While the macroscopic realm is governed by inertia and the microscopic by viscosity, the mesoscale is both and neither, requiring a new set of physics to describe it.<\/p>\n<p>Now, physicists at Aalto University\u2019s Department of Applied Physics have discovered how organisms swim in the mesoscale mix of viscosity and inertia.
