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).

    Preventing disastrous offshore spills may require space-program diligence

    As crude oil continues to spew from the Gulf of Mexico seafloor — two weeks now after the Deepwater Horizon accident and sinking — questions continue to surface about what went wrong. To my mind, what went wrong was almost blind optimism on the part of industry, regulators, the states and the public. And any niggling doubt about the wisdom of that optimism was likely assuaged by at least a little greed.

    Gulf oil spill a slow-motion hurricane

    The accident’s timing could determine how badly it damages coastal marshes.

    BP oil rig’s sinking and gushing crude raise questions

    Around 10 p.m. local time on April 20, the Deepwater Horizon — a floating oil-drilling platform leased to British Petroleum — suffered an explosion and fire about 40 miles off the Louisiana coast. While the aftermath of that devastating accident is now being observed and chronicled in painful detail, even the most basic features of what triggered it remain sketchy.

  4. Health & Medicine

    Vitamin D: Obese and ‘uniform’ risks

    Although Vitamin D insufficiency has reached what might be considered epidemic proportions, it’s failed to move onto the radar screens of most physicians, much less consumers. A host of new studies now link excess weight with a deficiency in this, the sunshine vitamin. But that wouldn’t explain why female soldiers become increasing D-ficient during basic combat training. For them, an Army study suggests, the problem may trace to what they wear.

  5. Health & Medicine

    Chili pepper holds hot prospects for painfree dieting

    A cousin of the chemical that packs the heat in chilis not only can rev up the body’s metabolism but actually encourage it to preferentially burn fat, according to a new trial in obese men and women. And the kicker: The molecule is itself so fat that it can’t fit into the receptors that would ordinarily register pain.

  6. Health & Medicine

    This off-white rice may be heart healthy

    The outer coating of a semi-polished rice – a layer which manufacturers ordinarily polish off of brown rice in the process of making it white – offers cardiovascular benefits, new data indicate.

  7. Health & Medicine

    Baby’s calcium might play defining role in adult bone health

    Calcium makes bones strong. But a new animal study suggests that to do this, ample calcium may need to be available from birth. Too little in the early weeks of life may reprogram certain stem cells – those in the marrow – in ways that permanently compromise bone structure. Perhaps even fostering osteoporosis.

    Women of childbearing age still aren’t getting enough folic acid

    To head off a risk of neural tube defects, a class of potentially devastating birth defects, women of childbearing age are supposed to get at least 400 micrograms of folic acid daily. A government study now finds that the vast majority of these women fall short. It finds that the national average for women in this age group is some 40 percent below the recommended minimum.

  9. Health & Medicine

    Data from many drug trials for stroke go unpublished

    Important details from roughly one in five drug trials for the acute treatment of the most common type of stroke have never entered the public domain, a new study finds. The masked data come from 125 trials that tested effects of 89 different drugs.

  10. Agriculture

    Rural ozone can be fed by feed (as in silage)

    Livestock operations take a lot of flak for polluting. Researchers are now linking ozone to livestock, at least in one of the nation's most agriculturally intense centers. And here the pollution source is not what comes out the back end of an animal but what’s destined to go in the front.

  11. Earth

    Studies aim to resolve confusion over mercury risks from fish

    Several new papers suggest strategies by which American diners can negotiate a mercury minefield to tap dietary benefits in fish.

    IOM: Manufacturers should help Americans cut back on salt

    Americans have developed an unhealthy love affair with this savory condiment. And 40 years of haranguing people about their overconsumption has “generally failed to make a dent in Americans’ intake,” according to the Institute of Medicine, a research arm of the National Academy of Sciences. A new report it releases April 21 will ask the Food and Drug Administration to set lower ceilings on how much salt can be added to processed foods.
