  • Age Structure of Ebola Outbreaks

    Age Structure of Ebola Outbreaks

    Data Point

    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 Point

    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 Point

    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.

  • Benefits of Schools

    Benefits of Schools

    Phenomenal Image

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

  • Sleep Clears β-amyloid from the Brain

    Sleep Clears β-amyloid from the Brain

    Data Point

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

  • Bat Echolocation

    Bat Echolocation

    Data Point

    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 Point

    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

    Activity

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

  • Thermoregulation in Dinosaurs

    Thermoregulation in Dinosaurs

    Data Point

    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.

  • Alzheimer’s Disease: Piecing Together the Evidence

    Alzheimer’s Disease: Piecing Together the Evidence

    Click & Learn

    This interactive explores evidence from brain anatomy, tissue histology, and genetic studies to reveal possible targets for the treatment of Alzheimer’s disease.

  • Origin of a Gene Mutation Causing Early-Onset Alzheimer’s Disease

    Origin of a Gene Mutation Causing Early-Onset Alzheimer’s Disease

    Data Point

    A team of scientists built a pedigree of a large extended family in Antioquia, Colombia, that has a high prevalence of early-onset familial Alzheimer’s disease due to a mutation in the PSEN1 gene. Worksheets also available in Spanish.

  • Amylase Copy Number and Diet

    Amylase Copy Number and Diet

    Data Point

    A team of scientists investigated whether there is a correlation between the number of AMY1 gene copies and the type of diet (high-starch or low-starch) of a population.

  • Genetic Origin of Variation in Human Skin Color

    Genetic Origin of Variation in Human Skin Color

    Data Point

    Dr. Rebecca Lamason and colleagues studied the genetic origin of variation in human skin color using a model organism, the zebrafish.

  • Human Skin Color: Evidence for Selection

    Human Skin Color: Evidence for Selection

    Activity

    This case study is based on the short film The Biology of Skin Color. Students use real data to propose hypotheses, make predictions, and justify claims with evidence. Also available in Spanish.

  • The Origin of Flight: What Use Is Half a Wing?

    The Origin of Flight: What Use Is Half a Wing?

    Scientists at Work

    (8 min 16 sec) Biologist Ken Dial's study of how young birds use their developing wings sheds light on the evolution of flight in birds.

  • Film Guide for The Biology of Skin Color

    Film Guide for The Biology of Skin Color

    Film Guide

    The following classroom-ready resources complement The Biology of Skin Color. Featuring anthropologist Dr. Nina Jablonski, the film walks us through the evidence that differences in human skin color are adaptations to varying intensity of UV light. Also available in Spanish.

  • Schooling Behavior of Stickleback Fish from Different Habitats

    Schooling Behavior of Stickleback Fish from Different Habitats

    Data Point

    A team of scientists studied the schooling behavior of threespine stickleback fish by experimentally testing how individual fish responded to an artificial fish school model.

  • How Did Dinosaurs Regulate Their Body Temperature?

    How Did Dinosaurs Regulate Their Body Temperature?

    Activity

    This activity uses data from a 2014 scientific paper to explore thermoregulation in living and extinct animals, including dinosaurs. 

  • The Biology of Skin Color

    The Biology of Skin Color

    Short Film

    (18 min 58 sec) Penn State University anthropologist Dr. Nina Jablonski walks us through the evidence that the different shades of skin color among human populations arose as adaptations to the intensity of ultraviolet radiation in different parts of the world. Also available in Spanish.

  • Milk—How Sweet Is It?

    Milk—How Sweet Is It?

    Activity

    In this lab, students test different samples to see which ones contain the lactase enzyme. Also available in Spanish.
