Individuals need to understand the meaning of virus, spyware, phishing, the difference between a hacker and a cracker. Computer users also need to know it is not enough to have a strong email password or an antivirus to avoid falling victim to online criminals. Informed users of technology have the guarantee of security to surf the internet and not become victims of fraud or cybercrimes.

Discussions related to sex education and prevention strategies may not be appropriate for this age group, so this simply provides a baseline of knowledge about HIV and AIDS. Covers the definition of HIV and AIDS, transmission, progression, treatment and the importance of treating HIV-positive people with respect and compassion. Presents information through a lens that emphasizes healthy decision-making.
Explore the techniques plant physiologists use to study viruses. Viewers discover how breeders produce tulips with the desired durability, disease resistance, and beauty. Part of "The Botany of Desire" series.
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.
Part of the "Visualizing Cell Processes" series. Includes the following modules: "The Protein Nature of Life," "Protein Structure," "Transcription," "Translation and Protein Synthesis," "Gene Regulation in Prokaryotes," "Classes of Eukaryote DNA," "Exons and Introns," "Mutations," and "Renegade DNA: The Viruses."
We often hear about insects and other animals passing on diseases to humans, so-called zoonotic diseases, such as rabies, cholera, and West Nile virus. Now, for the first time, researchers are examining a disease that humans are spreading to an animal, specifically Elkhorn coral off the Florida Keys. With support from the National Science Foundation, Rollins College biologist Kathryn Sutherland is tracing this emerging infectious disease phenomenon, known as “reverse zoonosis.” Elkhorn coral was once the most common coral in the Caribbean, but it's now a threatened species due to population losses from White pox disease. Sutherland believes undertreated sewage, possibly from leaking septic tanks or illegal cruise ship discharge, could be the source of this disease.
Throughout the last few decades, diseases that jump from animals to humans have been on the rise. What’s behind their increase, and what can the world do to combat these dangerous foes? Join scientists as they investigate the rise of spillover viruses and learn how to anticipate and prevent epidemics around the world. Please note this title shows images of persons suffering from the diseases in this title.
Biological vectors carry and transmit diseases that affect plants, animals, and humans. This program focuses on diseases transmitted by mosquitoes and ticks. Students will learn how scientists use the information they gather to help control and prevent the transmission of vector-borne diseases around the world. Part of the "Real World Science" series.
Mosquitoes are annoying pests. They can interrupt a backyard picnic, and their bites cause red, itchy bumps. These pests can also carry viruses that make humans sick. In this episode, learn how and why the invasive Asian tiger mosquito is even more problematic than other varieties. Part of the "Seasonal Science" series.
The body is like a self-supporting hospital, able to deal with its own with wounds, bacterial invasions, fractures, and obstructions to its various passages. Follows the sequence of events over seconds and weeks when skin or bone is damaged, and shows the defensive reactions of blood clotting, fever, and mending of bone fractures.
In this episode, researchers are exploring ways to make carbon nanotubes less expensive. The process would use carbon dioxide sucked out of the air. Researchers are also working to identify bacteria and viruses found in ocean spray. Also in this episode, scientists are attempting to design a battery that would charge electronic devices in seconds. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Presents a brief history of what new information caused the classification of living things to evolve from the original two kingdom classification of animals and plants by Linnaeus in the 18th century to the present-day six kingdoms: Animal, Plant, Fungi, Protista, Eubacteria, and Archaebacteria. Discusses three of the six kingdoms: Protista, Eubacteria, and Archaebacteria. Also, presents the hierarchical classification from kingdom to species. Because viruses do not have the capability of an independent cellular life, they are included in neither the kingdom nor domain classifications.
Sea spray aerosols occur naturally in the salty ocean air, and there’s much more in each of those tiny bursting bubbles than salt. They’re bursting with ocean life, from bacteria to phytoplankton--even viruses. Because sea spray aerosols seed clouds, they affect the climate. With support from the National Science Foundation (NSF), atmospheric chemist Kimberly Prather of the University of California, San Diego, and chemist Vicki Grassian of the University of Iowa are leading a team of scientists around the country who are working to better understand what role sea spray aerosols play in weather and climate change climate models. Part of the National Science Foundation Series “Science Nation.”
