Subwavelength anti-diffracting beams propagating over more than 1,000 Rayleigh lengths
Monday, 03.02.2015, 03:13pm
Researchers take advantage of the nonlinear response of a dipolar glass and observe non-paraxial propagation of a sub-micrometre-sized beam over 103 diffraction lengths.
Sub-100 nm resolution microscopy based on proximity projection grating scheme
Thursday, 02.26.2015, 11:02am
Here we present an approach to structured illumination microscopy using the proximity projection grating scheme (PPGS), which has the ability to further enhance the SIM resolution without invoking any nonlinearity response from the sample. With the PPGS-based SIM, sub-100 nm resolution has been obtained experimentally, and results corresponding to 2.4 times resolution improvement are presented.
Atomic-accuracy models from 4.5-Å cryo-electron microscopy data with density-guided iterative local refinement
Monday, 02.23.2015, 03:32pm
New detector technology has improved the resolution of cryo-electron microscopy (cryo-EM), but tools for structure determination from high-resolution maps have lagged behind. DiMaio et al. report structure determination from high-resolution cryo-EM maps using a homologous structure as a starting model. Also online, Wang et al. describe a de novo approach for structure determination that does not require a starting model.
Myosin II controls cellular branching morphogenesis and migration in three dimensions by minimizing cell-surface curvature
Friday, 02.13.2015, 12:26pm
Elliott et al. use high-resolution imaging, microfabrication and computational analyses to show that the interplay between cell-surface curvature and activity and cortical recruitment of myosin II, control cell migration in 3D matrices.
A general method to improve fluorophores for live-cell and single-molecule microscopy
Wednesday, 02.04.2015, 12:15pm
A simple and general chemical structure change to a panel of cell-permeable small-molecule fluorophores increases their brightness and photostability, which will enable improved single-molecule studies and super-resolution imaging.
Imaging liver biology in vivo using conventional confocal microscopy
Monday, 02.02.2015, 10:57pm
This protocol describes how to perform liver confocal intravital microscopy in mice, revealing the morphology and function of hepatocytes, endothelial cells and leukocytes in their native environment under physiological or pathological conditions.
