Pigs in Diving Suits Help Scientists Understand Decompression Sickness

In the long human effort to descend safely into the deep and return whole, researchers have found an unexpected ally in thermal stability — and an unexpected subject in the pig. By fitting swine with heated diving suits and monitoring their physiology under controlled pressure, scientists have uncovered evidence that body temperature plays a meaningful role in whether nitrogen, absorbed silently at depth, becomes a bubble that harms or a gas that passes harmlessly away. The work is preliminary, but it points toward a future where warmth itself becomes a form of protection against one of diving
