Dead "Zombie" cells outperform living cells in experiment

The so called “zombie cells” are created after coating living cells with a silica solution and then heating the cell at temperatures greater than 400 C (753 F). This process evaporates the proteins within the cell, leaving a three-dimensional nonliving, but nearly structurally identical “zombie cell”. According to Kaehr, the zombie cells are in some ways better than their living counterparts because they are capable of surviving greater pressures and temperatures, and can perform some functions better than when they were alive, saying:
“Once we've used silica to stabilize the cellular structure, it can still carry out reactions and, more importantly, that reaction is stable enough to work at high temperatures.”
