Osaka University researchers elucidated the molecular details of how Drosophila larval epidermal cells (LECs) undergo cell death in a controlled manner to regulate epithelial tissue remodeling. Specifically, lower activation of the epidermal growth factor receptor (EGFR) signaling pathway occurs following reduced endocytosis. Decreased EGFR pathway activity allows LECs to switch from undergoing single-cell apoptosis to more widespread cell death in clusters. This supports faster LEC elimination and allows for proper tissue remodeling.

Through lipidomic and proteomic analyses, this study reveals how the Mariana Trench snailfish adapts to extreme deep-sea conditions. Findings highlight the fish’s unique lipid regulation, energy storage, and antioxidant mechanisms that enable survival under high pressure and low temperatures.

Coral larvae reduce their metabolism and increase nitrogen uptake to resist bleaching in high temperatures, according to a study published November 12^th in the open-access journal PLOS Biology by Ariana S. Huffmyer of the University of Washington, US, and colleagues.

Completely artificial proteins that produce bioluminescence can serve as a non-invasive method for bioimaging, diagnostics, drug discovery, and more.

MBARI researchers have discovered a remarkable new species of sea slug that lives in the deep sea. Nicknamed the "mystery mollusc," the nudibranch Bathydevius caudactylus swims through the ocean’s midnight zone with a large gelatinous hood and paddle-like tail, and lights up with brilliant bioluminescence. Thanks to MBARI's advanced underwater technology, researchers were able to prepare a comprehensive description of the natural history of this amazing animal.
