Communication between people and cultures initially stemmed from trade and commerce. With Guttenberg's invention of the printing press, information was available to people beyond the elite and wealthy for the first time. Trade drew explorers out into the oceans, and mapmakers outlined their treacherous journeys. These basic maps are what led Columbus to believe he could reach the East by sailing west. Instead he found America, and established trade routes between America and Europe.

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.
While the human brain and nervous system are wired with hundreds of billions of nerve cells, or neurons, sea slugs can get by with tens of thousands. Ironically, sea slugs reveal a lot about the chemistry of the human brain and nervous system. In fact, they are ideal as study subjects for research on learning, memory, and how neurons control behavior. With support from the National Science Foundation, analytical chemist Jonathan Sweedler and his team at the University of Illinois are working to develop new measurement tools that enable insights into the function of individual cells in the central nervous systems of slugs and other animals in order to uncover novel neurochemical pathways. Part of the National Science Foundation Series “Science Nation.”
This program explores how arthropod biodiversity helps humans. Insects are both producers and decomposers, and these functions are essential to the health of the planet. Part of the "Backyard Bugs & Other Arthropods" series.
With support from the National Science Foundation, mechanical and computer engineer Nilanjan Sarkar and psychologist Zachary Warren at Vanderbilt University have developed a learning environment for kids with autism, built around state-of-the-art technologies. One of those state-of-the-art technologies is a humanoid robot, nicknamed Russell, who works with the children on their ability to imitate others. The robot has some of the characteristics of a human, but it’s not as complex, so it doesn’t overstimulate or overwhelm a child with autism.
It has been 40 years since they've been seen with any regularity in the US, and jaguars have recently been spotted crossing the US-Mexico border. This is good news to conservationists working to create a permanent home in the feline's native range - a corridor that stretches from Mexico to Argentina. Segment of video from Wild Chronicles Series.
Scientist He Jiankui will likely go down in history as the first human to genetically engineer another living person. In this segment, host Trace Dominguez talks with Hank Green about the science and ethical issues of genetically altering humans. Part of the "Uno Dos of Trace" series.
At the National Science Foundation-funded Center for Environmental Implications of Nanotechnology (CEINT), headquartered at Duke University, scientists and engineers are researching how nanoscale materials affect living things. One of CEINT's main goals is to develop tools that can help assess possible risks to human health and the environment. A key aspect of this research happens in mesocosms, which are outdoor experiments that simulate the natural environment. These simulated wetlands in Duke Forest serve as a test bed for exploring how nanomaterials move through an ecosystem and impact living things. Part of the “Science Nation” series.
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.
StormView™ is a software program that gauges how residents of hurricane-prone regions might react in the event of an imminent storm. It was developed by University of Miami professor Kenny Broad and a number of collaborators, and supported with funding from the National Science Foundation and the National Oceanic and Atmospheric Administration. It includes TV meteorologist broadcasts, newspaper stories, web stories, bulletins from NOAA and even interactions with neighbors. The StormView™ simulation provides a way for social scientists to collaborate with meteorologists to tailor more effective messages. Part of the National Science Foundation Series “Science Nation.”

In the late 1950s, a skeleton was discovered in a cave in Iraq that drove scientists to rethink what it means to be human. It was on of at least 9 sets of remains of Neandertals and was named Shanidar 1. The discoveries made about Shanidar 1 reveal that the Neadertals might not have been as primitive as originally thought. Part of the "Eons" series.
Animals have contributed to scientific advancements, but how ethical is it to use them in research? Viewers explore the legal and ethical issues concerning the use of animals in research. Part of the "Core Concepts in Psychology" series.
Where do bacteria live, and how long have they been here? How can you tell them apart? What do they do to people and the environment? Answers these and other questions in this overview. Examines the fundamental structure of the bacteria cell, types of bacteria, and their importance to humans and the environment.
Explains what is normal for boys and girls at puberty: the biological facts of physical maturation, the timeline for growth for both sexes, the normal feelings of self-consciousness, the need for good personal hygiene, why mood swings happen, and preparation of the body for human sexuality and reproduction.
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 Palo Alto Humane Society tells the story of a compassionate and caring community that rides to the rescue of a sad and lonely dog. The story is told through a unique collaboration of art forms and artists, combining puppet artistry, circus art, mime, and dogs trained in theater performance. Puppets give voice to the story, while professional circus artists and their dogs enact the plot of caring, rescue, and love.
From the noise of an urban landscape to the musical cocoons created by high-tech devices, sound may be humanity's most lively and versatile interface with the world. Takes viewers on a sonic odyssey that assesses the frequently overlooked impact of what humans hear. Takes a CGI tour through the human ear and its vibration-decoding systems, defining the concept of sound. Also demonstrates the importance of sound in human spiritual and religious lives, while musical research at Edinburgh University highlights the link between sound patterns and human movement. Several experts, from physicists to sound engineers to audio artists, contribute to this exploration of humanity's sonic world.
The heart is the most symbolic organ of the human body. Across history, it has been seen as the source of emotions and the center of human existence. However, by the seventeenth century, scientific understanding overturned historical ideas, and the heart was recognized merely as a mechanical pump. More recently, Professor David Paterson from the University of Oxford has been doing extensive research that challenges this view. He has discovered that the heart has millions of specialized neurons just like those that are in the brain. Neurons are the cells that give humans the ability to think. So what does their presence in the heart mean?
