Genetically Engineering Almost Anything
A new technology just announced today has the potential to wipe out diseases, turn back evolutionary clocks, and reengineer entire ecosystems, for better or worse. Because of how deeply this could affect us all, the scientists behind it want to start a discussion now, before all the pieces come together over the next few months or years. This is a scientific discovery being played out in real time.

Today, researchers aren’t just dropping in new genes, they’re deftly adding, subtracting, and rewriting them using a series of tools that have become ever more versatile and easier to use. In the last few years, our ability to edit genomes has improved at a shockingly rapid clip. So rapid, in fact, that one of the easiest and most popular tools, known as CRISPR-Cas9, is just two years old. Researchers once spent months, even years, attempting to rewrite an organism’s DNA. Now they spend days.
