Fitting a mechanistic model to data from SARS-CoV-2 source-recipient pairs generates improved estimates of changes in infectiousness during infection, indicating substantial transmission shortly before symptom onset.
Proximity-labeling using engineered biotin ligases TurboID and miniTurbo enables detection of cell-type-specific and low abundance protein complexes and subcellular proteomes in Arabidopsis and other plants.
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.
Cuticulosomes are organelles found in the hair cells of birds that are composed of ferritin nanoparticles, form rapidly after hatching by the fusion of vesicular structures, and may play an indirect role in magnetic sensation.
The remarkable lifelong stability of mechanotransducing stereocilia of the inner ear hair cells depends on the activity of the transduction ion channels located at the tips of these mechanosensory projections.
