Did you know there's a strain of bacteria that grows in the presence of arsenic called GFAJ-1? Which stands for "Give Felisa A Job?" Felisa is the badass scientist who discovered this strain not too long ago. YOU GO, FELISA. I DON'T KNOW WHO YOU ARE, BUT YOU'RE AWESOME FOR CHOOSING THAT NAME.
Also, this is probably the only thing I'll remember for the current exam that I'm studying for.
