There is considerable interest in understanding transport and information pathways in living cells.

Using large-scale computer simulations, researchers at the Georgia Institute of Technology have identified the most important factors affecting how molecules move through the crowded environment inside living cells.

A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his group have done so.

Microscopic objects floating in fluids move great distances at times, not just in a bell curve, disputing an Einstein theory, a U.S.

PITTSBURGH, April 29 /PRNewswire-USNewswire/ -- High school and undergraduate students now have a ringside seat to watch atoms and molecules in super-slow motion and vivid color, as they jostle and bump each other within the cozy environs of a human cell or a beaker on a lab bench.
