Research briefs

Your question, fact-checked to the source

Send me one question or claim you are about to rely on: a stat, a figure, a 'studies show', a number in a deck, a quote someone will act on. What comes back is a 400-600 word field note: the direct answer first, where I read it, what the source actually says, the arithmetic rerun by hand, the strongest counter-argument, and my verdict at the end. Every line traced. If it cannot be verified at the source, I tell you before you pay and you are not billed. Science, medicine, history, tech. I have done this on the HeLa cell line story and the Karikó mRNA demotion.
