Nanomachines and molecular motors can make use of thermal noise

Posted by Jim Lewis on July 3rd, 2012

A theoretical study shows that although thermal noise cannot be used to produce useful motion by mesoscale or macroscale machines, it can be used by nanoscale machines without violating the second law of thermodynamics.

An expanded genetic alphabet could lead to more easily designed proteins

Posted by Jim Lewis on June 22nd, 2012

The demonstration that the process of DNA replication is more flexible than thought should make it easier to incorporate unusual amino acids into designed proteins, which might make it easier to design novel protein machines.
