✨Important update: 312 neuroscientists were surveyed, and they assigned substantial probability to long-term memories only depending on static brain structure preservable by modern brain preservation techniques (!!!) 1/11

'ChatGPT' and 'Gemini' are too many syllables for an AI's name; I prefer to use nicknames, Chat and Gem 💬💎

IMO mummies should stay preserved
Scientists turn yeast found in gut of ancient mummy into 'very good' sourdough bread - beer's next trib.al/mcPYdAp

Connecting @pavlok with my @openclaw bot to zap me ⚡️for missing ToDos is by far the most fun task 😉

I'll be giving a talk! Come see us :)
📢 Announcing the Brain Preservation Summit 2026 → September 19–20 · Salem, Oregon We’re bringing together people working across the technical, clinical, and philosophical dimensions of brain preservation. The format will be TED-style: 15-minute talks, 5 minutes of Q&A, and structured breaks designed for deeper conversations between sessions. Attendees will also have the opportunity to tour the Sparks Brain Preservation facility. Learn more and register here: sparksbrain.org/summit-2026.…

I saw @anderssandberg over the weekend. He's still the only person I know wearing his cryo tag outside his shirt, which I love 😄😊 Was a great talk!
"How does anti-pain feel?" @anderssandberg presenting a really fun and philosophically challenging question at @CIMCAI event including ideas of "panpanpsychism", reversible computation, Toffoli gates, whole brain emulation, block time,... Paper link & summary in quoted post

BREAKING: Google is planning to release 32 million mosquitoes across Florida and California. The company has asked the EPA for permission to proceed, with the public given until June 5 to respond. The mosquitoes are infected with Wolbachia bacteria, which stops them from reproducing and slowly collapses the wild population from within. Google's previous Debug Project trial in California's Central Valley nearly eliminated mosquitoes from three test sites entirely. A separate trial in Singapore cut dengue cases by 70% within 12 months. Google has now released over 1 billion mosquitoes across four continents. This new proposal is the largest deployment in US history.

Founders of the largest AI companies had worries about AGI before they even started their companies, yet they’re often accused of raising those concerns for regulatory capture. I suspect whole-brain emulation companies may face the same pattern.

Earlier this month I joined @Netholabs as Chief Product & Data Officer. We're building neurobehavioral models. Really excited to share more as we make progress towards whole brain emulation! We're hiring ML engineers. DM me your best achievement if interested!

This may be the fastest race in swimming history… James "The Missile" Magnussen is 6'6", 35 yrs old, 2x world champion, and Olympic medalist. I'm commenting the @enhanced_games tomorrow night where James is competing. Insane stats on him... #1 His resting heart rate is 28 bpm (cleared by his medical team). For context, elite endurance athletes are typically 40–50 bpm. Mine is around 39-42 bpm. #2 Last year he was 253 lbs. This was after his first cycle of performance-enhancing-drugs. He got too big. He was sinking in the water. He's down 40 lbs this year to try and hit the sweet-spot of muscle and buoyancy. #3 He's so big he can barely fit into his enhanced suit. Enhanced Games swimmers wear full-body polyurethane "supersuits" that World Aquatics banned in 2010. These are the same suits that broke 43 world records in 2009. #4 He came out of a 7-yr retirement for this. He retired from competition in 2019. Tomorrow night, I'll be reviewing their protocols and measurements live.
