Harvard economist Alvin Roth is a matchmaker but he’s not finding love – he’s finding kidneys. With support from the National Science Foundation, he and his team have developed a suite of computer programs that match living kidney donors with recipients. Why is an economist organizing kidney transplants? It turns out that an understanding of game theory and market dynamics is key to optimizing pairings. It's all about streamlining complicated matches using the science of the marketplace. Their matching software is the engine that has helped transplant centers in 30 states so far. Part of the National Science Foundation Series “Science Nation.”

Goodwill Industries takes donations of items that people don’t want anymore. Clothing is a majority of the items that Goodwill receives. In this episode, the Curiosity Quest crew learns about the environmental efforts of Goodwill to find a home for donated clothing. Part of the Curiosity Quest Series.
Organic acids, found in common foods, appear as citric acid (lemons), acetic acid (vinegar), and malic acid (apples). Also shows esterification and the formation of an ester.
They're neither plants nor animals, yet they are some of the most important life-forms on Earth. This video segment explores the world of single-celled organisms: what they eat, how they move, what they have in common, and what distinguishes them from one another.
Organics are carbon-based molecules and key ingredients to life. Scientists want to know if organics can be found on Mars. However, finding organics is difficult because they easily break down when exposed to harsh things like extreme radiation and chemical oxidants. These broken down particles give the Martian surface its rusty color. Part of the “Mars in a Minute” series.
Learn how organic farmers diversify their crops and control pests with natural enemies in order to farm without chemicals. Viewers also explore the economics and impacts of traditional and organic farming. Part of "The Botany of Desire" series.
What happens to waste after it is discarded? Treating discarded waste consumes many resources and hours of man power. A walk through the facilities of CEAMSE reveals what happens to discarded items and the residue they leave behind.
How does organic farming differ from other methods? A team explores soil conditions, water availability, climate, and different techniques.
As scientists discovered more and more chemical elements, they began developing systems to organize the elements by their chemical properties, leading to the modern periodic table. Through its organization, the periodic table makes clear the underlying chemical and physical trends among the elements. The periodic table is being continually updated even today as scientists strive to create new elements in laboratories. Part of the series Chemistry: Challenges And Solutions.
Biodiversity, or biological diversity, refers to the variety of plants, animals, and microorganisms that exist. The biodiversity of an environment is important because it helps keep the environment in a natural balance. An ecosystem which is species-rich is more resilient and adaptable to external stress than one in which the range of species is limited. Part of the "Biology" series.
The most common bacterial shapes are rods, cocci (round), spirals and filaments. Groups of these cells can be differently arranged in space. Four 3D-printable models illustrate these shapes and arrangements.

Part of the "Green Careers" series. Provides an inside look at an organic farm and an organic retail store. Discusses the daily challenges and rewards of working in this field. Organic farming includes a wide range of jobs in production, marketing, and distribution. Jobs profiled include the following: farm manager, retail sales manager, and organic produce buyer.
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.
Protists are a diverse collection of organisms. Watch this animated video to find out how these single-celled organisms function.
Part of the "Gunther's ER" series. As Dr. Gunther von Hagens makes clear, a shortage of blood can mean that insufficient oxygen is reaching the major organs, usually resulting in shock and organ failure. Opens with a graphic bleeding demonstration, re-creating injury to blood vessels in the hand of a cadaver. Also examines the consequences of blood loss in the body's vital organs by creating knife wounds in the torso of a frozen body, then sawing it into slices to reveal the path of the blades and the shocking extent of the damage. Also explores a lesser well-known cause of blood loss-fractured bones-which von Hagens illustrates in an experiment in which a femur dissected from a fresh cadaver is made to bleed as it would in life. NOTE: Viewer discretion is advised. Contains clinically explicit language and nudity.
For a few weeks each year, vernal pools explode with a diversity of microscopic and small animal life. Visually examines the plethora of living organisms often found in these vibrant, temporary pools.
Part of the "Life in Aquatic Environments" series. Places many of the organisms into an ecological perspective of hydras, planarians, annelids, aquatic insects, rotifers, protists, and all other organisms that provide food for fish and other vertebrates. Observes adaptations for planktonic life in daphnia and other cladocerans, copepods, rotifers, and planktonic algae. Explores bacterial decomposition, recycling of materials, adaptations for bottom life, and ecological relationships in the bottom community. Takes an underwater look at the highly specialized organisms that live in rapids, under rock communities, and in slower waters. Investigates adaptations for life in temporary wetland environments.
All living organisms on Earth contain cells which are the basic structural unit for all organisms. Cells are small compartments that hold the biological equipment necessary to keep an organism alive. They also have specific parts to make the cell work.
Touch, taste, smell, hearing, and sight: the human body's five major senses. They are senses that have evolved independently over millions of years but are brought together by our marvelous central nervous system into the most refined way of interacting with the environment of any species on the planet. Join Dr. Mark Reisman as he provides you with a look at the anatomy and physiology of each of these sensory systems and shows how the brain uses them to produce what we call being human.
Explores the microscopic organisms known as the ciliates. They are named for the tiny hairs that cover their bodies. Discusses different species, their habitats, and how they survive. One of nine segments in a series, with all nine available on a DVD.
