38 5 Full Breakdown

Summary

Story summary

A new study shows comb jellies have a centralized aboral organ that coordinates behavior by sensing gravity, pressure changes, and light.
Researchers report the aboral organ comprises about 900 cells and 17 distinct cell types, 11 new to science.
Using advanced imaging, the team mapped the AO's structure, and the findings imply centralized nervous systems may have evolved earlier and across different species, published in Science Advances.
