Meet the biohacker who wants to teach everyone how to edit genes.

Josiah Zayner is a biohacker who thinks everyone should be able to change their DNA with biotechnology called CRISPR. That’s why he founded a company called The ODIN, which sells do-it-yourself biotech kits that teach people how to genetically modify bacteria and frogs. It's DIY gene therapy.

His company has sold tens of thousands of experiments using CRISPR, an inexpensive and precise gene-editing technology that has revolutionized the field.

Using a new imaging technique, researchers for the first time captured the process in which developing killer T-cells are tested by dendritic cells, and others, to see if they react to normal proteins from the body, called self-antigens
