Abstract
Methanococcus maripaludis has two surface appendages, namely flagella and pili. Flagella have been shown to be required for swimming, but no specific role has been assigned as yet to pili. In this report, wild-type M. maripaludis cells are compared with mutants lacking either pili or flagella or both surface appendages in their ability to attach to a variety of surfaces including nickel, gold and molybdenum grids as well as glass, silicon and mica. Wild-type cells attached to varying degrees to all surfaces tested, except mica, via their flagella as observed by scanning electron microscopy. Large cables of flagella were found to leave the cell and to be unwound on the surface. In addition, such cables were often found to connect cells. In contrast, cells lacking either flagella or pili or both surface appendages were unable to attach efficiently to any surfaces. This indicates a second role for flagella in addition to swimming in M. maripaludis, as well as a first role for pili in this organism, namely in surface attachment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
