Prominent genetic “biohacker” Josiah Zayner is under investigation by California state officials for practicing medicine without a license.
Zayner has a background in biophysics and runs a company called The Odin, which sells do-it-yourself genetic engineering kits and other lab equipment intended for use outside of scientific laboratories. The kits and tools are intended to allow lay users to genetically modify bacteria, yeast, animals, and even humans.
The human that Zayner’s products are best known for trying to modify is Zayner himself. In fact, the brazen CEO has a long history of self-experimentation. In 2016, he attempted a stomach-churning DIY fecal transplant in an airport hotel, then moved on to trying to genetically engineer his skin.
