Produced by the American Geosciences Institute, this segment provides an overview of the biosphere and its components. Additional discussions include how humans are impacting the biosphere. Part of the "Visions of Earth" series.
This segment investigates the geosphere and its components, including plate tectonics, surface processes, and the rock cycle. It also discusses how geoscientists collect evidence to study past, present, and future changes by using computer-based technologies that model and monitor Earth’s systems and processes. Part of the "Visions of Earth" series.
Developed by the American Geosciences Institute, this segment provides an essential and well-tested tool for teaching and learning about the planet. Eight different scientists describe their field work and geoscience research. Part of the "Visions of Earth" series.
Drawing upon the American Geological Institute's huge geoscientific archive of information, this segment explores the hydrosphere and the atmosphere. It also covers their formation and components, the water cycle, geological evidence of past climate change, extreme weather, and the future of the fluid spheres. Part of the "Visions of Earth" series.
Proteins are the workhorses of cells. With support from the National Science Foundation, University of Arkansas biochemist James Hinton has been researching their structure and function for decades. Back in the 1990’s, he had a vision to study these huge protein structures in 3D and now, in cooperation with a company called Virtalis, his vision has become a reality. The new system allows researchers to enlarge the visual of a protein to room-size, so they can examine it from all angles, to better understand its structure and function. The new 3D visuals are also helping Hinton realize his other vision to better engage students in his discoveries and science in general.
What does detergent do? The scientists research its qualities with an experiment. In this chapter, they will also conduct experiments in 2D and 3D to determine how vision works with different dimensions. The scientists will also explain the phases of the moon. Part of the House of Science Series.
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.
Ancient primate progenitors had bodies a lot like those of modern monkeys and spent tens of millions of years living in trees. From them, humans inherited versatile hands, amazing vision, and capable brains. Part of the “Your Inner Fish” series.
Will robots replace humans? Revolutionary new machines are being designed and built for the workplace of tomorrow. Along with visiting robotic labs around the world, this production explores robot-human psychology and tests out an exoskeleton, a robot that you can strap on and wear.
Wildlife expert Casey Anderson takes on the task of tracking and filming one of North America’s most elusive predators, the mountain lion. He and his hounds set out to track a mountain lion hoping to study its anatomy and leaping ability. Part of the "Expedition Wild" series.
In 1990, when the first images from NASA's Hubble Space Telescope were too blurry to use, JPL scientists and engineers went to work to devise a fix. They created a camera with corrective vision to bring Hubble images into sharp focus. Part of the “Crazy Engineering” series.
What weighs 6,000 pounds, has poor vision, and a horn growing on its nose? A rhinoceros, of course! Solio Ranch in Kenya is a private wildlife sanctuary for black and white rhinos. Explains the differences and similarities between these animals, and notes poachers want only the rhino's horn for Asian and Middle Eastern markets. Shocking statistics emphasize the urgency to protect this unique species. NOTE: One brief mating scene.
Imagine robots no bigger than a fingertip scrambling through the rubble of a disaster site to search for victims or to assess damage. That’s the vision of engineer Sarah Bergbreiter and her research team at the University of Maryland. With support from the National Science Foundation (NSF), they’re building micro-robots to create legs that will ultimately allow a millimeter-scale robot to traverse rough terrain at high speeds. Part of the National Science Foundation Series “Science Nation.”
The eye is one of each human's major sense organs. It gathers light information and transforms it into a signal that is used by the brain to formulate an appropriate response. How does this process work? What are the structures involved, and what do they do? These questions are answered using a unique, integrated approach that combines the anatomy and function of the eye. Includes detailed footage of the dissection of the bovine eye.
How can honeybees communicate the locations of new food sources? Austrian biologist, Karl Von Frisch, devised an experiment to find out. By pairing the direction of the sun with the flow of gravity, honeybees are able to explain the distant locations of food by dancing. The scientists at Georgia Tech University explain the design of Von Frisch's famous experiment and describe the precise grammar of the honeybees dance language with new computer vision techniques. They hope the research into behaviors of social insects will aid in the design of better systems of autonomous robots.
Living green is something many of us strive for in today's world, but did you know that you can die green as well? Set in the foothills of the Appalachians, the film explores one man's vision of using green burials to conserve land. Dr. Billy Campbell, the town's only physician, has radically changed our understanding of burials in the United States. Dr. Campbell's dream is to conserve one million acres of land. This film focuses on the revolutionary idea of using our own death to fund land conservation and create wildlife preserves.
Students receive a crash course in the physiology and functioning of their hearts as well as how to keep their hearts healthy. Animations clarify how the heart works to provide oxygen and nutrients to all the tissues and organs of the body. They also detail what can go wrong. The program stresses that even teenagers can show early signs of atherosclerosis and other heart problems. Two cardiologists and a dietitian then pinpoint the main risk factors for an unhealthy heart, including: smoking, abnormal levels of cholesterol, high blood pressure, obesity, diabetes, and physical inactivity.
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.
The goal of this research is to determine the mechanisms underlying predatory and defensive behavior guided by an extraordinarily novel sensor in snakes. Pit vipers, pythons and boas possess special organs that form images in the brain of the thermal environment, much like vision occurs in the human brain. Thus, these snakes see heat, and this amazing system is the most sensitive infrared detector on Earth, natural or artificial. A better understanding of infrared-based thermal imaging in snakes is important not only for understanding complex behavior in these highly efficient predators, but also for understanding the evolution of imaging sensors and the behaviors they support in other animals including people. Part of the National Science Foundation Series “Science Nation.”
Most pet owners talk to their animals at one time or another, and some do every day. But, how much do pets actually understand? Is their perception anything like our own? These are the questions that fascinate Irene Pepperberg and she’s looking for answers from the animals themselves, specifically – African Grey Parrots. The Harvard psychology professor is a bit like the character Dr. Doolittle because she’s been talking to parrots for decades. With help from the National Science Foundation, she’s researching how much the birds understand about shapes, numbers, and colors. Her next phase of research involves how the parrots detect optical illusions, and whether they perceive them the way humans do. Her research will also reveal more about how a bird’s vision works.
