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 …

The 4.5-Ga-old Martian meteorite ALH84001 houses 3.9-4.1-Ga-old magnetite nanocrystals,
the likes of which in terrestrial environments are secreted by magnetotactic bacteria, that …

Magnetotactic bacteria display one of the clearest behavioral responses to the geomagnetic
field of any living organism, and are one of the few known prokaryotes which have the ability …

Dissimilatory iron-reducing bacteria are able to enzymatically reduce ferric iron and couple
to the oxidation of organic carbon. This mechanism induces the mineralization of fine …

Abyssal manganese nodules have been explored widely for their economic potential and
paleoenvironmental significance. Debate about whether biogenic or physical‐chemical …

Paleomagnetie dating of Quaternary sediments is a secondary dating method that is based
on matching polarity transitions, excursions and secular variations of the paleomagnetic field …

Single‐domain magnetite particles produced by magnetotactic bacteria (MTB) and aligned
in chains, called magnetosomes, are potentially important recorders of paleomagnetic …

Living magnetotactic bacteria from freshwater environments show, under natural and
laboratory conditions, a great variety of morphological appearances. Their magnetosomes …

Magnetotactic bacteria (MTB) are ubiquitous in the aquatic environment and have been
identified from almost every continent; however, there are only a few reports of MTB from …

Magnetite is the magnetic mineral most prominent as a remanence carrier in sediments. Not
surprisingly, the discovery of a magnetic bacterium (Blakemore, 1975) caught the attention …
