  • The Search for a Mutated Gene

    The Search for a Mutated Gene

    Scientists at Work

    (8 min 54 sec) How do you identify the disease-causing mutation in a patient with an inherited disease? This video illustrates the steps involved—testing for genes that are the “usual suspects,” searching for mutations in novel genes, and assessing links between genotype and phenotype.

  • Mosquitoes Might SAVE Lives, Thanks To Bacteria

    Mosquitoes Might SAVE Lives, Thanks To Bacteria

    Feature Film

    (9 min 4 sec) Dengue fever is a deadly mosquito-borne virus that plagues the earth, but science is inching closer to an unlikely solution: bacteria.

  • Genes as Medicine

    Genes as Medicine

    Short Film

    (17 min 16 sec) Watch the story of how gene therapy restored the sight of a nearly-blind young patient. Told from the perspective of two researchers who spent over 25 years working to develop this breakthrough technology, this short film chronicles their successes and challenges, and illustrates how the method works to treat inherited conditions.

  • Origins of Antibiotic Resistance

    Origins of Antibiotic Resistance

    Data Point

    Scientists collected bacteria from locations that had never been exposed to humans or modern antibiotics to determine if antibiotic resistance is newly evolved since the introduction of antibiotics or has evolved independently.

  • Identifying the Key Genes for Regeneration

    Identifying the Key Genes for Regeneration

    Scientists at Work

    (9 min 55 sec) Planarians have an amazing ability to regenerate lost tissues. In this video, scientists knock out two different genes in planaria to start to understand how the process works—and they generate animals with two heads and two tails!

  • Vertebrate Declines and the Sixth Mass Extinction

    Vertebrate Declines and the Sixth Mass Extinction

    Data Point

    In this study, researchers measured species population declines on a global scale that may contribute to the sixth mass extinction.

  • Virus Hunters: Epidemiology of Nipah Virus

    Virus Hunters: Epidemiology of Nipah Virus

    Activity

    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.

  • Central Dogma and Genetic Medicine

    Central Dogma and Genetic Medicine

    Click & Learn

    This interactive uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat genetic diseases.

  • What van Leeuwenhoek Saw

    What van Leeuwenhoek Saw

    Activity

    This hands-on activity helps students understand concepts related to building scale models by using cards of microorganisms and cells that were first visualized by Antonie van Leeuwenhoek.

  • Predator-Prey Relationship Dynamics

    Predator-Prey Relationship Dynamics

    Data Point

    In a study in Greenland, scientists examined whether changes in population densities of Arctic fox are related to changes in population densities of its main prey, the lemming.

  • Tracking Genetically Modified Mosquitoes

    Tracking Genetically Modified Mosquitoes

    Activity

    Genetically modified mosquitoes have been used to reduce mosquito populations and the diseases they spread. But how can we tell if the method works? In this activity, students analyze data from a field experiment.

  • Microbial Community Response to an Oil Spill

    Microbial Community Response to an Oil Spill

    Data Point

    Researchers monitored the succession of the microbial community in the Gulf of Mexico using data from before, during, and after the Deepwater Horizon oil spill.

  • Population Dynamics

    Population Dynamics

    Click & Learn

    Explore the exponential and the logistic growth mathematical models that describe how population changes with time.

  • Using Wolbachia to Suppress Mosquito Fertility

    Using Wolbachia to Suppress Mosquito Fertility

    Data Point

    In this study, researchers tested whether releasing Wolbachia-infected male Aedes albopictus (Asian tiger mosquitoes) would suppress populations of this mosquito species in their study area.

  • How Lizards Find Their Way Home

    How Lizards Find Their Way Home

    Scientists at Work

    (8 min 33 sec) When Dr. Manuel Leal removed lizards from an area in the forest, he noticed an interesting phenomenon: all the lizards seemed to be back the next day. Watch as he sets up an experiment to study how these lizards navigate home. Also available in Spanish.

  • WildCam Darién

    WildCam Darién

    Click & Learn

    Researchers in Darién and Soberanía National Parks use remote trail cameras to study jaguars and their prey. You can contribute to this important research through WildCam Darién, an online citizen science platform.

  • 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.

  • Trophic Cascades in Salt Marsh Ecosystems

    Trophic Cascades in Salt Marsh Ecosystems

    Scientists at Work

    (10 min 1 sec) Ecologist Brian Silliman uses manipulative field experiments to reveal that salt marsh ecosystems are under top down control from consumers and predators.

  • Riverine Food Webs – How Flow Rates Affect Biomass

    Riverine Food Webs – How Flow Rates Affect Biomass

    Scientists at Work

    (9 min 15 sec) Ecologist Mary Power studies the Eel River in Northern California to figure out the connection between river flows and biodiversity.

  • Mimicry in a Diverse Community of Arthropods

    Mimicry in a Diverse Community of Arthropods

    Data Point

    Researchers exposed arthropod mimics that use a golden patch to warn of unpalatability to predators with different prey preferences to determine how effective their warnings were.
