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.

As scientists delved deep into the atom, into the very heart of matter, they unraveled nature's most shocking secrets. They had to abandon everything they believed in and create a whole new science, which today underpins the whole of physics, chemistry, biology, and maybe even life itself. Tells a story of great geniuses, like Albert Einstein and Werner Heisenberg who were driven by their thirst for knowledge and glory. It's a story of false starts and conflicts, ambition, and revelation, a story which leads us through some of the most exciting and exhilarating ideas ever conceived of by the human race.
Human beings, like every living organism, are driven by two inherent needs: to survive, and ultimately, to reproduce. To accomplish the goals of survival and reproduction, we have inherited bodies crafted by evolution so that every individual human organism is an organic super factory, a living machine made up of systems that process fuel, build products, repair damage, expel waste, and defend against invaders. Introduces the complex physiological systems of the human body: muscular movement, digestion, circulation, respiration, nerves, glands, immunity, and reproduction. Also, illustrates and explains the cellular basis of life and the importance of carbon in organic chemistry.
To what degree are we genetically programmed with certain traits and abilities? Looks at recent technologies and scientific discoveries and considers the classic "nature versus nurture" discussion. Segments cover identical twins, the science of biotechnology, and the genetic inheritance of working dogs. Investigates the similarities in personality shared by identical twins. Explains how recent breakthroughs in genetics research and DNA have created new ways to solve crimes, breed (clone) animals, and extend human life. Discusses cross-species cloning, human cloning, and gene therapy. Shows how assistance and search-and-rescue dogs can be taught to overcome their inborn instincts and fear.
In the dark recesses of a warehouse, a drunken game of cards explodes into a murder. Now the night watchman lays dead. The only witnesses are a housefly or perhaps a cockroach that might be skittering by. That stylized tribute to our seemingly endless appetite for TV programs about forensic science sets the stage for an examination of how, in the real world of police investigations, nature is being enlisted in the war on crime. Sifts through the mayhem, murder, and science that make up the world of forensic investigation with the help of Dr. Jennifer Gardy, of British Columbia's Centre for Disease Control (CDC).
In some parts of the world, there is an intimate connection between the infectious parasitic disease "malaria" and the genetic disease "sickle-cell anemia." A keenly observant young man named Tony Allison, working in East Africa in the 1950s, first noticed the connection and assembled the pieces of the puzzle. His story stands as the first and one of the best understood examples of natural selection, where the selective agent, adaptive mutation, and molecule involved are known--and this is in humans to boot. The protection against malaria by the sickle-cell mutation shows how evolution does not necessarily result in the best solution imaginable but proceeds by whatever means are available.
Explores the need for many multicellular plants to have specialized internal transport systems, which are systems that can efficiently distribute materials from soil and leaves to the parts of the plants where they are needed. An overview of how plants obtain their nutrients is provided. The structure and function of root hairs is explored, explaining their remarkable ability to facilitate an enormous uptake of water and dissolved minerals for the plant. Following this, the separate transport systems of the xylem and phloem are explored in detail. Also explains the mechanisms by which vascular plants transport water and minerals upward from the roots as well as sugars from leaves and other sugar sources throughout the plant for storage or for growth and repair.
Harvard University, electrical engineers Rob Wood and Gu-Yeon Wei, and computer scientist Radhika Nagpal created the “RoboBee,” a miniature flying robot, inspired by the biology of a bee and the insect’s hive behavior. With support from the National Science Foundation and a program called Expeditions in Computing, Wood put together a diverse team of collaborators to get the RoboBee project off the ground. Ultimately, the researchers hope to build a colony in which the RoboBees interact, using their hive as a refueling station. They say RoboBees have the potential to be useful in a number of ways, including search and rescue missions, traffic monitoring, and weather mapping.

The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Flora Whiff, the famous expert on smell, comes to school to judge the First Annual Smell Search. Ms. Frizzle's class creates a unique smell which is bound to take first prize, but Arnold's cousin, Janet, determined to win by herself, changes their smell to an odor only a skunk could love. The kids discover the secret to what makes things smell. Now they have to make sure their creation doesn't make a big stink.
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.
The rock pocket mouse is a living example of Darwin’s process of natural selection. Not only is evolution happening right now everywhere around us, but adaptive changes can occur in a population with remarkable speed. This speed is essential if you’re a desert mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. The film features Dr. Michael Nachman, whose work in the field and in the lab has quantified the selective pressure of predators and identified the genes involved in adaptation. In a complete story, from ecosystem to molecules, pocket mice show us how random changes in the genome can take many paths to the same adaptation—a colored coat that hides them from predators.
University of Pennsylvania ecologist Peter Petraitis, California State Northridge biologist Steve Dudgeon, and their team have been returning to Maine’s rocky intertidal zone every spring and summer for nearly two decades. With support from the National Science Foundation (NSF), they survey a network of 60 experimental plots. The big question that brings them back year after year: Is an ecosystem like this a stable and permanent fixture, or, under harsh conditions, could it reach a tipping point? The idea is that changes in conditions could cause a switch from one community to another, such as from mussel beds to rockweed, and then back again. Part of the National Science Foundation Series “Science Nation.”

The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Ralphie wants to catch salmon to serve at the annual school picnic, but he can't find any at his favorite fishing spot. Where could all the salmon have gone? The kids are soon "Frizzled" inside a salmon bus that has an uncontrollable urge to head upriver. Using its sense of taste and smell, it swims the long journey to a shallow freshwater stream mile away. Why has the bus, which thinks it's a salmon, gone to all this trouble?
An introduction to sign vocabulary that is specific to science. Many interpreters, teachers, and students are unfamiliar with specialized sign vocabulary because the concepts occur infrequently in daily communication. In this video a Deaf professional signs vocabulary related to his field of expertise. The signs being demonstrated are commonly accepted by the Deaf community, but may not be the only sign for a specific word. Signs often vary across the country, so viewers are encouraged to confirm that signs used in this video are those used in their area/region of the country. Where appropriate, more than one sign or combinations of signs are demonstrated in this video for the same English word.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. When Phoebe tries to grow a big vine for her school's production of Jack and the Beanstalk, all she ends up with is a stunted little sprout. To help out, Ms. Frizzle turns her into a real vine. But to grow tall, Phoebe needs to figure out how plants eat. To unearth the amazing ways plants make their own food, Ms. Frizzle and the kids shrink down and dig deep in a quest to root out the facts.
At the twilight of an active life, Anna is now bedridden due to a serious fall. What makes the elderly--even those who are in full possession of their mental and physical faculties--more prone to falling than younger people? As this program demonstrates, the answer lies not in the body or the brain alone, but in their interconnection. Exploring Anna's past dreams of becoming a ballerina, the film shows how complex physical motion, such as dancing or even typing, requires sophisticated coordination between the body's neural, muscular, and skeletal systems. How aging affects such coordination and how new artificial limb technology enables movement are running themes in the program.
