Abstract

Toward opioids without poppy fields: Producing opioids without having to depend on field-grown poppies would be of great benefit. Synthetic production could potentially produce more-effective drugs with fewer side effects. Now, Galanie et al. have engineered yeast to produce the opioid compounds thebaine and hydrocodone, starting from sugar (see the Perspective by Nielsen). The amounts produced so far are tiny compared with what would be needed commercially. Future optimization and scaleup are the next challenge. Science , this issue p. 1095 ; see also p. 1050

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.
