Janet Raloff

Editor, Digital, Science News Explores

Editor Janet Raloff has been a part of the Science News Media Group since 1977. While a staff writer at Science News, she covered the environment, toxicology, energy, science policy, agriculture and nutrition. She was among the first to give national visibility to such issues as electromagnetic pulse weaponry and hormone-mimicking pollutants, and was the first anywhere to report on the widespread tainting of streams and groundwater sources with pharmaceuticals. A founding board member of the Society of Environmental Journalists, her writing has won awards from groups including the National Association of Science Writers. In July 2007, while still writing for Science News, Janet took over Science News Explores (then known as Science News for Kids) as a part-time responsibility. Over the next six years, she expanded the magazine's depth, breadth and publication cycle. Since 2013, she also oversaw an expansion of its staffing from three part-timers to a full-time staff of four and a freelance staff of some 35 other writers and editors. Before joining Science News, Janet was managing editor of Energy Research Reports (outside Boston), a staff writer at Chemistry (an American Chemical Society magazine) and a writer/editor for Chicago's Adler Planetarium. Initially an astronomy major, she earned undergraduate and graduate degrees from the Medill School of Journalism at Northwestern University (with an elective major in physics).

    Blood markers of clogging arteries emerge

    The concentration in blood of one chemically transformed cholesterol-carrying molecule may signal to doctors when a patient's heart disease has dangerously worsened.

  2. Anticancer mineral works best in food

    Selenium's anticancer benefits may depend on ingestion of the mineral in food, not as a purified dietary supplement.

  3. Keeping antioxidants may spare gut

    Inflammatory bowel disease may initially be triggered by chemical reactions that deplete affected tissues of a key antioxidant.

  4. Pulling antioxidants starves cancers

    Realizing that many cancers depend on antioxidants for their survival, researchers have successfully designed a dietary strategy that suppresses breast cancer growth and spread, at least in animals.

  5. Cigarette smoke worsens heart attacks

    Breathing in smoke from another person's cigarette causes blood changes that reduce the likelihood that an individual will survive a heart attack.

    Toxic runoff from plastic mulch

    By laying sheets of plastic across their fields, farmers can bring crops to market faster while reducing their vulnerability to many blights (SN: 12/13/97, p. 376). On the negative side, however, this polymer mulch creates impermeable surfaces over more than half of a planted field. That significantly increases the amount of rain and pesticides that […]

    Boosting Boron Could Be Healthful

    Largely ignored so far, dietary boron may play important roles in preventing diseases such as arthritis and prostate cancer.

  8. Gene therapy won’t replace Viagra—yet

    Vitamin E targets dangerous inflammation

    People with diabetes face a high risk of heart attack and stroke. One apparent culprit is the chronic, low-grade inflammation that they develop. Megadoses of vitamin E can dramatically reduce that inflammation, a new study finds. Ishwarlal Jialal and Sridevi Devaraj of the University of Texas Southwestern Medical Center at Dallas studied 47 men and […]

    Optical biopsy hunts would-be cancers

    A new optical tool allows physicians to scout for precancerous tissue by analyzing the fluorescent responses of cells when light is shone on them.
