Chaperones enable newly synthesized proteins to adopt the precise three-dimensional conformation that is necessary for their biological function. Little is known about the changes in molecular structure of chaperones as they help substrate proteins to fold. Now, researchers have been able to follow in real time the structural changes that occur in an important type of chaperone as it coaxes an unfolded substrate protein into shape.

Scientists are reporting first use of a new method that may make it easier for manufacturers to recover, recycle, and reuse nanoparticles, some of which ounce for ounce can be more precious than gold. The method, which offers a solution to a nagging problem, could speed application of nanotechnology in new generations of solar cells, flexible electronic displays, and other products, the scientists suggest.
