Far from being the story of a lone genius, the triumph of penicillin is actually one of the great stories of international, multidisciplinary collaboration in the history of science. Setting up an IV for patients and administering fluids was not a viable intervention during a cholera outbreak affecting hundreds of thousands of people in Bangladesh or Lagos.

Cells can clean themselves up, they can get rid of old proteins, they can rejuvenate, if you turn on the youthful genes through this reset process.. That hasn't stopped people from spreading rumors online. These initial observations convinced Pasteur that the mysterious changes of both fermentation and spoilage were not a result of spontaneous generation but rather were a byproduct of living microbes, and that insight, which would eventually help provide the foundation of the germ theory of disease, led Pasteur to experiment with different techniques for killing those microbes before they could cause any harm. It took two Oxford scientists Howard Florey and Ernst Boris Chain to turn penicillin from a curiosity to a lifesaver, and their work didnt begin for more than a decade after Flemings original discovery. For much of the 19th century, the overall balance sheet of scientific and technological advances was a net negative in terms of human health: The life-span benefits of one technological advance (variolation and vaccines) were quickly wiped out by the costs of another (industrialization).
