177 problems carry medicine and public health

The largest field in the collection. Health contributes problems where good science stalls before it reaches patients: farm antibiotics breeding resistance to medicine's last-resort drug, France needing to prove the absence of bird flu after vaccinating 35 million ducks, and lab results — cell lines, antibodies, preclinical cancer studies — that quietly fail to replicate. Many of these are less about inventing a cure than about measurement, trust, and delivery.
