This is cool, but extremely icky.

voma writes "Tiny robots powered by living muscle have been created by
scientists at the University of California, Los Angeles. The devices were
formed by "growing" rat cells on microscopic silicon chips, the researchers
report in the journal Nature Materials. Less than a millimetre long, the
miniscule robots can move themselves without any external source of power.
Muscles like these could be used in a host of microscopic devices - even to
drive miniature electrical generators to power computer
chips."
