Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • When shocked with a steel projectile fired at high velocities in a light gas gun, ice mixtures made of NH4OH, CO2 and CH3OH were found to produce equal amounts of (R)- and (S)-alanine, alpha-aminoisobutyric acid and isovaline as well as their precursors.

  • Only the impact shock is responsible for the formation of amino-acids because post-shot heating is not sufficient.

    “Importantly, only the impact shock is responsible for the formation of amino-acids because post-shot heating is not sufficient.”
  • Price and Furukawa teams reported in 2013 and 2015 that nucleobases and/or proteinogenic amino acids were formed under conditions which presumably reproduced the conditions of impact of celestial bodies on primitive earth.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
