Meghan Rosen

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.

All Stories by Meghan Rosen

  1. Life

    Dinos straddled line between cold- and warm-blooded

    Tyrannosaurus rex and other dinosaurs straddled line between cold- and warm-blood, a new analysis finds.

  2. Paleontology

    Preserved pterosaur eggs hint at reptile’s social life

    The first 3-D pterosaur eggs, which were found in China, suggest that the flying reptiles laid eggs together.

  3. Planetary Science

    Moon’s origins revealed in rocks’ chemistry

    A new chemical measurement of rocks from Earth and from the moon supports the giant impact hypothesis, which explains how the moon formed billions of years ago.

  4. Life

    Drug candidate takes new aim at MERS

    An experimental drug that shuts down construction of virus-making factories could become a new weapon against MERS.

  5. Tech

    Lasers heal damaged rodent teeth

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

  6. Tech

    Coffee beans sing distinct tune

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

  7. 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.

  8. Animals

    Lizards may scale back head bobbing to avoid predators

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

  9. Earth

    Tiny earthquakes may follow groundwater loss

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

  10. 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.

  11. 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.

  12. Neuroscience

    Humans can sniff out gender

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