This interactive video explores how two scientists tracked the 2013 Ebola outbreak in West Africa. 

This interactive video explores how scientists identify which bat populations are infected with Nipah virus and could transmit the virus to humans.

This interactive module explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

This model shows the structure of dengue virus, which causes dengue fever.

This model shows the structure of Nodamura virus, a type of nodavirus.

This model shows the structure of rhinovirus, which causes the common cold.

This interactive module shows how DNA sequences can be used to infer evolutionary relationships among organisms and represent them as phylogenetic trees.

This tutorial introduces students to vector-borne disease with a focus on dengue fever, which is transmitted by mosquitoes. Students also learn about strategies designed to stop the spread of disease by interfering with the mosquito life cycle.

This tutorial describes how DNA microarrays called Virochips are designed to detect known viruses and discover new ones.

This tutorial explores the effects of West Nile virus infection on different organisms and describes how the virus has spread throughout the United States since 1999.

This interactive module allows students to compare the morphological characteristics of seashells and construct an evolutionary tree.
