Abstract
Lipid droplets are ubiquitous cellular structures involved in energy homeostasis and metabolism that have long been considered as simple inert deposits of lipid. Here, we show that lipid droplets are bona fide organelles that are actively partitioned between mother cell and daughter cell in Saccharomyces cerevisiae. Video microscopy revealed that a subset of lipid droplets moves from mother cell to bud in an ordered, vectorial process, while the remaining lipid droplets are retained by the mother cell. Bud-directed movement of lipid droplets is mediated by the molecular motor Myo2p, while retention of lipid droplets occurs at the perinuclear endoplasmic reticulum. Lipid droplets are thus apportioned between mother cell and daughter cell at cell division rather than being made anew.

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
