Biophysicists unravel cellular 'traffic jams' in active transport

Researchers at UMass Amherst use a custom microscope to study cellular active transport, discovering that high traffic slows cargo movement but doesn't hinder the process. By using quantum dots as biological probes, they found that multiple motors attached to a single cargo can overcome stalled motors and maintain efficient transport.
