Abstract
Jellyfish have been drifting around the planet for more than 500 million years, yet relatively little is known about their lifestyles. Now, scientists at the University of British Columbia’s Institute for the Oceans and Fisheries are using biochemical tools to unravel a key part of the jellyfish mystery: their diet ( J. Exp. Mar. Biol. Ecol. 2021, DOI: 10.1016/j.jembe.2021.151631 ). Scientists frequently use the unique stable isotope and fatty acid signatures present in living things to investigate what predators eat. To calibrate these values for jellyfish, the team, led by Jessica Schaub, performed controlled feeding experiments at the Vancouver Aquarium. Docile moon jellies were fed frozen brine shrimp, which they unexpectedly rejected, and live krill. Voracious Japanese sea nettle jellies were fed frozen brine shrimp and the moon jellies. After analyzing the isotope and fatty acid signatures, the researchers were surprised to find that jellyfish appear to biosynthesize their own

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
