Deep in Southern Mexico's jungle, the Villa Luz limestone caves support an ecosystem that thrives in a highly poisonous, acidic environment. This rare type of cave is found in few spots on Earth. Geologists and biologists wear gas masks and protective outerwear to explore the caves. All life forms, from microbial colonies to spiders, fish and bats, are interdependent upon the toxic soup of water, sulphur-oxide and hydrogen monoxide for survival.

What do wild animals do when we're not around? Find out with National Geographic's Crittercam. Safely worn by wildlife, Crittercams capture video, sound, and other information, giving students rare views of the private lives of animals. Crittercams help to solve scientific mysteries by providing an animal's eye view. And what scientists learn from Crittercams helps them protect the very animals that wear them. The Crittercam Team travels to Shark Bay hoping to discover why there are a larger number of injured loggerhead turtles than green turtles.
In 1936, Ruth Harkness, a dressmaker from New York, set off to China in search of the rare, elusive giant panda. Her goal was to bring one back alive to New York. She wanted to share the wonder of China's wildlife with the western world. She became the first explorer to do so, and set in motion a public fascination with these creatures that continues 80 years later. Part of "The Brain Scoop" series.
Iridium is a rare element used to light up cell phones and TVs. However, researchers have found a way to use a more common element to power electrical devices: copper. Researchers are also developing a better treatment for osteoarthritis through nanotechnology. Other segments include research into specialized metabolites and devices that translate sign language. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.

Professor Lawrence Gilbert and his team at the University of Texas at Austin have discovered a population of tropical butterflies that exemplify "evolution in action," and a rare research opportunity. Gilbert says they may be witnessing a species of butterfly splitting into two different species. The stars of this research are the Heliconius butterflies, found in Central and South America. Despite the genetic similarities between the two groups of the butterflies, one group is showing a color preference during mating. With support from the National Science Foundation, Gilbert and his team are working to gain insights about genetics, behavior, ecology, and evolution.
The science of sight has entered a new era. Scientists are starting to understand how a few rare individuals can see better or see faster. Meet a woman who can see a hundred more colors than the average human being, and a heavyweight boxer who undergoes sophisticated training to increase the speed of his visual reflexes and acuity. As silicon and carbon meld and point the way to a bionic future, researchers discuss how technology is starting to replace or enhance vision for those who have lost it. Viewers witness the moment when a husband and father, equipped with an experimental retinal implant, sees his wife and child for the first time. Part of the “Human + The Future of Our Senses” series.
It's gang warfare when Africa's meerkats face danger. Wild Chronicles heads to Africa's Kalahari Desert where researchers studying a band of young meerkats find they rarely face danger alone. Segment of video from Wild Chronicles.
The first in a series of five documentaries plots the course of the river, from its source to its delta. In a succession of spectacular images we see the extraordinary geographical route that the Mekong takes, from the Tibetan plateau, down the mountains of the Yunnan Province in China, then through the tropical valleys and virgin forests of Burma, Cambodia, Laos and Thailand before reaching the green plains of Vietnam. In the tropical forest, nature abounds with wild animal species, rare plants and flowers. In Laos', whole villages still pray to the Gods of Trees while in Thailand a hunter shows how the hunting of Asian elephants for preservation, now forbidden, was practiced.

Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko had gone to see his friend, the wise old man who lives on the other side of the village. There were such pretty flowers that Moko could spend the entire day contemplating them. The old man picked a beautiful rose and handed it to Moko. But on the way back, the sun was so hot that the flower began to wilt. Moko was so sad that he laid the withered rose on the ground and started to cry. The wind rose, sweeping across the ground. Moko then saw that his rose was still there, more beautiful than ever and sparkling, its petals solid as stone. It had become a desert rose, as rare as water in the desert.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, one morning, Totemie takes Moko to pick wild mushrooms used for medicine by her people. There is a particularly rare one she is hoping to find. Moko suddenly slips in a crevice. Totemie runs to her village to get an old man who tells her that she should join Moko. When she does, Moko and Totemie discover an enormous cave filled with lakes in a rainbow of colors. They follow a stream that eventually becomes a river and on the river's bank they find the old man who is waiting for them. Before they leave to go back to the village, the old man asks them to keep this magical cave a secret and to keep the memory of it safe in their mind.

Meet Boss – the car that can drive itself. Boss is the invention of Carnegie Mellon researcher Raj Rajkumar and his team. It has 18 sensors, including a three dimensional laser and onboard computers that connect to GPS and mapping software. When it comes to knowing the rules of the road, Boss rarely makes a mistake. With support from the National Science Foundation, it was built for a Department of Defense competition called the DARPA Urban Challenge. Boss negotiated the roads, including traffic, and was the hands down winner in 2007.
James Watson and Francis Crick collected and interpreted key evidence to determine that DNA molecules take the shape of a twisted ladder—a double helix. The film presents the challenges, false starts, and eventual success of their bold chase. Watson relates what those early days in the Cavendish Laboratory were like, including his friendship with Crick and their shared ambition and passion. Rarely seen archival footage is combined with interviews with some of today’s leading scientists to bring this landmark discovery and all of its implications to life.
Humans construct boundaries around homes, neighborhoods, and nations to bring order to a chaotic world. However, they rarely consider how these boundaries affect the environment or others. Photographer Krista Schlyer and biologist Jon Beckman study how fabricated barriers influence the movement of wildlife. Schlyer and Beckmann have seen the damaging impacts resulting from the wall built along the Mexico-United States border. Humans probably will not stop constructing walls and fences any time soon, but planning the boundaries with wildlife in mind can help prevent these structures from causing environmental harm.
