Design Patterns for Securing LLM Agents against Prompt Injections This new paper by 11 authors from organizations including IBM, Invariant Labs, ETH Zurich, Google and Microsoft is an excellent addition to the literature on prompt injection and LLM security. In this work, we describe a number of design patterns for LLM agents that significantly mitigate the risk of prompt injections.

Trump’s Cuts Threaten Nobel-Winning Observatory That Detected Colliding Black Holes

Nearly 10 years ago, scientists observed ripples in spacetime created by the collision of two black holes that took place 1.3 billion years ago. The first direct detection of gravitational waves opened up an entirely new way of seeing the universe, allowing us to observe a once invisible side of the cosmos. Today, the ability to track the frequencies produced by the most notable events that shape our surrounding cosmos is at risk due to drastic budget cuts targeting a breakthrough observatory.
