Methanogenic #Archaea as Catalysts for Magnetite Formation in Iron-Rich Marine Sediments https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023JB028312

"The team suspects that these microbes can reduce iron for energy, which triggers the formation of magnetite."

"This study provides insights into the mechanistic links between inflammation and oxidative stress to pollutant particle-induced AD pathologies, with #magnetite apparently inducing the most pathological effects. No exacerbation of the effects was observed in the AD-predisposed model when compared to the wild-type, indicating a particle-induced #neurodegeneration that is independent of disease state."

#Sustainability tip: if you have a (stainless) #steel or #iron object with #rust (brown, Fe2O3) on it, you can lengthen its lifespan by boiling it in regular #water. This will slowly turn the rust into black iron #oxide (Fe3O4), also known as #magnetite. Fe3O4 does not expand and flake like rust, so this slows down the decay of your tool. This is one of the processes known as #bluing.

I tried this with a few rusty household objects and it really worked!

My favorite rock is #BandedIronFormation, a sedimentary rock comprised of thin bands of #Magnetite and #Hematite interlaced with (usually) reddish #jasper (chert #quartz). It's beautiful, primarily down to #TeamQuartz. Sadly, neither hematite or magnetite are in #MinCup23 Vote for quartz here: https://www.mineralcup.org/2023/campaigns/round-1-match-2

@MineralCup I feel personally assaulted that #tourmaline, #beryl, #barite, and even #spodumene and #selenite the largest crystals in the world, aren't in this bracket. These are badass minerals.
I don't think #mercury is even a #mineral. It's just an #element.
And no #hematite or #magnetite? People are just showing off. #bischofite? Girl, please. #shitpostingwithlove

Hooray! @MineralCup is here on Mastodon!

Starting September 1, amazing minerals will go head-to-head in an epic competition to determine which one will join #olivine #garnet #IceMineral #Magnetite #quetzalcoatlite and #fluorite as a #MineralCup champion!

Voting takes place on the Mineral Cup website, but campaigning takes place everywhere, including here. Follow the hashtag #MinCup23 for toots about what makes minerals marvelous.
