Natural selection is a process which affects every species on Earth, including humans. Illustrates how it continues to affect humans all in fundamental ways that will determine the future survival as the species. Includes a brief explanation of natural selection, examples of how it is operating all around humans, how it has affected human evolution, and how it is still affecting daily lives. Concludes with the reciprocal view of how modern human society is affecting the processes in the environment, and the consequences for the future of life on Earth.

Northwestern University Mechanical Engineering professor Todd Murphey and his team are engineering robots to mimic humans. With support from the National Science Foundation, the team is using algorithms to enhance a robot’s ability to adapt to human behaviors. Part of the "Science Nation" series.
Though tool use is not unique to humans, their sophistication and degree of reliance upon them is unique, and sets humans apart from other species. So when did human tool-making begin, and why? And what does the use of tools reveal about the evolution of human ancestors? Paleoanthropologist Tim White reveals the answers in this short video.
Students are encouraged not only to respect other people, but also their surroundings. Widens viewers' perspectives from their own homes to schools to towns to the planet. Rhymes, stories, and real-life experience help emphasize how the earth is interconnected.
An expert on exercise physiology discusses the importance of different elements of fitness, and teenagers share personal stories about how exercise helped them achieve and maintain a healthy weight. Exercise also helps build strength, develop endurance, improve agility, boost self-confidence, and connect socially. John Ratey, a professor of psychiatry, describes the growing evidence that aerobic exercise remodels our brains, making us sharper mentally, and providing protection against mood disorders. Teens describe how exercise helped them deal with depression, anxiety, and stress.
What happens in your brain when you get lost or forget something? Johns Hopkins University Neuroscientist Amy Shelton believes she can find the answer. With funding from the National Science Foundation, she’s testing human spatial recognition. Study subjects learn and recall their way around a virtual maze while an MRI scans their brains. By analyzing MRI images of blood flow in the human, Shelton can get a picture of how the brain learns and recalls the spatial world outside the body. By understanding those processes, she believes she can develop techniques that will help improve human memory.
Human ancestors in Africa likely had dark skin, which is produced by an abundance of the pigment eumelanin in skin cells. In the high ultraviolet (UV) environment of sub-Saharan Africa, darker skin offers protection from the damaging effects of UV radiation. Dr. Jablonski explains that the variation in skin color that evolved since human ancestors migrated out of Africa can be explained by the tradeoff between protection from UV and the need for some UV absorption for the production of vitamin D.

Human babies drink milk; it's the food especially provided for them by their mothers. Various cultures have also added the milk of other mammals to their diet, and adults think nothing of downing a glass of cows' milk. But worldwide, only a third of adults can actually digest lactose, the sugar in milk. Human geneticist Spencer Wells tracks down the genetic changes associated with the ability to digest lactose as adults. Combining genetics, chemistry, and anthropology, this story provides a compelling example of the co-evolution of human genes and human culture.
New scientific evidence suggests that some wolves evolved into dogs by domesticating themselves, and not by humans taming them. Features evidence that dogs have traveled and been buried with humans since prehistory, adapting to every climate and evolving into many subspecies or types of the same dog species. Human cultures might not have evolved as they did without the help of the dog, our most cherished and probably first domestic animal companion.

Drug addiction is a disease of the brain, and teens are at the highest risk for acquiring this disease. Stephen Dewey and other leading scientists detail how drugs like heroin, nicotine, cocaine, and marijuana change the brain by altering the way it registers pleasure. Young recovering addicts describe how addiction involves intense craving for a drug and loss of control over its use.
Experts Eli Green, Jaymie Campbell, and Alessia Palanti define pertinent terms like cisgender, transgender, gender identity, gender expression, and pronouns. Viewers learn about gender norms and stereotypes that affect all people, no matter how they identify on the gender spectrum. Teens describe their personal experiences with gender and explain the critical importance of allies in their lives.
A taxonomist explains the current classification system for all living things. Beginning with Aristotle's two kingdom division, today there are five kingdoms, with talk of changing to six. Uses the product groupings in a grocery store to clarify the concept. Looks at the differences of each kingdom: Monera, Protista, Fungi, Plantae, and Animalia. Stresses that the more we learn, the more likely this system will change yet again.

In many ways our brains may be like those of animals, but in our capacity to think, to remember, and to create we are much different. Looks at some of the reasons for these differences, exploring the neural structure of the human brain, our physiological brain capacity, and the use of memory and symbols.
