With all of today’s talk about ricin found in Las Vegas, I have to tell a little story. I remember first learning about ricin way back in Prof. Krieger’s 7.20 class (Human Physiology) in college. The class distinguished itself from most other biology-major fare by being immediately and directly applicable to real life. The mention of ricin, however, was especially memorable to me because it was mentioned in the setting of the Bulgarian umbrella murder. It wasn’t a particularly positive use of biology, but I was pretty impressed. Espionage! Assassination! Secret spy gadgets! All made possible with science. If I remember correctly, one single molecule of ricin was capable of killing a human cell. That’ll make you pay attention.
