What happened

Scientists discover learning and memory formation in model membranes Gaby Clark Scientific Editor Robert Egan Senior Editor A decades-long collaboration between two scientists at the Department of Energy's Oak Ridge National Laboratory is reshaping how we…

Why it matters

Their findings suggest that cellular membranes play a direct role in how memory and learning form in the brain.

Common ground

This work aims to advance materials science for neuromorphic, or low-power, brain-inspired computing technologies and research on neurological disorders.

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.
