In this episode of Lab Rats to Unicorns, John Flavin is joined by Jonathan Gluck—award-winning writer, longtime magazine editor, and now author of the deeply personal memoir An Exercise in Uncertainty: A Memoir of Illness and Hope. For more than two decades, Jonathan helped shape cultural conversations at New York Magazine, Vogue, The New York Times, and The Washington Post. But in his book, he turns the lens inward, chronicling his unexpected cancer diagnosis, the maze of the healthcare system, and the breakthroughs in biomedical research that helped him outlive the odds.

From his first shocking diagnosis of multiple myeloma in his late thirties to the cutting-edge therapies like CAR T-cell treatment that have sustained him two decades later, Jonathan’s journey reflects both the fragility and resilience of the human spirit. Along the way, he shares how writing helped him process uncertainty, why patient storytelling matters for science and society, and what lessons living “one stone at a time across the river” can offer to entrepreneurs, innovators, and anyone facing the unknown.
