Groupthink Must Die
Tiny swimming bio-bots boldly go where no bot has swum before
"The bio-bots are modeled after single-celled creatures with long tails called flagella – for example, sperm. The researchers begin by creating the body of the bio-bot from a flexible polymer. Then they culture heart cells near the junction of the head and the tail. The cells self-align and synchronize to beat together, sending a wave down the tail that propels the bio-bot forward."
