Claude Helped Anthropic's Biologists Map the First Vault Particle From Bacterial Life
Claude Helped Anthropic’s Biologists Map the First Vault Particle From Bacterial Life
Vault particles were found in 1986, they are among the largest protein structures in our cells, and nobody knows what they do. On Wednesday Anthropic’s biology team said that, working with Claude, it had determined the first 3D structure of one from prokaryotic life: a bacteriophage protein called L05 that assembles into a barrel of 96 copies, against 78 in the mammalian vault, and holds about 25% more volume. Claude searched some 15 billion predicted proteins for relatives; of 15 candidates that made soluble protein, 7 formed vault-like particles and cryo-EM confirmed 4. The speed-ups are concrete — purification from about three days to 90 minutes, a first model 34 hours into processing, the whole project in under four months. So are the mistakes: a Claude-written protocol cost two weeks, and an early skipped step produced a map blended with its own mirror image, until the researchers asked it to “do normal things unless they don’t work.” What vaults are for is still open. Faster ignorance is still progress.

OpenAI’s Agents Wrote 948 Working Linux Exploits for $1.2 Million, Then Handed Them to the Defenders
Patch the Planet, OpenAI’s open-source security pipeline, was last here in October over PHP flaws. What is new is the scale. In a thread late on Wednesday OpenAI said an expanded run reproduced 1,724 vulnerabilities and produced working exploits for 948 distinct Linux local privilege-escalation bugs, plus proofs of concept for 291 information leaks — all against a stock Linux desktop with standard protections on. The agents also found at least 10 exploitation techniques that OpenAI and the experts it consulted believe are novel. The bill: $1,213,430 in API credits, about $1,279 per bug, against a hypothetical $18.9-66.3 million at historical Pwn2Own and TyphoonPWN bounty rates. Human researchers review the results before anything goes to maintainers, and OpenAI says it is working with Linux maintainers on the patches. The same machine that finds a path to root at $1,279 a time is available to people who will not file a report.

Apple Opens Siri AI to Every App on the Day It Warned Investors About AI Agents
On Tuesday Apple filed its annual report and listed AI agents as a risk: they “may behave in unintended or unpredictable ways,” can act on their own by “executing or altering code, sending communications, and completing transactions,” and Apple’s ability to “oversee and control third-party artificial intelligence agents” may be limited. The same day its developer site announced that “Siri AI is now open to all developers”: from the iOS 27.3 betas, any app can hand its content and actions to Siri AI through App Intents, from “checking a delivery to booking a reservation to placing an order,” and new “skills” let it chain several actions into one request. It is a preview: customers get it “in a few months,” App Store submissions open in the spring, it is unavailable in the EU on iOS, and Apple says heavier use “will be available for a fee in the future.” The risk section and the product launch, filed on the same Tuesday — at least nobody can say they weren’t warned.
