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).

    Coffee perks up memory and balance in geriatric animals

    Millions of Americans start their day with a cup of coffee and then reach for refills when their energy or attention flags. But new research in rats suggests that for the aging brain, coffee may serve as more than a mere stimulant. It can boost memory and the signaling essential to motor coordination.

    Good vibrations: A greener way to pasteurize milk

    Many people like the taste of raw – as in unpasteurized – milk. The problem, of course, is that germs may infect raw milk, so food safety regulations require that commercial producers heat-treat their milk. But food scientists at Louisiana State University think they’ve stumbled onto a tastier way to sterilize milk. They bombard it with sound waves.

    Nano-scale additives fight food pathogens

    Nano products are all the rage, even in food science. Here at the Institute of Food Technologists’ annual meeting, on July 18, scientists described dramatic success in fighting food-poisoning bacteria by doctoring foods or their packaging with microbe-killing nanoparticles – sometimes along with natural anti-bacterial agents.

  4. Agriculture

    Germs eyed to make foods safer

    Adding viruses to foods doesn’t sound appetizing, much less healthy. But it’s a stratagem being explored to knock some of the more virulent food poisoning bacteria out of the U.S. food supply. Scientists described data supporting the tactic July 18 at the Institute of Food Technologists’ annual meeting in Chicago.

  5. The incredible shrinking solar cell

    With lilliputian collectors, almost anything could be sun-powered.

    Body shape may affect mental acuity

    Among women 65 to 79, big apples performed better than plump pears on tests of memory and reasoning.

    What Jefferson was thinking

    Imaging technology reveals a last-minute revision to the Declaration of Independence.

    Fructose sweeteners may hike blood pressure

    The more fructose American adults add to their diets, the higher their blood pressure tends to be. The new finding adds fuel to a simmering controversy about whether this simple sugar — found in fruits, table sugar, soft drinks and many baked goods — poses a health hazard that goes beyond simply consuming too many empty calories.

    Breast screening tool finds many missed cancers

    A relatively new imaging option outperforms all comers in scouting for hidden breast tumors. Indeed, argues radiologist Rachel Brem, her team’s new data indicate that that “almost 10 percent of women with breast cancer have another [tumor] that we wouldn’t know about without this technology.”

    Ivy nanoparticles promise sunblocks and other green products

    I’ve developed a love-hate relationship with English ivy that’s been devolving towards hate-hate. But a new paper may temper my antipathy. Apparently this backyard bully also offers a kinder, gentler alternative to the potentially toxic metal-based nanoparticles used in today’s sunscreens.

    How resveratrol (in grapes, peanuts and wine) fights fat and disease

    Resveratrol, a constituent of grapes and certain other plants, can fight the proliferation of fat cells and improve the uptake of sugar from the blood, a pair of new studies indicate. These observations offer some mechanisms to explain why grape products, including wine, have developed a reputation as heart healthy, obesity-fighting and beneficial for people developing diabetes.

    Abuse of pharmaceuticals is rising sharply

    In 2008, the most recent year for which data are available, an estimated 1 million Americans entered a hospital emergency room for treatment of an overdose due to “nonmedical” use of an over-the-counter or prescription drug. That’s double the number of such visits five years earlier, federal data show.
