Australia's First 4 Billion Years: Strange Creatures
Wednesday, May 1 at 9pm
After the asteroid impact 65 million years ago — believed to have wiped out the dinosaurs — Australia was set adrift on a lonely voyage in southern seas. With host Richard Smith at the wheel, NOVA travels this walkabout continent to uncover how it became the strange island it is today. Australia’s many unusual creatures, like the kangaroo and the cassowary, tell a tale of isolation, change and resilience. Australia’s long history has seen mountains rise and fall, seas come and go, and whole kingdoms of life triumph and disappear. In this final episode, NOVA races down the last 65 million years to the present day.
Venom: Nature's Killer
Wednesday, May 8 at 9pm
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. “Venom” follows two scientists on their expeditions to track down and capture the planet’s most deadly creatures, risking life and limb just to tease out milligrams of venom and get it back to the lab. Find out how nature’s deadliest cocktails could be medicine’s brightest new hope.
Secrets of the Sun
Wednesday, May 22 at 9pm
It contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the sun as they never have before and even re-creating in labs what happens at the very center of the sun. Their work will helps us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications and ground global air travel for days, weeks, even longer. Such storms have occurred before — but never in the modern era of satellite communication. "Secrets of the Sun" reveals a bright new dawn in our understanding of our nearest star — one that might help keep our planet from going dark.
Manhunt - Boston Bombers
Wednesday, May 29 at 9pm
At 2:50 p.m. on April 15, two bomb blasts turned the Boston Marathon finish line from a scene of triumph to tragedy, leaving three dead, hundreds injured and a city gripped by heartbreak and terror. Less than five days later, the key suspects were identified and apprehended, with one dead, the other in custody. How did investigators transform the chaos of the bombing into a coherent trail of clues, pointing to the accused killers? NOVA follows the manhunt step-by-step, examining the role modern technology — combined with old-fashioned detective work — played in cracking the case. Given hundreds of hours of surveillance and bystander videos, how did agents spot the bad guys in a sea of spectators? Why couldn’t facial recognition software I.D. the criminals? How much could bomb chemistry analysis, cell phone GPS, infrared imagery and crowd sourcing reveal about the secrets behind this horrific crime? With the help of top criminal investigators and anti-terrorism experts, NOVA explores which technological innovations worked — and which didn't — in the most notorious case of today, and how the world of crime fighting could be transformed tomorrow.
