The Man Who Proved Your Body Runs on Randomness Just Died
Susumu Tonegawa solved a paradox that stumped immunology for decades: how can limited DNA encode billions of different antibodies? His answer — that immune cells randomly rearrange their own genes — revealed that your body’s defense system runs on controlled chaos. The same mechanism powers mRNA vaccines and cancer immunotherapy today. And when it breaks, it causes autoimmune disease. He proved that randomness isn’t the enemy of order — it’s evolution’s secret weapon.
