Time was when American opera companies considered musicals as suspect artifacts from another planet, hardly worthy of serious attention -- not even on a par with the operettas those companies would occasionally stage when they needed a box office lift.
Public health officials can work closely with those who have handled any suspect artifacts, determine risks, help mitigate concern, and arrange for appropriate testing.
Despite the merits of exact replications, however, they cannot uncover artifacts in the original protocol that may produce false positive results, whereas suitably modified replications can do exactly that by showing that an experiment fails when a suspected artifact is controlled for.
10 P.M. (13) QUEST FOR THE LOST MAYA Archaeologists explore sites in Mexico that they suspect hold artifacts from a fallen empire, and they discover evidence that Mayan society on the Yucat Peninsula was present centuries earlier than originally believed.
Although the artifacts were reportedly from the same layer as Neandertal fossils, many researchers suspected that artifacts and bones from different layers got mixed up in the investigation, as dating expert Thomas Higham of the University of Oxford in the United Kingdom suggested in 2010.
Skeptics had suspected that artifacts of more recent vintage had somehow intruded into the cave's lower and thus older sediments.
Such losses of channel genes in animal lineages may be suspected as artifacts due to technical reasons, such as errors in gene annotation, genome assembly, and/or insufficient sequencing depth.
After filtering out 381 (of 2828) repetitive overgo probes that hit more than 30 BACs in the GR library, and 357 BACs (out of 34,713 BACs with at least one marker hit) with more than 8 markers hybridized as suspected hybridization artifacts, the remaining probes and BACs produced 40,152 BAC-probe pairs.
Retrospective review of the EUS images from the false-positive case showed a suspected echo artifact.
Suspecting an artifact due to long-branch attraction (LBA; Brinkmann et al. 2005), we reanalyzed our data set after discarding the cyanobacterial outgroup and all complex algae, except the three most slowly evolving stramenopiles (supplementary fig. S2 b, Supplementary Material online).
I suspect that this artifact may not be large enough to explain all of the results in this manuscript, but the authors need to consider it.
