  • a discovery he declined to patent.

  • Other scientists took interest in the Gila monster,

  • and eventually those molecules became the foundation for GLP1 drugs like Ozempic and Mounjaro.

  • These drugs are best known for their help treating diabetes and obesity.

  • But recent studies have raised hopes that they could address chronic kidney disease,

  • reduce the risk of heart problems, and even cognitive issues and addictions to opioids.
