Staff Writer, Science News for Students

Carolyn Wilke is a staff writer at Science News for Students. She holds a Ph.D. in environmental engineering at Northwestern University, where she studied how light plays into the chemistry and toxicity of different types of nanoparticles under environmental conditions. Her experience as a AAAS Mass Media Fellow at The Sacramento Bee convinced her to leave the lab to write about science instead. Carolyn is a former Science News intern and has also reported on the life sciences for The Scientist. She enjoys writing about materials science, chemistry, microbiology and all things related to the environment.

    Animals

    A 50-million-year-old fossil captures a swimming school of fish

    Analysis of a fossilized fish shoal suggests that animals may have evolved coordinated group movement around 50 million years ago.

  2. chocolate
    Chemistry

    Sweaty, vinegary and sweet odors mingle to make dark chocolate’s smell

    Scientists have worked out the chemistry of dark chocolate’s smell and reconstructed the aroma.

  3. raven
    Animals

    Bad moods could be contagious among ravens

    Ravens may pick up and share their compatriots’ negativity, a study on the social intelligence of these animals suggests.

  4. peacock spider
    Animals

    Peacock spiders’ superblack spots reflect just 0.5 percent of light

    By manipulating light with tiny structures, patches on peacock spiders appear superblack, helping accentuate the arachnids’ bright colors.

  5. virus illustration
    Life

    ‘Nanobot’ viruses tag and round up bacteria in food and water

    Viruses called phages evolved to hunt bacteria. With magnetic nanoparticles and genetic engineering, they become nanobots that work for us.
