Did marine life in the palaeocene use a #compass?
Based on a sophisticated method, an international team has succeeded in mapping #magnetic domains in giant fossilised magnetic #microparticles: these may have served as compasses for ancient organisms

.@KaylaStoy & @wc_ratcliff explore a #PLOSBiology study which shows that #multicellular #magnetotactic #bacteria form obligately multicellular consortia of genetically diverse cells with rudimentary division of labor Paper: https://plos.io/460zcGC Primer: https://plos.io/3LnqVD1

#Multicellular #magnetotactic #bacteria (MMB) have no unicellular stage. @SchaibleGeorge @environmicrobio &co's study of MMB consortia shows that individual cells are not genetically identical & have significant metabolic differentiation #PLOSBiology https://plos.io/460zcGC

Bioremediation of contaminated waterways, particularly those flush with heavy metals and radioactive materials, is an expensive and time-consuming process.

One potential avenue is the use of magnetotactic bacteria that can accumulate such materials and be themselves removed via magnets.

Now, scientists have analyzed and shown the ability of M. magneticum to bind uranium via their cell walls.
