BuzzSkyline writes: Students at UCLA have made the startling discovery that some bacteria can walk on surfaces using structures called Type IV pili as legs. Previously, it was generally believed that bacteria needed to be embedded in fluids to move around significantly. The revelation helps explain the spread of biofilms, and shows why some some bacteria can be particularly dangerous. The professor overseeing the research believes that disabling or lopping off the bacteria legs may offer a novel route to fight infections caused by walking bacteria. The article describing the research has some pretty freaky video of bacteria standing up on one end and walking away.
