The original sunscreen: Particles in ancient seawater helped cyanobacteria to oxygenate Earth’s oceans billions of years ago. The oxygenation of Earth’s atmosphere was thanks, in part, to iron and silica particles in ancient seawater, according to a new study by geomicrobiologists. But these results solve only part of this ancient mystery.
@Patrick, do you know much about pseudocrystals?
A tiny bit. Familar with Penrose tiling, and fiber optics (which are pseudocrystal glass fibers. How does puesdocrystals relate to this paper of early earth?
Well, in my stream of consciousness, early earth had me thinking about abiogenesis, and then thinking about on of my crazy ideas there which involves pseudocyrstals. Which now reminds me that pseudocyrstals are really interesting. We should do some posts to explain what they are, how they form, and what they tell us. Maybe then I might be tempted to share my crazy abiogenesis idea.
Not that crazy:
