All Stories by Katie Grace Carpenter

  1. Math

    Scientists Say: Imaginary Number

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

  2. Tech

    Scientists Say: Robot

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

  3. Tech

    A puff of air could deliver vaccines needle-free

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

  4. Life

    Scientists Say: Mycelium

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

  5. 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.

  6. Psychology

    Scientists Say: Neurodivergent

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

  7. Chemistry

    Scientists Say: Valence electrons

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

  8. Ecosystems

    Scientists Say: Predator and Prey

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

  9. Animals

    Scientists Say: Coral

    Over 4,000 species of fish make their home among the reefs created by these colony-dwelling marine animals.

  10. Math

    Scientists Say: Ellipse

    Ellipse describes the shapes of planetary orbits around their stars and explains the wacky acoustic phenomenon of “whispering chambers.”

  11. Brain

    Scientists Say: Addiction

    Recovering from addiction is hard but possible. Encouragement of loved ones can improve a person’s chances of overcoming this disease.

  12. Tech

    Nanocrystal ‘painted’ films may someday help relieve summer heat

    The rainbow palette and cooling powers of new plant-based films comes from their microscopic surface patterns of tiny crystals.
