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 ...

Iron–sulphur (Fe–S) clusters are indispensable participants in three processes that are central to life on earth — respiration, photosynthesis and nitrogen fixation. These ancient modular cofactors ...

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 ...

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 ...

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 ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. New research from the ...
