Scientists have been trying for decades to grow organs as a kind of backup for human parts or as a way to harvest stem cells.And some, quite controversially, have tried creating animal-human hybrids like the humanzee in China, and have conducted studies to find out how long a sheep could carry a human fetus.Experimentation with human biology hasn't been limited to a lab, either; plenty of people, called "biohackers," have taken it upon themselves to enhance natural human abilities.Some of this biohacking is limited to simple dieting fads like Bulletproof coffee, but others have taken it to the surgical level, implanting magnets in their fingertips, for example.Sounds like some crazy science fiction, but wetware — or human-implanted technology — isn't so strange.Technically, a pacemaker is wetware, and some might argue that even glasses count as wetware because they artificially boost your eyesight.Governments, including the United States, China and Russia, have been particularly interested in wetware and gene mutations to enhance human abilities to create super-soldiers.
