Join hosts Dr. Liza Dunn and GLP contributor Cameron English on episode 258 of Science Facts and Fallacies as they break down these latest news stories:
Advances in gene therapy are now enabling physicians to treat, and maybe even cure, lifelong disabilities like deafness. But as these novel therapies enter the market, they’re making enemies in the very communities they’re designed to help. For example, some deaf people oppose a gene-editing procedure that could restore hearing in young children who would otherwise go through life in complete silence. Deafness isn’t a medical condition in need of treatment, they argue, but an identity that should be preserved and respected. How do we walk the fine ethical line between treating patients we can help and protecting the autonomy of people who say they don’t need medicine?
As our knowledge of genetics improves, scientists are beginning to screen embryos before they’re implanted in hopes of identifying the ones who may be susceptible to serious diseases later in life. The upside is unmistakable: parents could significantly increase their child’s odds of leading a healthy life before they’re even born. But embryo screening may carry serious ethical risks we’re not yet prepared to address. For instance, what do we do when parents want to use embryo screening to increase the chances that they will have a deaf child? Who’s to say such a desire is wrong? These questions illustrate the complex issues we have to tackle before this technology is fully deployed.
A handful of states are considering legislation that would effectively outlaw lab-grown meat products. Such restrictions are sometimes justified on the grounds that growing meat in a lab, as opposed to harvesting it from slaughtered animals, could pose a public health risk. Critics of the proposed bans say they are little more than a handout to the agriculture industry, a disingenuous way to protect it from competition. Who has the upper hand in this debate?
