Rob and John have a new review on SAXS and its application to systems biology published in the Annual Review of Biophysics. See if you can spot the musical theme. >Small-angle X-ray scattering (SAXS) is a robust technique for the comprehensive structural characterizations of biological macromolecular complexes in solution. Here, we present a coherent synthesis…

A recent IDAT [publication](http://dx.doi.org/10.1107/S0909049512035571) from James, Chris, and Ken investigating the source of the point spread function in detectors using CCDs coupled fiber optic tapers. >The point-spread function (PSF) of a fiber-optic taper-coupled CCD area detector was measured over five decades of intensity using a 20 µm X-ray beam and 2000-fold averaging. The “tails” of…

Hello DOMO users, [DOMO](http://bl1231.als.lbl.gov/domo/) is fairly robust, and is capable of handling your precious crystals mounted in a variety of bases: However, you must take some care when gluing or epoxying the pins into the bases. If there is too much glue or epoxy or you inadvertantly get some on the sides or bottom of…

Summary of Options for Applying for Beamtime at the ALS 1. [RAPIDD](http://www-als.lbl.gov/index.php/component/content/article/701-rapidd-proposal-process.html) – a rapid access process, replaces the 2-month proposal system. SAXS proposals should use the RAPIDD system. MX applicants may apply for either RAPIDD or 6 Month Proposals. The aim is to provide quick turnaround. Proposals are fairly simple, requiring a one page…

We bring to your attention a nice review published recently in the European Biophysics Journal describing the theoretical and practical considerations when using SAXS to characterize macromolecular flexibility. >The dynamics of macromolecular conformations are critical to the action of cellular networks. Solution X-ray scattering studies, in combination with macromolecular X-ray crystallography (MX) and nuclear magnetic…
