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.

Provides a short overview of the five senses: sight, hearing, touch, smell, and taste. Explores the special relationship between taste and smell. Shows how our senses combine to help us more richly experience the world around us. Includes suggested classroom activity.
Explains the names and functions of different parts of the human eye. Shows how the eyes and brain work together to see color and light. Tells how tears help keep eyes clean and healthy. Describes ways that a person's age affects their sight.
Hanna and Olli follow a mushroom that is racing to see a very rare sight. They are led through mile after mile of forest to the ancient and sacred Oak, but they fall asleep before they witness an amazing transformation. Part of the "My Little Planet" series.
Watch the story of how gene therapy restored the sight of a nearly-blind young patient. Told from the perspective of two researchers who spent over 25 years working to develop this breakthrough technology, this short film chronicles their successes and challenges, and illustrates how the method works to treat inherited conditions.
Josh Landis and Mitch Butler discuss metamaterials, a type of nanotechnology. These materials can theoretically make objects disappear from plain sight. This cloaking technology has a wide range of applications and could forever change the view of the world. Part of the Fast Draw Series.
Explores how eyes work and how eyes help us understand the world. Explains how safe behaviors and healthy habits can prevent illness and injury to eyes. Discusses what to expect from an eye examination and other eye tests. Talks about how visually impaired children walk with a white cane and read Braille.
Find out how Albert Einstein used the totality phase of the 1919 solar eclipse to prove his theory of relativity, which predicts that large objects bend “space-time” towards themselves.
Charles Darwin’s father wants him to be a pastor, but Darwin has a passion for science. At the encouraging of his uncle, he boards a Royal Navy ship known as the HMS Beagle. The voyage lasts for five years, and Darwin’s discoveries will revolutionize science. During the voyage, he spends most of his time on land performing methodical observations, which lead to his theories on evolution and natural selection. Part of the “Butterfly Effect” series.
This national monument tells the story of the California’s Sierra Nevada Mountain Range. Established in 1911 by presidential proclamation, Devils Postpile National Monument protects and preserves the Devils Postpile formation, the 101-foot high Rainbow Falls, and pristine mountain scenery. The formation is a rare sight in the geologic world and ranks as one of the world's finest examples of columnar basalt. Its columns tower 60 feet high and display an unusual symmetry.
I think what your eyesight does is confirm other senses, says James Robertshaw, a world champion kite flyer and for two years personal assistant to Rory Heap. Heap has been blind from birth, but with Robertshaw's assistance pursues his ambition for kite flying--particularly of complicated figure eight patterns. Using all of his senses except for sight, Heap learns how to fly a kite with the same dexterity that Robertshaw uses to guide him through busy city streets.
In the 1950's, the Soviets decide to turn the vast desert steppes of Kazakhstan and Uzbekistan into fields of cotton and wheat. They diverted some of the rivers that feed the lake to irrigate the new crops. This depleted the Aral Sea, and in 1987, the level of the water falls so low that the sea splits into two bodies of water. It splits again in 2002. In 2014, the eastern part of the Aral Sea disappears forever, which causes an ecological disaster. Part of the "Butterfly Effect" series.
Touch, taste, smell, hearing, and sight: the human body's five major senses. They are senses that have evolved independently over millions of years but are brought together by our marvelous central nervous system into the most refined way of interacting with the environment of any species on the planet. Join Dr. Mark Reisman as he provides you with a look at the anatomy and physiology of each of these sensory systems and shows how the brain uses them to produce what we call being human.
Kathy Blake is blind but two years ago she got a glimmer of hope. She heard about an artificial retina being developed by a company called Second Sight and the Doheny Eye Institute in Los Angeles. It was experimental, but Kathy was the perfect candidate. With funding from the National Science Foundation, a camera is built into a pair of glasses, sending radio signals to a tiny chip in the back of the retina. The chip, small enough to fit on a fingertip, is implanted surgically and stimulates nerves that lead to the vision center of the brain.
Sight, touch, hearing, taste, and smell send sensory messages to the brain at a speed of 430km/hr. The brain deals with 11 million information signals per second, and this continual flow of information is sorted and analyzed by the brain, which directs the senses, organizes them, and improves them. The brain’s plasticity allows it to continually adapt. If and individual loses one sense, the brain reorganizes and compensates by increasing the power of the other senses. This episode highlights an artist who is blind and uses his fingers to feel the color of the paint before applying it to the canvas. Part of the “Human + The Future of Our Senses” series.
As shown on the History Channel. The single longest linear feature on Earth--the "Ring of Fire" circles almost the entire Pacific. It is a ring of active volcanoes from White Island just north of New Zealand, through the South China seas, Japan, Kamchatka, the Aleutians, the Cascades and down through the Andes. Almost 25,000 miles long, it is one of the most awesome sights on Earth.
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, Mei-Lei takes Moko to the rice fields. The sky is blue and Moko thinks that in this country there just aren't any clouds. Mei-Lei tells him to wait until nightfall, that the rains will dance over the village. Moko doesn't believe her, there isn't a cloud in sight! Suddenly, the sky darkens and Mei-Lei wants to return to the village, but Moko wants to know more. He climbs the hill behind the village to get a better look at the sky. The wind picks up and a great wave of rain washes everything in its wake. Moko and Mei-Lei take shelter from the monsoon behind a rock. To make the rain stop Mei-Lei starts to sing and dance. Bit by bit the rain subsides and the two friends decide to return to the village. Moko thinks that Mei-Lei's dancing was magical and had the power to stop the rain.
