Kathryn Hulick is the author of Strange But True: 10 of the World's Greatest Mysteries Explained, about the science behind paranormal mysteries, including ghosts, aliens, sea monsters and more. A sequel about the future of technology comes out in 2020. Hulick also writes regularly for Science News for Students and Muse magazine.


Her favorite part of writing about science is getting to speak with researchers in many different fields. Once, she spoke with an expert on parallel universes while he was shoveling snow from his driveway.

All Stories by Kathryn Hulick

  1. Animals

    Do dogs have a sense of self?

    Dogs don’t know their own reflections in a mirror, but they do recognize themselves from the scent of their own urine, a new study finds.

  2. Animals

    Some otters wear red algae

    Some sea otters in California sport coats of red algae. A new study finds the species most likely is a non-native organism from half a world away.

  3. Tech

    Engineers consider liquid salt to generate power

    A new type of power plant, a molten salt reactor, might provide electricity in a cleaner and safer way than current nuclear technology.

  4. Chemistry

    Some 3-D printing can leave toxic taint

    The ”ink” inside some 3-D printers can leave toxic traces. In tests, these chemicals harmed baby fish. But lighting could render the parts safer.

  5. Microbes

    Slime cities

    Biofilms are like tiny cities of bacteria — some harmless, others destructive. Scientists are learning how to keep these microscopic metropolises under control.

  6. Animals

    Rare as a rhino

    Most species are rare. Some have always been rare. A problem develops when people are responsible for accelerating a species’ rarity to the point that extinction threatens.

  7. Physics

    X-ray ‘eyes’

    Movie directors often make “short” subjects, flicks running sometimes just a few minutes or so. But scientists have begun making much quicker “shorts,” essentially nanofilms. Their goal: catching science in action.
