"Wired has a story up on the lethality of airborne prions. It should be noted that prions (which cause 'mad cow disease' and similar disorders) are not normally airborne, and take a long time to kill the infected animal, but so far are 100% lethal if something else doesn't kill the animal first. So, they are not likely to be useful as a biological weapon (my first thought when reading their headline), but they present another safety precaution to consider."
