Orange-and-black wings fill the sky as NOVA charts one of nature's most remarkable phenomena: the epic migration of monarch butterflies across North America. To capture a butterfly's point of view, NOVA’s filmmakers used a helicopter, ultralight, and hot-air balloon for aerial views along the transcontinental route. This wondrous annual migration, which scientists are just beginning to fathom, is an endangered phenomenon that could dwindle to insignificance if the giant firs that the butterflies cling to during the winter disappear.

Once every 48 years, bamboo forests in parts of northeast India go into exuberant flower. Then, like clockwork, the flowering is invariably followed by a plague of black rats that appear to spring from nowhere to spread destruction and famine in their wake. For the first time on film, NOVA and National Geographic capture this rat population explosion in vivid detail and show how scientists are unraveling the connections between bamboo flowering and rat outbreaks. Ultimately, their research should help local people better cope with the next attack—due in 2056.

In collaboration with National Geographic, NOVA follows the exploits of acclaimed photojournalist James Balog and a scientific team as they deploy time-lapse cameras in risky, remote locations in the Alps and Arctic, including Alaska and Greenland. Grappling with blizzards, fickle technology, and climbs up craggy precipices, the team must anchor cameras capable of withstanding subzero temperatures and winds up to 170 miles per hour. In this high-action scientific adventure, NOVA and National Geographic investigate the mystery of the mighty ice sheets, whose still-unknown behavior will affect the fate of coastlines around the world.

What killed the mammoths? Near the end of the last ice age 13,000 years ago, these mighty beasts disappeared from North America together with some 35 other groups of mammals, including giant ground sloths, saber-tooth cats, and American lions. For four decades, debate has raged over the cause of their abrupt demise. In Last Extinction, NOVA presents an exclusive in-depth investigation of a bold and controversial new hypothesis, which suggests that a massive impact from space could be the culprit. According to the theory, an incoming comet broke up over North America in a devastating series of explosions, causing widespread forest fires and wiping out plants, animals, and prehistoric people. The evidence comes from a mysterious black mat layer discovered at more that fifty sites across the continent. The black mat contains exotic materials including rare microscopic nanodiamonds that are claimed to be the signature of an extraterrestrial impact. But other scholars question the evidence and argue that ancient hunters armed with a lethal stone weapon the Clovis spear point drove the giant beasts into oblivion. Still others believe the unstable climate at the end of the Ice Age was responsible. NOVA explores the dramatic new evidence of a cosmic explosion and the possibility that all three explanations may be correct.

In 1987, NOVA's cameras began rolling to chronicle the lives of seven young, bright medical students embarking on the longest and most rigorous endeavor in higher education: the years-long journey to become a doctor. From their first days at Harvard Medical School to the present day, none of them could have predicted what it would take, personally and professionally. In "Doctors' Diaries," a two-hour special, NOVA returns to find out what sorts of doctors—and people—the seven young students have become. The program is the latest installment in the longest-running U.S. documentary of its kind.

An exploration of the effect of music on the brain via four case studies from neurologist Oliver Sacks book "Musicopia" and the MRI visualizations from Sacks' own brain as classical music is played, including Bach's "Mass in B Minor." Study subjects include a man with Tourettes syndrome who has found relief while playing the drums; an autistic savant who is simply dazzling on the piano; a woman who suffers the inability to process music, known as amusia; and a surgeon whose life changed after being struck by lightning.

The best-known scientific instrument in history was dying. After nearly 20 years in space and hundreds of thousands of spectacular images, the Hubble Space Telescope's gyroscopes and sensors were failing, its batteries running down, and some of its instruments were already dead. The only hope to save Hubble was a mission so dangerous that in 2004 NASA cancelled it because it was considered too risky.

Though they may look like dragons and inspire stories of man-eating, fire-spitting monsters with long claws, razor-sharp teeth and muscular, whip-like tails, these creatures are actually monitor lizards, the largest lizards to walk the planet. With their acute intelligence — including the ability to plan — these lizards are a very different kind of reptile, blurring the line between reptiles and mammals. And even though these bizarre reptiles haven’t changed all that much since the dinosaurs, they are a successful species, versatile at adapting to all kinds of settings. “Lizard Kings” looks at what makes these tongued reptiles so similar to mammals and what has allowed them to become such unique survivors. But while the creatures can find their way around many different habitats, finding them is no easy task. Natural loners, and always on guard, they sense anything or anyone from hundreds of feet away. NOVA follows expert lizard hunter Dr. Eric Pianka as he tracks the elusive creatures through Australia’s heartland with cutting-edge “lizard cam” technology for an unparalleled close encounter with these versatile “living dragons.”

NOVA takes viewers on a journey from the Galapagos Islands to the Arctic, and from the Cambrian explosion of animal forms half a billion years ago to the research labs of today. Here scientists are finally beginning to crack nature’s biggest secrets at the genetic level. And, as NOVA shows in this absorbing detective story, the results are confirming the brilliance of Darwin’s insights while exposing clues to life’s breathtaking diversity in ways the great naturalist could scarcely have imagined.
