How curiosity about jellyfish, fungi, snake venom, and desert lizards led to modern medicine's most transformative drugs—from statins to CRISPR. Peter Atiyah traces six breakthrough discoveries that began as basic science with no obvious clinical goal, revealing why nature's 4-billion-year toolkit holds solutions we're only beginning to recognize. Osamu Shimomura spent 19 summers catching jellyfish to understand bioluminescence, discovering green fluorescent protein (GFP), which transformed modern cell biology and became essential to virtually every biomedical research lab worldwide.
