In brief Perplexity launched Brain, a memory system for Computer that builds a context graph of past sessions, sources, and corrections—then synthesizes it overnight into a personal LLM wiki loaded before each new task. Perplexity’s own early metrics show Brain boosts answer correctness by 25% on repeated tasks, recall by 16%, and cuts the cost of context-heavy tasks by 13%. Brain is rolling out today in Research Preview for Max ($200/month) and Enterprise Max subscribers; memories are accessible under “Customize” in the sidebar. Perplexity launched Brain today, a memory system for its Computer agent that gets smarter the more you…

Google, for example, has warned organizations to begin preparing for the transition to post-quantum cryptography and has been integrating quantum-safe cryptographic standards into parts of its infrastructure with a 2029 completion target. The U.S. National Institute of Standards and Technology (NIST) has been leading efforts to standardize post-quantum algorithms and has set timelines for the eventual retirement of certain legacy cryptographic systems.Within crypto, several major ecosystems have elevated quantum preparedness as a strategic priority. The Ethereum Foundation earlier this year announced a dedicated post-quantum security initiative aimed at researching migration paths for blockchain’s vast ecosystem of wallets, applications and validators.…
