  • Small, furry animal with a pointed head and nose. Caption: meerkats emerge just after sunrise.

    Explores the open savannahs of Africa, particularly the mammals that inhabit them and the trees that border the grasslands. Shows how the different animals interact with each other and the non-living elements of their habitat to maintain a healthy balance. Also investigates the threat from an increasing human population for homes, food, other resources, and the resultant threat to the survival of many animal groups. Looks at international breeding programs around the world, which were established to protect these animals and enable them to reproduce in captivity, so their gene pool is preserved.

  • Black hummingbird with a white breast in flight. The wings are blurry because they are moving so fast. Caption: And it's no wonder they eat so much.

    Hummingbirds live only in the Americas, and their diversity numbers 350 species. They are part-time carnivores that must catch animals that compromise ¼ of their diet. Demonstrates how they can hover, fly backward, and move their wings in figure eights at 200 wind-beats per second in slow and stop motion images. Also reveals that every night their bodies go in torpor (mini-hibernation) so they don't starve while they can't consume nectar. Also sees how they co-evolve with flowers through pollinating mutualisms, and acquired their aerial skills by evolving from ancestors of swifts, their nearest relatives.

  • Microscopic view of small, tube-like structures. Caption: Two kinds of cells make up the living world:

    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.

  • A self healing reverse filter. On screen text, 1 centimeter. 1 time real time, 7 to 3 ratio, D I water to glycerol, 0.0083 M S D S. Caption: and it self heals after the object passes.

    In this episode, researchers discuss the novel applications for a self-healing reverse filter. For example, researchers are studying its application in unsanitary environments. Scientists also ask the question: Is laziness a fruitful strategy for the survival for some species? Researchers are studying the link between metabolic rate and extinction. In the final segment, weather forecasts are predicting that El Niño and La Niña are likely to intensify wildfires and increase drought risk. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
