All Stories by Katie Grace Carpenter

  1. Plants

    Scientists Say: Fertilize

    This word describes both a stage of sexual reproduction and the agricultural practice of adding nutrients to soil.

  2. Humans

    Scientists Say: Prehistoric

    Researchers rely on prehistoric tools and other artifacts to study the vast stretches of time before recorded history.

  3. Animals

    Scientists Say: Vertebrate

    Animals with spines, or vertebrates, come in all shapes and sizes.

  4. Chemistry

    Scientists Say: Lignin

    This rigid polymer transports water and gives trees their strength.

  5. Math

    Scientists Say: Imaginary Number

    These numbers may not be “real,” but they sure aren’t make-believe.

  6. Tech

    Scientists Say: Robot

    These task-doers handle jobs as simple as vacuuming the floor and as complex as navigating extraterrestrial terrains.

  7. Tech

    A puff of air could deliver vaccines needle-free

    A new Nerf gun-like device may make injections safer, faster and easier.

  8. Life

    Scientists Say: Mycelium

    These fibrous networks are the reason plants think fungi are such "fun guys.”

  9. Tech

    This electronic bandage sterilizes wounds with flashes of light

    Dentists have sterilized medical equipment with ultraviolet-C light for years. Applying this tech to bandages had proven a challenge — until now.

  10. Psychology

    Scientists Say: Neurodivergent

    This often-misunderstood word describes someone whose brain works a little differently from most.

  11. Chemistry

    Scientists Say: Valence electrons

    These far-out electrons do the hard work when it comes to chemical reactions.

  12. Ecosystems

    Scientists Say: Predator and Prey

    Ecological relationships between predators and their prey drive the evolution of plants, animals and microbes.
