Could an alien organism really survive a centuries-long trip on a meteor and remain virulent enough to attack a human being? How would a scientist know she was peering at a microbe from another planet? What's the possibility of a genetically mutated monster actually developing? In a gripping exploration of the facts behind the science fiction that has enthralled millions of X-philes, Anne Simon -- the respected virologist who comes up with the science for many intriguing episodes -- discusses telomeres, cloning, the Hayflick limit, nanotechnology, endosymbionts, lentiviruses, and other strange phenomena that have challenged the intellect and threatened the lives and sanity of America's favorite FBI agents. With Simon's extraordinary gift for explaining complicated, cutting-edge science in a light, accessible style, and her behind-the-scenes commentary on the development of various plot lines, The Real Science Behind the X-Files will appeal to science buffs and X-Files aficionados alike.
