Ring Around the Microtubule

Fibers of tubulin attach to kinetochores and play a critical role in the movement and duplication of chromosomes during cell division. The secret lies in a sliding ring, made possible by remarkable interactions between the tubulin and kinetochore proteins.

Light-Powered Pistons

New four-legged molecules change shape and lift themselves above a metal surface when hit with a beam of ultraviolet light. A second beam reverses the action. Smart surfaces, light-triggered nanoswitches, and molecular machines that crawl are in the offing.

A Diamondoid in Your Future

Diamondoids are hydrocarbon molecules with the same carbon-carbon structure as diamonds. Cheap, pure, and capable of self-assembly, they emit electrons at a single energy level, which could make them ideal for the ultra-high-definition, low-powered flat-panel screens of the future.
