Clive Thompson, himself a person with a number of “weird, offbeat obsessions”, writes about the power of curiosity, including the story of how a trip to Yellowstone’s burbling hot springs led to the PCR method that enables accurate Covid testing.
Tags: Clive Thompson scienceBack in 1964, the microbiologist Thomas Brock visited Yellowstone National Park to do some sightseeing. He was on a long car ride, and wanted to break up the monotony.
While peering into the hot springs, he noticed a curious blue-green tinge. When he asked a park ranger about it, he was told it was algae. That surprised Brock: Those pools are so hot that some of them reach a boiling temperature. At the time, scientists didn’t know of many lifeforms that could readily thrive such scalding environments.
But Brock couldn’t stop wondering about what exactly was going on in those boiling pools. He was dying to know: What was alive down there? How was it surviving?
