'Lego' Approach Thwarts Anthrax Toxin

NewScientist is reporting that scientists have discovered complex nanoscale structures that have successfully protected rats from anthrax. From the article: "The technique relies on using tiny 'peptide' molecules, stuck onto one large molecule, which bind to toxins and prevent them from causing damage. They do this in much the same way that two Lego bricks might fit together - with several studs from the binding molecule slotting into, and so blocking, the sites on a toxin molecule which are needed to cause damage."
