Reduced Efficiency of Magnetotaxis in Magnetotactic Coccoid Bacteria in Higher than Geomagnetic Fields [PDF]
Biophysical Journal, 2009 Magnetotactic bacteria are microorganisms that orient and migrate along magnetic field lines. The classical model of polar magnetotaxis predicts that the field-parallel migration velocity of magnetotactic bacteria increases monotonically with the strength of an applied magnetic field.

Gigantism in unique biogenic magnetite at the Paleocene-Eocene Thermal Maximum [PDF]
, 2008 We report the discovery of exceptionally large biogenic magnetite crystals in clay-rich sediments spanning the Paleocene-Eocene Thermal Maximum (PETM) in a borehole at Ancora, New Jersey. Aside from previously-described abundant bacterial magnetofossils,

Microbes as Teachers: Rethinking Knowledge in the Anthropocene
Microbial Biotechnology, Volume 18, Issue 7, July 2025.This essay positions microbes as active ‘teachers’ of ecological wisdom. Microbes demonstrate resilience, symbiosis and ecosystem intelligence through their metabolic networks, providing a dialogic learning experience. Emerging technologies enable reciprocal engagement with microbes, repositioning humans from observers to embedded learners of the vital

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract Low‐temperature hydrothermal fluids in crustal rocks of the Clarion‐Clipperton‐Zone (East Pacific) supply dissolved oxygen into the sediment from below. Diffusive upward transport led to formation of an inverse oxygen gradient zone in the overlying sediments.
