  • Salt Stress Impacts Photosynthesis in Algae

    Salt Stress Impacts Photosynthesis in Algae

    Data Points

    Scientists investigated how salt affects the photosynthetic electron transport chain in freshwater green alga.

  • 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.

  • Origins of Antibiotic Resistance

    Origins of Antibiotic Resistance

    Data Points

    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.

  • Microbial Community Response to an Oil Spill

    Microbial Community Response to an Oil Spill

    Data Points

    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.

  • Using Wolbachia to Suppress Mosquito Fertility

    Using Wolbachia to Suppress Mosquito Fertility

    Data Points

    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.

  • Bat Echolocation

    Bat Echolocation

    Data Points

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

  • Dating Corn Domestication Using Carbon Isotopes

    Dating Corn Domestication Using Carbon Isotopes

    Data Points

    To study the change in diet as human populations changed lifestyles from hunter-gatherers to agriculturalists, scientists measured carbon isotopes in the collagen tissues of human skeletons from North America.

  • 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.

  • Selective Breeding in Maize

    Selective Breeding in Maize

    Data Points

    Researchers performed the longest-running, controlled artificial selection experiment to study whether they could increase the protein concentration of maize (corn) by selective breeding.

  • Effects of Predation on the Niche of Lizards

    Effects of Predation on the Niche of Lizards

    Data Points

    A team of scientists studied the effects of introducing a lizard predator on the food webs of a group of small islands in the Bahamas.

  • Modeling Ecosystem Effects of Termite Mound Patterns

    Modeling Ecosystem Effects of Termite Mound Patterns

    Data Points

    Dr. Corina Tarnita and colleagues studied how a pattern of termite mounds across a dryland ecosystem enhances resilience against desertification.
