sgunhouse writes: 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 another safety precaution to consider.
Repel them. Repel them. Induce them to relinquish the spheroid.
