  • Why Two Heads?

    Why Two Heads?

    Phenomenal Images

    Students explore images of planarians regenerating body parts as phenomena to explore cell division and differentiation.

  • Age Structure of Ebola Outbreaks

    Age Structure of Ebola Outbreaks

    Data Points

    Scientists analyzed demographics, including sex and age, of the spread of the Ebola Virus Disease during seven outbreaks in the Democratic Republic of Congo.

  • Monkey Social Status and Immune Response

    Monkey Social Status and Immune Response

    Data Points

    Scientists studied how the dominance ranking of female rhesus macaques living in social groups affected the expression of genes linked to immune response.

  • Maternal Microbiota Impacts Offspring Immune System

    Maternal Microbiota Impacts Offspring Immune System

    Data Points

    In this study, scientists compared two populations of pregnant mice, one which was kept germ-free throughout pregnancy and the other which was exposed during pregnancy to a strain of E. coli to determine whether the immune systems of offspring begin to develop in utero. Worksheets also available in Spanish.

  • Virus Hunters: Epidemiology of Nipah Virus

    Virus Hunters: Epidemiology of Nipah Virus

    Case Studies

    In this activity, students will be exploring cases of Nipah virus (NiV) infection as an epidemiologist would, by collecting evidence and making calculations and predictions, based on scientific data.

  • Benefits of Schools

    Benefits of Schools

    Phenomenal Images

    Students explore photos of animals in groups as phenomena to explore animal behavior concepts.

  • Sleep Clears β-amyloid from the Brain

    Sleep Clears β-amyloid from the Brain

    Data Points

    The researchers in this study tested whether the rate of Aβ removal is higher during sleep using mice as model organisms. Worksheets also available in Spanish.

  • Viral Lysis and Budding

    Viral Lysis and Budding

    Labs & Demos

    This activity outlines two demonstrations that model how enveloped and nonenveloped viruses are released from infected cells.

  • HIV Protease Inhibitors

    HIV Protease Inhibitors

    Labs & Demos

    This demonstration models how the HIV protease enzyme functions and how its activity is blocked by a class of anti-HIV drugs.

  • Viral DNA Integration

    Viral DNA Integration

    Labs & Demos

    In this hands-on activity, students model how a double-stranded DNA copy of the HIV genome is integrated into the host cell DNA.

  • HIV Reverse Transcription and AZT

    HIV Reverse Transcription and AZT

    Card Activities

    Students model how the anti-HIV drug AZT (azidothymidine) interferes with the process of viral replication.

  • HIV Receptors and Co-receptors

    HIV Receptors and Co-receptors

    Labs & Demos

    This demonstration models the first step of the HIV life cycle: the binding of HIV envelope proteins to receptors on human helper T cells.

  • Bat Echolocation

    Bat Echolocation

    Data Points

    In this study, researchers tested whether bats change their behavior while hunting based on feedback from echolocation.

  • Patterns of Zoonotic Disease

    Patterns of Zoonotic Disease

    Data Points

    In this study, scientists analyzed previously published data on terrestrial mammal zoonotic host species and the pathogens they carry to search for global patterns of zoonotic disease distribution.

  • Understanding Variation

    Understanding Variation

    Lessons

    This lesson complements the film The Biology of Skin Color and discusses variation in human skin color and polygenic inheritance. Also available in Spanish.

  • Zebrafish and Skin Color

    Zebrafish and Skin Color

    Lessons

    This lesson complements the film The Biology of Skin Color and explores how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color.

  • Thermoregulation in Dinosaurs

    Thermoregulation in Dinosaurs

    Data Points

    Grady and colleagues compared dinosaur fossil evidence with evidence from living animal species to shed more light on the type of thermoregulation that dinosaurs used—ectothermy, endothermy, or mesothermy.
