Improved CRISPR gene drive solves problems of old tech (Cornell University, March 2020)

Gene drives use genetic engineering to create a desired mutation in a few individuals that then spreads via mating throughout a population in fewer than 10 generations. Now, a Cornell study, "A Toxin-Antidote CRISPR Gene Drive System for Regional Population Modification," published Feb. 27 in the journal Nature Communications, describes a new type of gene drive with the potential to delay resistance.
