Oops! Gene editing not as precise as advertised

By Kurt Cobb, Resource Insights

Sometimes a headline gives you practically the entire story. Take this one: "Gene-Editing Unintentionally Adds Bovine DNA, Goat DNA, and Bacterial DNA, Mouse Researchers Find."

CRISPR-Cas9 is a customizable tool that lets scientists cut and insert small pieces of DNA at precise areas along a DNA strand. The tool is composed of two basic parts: the Cas9 protein, which acts like the wrench, and the specific RNA guides, CRISPRs, which act as the set of different socket heads. These guides direct the Cas9 protein to the correct gene, or area on the DNA strand, that controls a particular trait. This lets scientists study our genes in a specific, targeted way and in real-time (2015). Author: Ernesto del Aguila III, NHGRI. Via Wikimedia Commons.

Genes, synecdoche and the possibility of editing ourselves

By Kurt Cobb, Resource Insights

Writers have previously imagined the dangers of such a moment, but now the democratization of genetic engineering is at hand. The dangers stem in part from our not understanding that we are mistaking a part for the whole. Humans are not just their genes.
