The science of fear
In a year that’s felt like a never-ending horror movie, some might actually find relief in watching thrillers on-screen this Halloween. But why is it that some people love all things spooky on screen while others can only watch through parted fingers? What makes horror films so scary yet so alluring? And does our fascination with horror media actually help us cope with the horrors of real life? Host Dr. Alok Patel zeros in on the science of fear, enlisting the expert guidance of a horror researcher, a neuroscientist, and the Emmy-winning Foley artist behind the tantalizing and terrorizing sounds in movies and shows like Invisible Man and Monsterland.Learn more about NOVA and subscribe to our YouTube channel.

Science in the courtroom
With confirmation hearings set to begin for Judge Amy Coney Barrett to join the Supreme Court, we ask the question that senators probably won’t: Do judges also need to be scientists? Science may not be the first thing that comes to mind when thinking of the U.S. court system, but everything from criminal cases’ forensic evidence to intellectual property disputes involve it. Host Dr. Alok Patel goes straight to the source for answers, speaking with a sitting federal judge and a lawyer who has worked on many Supreme Court cases.Learn more about NOVA and subscribe to our YouTube channel.

Rising health risks from West Coast wildfires
It's wildfire season—and something about this year is especially sinister. West Coasters experienced days of hazy orange skies in early September as a result of the burning wildfires. As COVID-19 still looms, threatening our respiratory systems, now too does the smoke in the air. What is this smoke made of, and how does breathing it in affect our lungs and bodies? To find out, Host Dr. Alok Patel speaks with an atmospheric scientist, a pulmonologist, and a pair of veteran engineers who are experts in effective face masks to learn about the composition of wildfire smoke, what that smoke does to our lungs and bodies, and what we can do to protect ourselves.Learn more about NOVA and subscribe to our YouTube channel.

Enter CRISPR, a gene-editing tool that can also be used to identify viruses. Host Dr. Alok Patel follows the story of the two scientists who first discovered this potential for battling the coronavirus, and the biotech company that hopes to use it to revolutionize modern diagnostics.
