Researchers explore how different types of biomass can be used to produce fuel. One researcher is building reactors to grow algae used to create biofuel. A different study examines how leafcutter ants break down biomass in order to convert cellulose in plants to a fermentable sugar used to make ethanol. Finally, an engineer uses chemistry and heat to turn sawmill waste into bio-oil and gasoline.

Visible light, which can be seen with human eyes, comprises a small sliver of the electromagnetic spectrum. The rest of the spectrum, from short wavelength gamma rays to long-wavelength radio waves, requires special instruments to detect. ALMA uses an array of radio telescopes to detect and study radio waves from space. ALMA is an advanced tool for studying very old stars and galaxies. These objects now are seen at great cosmic distances, with most of their light stretched out to millimeter and sub-millimeter wavelengths by the expansion of the universe. ALMA provides the unprecedented ability to study the processes of star and planet formation.
Host award-winning geoscientist, Richard Alley provides an eye-opening look at some of the world's most important case studies in smart energy. Alley travels to Spain and Morocco where large-scale solar farms and individual photovoltaic panels atop tents in the Sahara are beginning to bring the vast potential of the sun down to Earth. In Brazil, abundant natural resources are transformed into efficient, sustainable biofuel, making Brazil the only nation whose cars could keep running if all gasoline were to vanish. In Denmark, and West Texas, citizens have taken sustainability into their own hands by becoming stakeholders in wind turbines. And in China, he explores multiple sustainable energy technologies, including exclusive footage from GreenGen, the world's most advanced low-carbon emissions power generation plant.

Investigates the digestive consequences when a family sits down to lunch. As the first morsel is put into the mouth, the camera watches from inside as the molars clamp down and the process of breakdown and transformation occurs. Follows the food through the entire alimentary tract, showing how it is dissolved in acid, how the liver and gallbladder work, and how digestion and absorption work.
In this program, students learn about the digestive process. The human digestive system consists of the gastrointestinal tract plus the tongue, salivary glands, pancreas, liver, and gallbladder. Digestion involves the breakdown of food into smaller and smaller components. These small components are absorbed and assimilated into the body. Part of the "Human Nutrition" series.
