The very first cells obtained their energy from geochemical reactions. LMU researchers have now managed to recreate this ancient metabolic process in their laboratory. Most likely, the earliest ...
A bacterium that uses sulfide as an energy source to metabolize solid iron oxides has been discovered, revealing a biological reaction that was previously assumed to be solely chemical. This finding ...
In a number of biological processes, iron-sulfur clusters play a vital role, where they act as cofactors to enzymes. Research now shows that cubic clusters can support unusual bonding states. This ...
This is a preview. Log in through your library . Abstract Cultures of the blue-green alga, Aphanocapsa, were grown under iron-limiting conditions and changes in concentration of redox components of ...
THE lecturer commenced by stating the origin of the sulphurous impurity in coal gas to be the iron pyrites which is contained in coal, and that in the manufacture of gas, when the coal is strongly ...
Crushed by the weight of the thousands of kilometers of liquid iron and sulfur, superheated metal and minerals and cool crustal rock above, the Earth’s core is under immense pressure. Heated from ...
University of Vienna researchers discover MISO bacteria that breathe iron minerals while oxidizing toxic hydrogen sulfide in ...

Mars may have a solid inner core just like Earth
Scientists have identified another possible commonality between Earth and Mars: a solid inner core. New research from the ...
Mineralogists have discovered a previously unknown phenomenon in soil samples from the asteroid 'Itokawa': the surface of the celestial body is covered with tiny hair-shaped iron crystals. The team ...
