We’re celebrating Earth Day by looking inward — way inward. What looks like coral? A gut organoid. A swirling galaxy? A zebrafish heart, no bigger than a strand of hair. A star map? Neuron-glia crosstalk. These images don’t come from the deep sea or the cosmos — they come from labs where scientists are working to understand how life grows, heals and adapts at the tiniest scales. At CZI, we are exploring these inner worlds — advancing imaging, modeling and biotech to unlock discoveries that can transform health and protect life at every level. #EarthDay2025 #Microscopy #Science #Neuroscience #Biotech #Imaging #CellBiology
