Dr. George Church is a real-life Dr. Frankenstein. The inventor of CRISPR and one of the minds behind the Human Genome Project is no longer content just reading and editing DNA -- now he wants to make new life. In Ben Mezrich's latest book, Wooly: The True Story of the Quest to Revive One of History's Most Iconic Extinct Creatures, Church and his Harvard lab try to do the impossible, and clone an extinct Woolly mammoth back into existence.
