This prosthetic socket hides motion sensors beneath its carbon-fiber shell
A four-person study shows how protected sensors can be built into a socket—and why successful fabrication is not yet proof of better care.

360-degree video catches AI scene models losing track
PersistBench uses a second view of the same moment to test whether dynamic-scene models preserve an object’s existence, motion and appearance after it leaves the frame.

How a 44-gram drone feels its way past transparent walls
Two flexible whiskers turn gentle contact into an estimate of a surface’s forward distance, helping an experimental drone navigate when optical sensing becomes unreliable.

A Gemini security test reached three real companies. The boundary failed first.
The alarming episode shows why AI-safety claims must be judged alongside network controls, target checks, monitoring and the evidence made public afterward.

AI is helping build AI. It has not yet closed the loop.
New measurements show AI writing research code and running experiments, while the crucial work of choosing goals, validating durable gains and producing a better successor remains unproven.

This DNA computer gets answers by settling down
Programmed DNA strands compete for places on a scaffold until the mixture favours an arrangement that encodes the result.

Your coding AI is more than its model name
A controlled study found that memory, planning and tool design can materially change the success and cost of an AI coding assistant while its underlying model stays fixed.

Polonius lets Rust skip an allocation the borrow checker used to demand
A nightly-only borrow-checker upgrade accepts the natural borrowed-key lookup-or-insert pattern, avoiding owned-key construction on cache hits.
