...balls and springs, constantly in motion, and their endless atomic twitching conveys information about their organization, Zanni says. Infrared laser beams can detect the minute vibrations and identify characteristic patterns to deduce protein structures.

...ty," the capacity of embryonic stem (ES) cells for endless division has its limits. After a very extended childhood spent dividing in a culture dish, even stem cells tend to grow up and assume adult roles as workaday nerve, muscle, or blood cells, never to return to their youthful state.
