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.

An algorithm helps design peptides that will self-assemble on a given surface to produce a supramolecular structure of desired geometry.
Engineered bacteria that incorporate unnatural amino acids at multiple positions provide a new tool that may facilitate designing proteins to fold more predictably into molecular machinery components.
Automated diffraction tomography provides rapid determination of structure of zeolite to atomic precision.
Ultrasound was used to pull on polymer chains attached to opposite sides of a chemically almost inert molecular ring, splitting it into its two components.
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].… Continue reading First direct measurement of force generated by an individual synthetic molecular machine
Those interested in issues of communication at the nanoscale will be interested to learn that the first volume of the new journal Nano Communication Networks, from Elsevier, edited by Ian Akyildiz, is available free of charge. The volume comprises four issues dated March through December of 2010. Just to pick one article out of dozens… Continue reading Molecular information theory points to robust molecular communications
