"In the last five years, biology has undergone a seismic shift as researchers around the globe have embraced a revolutionary technology called gene editing. It involves the precise cutting and pasting of DNA by specialized proteins—inspired by nature, engineered by researchers. These proteins come in three varieties, all known by their somewhat clumsy acronyms: ZFNs, TALENs, and CRISPRs. But it’s CRISPR with its elegant design and simple cell delivery, that’s most captured the imagination of scientists."
From Wired Magazine, everything you need to know about how scientists can repurpose a bacterial immune system to alter DNA, making everything from cheap insulin to extra starchy corn.
