Abstract
Centrosomes act as major microtubule-organizing centers in most cell types. Their functions in interphase and mitosis are usually facilitated by their association with the nucleus. This may be particularly true in very large cells. Several papers report free centrosomes in syncytial Drosophila embryos. However, this phenotype often remains little explored. Yet, free centrosomes can occur by multiple mechanisms, including functional defects of the mitotic spindle, detachment of centrosomes from the nuclear envelope, centrosome inactivation upon DNA damage, and de novo centrosome genesis. Deciphering the cellular mechanism leading to free centrosomes upon a given perturbation such as a mutation or injection of a drug, can provide valuable clues regarding the nature of the molecular pathway affected. To this end, genetic and cytological tests, as well as time-lapse imaging are available. These studies can inform on the biology of centrosomes, cell cycle regulation and cytoskeletal dynamics. Here we briefly discuss what to make of free centrosomes in the fly embryo.

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
