Mt. St. Helens
Back from the Dead

When Mount St. Helens erupted in 1980, every living thing in the blast zone was buried beneath 300 feet of avalanche debris, covered with steaming mud and, finally, topped with a superheated layer of frothy rock from deep within the earth.

Using GPS, magnetic mapping and more, geologists track the movement of magma deep within the volcano and reveal a hidden lattice of faults that lies beneath the volatile landscape. NOVA presents a pioneering look at the interplay between biology and geology that may help scientists predict future volcanic eruptions.

Crash of Flight 447

On June 1, 2009, Flight AF447, an Air France Airbus A330 flying from Rio de Janeiro to Paris, disappeared over the Atlantic Ocean, taking with it all 228 lives on board. How could a state-of-the-art airliner with elaborate electronic safety and navigation features and a faultless safety record simply vanish without a trace?

NOVA assembles a team of seasoned pilots, engineers and safety experts to examine the evidence that emerged in the weeks following this disaster. What led Flight 447's crew to fly straight into a towering thunderstorm? Using expert testimony, messages transmitted by the doomed plane's computer system and multi-layered CGI weather reconstructions, NOVA pieces together the events leading up to the catastrophe.

Venom: Nature's Killer

Venom scientists are in a race against time. Inside the bodies of many creatures, evolution has produced extremely toxic cocktails, all designed for one reason: to kill. It took millions of years to perfect these ultimate brews of proteins and peptides, and we have only just begun to discover their potential. Now, the race is on to collect and study them before the animals that produce them disappear. But how does venom do its deadly work?

NOVA reveals how venom causes the body to shut down, arteries to bleed uncontrollably and limbs to go black and die. But nature's most destructive and extreme poisons could contain the building blocks for a new generation of advanced drugs that could treat heart attack, stroke, diabetes, obesity and cancer.

Cold Case JFK

Fifty years later, what can science tell us about the Kennedy assassination—and the investigations that followed? The 1963 murder, in broad daylight in front of hundreds of witnesses, was a homicide investigator's best-case scenario. Yet somehow the JFK assassination became a forensic nightmare, plagued by mishandled evidence, a controversial autopsy and, incredibly, a prime suspect murdered while in police custody before he could be tried—all of it captured on film. Now, NOVA follows a group of experts trying to unravel the lingering mysteries of the assassination.

Wild Predator Invasion

A growing number of scientists are discovering that removing top predators from the wild has thrown ecosystems off-kilter, triggering domino effects that scientists are just beginning to understand. NOVA follows scientists who are trying out a simple but controversial solution: returning apex predators—like coyotes, bears and panthers—to their natural environments. Can these newly introduced predators restore the natural balance of their ecosystems without threatening the humans who live among them?
