All living organisms share several key characteristics or functions. When combined, these characteristics serve to define life. In this episode, Petunia and Pinky discuss several of the characteristics of life. Part of "The Amoeba Sisters" series. Please note: This title contains discussions on sexual reproduction.

What happens when a whale dies? This short piece explores the concept of decay, and the role decay plays in giving life to other organisms.
The diversity of rotifers is stunning, and many different species are overviewed. Planktonic rotifers have special adaptations for open water life. Nematodes (roundworms) include a number of important human parasites, seldom seen but easily found. Tree moss, leaf litter, and compost piles swarm with nematodes.
Shows the structure, behavior, and life cycles of planarians and their free-living relatives (class Turbellaria). Illustrates the bizarre life cycles of flukes (class Trematoda) and tapeworms (class Cestoda) with detailed animations and revealing images of these parasites in action.
Part of the "Inside the Living Cell" series. Provides an overview of the different kinds of cells, emphasizing the fact that all cells have a common organizational structure and carry out similar biochemical processes. Presents the discovery of cells, cell structures, organelle function, cell varieties, and the chemistry of life.
Part of the animated "Johan, the Young Scientist" series. Housebound during a rainy day, Johan goes to ScienScape where it also rains. Johan, Ani, and Moki set out to find where the rainwater ends up. This leads them from gutters to drains to rivers. They soon learn that all living beings need water to survive.
Ten 10-minute programs explore temperate and tropical habitats and their abundant diversity of life. Tape one: compares temperate and tropical forests, their habitats, the effects of rain on them, and shows how size can generate great diversity. Tape two: uses butterflies to represent species diversity, compares how people relate to temperate and tropical environments, explores humans' impact on diversity, and investigates issues of threatened and endangered species.
From fossil evidence, it appears that life may have existed on Earth as early as 3.5 billion years ago. This suggests that life must have evolved sometime during Earth's tumultuous first billion years. How did life evolve? What did early forms of life look like? Topics covered include protocells, endosymbiosis, prokaryotes, eukaryotes, evolution, heredity, variation, natural selection, genetic drift, and gene flow. Part of the "Biology" series.
Updates the five kingdoms classification scheme with the latest understanding of life's organization based on DNA, fossil, and biochemical evidence, reorganizing all life into three great branches: Archaea, Bacteria, and Eucarya. Shows concise animations and superb microscope footage of primitive cells.
Explains why the body needs regular supplies of air and how these get to the body. The camera follows the process of breathing through the ultra-thin membrane of the lung into the blood, showing how the varying demand for oxygen is met by the exchange of information between the brain and the chest muscles and how the body rids itself of carbon dioxide.
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.
Anna has built a successful business from the ground up, and upon retirement, she leaves the company to her employees, not to her son. What does that decision tell us about Anna's psychology and about the development of the human brain over a lifetime? Explores the emotional and neurological elements of learning, explaining how the brain processes and stores experiences and prepares for future decision-making. Employing real-to-life dramatizations, Anna's journey from innocent teenager to philosophical retiree--and the changes that take place in her cortex, hippocampus, and neural synapses as she faces and overcomes challenges--are all depicted. In addition, several influential brain experiments from the past decade are described.
Anna was born with a sweet tooth, and as a young woman, she created a successful business using it. Her delicious jams and jellies gave pleasure to many, but did they also cause harm? Explores the way the human body processes food and how its long-term growth and development are shaped by eating habits. Illustrating cellular aging and its relationship to AGEs, or advanced glycation end products, a connection is drawn between the bacteria an infant must consume to build a healthy immune system and the bacteria that consume the body at death. As Anna's life draws to a close, viewers will understand that "dust to dust" is a cycle in which humans take an active part--every time they sit down to a meal.
Glaciers are one of the main driving forces affecting Earth's climate and landscape. These massive sheets of ice are constantly moving and changing, and warming temperatures are causing most glaciers to recede. Located in some of the most inhospitable areas of the planet, scientists are venturing to glaciers to study them and looking for clues from past and present changes in climate. Part of the "Glacier Series."
With support from the National Science Foundation, chemist Kent Kirshenbaum and his team at New York University are engineering molecules to mimic the shapes, structures, and functions of natural proteins. The ultimate goal of this biomimetic chemistry research is to develop a reliable way to build synthetic proteins that can be put to work at the industrial scale. Part of the "Science Nation" series.
The children learn about the transformation of water. They watch as the droplets change into rain, vapor, and even a tear on Olli's cheek. Part of the "My Little Planet" series.
Demonstrates techniques for using a student microscope to achieve spectacular images. Emphasizes correct lighting procedures and the techniques required for viewing living cells.
Host Emily Graslie travels to an unstudied rain forest. While there, she helps a team of scientists document the reptiles and amphibians they find during night excursions. Part of "The Brain Scoop" series.
In this episode, host Emily Graslie interviews Dr. Robert F. Inger. His career in science spans over seventy-four years, and he published his first scientific paper in 1942. He is a renowned herpetologist. The greatest lesson he has learned is to never stop asking questions and seeking answers. Part of "The Brain Scoop" series.
Characteristics of the Mediterranean climate include great weather, abundant harvests, and some of the world’s most cosmopolitan cities. These climate zones also house diverse ecosystems, which are dependent of the geology of the regions. Part of the "Mediterranean-Climate Ecosystems" series.
