Why Animal Testing Is a Broken System and What's Replacing It with Mackensey Alexander | Ep19
from Puppies, Pandemics, and Public Health · host Dr. Johnny Lieberman
What if the biggest obstacle to curing Alzheimer's, ALS, and cancer isn't funding or effort, but the model we've been using for 2,000 years? Mackensey Alexander, bioethicist and law student at Lewis & Clark, makes the case that animal testing isn't just ethically wrong, it's scientifically broken. With a 90% failure rate in translating results to humans and $23 billion in taxpayer dollars spent annually on animal models, Mackensey and Dr. Lieberman break down the growing field of New Approach Methods (NAMs), from tumor organoids to organ-on-a-chip technology, and why the science of the future is already here. Plus: what's happening right now in Washington D.C. that could change everything.
