Scientists Used AI on Blood Type O... The Findings Are Wild

One letter on your donor card may hold more secrets than you ever imagined. When scientists ran blood type O against the medical records and genetic data of millions of people, the findings reshaped what we thought we knew about the most common blood type on Earth. In this deep dive, we explore what blood type O actually is, why its ""null"" antigen structure matters so much in the hospital, and how it's tangled up with malaria, blood clotting, and unanswered questions about human evolution. Along the way, we separate the real science from the popular blood type myths that millions still believe. By the end, you'll know exactly which half of what you've heard about your blood type is true — and which half was never real at all.
