NOW we can watch protein nanomachines MOVE

with

Neutron Spin Echo spectroscopy! Protein nanomachines are far more complex than any molecular machines yet constructed.

Their skillful utilization likely represents the future of medicine.

Neutron spin echo spectroscopy (NSE) is the only experimental technique that can determine protein motion on nano length and time scales. Such motions have long been hypothesized to be the most significant modes for protein function. We have developed a theoretical framework that allows one to interpret the NSE data. Our theoretical framework uses simple concepts from nonequilibrium statistical mechanics, and does not require elaborate molecular dynamics simulations, complex fits to rotational motion, or elastic network models. In combination with our experimental methodology of selective deuterium labeling, our work clears significant hurdles to the understanding of this very important problem.

Read all about it HERE! Interdisciplinary nanoscale biophysical approaches to the cure of disease were once thought revolutionary, but are now rapidly becoming a standard part of the repertoire. We have instituted a new multidisciplinary program of research in this area, headed by Professor David Callaway.

Dr Callaway has worked extensively in the field of Alzheimer's disease, specifically in understanding and controlling amyloid formation. His Alzheimer's program has developed and patented several potential therapeutics for Alzheimer's disease, based upon apomorphine, which are reviewed in a Wikipedia article.

Trained as a theoretical physicist, Dr. Callaway has published research on topics ranging from elementary particles, black holes, semiconductors and superconductors to protein dynamics and structure-based drug design. Presently he works on probing protein domain dynamics by neutron spin-echo spectroscopy, allowing us to observe protein nanomachines in motion.
