Whether you've ever been curious about the microscopic world of organisms living inside you or wanted a deeper understanding of the science of addiction, get ready: The subject of this collection is “Health and Medicine.”

Addiction (2018)

Hear firsthand from individuals struggling with addiction and follow the cutting-edge work of doctors and scientists as they investigate why addiction is not a moral failing, but a chronic, treatable medical condition. Easy access to drugs like heroin, fentanyl, and even prescription medications like OxyContin has fueled an epidemic of addiction — the deadliest in U.S. history. Now, science is revealing how addiction affects the brain, and top experts are gathering evidence about how we should address our drug problem, from embracing evidence-based treatments, to rethinking public policies.

Poisoned Water (2017)

Water. Turn on the faucet and it’s always there. Without it we perish. But how safe is our tap water?

In this special report narrated by Joe Morton, NOVA investigates what happened in Flint, Michigan, when local officials changed the city’s water source to save money, but overlooked a critical treatment process. As the water pipes corroded, lead leached into the system, exposing the community — including thousands of children — to dangerous levels of poison. NOVA uncovers the science behind this manmade disaster — from the intricacies of water chemistry to the biology of lead poisoning to the misuse of science itself. NOVA follows ordinary citizens and independent scientists who exposed the danger lurking in Flint’s water and confronted those who turned a blind eye. And discover the disturbing truth that reaches far beyond Flint: water systems across the country are similarly vulnerable. How can we protect ourselves from poisoned water?

Vaccines – Calling the Shots (2014)

Diseases that were largely eradicated in the United States a generation ago — whooping cough, measles, mumps — are returning, in part because nervous parents are skipping their children's shots. NOVA's "Vaccines— Calling the Shots" takes viewers around the world to track epidemics, explore the science behind vaccinations, hear from parents wrestling with vaccine-related questions, and shed light on the risks of opting out.

NOVA Wonders: What's Living in You? (2018)

Whether they make you fat, fart, or freak out, microbes play a central role in your life.

Right beneath your nose — on your face, in your gut, and everywhere in between — trillions of bacteria, viruses, and fungi are so abundant in your body, they outnumber your human cells. But these aren’t just nasty hitch-hikers. Many are crucial to your survival. Evidence suggests that a diverse microbiome can keep you healthy and, conversely, a damaged one could kill you. NOVA Wonders peers into this microscopic world to discover the fascinating, bizarre, and downright surprising secrets of the human microbiome, including the world’s largest stool bank, which transforms raw stool into life-saving poop pills.

Life's Greatest Miracle (2001)

A sequel to one of the most popular NOVAs of all time, "Miracle of Life," this Emmy Award-winning program tracks human development from embryo to newborn using the extraordinary microimagery of Swedish photographer Lennart Nilsson.
