Issue 1 - THE HUMAN HOST
Remarkable photography offers a rare look at some life forms that share our world very closely - organisms that may live in or on our bodies, hitch an occasional ride, or take their nourishment from us. Most are harmless, and live without our ever being aware of them. Many are beneficial while others cause discomfort or disease. Students will remember this ecology lesson as they learn what can happen if their body's natural balance is disturbed and how disease can spread from one host to another. - 13 Minutes

Issue 2 - CHANGING NATURE'S BLUEPRINT
In this thought provoking program, we see how scientists are using nature's blueprint... DNA... to genetically engineer pharmaceuticals to cure hereditary and acquired diseases. With the help of sheep, scientists found a way to manufacture factor 9, which gives blood its clotting ability, and hope for a cure for hemophilia. - 13 Minutes

Issue 3 - FUNGI - NEITHER PLANT NOR ANIMAL
This issue surveys the kingdom of the fungi, the intriguing and varied life forms that are neither plant nor animal. Fungi can be both harmful and beneficial. We show why, as well as some of the new ways we are using them to grow healthier crops, fight insect pests, and treat diseases. - 15 Minutes

Issue 4 - UNDERSTANDING FROGS AND TOADS
Fossils prove the existence of these amazingly adaptable amphibians one hundred million years ago, and they can be found today on nearly every land mass. Featured, along with the typical frog/toad life cycle and defenses, are some of the interesting variations many species have developed in response to their particular environments, as well as why these animals are biologically important, and of special interest to scientists. - 22 Minutes
