Single molecule imaging reveals how the molecular motor myosin 5 walks in a compass-like spinning motion along its actin track resulting in efficient, robust and unidirectional motion on the nanoscale.
Advanced microscopy techniques reveal that clusters of Pom1 kinase at the membrane represent the functional unit that shape the concentration gradients and modulate Pom1 mid-cell levels according to cell size.
The ability to follow single objects in 3D in a living organism with high spatiotemporal resolution opens new possibilities for quantitative biophysical studies of complex systems in their physiological context.
A toxin is used to introduce an otherwise cell-impermeant fluorophore-antibody (or some thing which is equally specific) to bind to an intracellular protein which allows for super resolution imaging and single particle tracking inside the living cell.
A survey of researchers at the Montreal Neurological Institute and Hospital provides insights into the challenges and opportunities involved in adopting an open science policy across an entire patient-oriented academic institution.
