Abstract
Mitochondrial function is central to longevity and an imbalance in mitonuclear protein homeostasis activates a protective response called the mitochondrial unfolded protein response (UPRmt). Toxic compounds damaging mitochondria trigger the UPRmt, but at sublethal doses these insults extend lifespan in simple animals like C. elegans. Mitochondria are the main energy suppliers in eukaryotes, but it is not known if diet influences the UPRmt. High dietary glucose reduces lifespan in worms, and we show that high dietary glucose activates the UPRmt to protect against lifespan reduction. While lifelong exposure to glucose reduces lifespan, glucose exposure restricted to developing animals extends lifespan and requires the UPRmt. However, this lifespan extension is abolished by further mitochondrial stress in adult animals. We demonstrate that dietary conditions regulate mitochondrial homeostasis, where induction of the UPRmt during development extends lifespan, but prolonged activation into adulthood reduces lifespan.

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
