On Friday's show: Researchers the University of Houston have developed a vaccine targeting the dangerous synthetic opioid fentanyl that could block its ability to enter the brain. We learn more about the breakthrough discovery and what it could mean for the opioid epidemic.

Also this hour: We discuss how climate change could create a new refugee crisis and the role Houston could play in that, since it’s already a hub for resettling refugees.

Then, we break down The Good, The Bad, and The Ugly of the week.

And Cat Daddies, a documentary about men and their cats, opens in Houston today. We talk with director Mye Hoang.
