Summary:
Even robots can use a heart. Or heart cells, at least. A new stingray bot about the size of a penny relies on light-sensitive heart cells to swim. Zaps of light force the bots fins to flutter, letting researchers drive it through a watery obstacle course.
"Heart Cell Stingray Driven by Light" is from the August 6, 2016 issue of Science News.
