"  It turns out that tiny biological processes are mechanically apt. The latest research in nanobiomechanics has revealed a series of natural &amp;quot;springs&amp;quot; fit into a single molecule.  The springs are made from building blocks of ankyrin proteins with 33 amino acids folded into tiny ribbon-shaped repeats. These repeats are stacked side by side to make a larger connected structure. Like parts of a car engine, the springs have mechanical potential, but their biological utility is not yet understood. Researchers hope to reveal the role of the springs in the proteins to better understand the biological machines in molecules and apply this to current nanotechnology.--Tyghe Trimble "^^<http://www.w3.org/2001/XMLSchema#string>
