Optogenetics has ignited a revolution in neuroscience. Although this decree may sound like hype, researchers in the field disagree, saying the technique is allowing them to understand brain function and disorder with unprecedented precision. #NobelPrize #chemsky 🧪

Tellingly, our president only instigated a review after the news was all over the major national outlets, not when student journalists first broke the story. Small surprise, as the two have been speaking on AI with one voice and helping make travesty of education jointly

The college at which I teach, Dartmouth, rose from 200-something to #6 for free speech in FIRE’s rankings. I believe this is misleading. This feels to me & many colleagues like the most restrictive atmosphere we can recall. & many students tell me confidentially they censor themselves about AI.
