What happened

Hair-size microrobots combine three cancer-fighting functions in preclinical animal tests Gaby Clark Scientific Editor Andrew Zinin Lead Editor Imagine a future where cancer treatment affects only the tumor, where eye injections are no longer required and…

Why it matters

That's the future researchers at Michigan State University are working toward.

Common ground

Their goal is to make medical care easier on patients by using tiny biodegradable tools that can travel through the body and deliver treatment exactly where it's needed.

Perspective signals

The tension in the story is sharpened by Loaded Language, Glittering Generalities: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
