High-resolution inelastic X-ray scattering was used to investigate the collective vibrational excitations in hydrated lysozyme powders as a function of hydration level and temperature. It is found that the samples with strong enzymatic function are "soft", in the sense that

Heavy-atom clusters (HA clusters) containing a large number of specifically arranged electron-dense scatterers are especially useful for experimental phase determination of large complex structures, weakly diffracting crystals or structures with large unit cells. Often, the determination of the exact orientation

G-protein-coupled receptors (GPCRs) represent a major class of receptors through which a number of signals ranging from photons to large glycoprotein hormones are recognized. Human genome encodes about 800 GPCRs, yet very little structural information is available on this class

Neutrophils are considered responsible for the pathophysiologic changes during hepatic ischemia-reperfusion (I/R) injury; however, few studies have examined real-time intravital neutrophil recruitment. Here, we show a method for imaging the neutrophil recruitment in hepatic I/R injury using two-photon laser scanning

Type VI protein secretion system (T6SS) is important for bacterial competition through contact-dependent killing of competitors. T6SS delivers effectors to neighboring cells and corresponding antagonistic proteins confer immunity against effectors that are delivered by sister cells. Although T6SS has been
