

Different anesthetics, same result: unconsciousness by shifting brainwave phase
MIT study finds that an easily measurable brain wave shift may be a universal marker of unconsciousness under anesthesia

We identify a computational basis for how persistent underconfidence is maintained in the face of intact performance, finding that it is grounded in impaired updating of global self-beliefs from local metacognition

Terrific how-to on communicating the value of basic research to the public in @thetransmitter.bsky.social by @tonyzador.bsky.social.

You may be curious. But when you are communicating the value of what you do, it’s not about you. Point to discoveries.

Every scientist, long before they were a scientist, was a little kid who stood in front of a fish tank or stared up at the stars or turned over a rock to look at the bugs underneath and said “wow”. On the best days, working in science still feels like that.
