By Peter Aldhous A SCUM-DWELLING pond microbe is the inspiration for minute springs that bioengineers hope will operate tomorrow’s miniaturised devices. Danielle France at the Massachusetts Institute of Technology is studying a protozoan called Vorticella convallaria, which can attach itself to rocks, lily pads and even other creatures in the plankton using a stalk called a spasmoneme. When the protozoan is disturbed, the spasmoneme contracts abruptly, like a stretched telephone lead springing back into a coiled shape. “We think that it operates on stored energy,
