Staff Writer, Biological Sciences

Meghan Rosen is a staff writer who reports on the life sciences for Science News. She earned a Ph.D. in biochemistry and molecular biology with an emphasis in biotechnology from the University of California, Davis, and later graduated from the science communication program at UC Santa Cruz. Prior to joining Science News in 2022, she was a media relations manager at the Howard Hughes Medical Institute. Her work has appeared in Wired, Science, and The Washington Post, among other outlets. Once for McSweeney’s, she wrote about her kids’ habit of handing her trash, a story that still makes her (and them) laugh.

  1. Tech

    Lasers heal damaged rodent teeth

    Handheld laser spurs stem cells into action, regrowing dentin in drilled teeth.

  2. Tech

    Coffee beans sing distinct tune

    Measuring the crackling noises made by roasting coffee beans could help engineers create automatic acoustic roasters.

  3. Health & Medicine

    Parasite protein offers new hope for malaria vaccine

    A newly discovered malarial protein triggers the immune system to trap disease-causing parasites in red blood cells. The protein offers scientists a promising target for vaccines.

  4. Animals

    Lizards may scale back head bobbing to avoid predators

    Brown anoles may scale back mating signals to avoid being eaten.

  5. Earth

    Tiny earthquakes may follow groundwater loss

    Draining California’s aquifers may stress San Andreas Fault, triggering earthquakes and forcing mountains to rise.

  6. Neuroscience

    Birth of new brain cells might erase babies’ memories

    The growth of new neurons in early childhood may explain why adults can’t remember being infants.

  7. Planetary Science

    The ice of a distant moon

    Jupiter’s moon Europa hides a liquid ocean, and conceivably life, under kilometers of ice. The challenge for engineers is how to penetrate that frozen barrier with technology that can be launched into space and operated remotely.

  8. Neuroscience

    Humans can sniff out gender

    A new study adds to controversy of whether people have pheromones.

  9. Chemistry

    Color-changing polymer maps fingerprints

    Tiny beads of sweat may offer new way to identify people’s fingerprints.

  10. Paleontology

    ‘Hidden dragon’ fossil is oldest flying reptile

    Researchers have unearthed the oldest pterodactyl ever discovered: Kptodrakon progenitor soared over the Earth 163 million years ago.

  11. Planetary Science

    Mountains on Saturn moon may have come from space

    A mountainous ridge around the equator of Iapetus, one of Saturn’s moons, may have formed from cosmic debris.

  12. Climate

    Reef fish act drunk in carbon dioxide–rich ocean waters

    In first test in the wild, fish near reefs that bubble with CO2 lose fear of predators’ scent.
