molecular machine

[mə¦lek·yə·lər mə′shēn]
(chemistry)
A molecular device in which the component parts can display changes (reversible movement) in their relative positions as a result of some external stimulus (such as light, electrical energy, or chemical energy), resulting in a signal (a change in a chemical or physical property of the supramolecular system) that can be used to monitor the operation of the device.

Focusing on the work of Gary Lynch and his research team at the University of California, this book shows how cutting-edge science has revealed the inner workings of the molecular machine that manufactures our memories, and the discovery of a new class of drugs that not only enhance brain function but offer tantalizing possibilities for curing many neurological diseases.
Ada E Yonath, who shared the 2009 chemistry prize with V Ramakrishnan for discovering ribosome's translation of DNA information into life, also a major target for new antibiotics in medicine, showed it was looking at the hibernating bears and how they packed their ribosomes before preparing for the harsh winter that she got an insight into how this molecular machine existed beyond environmental conditions.
