Blue-light tools let researchers track, redirect and sever cells' transport routes

AI Summary

Researchers have developed blue-light tools to observe and manipulate transport routes inside cells, including redirecting or severing those routes. The work points to a method for studying cellular processes with precise control, though the description does not provide further experimental details.

Light is fundamental to human life—without it, we'd be hungry, cold and blind. But what if the same light that sustains us could also be used to control and observe parts of cells within our bodies?
