What if our genetic code could be re-written as easily as spell checking a Word document? That science-fiction daydream became reality with the 2012 discovery of CRISPR-Cas9, a gene-editing technique that holds the promise of eradicating disease, growing healthier foods, and bringing extinct species back to life.

And whether woolly mammoths are making a comeback.
