The oscillating synthesis and degradation of regulatory RNA molecules was used to produce a molecular clock to control the opening and closing of a DNA tweezers, and also to control the production of another RNA molecule to alter the fluorescence of a dye molecule.

The Singularity University Executive Program recently took on the challenges of advanced nanotech: Nanotechnology: How should we evaluate the environmental impact of human-made machines that are too small to see? What limits should be placed on self-replicating nanodevices? What defenses should we institute against malevolent uses of such technology? These questions were asked by Marc [...]
A complex piece of DNA that acts as a biological computer when it is inserted into cells determines whether or not the cell is a specific type of cancer cell, and if so, initiates the suicide of that cell.
Electrons from a scanning tunneling microscope cause a molecule of butyl methyl sulfide to rotate about a single sulfur atom attached to a copper surface.
News articles by Jon Cartwright on the Chemistry World news site and by Michael Berger at Nanowerk describe a significant molecular machine milestone achieved by the research groups of David A. Leigh (winner of the 2007 Foresight Institute Feynman Prize in Nanotechnology for Theory) and Anne-Sophie Duwez. The research was reported in Nature Nanotechnology [abstract]. [...]
