The human embryo research controversy has once again been reopened after scientists made it public that they have finally lengthened the ability of a human embryo to survive beyond the authorized 14-day threshold.
The BioScience Talks podcast features discussions of topical issues related to the biological sciences. By altering the heritability of certain traits, gene drive technologies have the potential to spread desired genes through wild populations. In practice, this could lead to mosquito populations that, for example, bear traits making them resistant to the spread of malaria. Despite the huge potential for improving human well-being, concern exists that gene drives could fail in the wild or, perhaps more concerning, spread beyond their intended target populations.
