Scientists at the University of Kentucky, led by nano-biotechnologist Peixuan Guo, have made some critical discoveries over the past year into the operation of biomotors, the molecular machines used by viruses and bacteria in the packaging of DNA.
Biomotors function similarly to mechanical motors but on a nano-scale. Last year, Guo's team reported the discovery of a new, third class of biomotor, unique in that it uses a "revolution without rotation" mechanism. Rotation is the turning of an object around its own axle, as the Earth does every 24 hours. Revolution is the turning of an object around a second object, as the Earth does around the sun.
