Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the crew continues to observe a variety of bacteria. They discover that bacteria is the food of choice for large single celled protists in the pond. Their observations lead them to make conclusions about the food chain found in the pond. Part 6 of the Microscopic Monsters Series.

The Hawaiian bobtail squid and its resident bacterium, Vibrio fischeri, have a powerful and still somewhat mysterious symbiotic relationship. The luminescent bacteria populate a small pouch on the squid’s underside called the light organ, and provide a sort of “Klingon cloaking device.” They produce light at night to offset the squid’s shadow and hide it from predators when it approaches the ocean’s surface to feed. At the University of Wisconsin-Madison, microbiologist Margaret McFall-Ngai studies this unusual relationship. An understanding of these creatures’ rhythms could lead to new ways to treat disease. She is also studying how the squid and bacteria communicate, so they don’t harm each other.
Leaf cutter ants could be called the overachievers of the insect world. They are farmers, medicine makers, and green energy producers. With support from the National Science Foundation, bacteriologist Cameron Currie studies the complex evolutionary relationships between the ants, the fungi they cultivate and eat, and the bacteria that influence this symbiosis. At the University of Wisconsin-Madison, Currie works with the Great Lakes Bioenergy Research Center on campus to explore how the ants manage to degrade cellulose. Her goal is to discover new ways humans might break down biomass into biofuels. The bacteria component of the ant colony could also help scientists develop more effective antibiotics for human health and agriculture.
Monitoring water quality is vital to make sure dangerous bacteria doesn't creep into drinking water or overcome sewage treatment plants. With support from the National Science Foundation, engineers at the Monterey Bay Aquarium Research Institute have developed the Environment Sample Processor (ESP), a "DNA lab in a can." The size of a trash can, it can be placed in the open ocean or at water treatment facilities to identify potentially harmful bacteria, algae, larvae, and other microscopic organisms in the surrounding waters. It can monitor and send results back to the lab in real time to monitor water quality. Now, the engineers are modifying the ESP so it can go mobile, working from an autonomous underwater vehicle (AUV).
Microorganisms affect everyone. Some are helpful, while others are harmful. Explores pathogenic microorganisms that can cause diseases like sore throats, influenza, tuberculosis, and HIV; decomposer microorganisms that decay rotting plant and animal matter, returning important nutrients back into the soil; and microorganisms that are also being used in the fuel industry to develop new nonpetroleum based products. Overviews food spoilage microorganisms such as mold that can ruin stored food. Explains other bacteria and yeasts are vital to the production of food and drinks like yogurt and bread, along with beer and wine. Examines where they come from and some examples of positive uses relating to many foods we eat.
Anna was born with a sweet tooth, and as a young woman, she created a successful business using it. Her delicious jams and jellies gave pleasure to many, but did they also cause harm? Explores the way the human body processes food and how its long-term growth and development are shaped by eating habits. Illustrating cellular aging and its relationship to AGEs, or advanced glycation end products, a connection is drawn between the bacteria an infant must consume to build a healthy immune system and the bacteria that consume the body at death. As Anna's life draws to a close, viewers will understand that "dust to dust" is a cycle in which humans take an active part--every time they sit down to a meal.
What is the domain Archaea? This episode compares and contrasts characteristics of Archaea with bacteria. Part of "The Amoeba Sisters" series.
Natural selection is a mechanism of evolution. In this episode, Pinky and Petunia discuss the relationship of natural selection and antibiotic resistance in bacteria. Part of "The Amoeba Sisters" series.
Millions of years ago, a group of bacteria, the cyanobacteria, developed a new way to harness energy from the sun. This new development had important consequences for the evolution of both the atmosphere and the diversity of life on Earth.
Many microorganisms thrive in the polluted water that is abundant with their food: bacteria and other protists. One of nine segments in a series, with all nine available on a DVD.
What great discovery is yet to be made from coral reef habitats? Some researchers believe they may hold the key to new developments in medicine. Part of the "Coral Comeback" series.
Host Trace Dominguez discusses the science behind getting a fever when sick. Fevers are integral to effective immune responses and ensure the immune system takes appropriate action against the offending virus or bacteria. Part of the "Uno Dos of Trace" series.
Part of the "Branches on the Tree of Life" series. Describes the discovery of viruses and their structure, how viruses are studied, how they infect their hosts, and how they replicate. Provides details on the T-4 bacteriophage and retroviruses, such as HIV.
This video explores the fascinating world of microscopic life. It begins by discussing viruses and explaining how they cause disease. Students also learn the importance of bacterial cells and explore the life of protists. Additional concepts and terminology include microscope, vaccine, moneran, decomposition, amoeba, phytoplankton, yeast, algae, paramecium, and protozoa.
Are there living organisms in yogurt? What happens when milk and yogurt are left out of the fridge for a night? The scientists explore this and show how to fix a dented Ping-Pong ball. Part of the House of Science Series.
A good story is not necessarily a true story. In this episode, host Joe Hanson takes a look at a few of the most famous incorrect factoids in science. He also gives some tips on how to not be fooled by scientific urban legends. Part of the "It's Okay to Be Smart" series.
The bobtail squid is no bigger than a walnut and is a tasty mouthful for predators in the coastal waters of Hawaii. However, the species continues to thrive in these waters in part because of its symbiotic relationship with a bioluminescent bacteria, which renders the squid virtually invisible to predators. Part of the "I Contain Multitudes" series.
There’s fool's gold in the ocean, and this mineral helps support life in the ocean. Scientists have been studying how bacteria and small plants in the ocean get the iron they need for energy and growth. Well, new research points to mineral sources on the seafloor. Part of the "News of the Day" series.
Viruses are tiny agents that can infect a variety of living organisms, including bacteria, plants, and animals. The Dengue virus is a mosquito-borne viral disease occurring in tropical and subtropical areas. Scientists at the University of California, Berkley have identified a key culprit responsible for the severe symptoms related to Dengue fever.
A new transmitter helps protect wireless data from hackers. Other features in this episode include bacteria using DNA to speed their evolution and a new next-generation water harvester that delivers fresh water from air. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
