Here’s some news to the world that a lot of good ol’ boys probably already knew.

The importance of this research is that because of a protein in the critter known as Lethal Toxin-Neutralizing Factor — a name that makes sense to ordinary people and actually means what it says and that may be a first in such articles — could ultimately result in development of an anti-venom that would work on pretty much anything.
