Chemists eyes no longer need spectacles!!!
SDLs raise some new safety questions - here we introduce Chemist Eye, a distributed safety monitoring system designed to enhance situational awareness in SDLs. 👏 for Francisco Munguia-Galeano, who tested it for accident recognition by lying repeatedly on the lab floor. www.arxiv.org/pdf/2508.05148

"PhD level expert ..." Well everyone had to start from somewhere before getting their PhD. I am not sure anyone with a PhD in Chemistry started from there though
It still can't electron push - here are some of it's attempts at peracid epoxidation.

The text description of the mechanism is not bad, but not perfect. Seems unable to connect that to images

I have started using uv for my python projects. It's the best thing ever. Handles conflicts better that conda, dead fast, interoperable. It's amazing!
