Hi all, this is a question off the HYMS website; What do you think is the most important medical discovery in the last 100-200 years and why? There are so many! Off the top of my head I am thinking; Louis Pasteur's germ theory of disease, antibiotics, vaccination, X-Rays, insulin, mapping the structure of DNA, organ transplants, keyhole surgery, stemcell research ... in no particular order... But which is the most important? I really have no idea! Any ideas?!
