wtf this guy just had Claude Sonnet 5 perform brain surgery on a living mouse the goal was to treat the mouse's epilepsy so it would stop having so many seizures. here's what Claude did: > it looked at 19 possible treatments and picked one that boosts the brain's natural calming chemical > it chose where to inject it based on where these seizures are thought to start > it worked out the exact injection point by averaging three research papers > it lowered the needle 4.3 millimeters into the mouse's brain > it injected a 20,000th of a teaspoon of the treatment over five minutes > it checked the live camera 32 times to watch for things like bleeding and the mouse woke up and recovered well! interestingly, Opus 5.5 and Opus 5 both refused the task because it involved real biology so Sonnet 5 got the job. and as far as the researcher knows it's the first time an AI has picked a treatment and then injected it into the brain of a living mammal.
Last night an AI agent performed brain surgery on a mouse. We gave it 19 gene therapy vectors in a spreadsheet, a mouse model of epilepsy, access to a motorize surgery rig with cameras and one goal: reduce seizures. It picked the drug. It picked the brain region. It derived the coordinates from three papers. Then it drove the stereotaxic arms into the brain and injected 250 nanolitres while watching the entry site through the rig camera for bleeding. A licensed vet gated every irreversible step and held a physical kill switch to stop the AI agent. Thread on what it decided, what it saw, and the moment it refused to let me override it. [Writing this on the spot out of excitement, but I've been 18hrs in front of my laptop coding and coordinating this, so keeping it brief and descriptive, more cohesive thoughts on this soon...]

this could've jus' been a checkbox, but they added a slider with a little friction at either end that reflects the physical behavior tiny details, thoughtfully considered
this progressive blur effect interaction for the new iphone over on apple's site is pretty neat

Big Almond has been doing this the whole time and we’ve been out here worried about data centers. Unbelievable.

For anyone who hasn’t made the switch yet, the @ReadwiseReader read-it-later app is *phenomenal.* The absolute best in the business and you should be using it!!
Wow! Saddened to hear that @Pocket (the biggest read-it-later app) is shutting down on July 8th. You can import all of your pocket articles, highlights, etc into @ReadwiseReader with two clicks

So many have commented on my last post about people not having an inner monologue saying they have “aphantasia” or “mind blindness”. 🤯 Here is a simple test I found. Close your eyes and picture a red star. How well can you see the star visually on a scale of 1 to 6?
