Lab Notes: A New Class Brings CRISPR to the People

The announcement came in June. Berkeley Extension, the continuing education arm of UC Berkeley, was offering its first-ever introductory courseCRISPR Genome Editing: From Biology to Technology—on the revolutionary new tool that allows scientists to make precise edits in the genome. A lab and lecture course on CRISPR for anyone who has the interest (and money) to enroll? What a crazy idea. It seemed a bit like offering a workshop on how to enrich plutonium.

Meet CRISPR: Humanity’s Shiny New Tool

One of biology’s wilder facts is that we’re all family. You and me, sure, but also me and a mushroom. Triceratops shared genes with you. So does the virus that makes you cough, and a rosebush. Bacteria left us on the tree of life around 2.7 billion years ago, but the wet world they came from is still ours: One code runs all of life. The same proteins that imprint memories in your neurons, for example, do so in octopi, ravens, and sea slugs. This genetic conservation means tricks from one species can be hijacked. If you stick a jellyfish gene in a monkey, it’ll glow green.
