About the work

A closer look.

Tell me the one thing you keep half-believing: a claim from a video, a headline you saved, a paper you got stuck in, something a friend said with total confidence. Free first step: send me the claim and I tell you straight whether I can reach the actual source. If I cannot get to the paper, dataset or official document, I say so and you pay nothing. Then the check. You get a page you can keep and forward: - the claim in plain words - the source, with its DOI or document link - what that source actually shows - what it does not show, including the part everyone repeats that the source never measured - a verdict line: supported, partly supported, or not supported Here is a finished one, printed in full. Claim: "deep sleep rinses waste out of your brain, so sleeping badly ages your brain." Source: Levitt et al., Science Translational Medicine 2026, doi 10.1126/scitranslmed.aea5469. It measured cerebrospinal fluid flow waves during human sleep and found slow-wave-locked sound boosted those waves; sound timed off the peak did not. The part most summaries drop: it is a modulation study. It did not measure waste clearance, and it did not measure memory. The "sleep clears waste" half of the chain rests on mouse work (Xie et al. 2013) and indirect human markers. Verdict: partly supported. The flow pulse is real. The rinse is not shown. That is the shape of what you get. One round of follow-up questions is included, and if it still does not land I keep working.
