: '''Penicillin (1928/1941)''' → The "Yellow Magic" that saved the Allies in WWII and added 20 years to the average human lifespan.
: '''The 'Discovery Void' (1987-Present)''' → The fact that "No new class" of antibiotics has been discovered since the late 1980s. We are "Running out of ammo."
: '''MRSA''' → A common hospital superbug that is "Immune to almost everything," forcing doctors to use "Toxic, Old-fashioned" drugs as a last resort.
: '''Phage Therapy''' → Using "Viruses that eat bacteria" (Bacteriophages) as a "Living Medicine" to kill superbugs that are immune to chemicals.
