Bacterial Cell Biology: Managing Magnetosomes [PDF]
Current Biology, 2006 Sensing of magnetic fields by living organisms -- magnetosensing -- is best understood in magnetotactic bacteria. Recently work has provided new insight into the biogenesis of bacterial magnetosomes, and links these organelles to a newly recognized prokaryotic cytoskeletal filament which organizes magnetosomes into a sensory structure capable of ...

Magnetic Study of Co-Doped Magnetosome Chains [PDF]
The Journal of Physical Chemistry C, 2018 Magnetotactic bacteria synthesize a chain of magnetic nanoparticles, called magnetosome chain, used to align and swim along the geomagnetic field lines. In particular, Magnetospirillum gryphiswaldense biomineralize magnetite, Fe3O4. Growing this species in a Co-supplemented medium, Co-doped magnetite is obtained, tailoring in this way the magnetic ...

Discovery Prospects for a Supernova Signature of Biogenic Origin
, 2011 Approximately 2.8 Myr before the present our planet was subjected to the debris of a supernova explosion. The terrestrial proxy for this event was the discovery of live atoms of 60Fe in a deep-sea ferromanganese crust.
