Scientists have created "zombie" mammalian cells that function better after they die. Although creating "zombie" cells may seem like a dubious endeavor, it has quite a few practical applications. Researchers at Sandia National Laboratories and the University of New Mexico coated a cell with a silica solution. This created a near-perfect replica of the structure that could simplify a wide variety of commercial fabrication processes. In fact, the process allowed the researchers to preserve cells down to the minor grooves of its DNA.
