Did u know that Tuberculosis can be tested using fire flies? Well it can. They take the enzyme that makes the fire fly glow and add it to a sample of an infected person's saliva in a darkroom. If the sample begins to glow, then the person has active Tuberculosis, if not then it's latent. PRETTY KOOL HUH? I thought u'd think so. Anyway, that's the joy that is my weekend class. Bye bye for now.
