Comment on “A Bacterium That Can Grow by Using Arsenic Instead of Phosphorus”
Abstract
Wolfe-Simon et al . (Research Articles, 3 June 2011, p. 1163; published online 2 December 2010) reported that the bacterial strain GFAJ-1 can grow by using arsenic (As) instead of phosphorus (P), noting that the P content in bacteria grown in +As/–P culture medium was far below the quantity needed to support growth. However, low P content is a common phenotype across a broad range of environmental bacteria that experience P limitation.

In the citing paper
“These claims have been largely rejected by the scientific community, which has generally concluded that they are not proven by the evidence presented in the paper (Benner, 2011; Borhani, 2011; Cotner and Hall, 2011; Csabai and Szathmáry, 2011; Foster, 2011; Oehler, 2011; Redfield, 2011; Schoepp-Cothenet et al., 2011; Erb et al., 2012; Reaves et al., 2012).”

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.
