Senior Writer

Meghan Rosen is a senior 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. Her dissertation work involved studying mutated proteins in liver and kidney cancer. She 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. Health & Medicine

    Cancer uses mitochondria to reprogram neighboring cells

    Cancer cells transfer mitochondria through nanotubes to healthy neighboring cells, turning them into tumor-supporting accomplices, a new study shows.

  2. Animals

    This ‘ghost shark’ has teeth on its forehead

    Spotted ratfish, or “ghost sharks,” have forehead teeth that help them grasp onto mates. It’s the first time teeth have been found outside of a mouth.

  3. Humans

    Staying on the keto diet long term could carry health risks

    Months on a high-fat keto diet put mice at risk for cardiovascular disease and impaired insulin secretion.

  4. Health & Medicine

    Cancer patients froze reproductive tissue as kids. Now they’re coming back for it

    Saving reproductive tissue from kids treated for cancer before adolescence could give them a chance at having biological children later in life.

  5. Humans

    Want to avoid mosquito bites? Step away from the beer

    A Dutch music festival turned into a mosquito lab, revealing how beer, weed, sleep and sunscreen affect your bite appeal.

  6. Health & Medicine

    Drugs like Ozempic might lower cancer risk

    GLP-1 medications like Ozempic, Wegovy and Mounjaro might lower people’s risk of developing certain cancers, especially ones linked to obesity.

  7. Animals

    Here’s how fruit flies’ giant sperm squeeze into tight spaces

    Researchers found that fruit fly sperm push against one another and align in orderly bundles, preventing knots that could block reproduction.

  8. Animals

    This lizard can tolerate extreme levels of lead

    Cuban brown anoles have the highest blood lead levels of any vertebrate known — three times that of the previous record holder, the Nile crocodile.

  9. Health & Medicine

    mRNA vaccines hold promise for many diseases. Now the tech is under fire 

    Researchers warn that halting federal contracts for mRNA vaccine research could weaken pandemic preparedness and slow medical advances.

  10. Health & Medicine

    AI is designing proteins that could help treat cancer

    A team used generative AI to enhance T cells’ ability to fight melanoma. The immunotherapy approach needs more testing before use in cancer patients.

  11. Health & Medicine

    An injected gel could make drugs like Ozempic last longer

    GLP-1 drugs for diabetes and weight loss are difficult for some people to inject weekly. A new slow-release gel, tested in rats, could help.

  12. Life

    This killer fungus strikes at sunset. Here’s how

    The fungus Entomophthora muscae turns flies into zombies and kills them at sunset. An internal kill clock may explain the mysterious timing.
