(PhysOrg.com) -- The atomic-level action of a remarkable class of ring-shaped protein motors has been uncovered by researchers with the Lawrence Berkeley National Laboratory using a state-of-the-art protein crystallography beamline at the Advanced Light Source (ALS). These protein motors play pivotal roles in gene expression and replication, and are vital to the survival of all biological cells, as well as infectious agents, such as the human papillomavirus, which has been linked to cervical cancer. http://www.physorg.com/news177954624.html Biology Fri, 20 Nov 2009 15:51:16 EST news177954624 In 2004 Lyncean Technologies announced the construction of the Compact Light Source (CLS), a miniature synchrotron which uses inverse Compton scattering to produce high-intensity, tunable, near-monochromatic x-ray beams. The CLS was designed to bring state-of-the-art protein structure determination to the home laboratory -- but it has also promised to have a broad impact across the spectrum of x-ray science. http://www.physorg.com/news150537938.html Physics Wed, 07 Jan 2009 08:05:38 EST news150537938
