CRISPR Gene-Drive Tested on Mammals for the First Time in History

CRISPR gene drives have been tested in laboratory mice for the first time, offering a way in which multiple genes in mice can be altered to model complex multigenic human diseases. Could this step eventually lead to the eradication of pest species or is the technology still too controversial?

DNA Shed By Embryos Could Offer Non-Invasive Testing

A small pilot study presented at the European Society for Human Reproduction and Embryology 2018, suggest that DNA shed from early embryos could one day provide an alternative way of genetically testing them without having to do a biopsy.
