Iowa Doctor Wins Top Award for Cystic Fibrosis Breakthrough

A violent cough down the hospital hallway changed everything for Dr. Mike Welsh.

In the early 1970s, Welsh was a medical student when he met a young girl, maybe 7 or 8, struggling to breathe through thick mucus filling her lungs. She had cystic fibrosis, and her doctor delivered the grim reality: she probably wouldn't survive her teens.

That little girl became Welsh's inspiration for nearly 50 years of research. His work just earned him the 2025 Lasker Award, often called the "American Nobel," for creating medications that turned CF from lethal to livable.

The breakthrough came from an unexpected place: frog eggs.

Welsh discovered that in CF patients, chloride gets trapped inside cells, pulling water out of the lungs and creating thick, deadly mucus. He was trying to fix the broken protein responsible when he noticed another researcher's work showing chloride movement in their experiments.

The secret was in their methods section. They had used frog eggs, which are kept much colder than human cells.

Welsh's team lowered the temperature in their lab. 30 degrees Celsius. Then 26. Then 23. Colder and colder, until something remarkable happened: the broken protein started working.

That discovery led to a series of medications that patients can now take as pills. For people like William O'Neal II, who was given three months to live at age 20 without a lung transplant, the drug arrived just in time.

Within weeks of starting treatment in 2019, O'Neal was walking without gasping and talking without stopping for air. "That was the first time I knew the drug was a miracle," says O'Neal, now 27 and a poetry fellow at Iowa Writers' Workshop.

Grace Lidgett felt the same transformation at 21. "My lungs were just clearing these things that had probably been sitting in the bottom of them forever," she remembers. The student who once struggled to breathe became a triple qualifier in Iowa's state high school cross-country and track competitions.

The Ripple Effect

Welsh's curiosity about one struggling child created waves that reached thousands. His systematic approach to understanding exactly how CF breaks the body gave scientists a roadmap to fix it.

The medications don't just extend lives by a few years. They fundamentally change what a CF diagnosis means, transforming patients from people awaiting transplants into athletes, students, and parents planning long futures.

His work shows what's possible when researchers refuse to accept that suffering is inevitable, when they keep asking questions until the answers emerge.

Sometimes the path from a child's cough to a life saving cure runs through the most unexpected places, like frog eggs kept at just the right temperature.
