Ever wonder how Captain America survived entombed in ice for so long? Marvel Avengers S.T.A.T.I.O.N. at Treasure Island in Las Vegas offers an answer to that question -- and it's not Super Soldier serum.
Reddit user darthalex22 uploaded a photo from the exhibition that explains:
Physical examination of Capt. Rogers revealed that while thickened, his blood's water was not frozen. Blood test revealed that his blood contained excessive amounts of glucose as a result of his liver processing his glycogen stores, thus lowering the freezing temperature of blood-borne water and creating a "cryoprotectant." This process is similar to that of Water-Bears (Tardigrades) and hibernating Wood Frogs who metabolize glycogen in their liver to circulate copious amounts through their body to reduce the osmotic shrinkage of cells and stop from freezing. This, however, has never been seen before in humans.
Marvel Avengers S.T.A.T.I.O.N. is an interactive and educational exhibit, designed to look like a S.H.I.E.L.D. facility, that brings visitors into the world of Earth’s Mightiest Heroes. Along with props from multiple Marvel Cinematic Universe films, including Captain America’s uniform and shield, Black Widow’s jumpsuit and Iron Man’s Hulkbuster armor, the S.T.A.T.I.O.N. also includes exclusive intelligence files, classified studies and, apparently, the science behind one of Marvel’s most enduring mysteries.
The exhibit is open daily from 10 a.m. to 10 p.m. inside of Las Vegas’ Treasure Island casino.
