For years, scientists thought nothing could live above 73℃/163℉. At that temperature, everything boiled to death. But scientists Tom Brock and Hudson Freeze weren’t convinced. What began as their simple quest to trawl for life in some of the hottest natural springs on Earth would, decades later, change the trajectory of biological science forever, saving millions of lives—possibly even yours.

This seismic, totally unpredictable discovery, was funded by the U.S. government. This week, as the Trump administration slashes scientific research budgets en masse, we tell one story, a parable about the unforeseeable miracles that basic research can yield. After that, a familiar voice raises some essential questions: what are we risking with these cuts? And can we recover?
