These revolutions are interconnected, as Kaku notes; discovery of the DNA double helix, for example, relied on X-ray crystallography, a technique derived from quantum physics. Masters of the universe MiTeGen's In Situ-1[TM] crystallization plate (an SBS standard, 96-well microplate) enables X...

Today X-ray crystallography is widely used in materials and biological research. In X-ray crystallography, integrated intensities of the diffraction peaks are used to reconstruct the electron density map within the unit cell in the crystal. To achieve high accuracy in the reconstruction, which is ...
Although X-ray free-electron lasers (XFELs) have facilitated the capture of reaction intermediates using time-resolved serial femtosecond crystallography (TR-SFX), only a few natural photoactive proteins have been investigated using this method, mostly due to the lack of suitable phototriggers. Here...
In macromolecular x-ray crystallography, refinement R values measure the agreement between observed and calculated data. Analogously, R(merge) values reporting on the agreement between multiple measurements of a given reflection are used to assess data quality. Here, we show that despite their widespre...
