Parakeet talks about the importance of proper animal treatment. The first guest, the dog, accuses cat of wanting to steal his master. The cat says he's just looking for a home and since the dog's master has adopted him and doesn't abuse him like his old masters, he doesn't think he's doing anything wrong. The fleas show a documentary on animal abuse and how humans often abuse and abandon their pets. The celebrity guest, Babe the brave little pig, talks about an experience on a farm which can be useful when compared with the story of the dog and cat. Babe explains the farmer shares his love with all 20 of his animals.

When the water along Rhode Island’s Narragansett Bay is thick and green, it may be a bad day for a swim, but it’s an excellent day for University of Rhode Island marine ecologist Carol Thornber. Thornber and her team are conducting a long-term study of the impacts of climate change on macroalgae, or seaweed, and algal blooms. She is investigating how the blooms affect fish stocks and oyster beds as well as how nutrients in the water from sewage treatment and agricultural runoff can feed the blooms and make them larger. Part of the "Science Nation" series.
To what degree are we genetically programmed with certain traits and abilities? Looks at recent technologies and scientific discoveries and considers the classic "nature versus nurture" discussion. Segments cover identical twins, the science of biotechnology, and the genetic inheritance of working dogs. Investigates the similarities in personality shared by identical twins. Explains how recent breakthroughs in genetics research and DNA have created new ways to solve crimes, breed (clone) animals, and extend human life. Discusses cross-species cloning, human cloning, and gene therapy. Shows how assistance and search-and-rescue dogs can be taught to overcome their inborn instincts and fear.
Water is used by everyone, and in the process, a lot of it goes to waste. Whether it goes down drains, sewers, or toilets, much of it ends up at a wastewater treatment plant where it undergoes rigorous cleaning before it flows back to the environment. The process takes time, money and a lot of energy. What if that wastewater could be turned into energy? It almost sounds too good to be true, but environmental engineer Bruce Logan is working on ways to make it happen. With support from the National Science Foundation, Logan and his team at Penn State University are taking the idea a step further. They are developing microbial fuel cells to channel the bacteria's hard work into energy.
Gene therapy is a method for treating inherited diseases by delivering corrective versions of genes to patients. Dr. Jean Bennett and Dr. Albert Maguire focused their careers on developing a successful gene therapy for an inherited form of childhood blindness called Leber congenital amaurosis (LCA). This documentary tells the story of how the LCA gene therapy was developed. Students will learn how autosomal recessive conditions are inherited, how scientists can use modified viruses to deliver human genes to cells, what makes the eye an ideal tissue for gene therapy, and how model organisms are used to test treatments before they are tested in patients.
