Walking with two feet is part of what distinguishes humans from other mammals, so perhaps it’s not surprising that scientists are keen to build two-legged molecules that stroll around with a similar gait.

Nature beat scientists by a few billions years with the evolution of the walking protein motors called myosin, kinesin, and dynein. These biological walkers have two feet that are propelled forward by cycles of conformational changes in multiple protein domains, all powered . . .
