Opportunities

• New Limit (longevity tech) is hiring for data scientists in computational biology (via @brian_armstrong)
• Anton Howes has “an idea for a paper that ought to radically revise the currently prevailing Crafts estimates for the impact of steam engines on British GDP pre-1800…. if this sounds like a paper you’d like to work on, then DM me”
• Entrepreneur First is hiring a US Chief of Staff (via @matthewclifford)

News & announcements

• Georgia Power declared Plant Vogtle Unit 3 commercially operational on July 31, making it the first “newly constructed” nuclear power unit to be added to the US fleet in decades (via @Sonalcpatel)
• Wendy’s announced they will be the first to launch Pipedream’s “Instant Pickup”
• A Japanese cyclotron has created sodium-39, an extremely unstable isotope
• UK privacy bill poses serious threat to encrypted communications?
• A previous announcement quoted @ylecun saying that “Llama-v2 is open source.” Zac Hatfield-Dodds claims this is wrong: “Meta is only offering a limited commercial license which discriminates against specific users and bans many valuable use-cases, both economic and in alignment research.” Zac works for Anthropic, although I assume this opinion is his own.

Superconductor update

• If it worked, could a superconducting induction coil make the perfect battery? And would it be world changing?
• Casey Handmer, a week ago: “I have a PhD in theoretical physics, studied BCS theory… I still have no strong intuition on LK99.” Since then—
• Something has been replicated with LK-99. You can follow a formula, make some sort of compound, and it floats when you put a magnet near it. But—
• The Condensed Matter Theory Center has good news and bad news. And more good news and bad news. But it’s mostly bad news. And: “LK-99 is likely simply a ferromagnetic material, which explains its levitating properties, according to new research from Peking University.” Here’s a good summary of what happened, which adds “high-low resistivity transition is likely due to Cu2S contamination”
• The Kalshi and Manifold markets have tanked
• Closing thought: Superconductor or not, LK99 came out of left field. But one can say the same about the last three discoveries of high temperature superconductivity
