What’s the tough thing about underwater demolition and other operations is the water? It’s cold. Even with wet suits, military divers can only stay underwater so long. Now a team working for the Office of Naval Research has found a way to give neoprene wetsuits insulating power nearly equal to the fat on a seal.
