Fastest cell

On 3 December 2011 the American Society for Cell Biology announced the results of their first World Cell Race, in which some 50 labs across the world chose different types of cell to compete in a race along a 0.4-mm race track. The winner was a line of fetal mesenchymal bone marrow cells from Singapore, which were clocked at 5.2 microns per minute, or 0.000000194 miles per hour.
