"The fate of the country does not depend on how you vote at the polls -- the worst man is as strong as the best at that game; it does not depend on what kind of paper you drop into the ballot-box once a year, but on what kind of man you drop from your chamber into the street every morning." ~ Henry David Thoreau
“A team of researchers has developed sperm-inspired microrobots, which consist of a head coated in a thick cobalt-nickel layer and an uncoated tail. When the robot is subjected to an oscillating field of less than five millitesla, it experiences a magnetic torque on its head, which causes its flagellum to oscillate and propel it forward.”
