In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO₂ starting in 1958.

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 introduces the anatomy of the immune system and walks through the timeline of a typical immune response.

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 explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

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 examines Earth’s past and present climate, highlighting the effects of two important factors: solar radiation and the composition of the atmosphere.

This interactive module explores how the changes in oxygen levels throughout Earth’s history have impacted the planet’s environment and types of life.

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.
