Nano springs eternal; Protozoan 'engine' posts nano records

Looking through his handmade microscope in 1702, it was Anton van Leeuwenhoek who first described the workings of a nano machine. He observed the rapid contraction of a stalk tethering the cell body of a tiny protozoan, Vorticella convallaria, to the surface of a leaf. Little did van Leeuwenhoek imagine that more than 300 years later, the biological spring that drives Vorticella would set records for speed and power in the nano world of cellular engines.
