New ReviewSlow the spread of disease by slowing disease carriers in their tracks. Learners explore just how they might accomplish this as they experiment with the life cycle of a mosquito under different conditions. Scholars design and conduct...

New ReviewMore than 144 sub-types of influenza A exist today. How is that possible? Scholars view an animation of a cell being attacked by two different strains of the flu. Then the strains mix, creating an entirely new third strain. The idea of...

New ReviewAn outbreak of illness hits a refugee camp and the local population worries about the spread of the deadly disease. Scholars virtually travel to the area to determine what causes the disease and how it is spread. Next, they must put...

New ReviewThis lesson has gone viral ... literally! An animation video describes how a single virus cell gives rise to a multitude of progeny viruses. Learners explore how a virus infects many cells in a short amount of time.

New ReviewCalling all science sleuths! A patient appears to have a disease eradicated years ago—how do you treat it? Scholars must research the illness, the possible causes, and find a cure before the disease spreads and wipes out the entire city....

New ReviewA dozen years after a great plague wipes out the majority of Earth's civilization, a group of scientists joins together to fight infectious diseases. Scholars join the training mission and learn about viruses, bacteria, pathogens and...

Some scientists now consider the gut microbiome a distinct organ in the human body. Curious science scholars learn about this ecosystem thriving inside them and its important functions with a video from Our Hungry Planet. The 11th lesson...

From quantum foam to the universe itself, plus everything in between, what is the scale of the world around us? Inquisitive physicists grapple with the proportions of all things great and small using a fascinating interactive. Scholars...

Doctors offer limited treatment options and no vaccine for Dengue Virus, which often requires intensive care. Scientists understand how the virus gets into cells and replicates, knowledge which they hope will lead to a cure or treatment....

The number of diagnosed cases of Dengue Fever increased exponentially over the course of three decades. A brief video explains how the potentially deadly virus spreads. For added impact, scholars view the number of cases in each country...

Dengue Virus leads to the deaths of around 25,000 people, mostly children, every year. Scientists understand how the virus gets into cells and replicates, but they still struggle to prevent it. Curious scholars view an animation of the...

Viruses might be deadly, but they appear beautiful when analyzed geometrically. View the shapes, colors, and structures of a few viruses. The repeating structures and genes help to identify them along with genomic information.

Virochips detect and identify viruses at a higher rate than other tests. Show young scientists how Virochips work to identify existing viruses. They analyze results demonstrating mutations or the evolution of viruses and view videos...

The dengue virus looks like a ball with multiple layers. View an animation of each layer while hearing a description of its properties, from the outer symmetrical units to the lipid envelope, the capsid, and finally the RNA genome.

Thanks to a new understanding of DNA sequencing, doctors now study viruses outside human bodies. Observe an animation of the process using a Virochip to better understand viruses and how they connect to our DNA. By comparing results to...

When did things start going viral? Travel back through eons of history and learn about the origins of viruses. Part of a larger series, the lesson discusses what scientists already know and how they study viruses. The video also details...

Eight percent of DNA comes from retroviruses. Learn what sets retroviruses apart from other types of viruses with an presentation that focuses on the differences between viruses with a DNA genome, an RNA genome, and retroviruses. 

How does your body know when to present an immune response? Viewers observe how antigen presentation triggers the response and how this treatment helps attack viruses before they spread. The video also discusses the challenges of...

Almost half of the global population infected with HIV cannot afford treatment. To better understand this devastating disease, young scientists observe the life cycle of HIV.  Through animation, they see the cell infection, replication,...

Protease inhibitors currently treat HIV and hepatitis C, but in the future, might also be used to treat some cancers. Viewers learn how HIV spreads in the body and then observe what happens after the introduction of a protease inhibitor. 

Unending war, battles on every front, increasing offenses and defenses as the sides adjust to each other ... these phrases describe your body fighting viruses. From a common cold to deadly Ebola, cells adjust and defend life themselves....

Scholars learn the differences between RNA and DNA through discussion, virtual labs, worksheets, and video quizzes. They build their knowledge of molecular biology with support from video clips and handouts.

How much do you know about microbes and our understanding of pathogens? A quick 15-question quiz tests a broad range of information related to microbes. The interactive presents a score at the end, providing a great opportunity to review...

Molecular engineers play with RNA to develop new therapies that could save lives. Young scientists fold RNA into specific shapes using the pairing rules. They apply knowledge about the relative strength of bonds and shape-shifting RNA...
