Fringe, and they're as vicious as ever. Two weeks ago mysterious killers used super-size cold viruses—and questionable science—to murder prominent epidemiologists, and in last night's episode, "The Transformation," a deadly virus turned its victims into unrecognizable monsters. The first victim is flying on a plane when the change starts as a nosebleed, and then kicks into high-gear when he convulses and huge spines shoot out of this back. Once the man becomes a half porcupine/half wolfman, he terrorizes the plane until it crashes. The Fringe team finds his body at the crash site, so mangled that rescue workers thought he was an animal, not a human.
According to lab analysis by Walter and Peter Bishop, the mad scientist and his son, the transformation is caused by a "designer virus" that completely re-wrote the victim's DNA, changing all the internal organs and turning him into a monster. Fringe gets at least one part of the case correct when Peter says, "this stuff doesn't exist in nature."

Could a Virus Rewrite Your DNA?But what about the genetics claim in "The Transformation," that the virus mutates the host's DNA to change its host into monsters? There is a speck of real science in there, says Harvard University virologist Donald Coen. Retroviruses, the class that includes HIV, use the DNA in their host cell to replicate, then leave behind their genetic information in the host. "There are lots of examples in animals," he says. And Coen says it is possible to manipulate retroviruses. Some scientists hope to use them as a vehicle to get genetic material into cells, he says, by piggybacking the useful material onto the virus and then allowing the virus to copy its genetic material into the cell.
However, that kind of research is in early stages, Coen says. And though Peter Bishop says during "The Transformation" that a person would need to know cutting-edge genetics to create the killer virus, Coen says the Fringe scenario is far past the real capabilities of current genetic engineering—no virus could rewrite your entire genetic code.
