FIRST-EVER IN-UTERO STEM CELL THERAPY FOR FETAL SPINA BIFIDA REPAIR IS SAFE, STUDY FINDS

A research team at UC Davis Health has safely performed a spina bifida treatment combining fetal surgery with stem cells. The therapy involved adding a layer of human placenta-derived stem cells to standard fetal surgery. Putting stem cells into a growing fetus was a total unknown, but the team reported great safety.

THE ARCHITECTURE BEHIND OPEN-SOURCE LLMS

In the open-weight ecosystem, teams build on each other's innovations to compound the pace of progress. This post looks at various open source models and the engineering bets that define each one. Every major open-weight model released at the frontier since 2025 uses a Mixture-of-Experts transformer architecture. Almost every 'open source' model is actually open weight - this means the trained parameters are public, but the training data and often the full training code are not.

YOUR AGENT NEEDS A HARNESS, NOT A FRAMEWORK

A harness is a layer that connects, protects, and orchestrates components without doing the work itself. Every agent framework is trying to build its own harness from scratch, but durable, event-driven infrastructure already solves this. Utah (Universally Triggered Agent Harness) is a conversational Telegram or Slack agent with tools, memory, sub-agent delegation, and full durability - a durable, cloud-ready OpenClaw. It was created to prove that durable, event-driven infrastructure can be used to create an agent harness that decouples orchestration from the agentic loop.

THERE IS EXACTLY ONE WAY THAT SAAS CAN BE SAVED

Intercom found success as a late-stage SaaS company in AI. Three years ago, its future was looking pretty bleak as the company was heading quickly towards negative growth. It launched a new service agent called Fin in the summer of 2023, after which its business began to violently recover. The process involved destroying many parts of the business and creating new things. It was difficult, but the company is now at $400M ARR overall, with overall growth rates doubling for the past two years.

CLAWED

US policy has become increasingly unpredictable, thuggish, arbitrary, and capricious. Even if threats against Anthropic are scaled back, great damage has been done. The government has shown that it will treat homegrown companies like a foreign adversary simply for refusing to capitulate to its terms of business - for having its own opinions on how to, or how not to, deploy its own property. Companies cooperating with the US government will now have to operate under this logic.
