Large-scale in vivo imaging of the zebrafish left-right organizer (Kupffer's vesicle) combined with fluid dynamics calculations allows to quantitatively test the possible flow detection mechanisms and supports the flow transport of chemical signals as the mechanism of side determination.
Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.
A comprehensive whole cell proteomic map describing expression time courses of >6,500 viral and cellular proteins during HIV infection identifies Vif-dependent antagonism of key cellular phosphatase PP2A.
Co-evolving residue pairs in the different components of a protein complex almost always make contact across the protein–protein interface, thus providing powerful restraints for the modeling of protein complexes.
Regional differences in activator and inhibitor signals alter hair cycle pace across mouse skin and produce unique fur renewal 'landscapes', with fastest renewal on the ventrum and slowest renewal on the ear pinnae.
