The memo outlining these new rules has not been made public, but the ban reportedly includes everything from summaries of scientific papers to USDA-branded tweets. Scientists are still able to publish their findings in peer-reviewed journals, but they are unable to talk about that research without prior consent from their agency.
This is not the first time that public science has been hamstrung by a gag order. To this day, the quantity of oil spewed into the ocean during the 2010 Deepwater Horizon Oil spill remains something of a mystery. Many of the scientists who worked on the spill were hired by BP and barred from speaking on it. But gag orders—while always troublesome—have usually been limited to one specific issue. Right now, the EPA and USDA have been forbidden to speak about all of their scientific research. It means that many of the kinds of stories we now cover will never see the light of day.
