In 1928, which discoveries were made?

• A. Anesthesia was discovered in 1928
• B. Penicillin and cancer cells were discovered in 1928
• C. The first heart transplant occurred in 1928
• D. The smallpox vaccine was discovered in 1928

Answer: (B)

Penicillin’s discovery in 1928 marks the notable breakthrough here. Alexander Fleming noticed that a mold contaminating one of his petri dishes had killed surrounding bacteria, leading to the identification of penicillin, the first true antibiotic. This event changed medicine by providing a powerful tool to treat bacterial infections and laid the groundwork for the antibiotics that transformed healthcare in the 20th century. The other items didn’t occur in 1928: anesthesia existed long before, the first heart transplant happened decades later, and the smallpox vaccine was developed in the 18th century. Cancer cells were studied earlier as part of cancer research, not a new discovery in that year.
