Honeybees teach drones how to navigate

It sounds like science fiction, but also strangely familiar: drones buzzing around, inspecting tomatoes in greenhouses, delivering your package or inspecting an industrial site. With all the talk about drone-swarms, development ...

Tiny, knotted robots jump, fly and plant seeds

When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot can do. Instead of treating it as something that holds tension, they asked a different question: ...

Making big tech algorithms 'fair' is harder than it looks

Before big tech engineers can improve the fairness of recommendation systems, such as social media feeds and online shopping results, they need to define what "fairness" even means. Should an app show people only the content ...
