Show HN: Runtime security enforcement and capability scoping for agentsIMAGE

Show HN: Runtime security enforcement and capability scoping for agentsHi everyone. We're AI researchers at Harvard and Carnegie Mellon working on a project to advance the state of agent security. Currently, many systems rely on static sandboxing, which in long-running sessions enables agents to understand the safeguards holding them in place and break out of them. We've found vulnerabilities across over a dozen agent providers and frameworks (practically every one we tested) displaying this behavior (eg. a model fraudulently splitting payments to avoid a company-set payment limit, multi-model agent teams infecting each with injections, MCP rug pulls, etc).We've developed an architecture that does two things: 1) instead of setting a sandbox for a session and leaving it in place, dynamically scoping the sandbox to cover the minimum subset of capabilities and file accesses that are needed for solving a particular problem set by the user, and continuously moving that sandbox to be in line with what the user wants. Think of this as, instead of a large station

Show HN: ClawGPT – Chat UI with E2E encrypted phone sync, zero dependenciesIMAGE

Show HN: ClawGPT – Chat UI with E2E encrypted phone sync, zero dependenciesI built this because the default web UI for my local AI setup (OpenClaw on a Jetson Orin NX) was too bare for daily use. I wanted something I could hack on without dealing with a build toolchain, so the whole thing is plain HTML, CSS, and JavaScript. No React, no npm, no webpack. Open the file, it works.Features that might be interesting to HN:- Edit any message in a conversation (not just the last one), with automatic conversation branching - E2E encrypted phone sync via QR code. X25519 key exchange, XSalsa20-Poly1305 encryption, new keys per session. The relay server only sees ciphertext. Self-hostable. - Voice input with push-to-talk on mobile - Semantic search across all conversations - Per-message model switching - Full export/import of all data as JSON - Agent-readable conversation memory (writes JSONL to disk so AI agents can access chat history)The phone sync was the hardest part. Both devices connect to a relay room, do the key exchange, then verify via shared words displayed

Auroral radio signal offers new insight into intense magnetic stormsSouthampton, UK (SPX) Dec 03, 2025 A University of Southampton team has identified a distinct low frequency radio signature that appears when small-scale auroral structures known as auroral beads emerge, providing a new clue to how intense auroral substorms are triggered. Magnetospheric substorms are bursts of activity in Earth's aurora that can rapidly transform faint arcs into bright, dynamic displays stretching across th

Haystack scientists study recent geospace storms and light showsBoston MA (SPX) Nov 15, 2025 The northern lights, or aurora borealis, one of nature's most spectacular visual shows, can be elusive. Conventional wisdom says that to see them, we need to travel to northern Canada or Alaska. However, in the past two years, New Englanders have been seeing these colorful atmospheric displays on a few occasions - including this week - from the comfort of their backyards, as auroras have been vi

Helio Highlights: May 2025The Sun is 93 million miles away, but its presence is felt strongly even at this distance. One of the more beautiful effects of this presence are the auroras which light up the sky in the Northern and Southern polar regions. These displays, also called the Northern and Southern Lights, are caused by interactions between particles of energy from the Sun and the molecules in the atmosphere above Earth’s poles.
