Magnetism as a Proxy for Sedimentary REY Enrichment in the Eastern Pacific Ocean and Its Potential Use for Identifying Deep Ocean REY

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Rare earth elements and yttrium (REY) are critical for advanced technological and environmental applications. REY‐enriched deep‐sea sediments have attracted attention as significant potential REY resources. However, efficient identification of these deposits in the open oceans is a persistent challenge.

Magnetosomes Are Cell Membrane Invaginations Organized by the Actin-Like Protein MamK [PDF]

, 2006
Magnetosomes are membranous bacterial organelles sharing many features of eukaryotic organelles. Using electron cryotomography, we found that magnetosomes are invaginations of the cell membrane flanked by a network of cytoskeletal filaments.
