Making Movies with Nanoscale Resolution
In an example of an extreme movie close-up, researchers have used a subwavelength-resolution technique to track synaptic vesicle movement at video rates. Scientists from Max Planck Institute for Biophysical Chemistry and from European Neuroscience Institute, both in Göttingen, Germany, followed the movement of vesicles — small, hollow vessels that transport biochemicals — as they traveled in boutons, the knoblike enlargements at the ends of nerve cells that form synapses.
