Whether you're talking about genes, or neurons, or the workings of a virus, at the most fundamental level, biology is a matter of proteins. So understanding what protein complexes look like and how they operate is the key to figuring out what makes cells tick. By harnessing the unique properties of polarized light, Rockefeller scientists have now developed a new technique that can help deduce the orientation of specific proteins within the cell. By turning their instruments toward the nuclear...

In two new studies, researchers provide the first detailed view of the elaborate chemical and mechanical interactions that allow the ribosome "“ the cell's protein-building machinery "“ to insert a growing protein into the cellular membrane. The first study, in Nature Structural and Molecular Biology, gives an atom-by-atom snapshot of a pivotal stage in the insertion process: the moment just after the ribosome docks to a channel in the membrane and the newly forming protein winds...

A research team led by Edward Yu of Iowa State University and the Ames Laboratory has identified and described two parts of the three-part system that pumps toxins from bacteria and allows them to resist antibiotics. The discoveries are published in the Feb. 24 issue of the journal Nature. The paper describes the co-crystal structure of two parts of the three-part efflux pump that recognizes and removes heavy metal toxins from bacteria. A research team led by Yu "“ an Iowa State...

A theoretical technique developed at the Department of Energy's Oak Ridge National Laboratory is bringing supercomputer simulations and experimental results closer together by identifying common "fingerprints." ORNL's Jeremy Smith collaborated on devising a method -- dynamical fingerprints --that reconciles the different signals between experiments and computer simulations to strengthen analyses of molecules in motion. The research will be published in the Proceedings of the National Academy...

There is considerable interest in understanding transport and information pathways in living cells. It is crucial for both the transport of, for example, medicine into cells, the regulation of cell life processes and their signalling with their environment. New research in biophysics at the Niels Bohr Institute shows surprisingly that the transport mechanisms do not follow the expected pattern. The results have been published in the scientific journal Physical Review Letters. The researchers...

Despite the sophistication and range of contemporary microscopy techniques, many important biological phenomena still elude the precision of even the most sensitive tools. The need for refined imaging methods for fundamental research and biomedical applications related to the study of disease remains acute. Nongjian (N.J.) Tao and his colleagues at the Biodesign Institute at Arizona State University have pioneered a new technique capable of peering into single cells and even intracellular...
