Iron: A biological element?
Think of an object made of iron: An I-beam, a car frame, a nail. Now imagine that half of the iron in that object owes its existence to bacteria living two and a half billion years ago. That's the upshot of a study published this week in the Proceedings of the National Academy of Sciences (PNAS). The findings have meaning for fields as diverse as mining and the search for life in space. (2015-06-25)

Linking superconductivity and structure
Superconductivity is a rare physical state in which matter is able to conduct electricity -- maintain a flow of electrons -- without any resistance. It can only be found in certain materials, and even then it can only be achieved under controlled conditions of low temperatures and high pressures. New research hones in on the structural changes underlying superconductivity in iron arsenide compounds -- those containing iron and arsenic. (2015-05-27)

A research team focused on the high-pressure chemistry of a carbonate mineral called siderite, FeCO3, commonly found in hydrothermal vents. Their findings help resolve questions about the presence of iron-containing lower mantle carbonates. (2015-05-15)

Iron-oxidizing bacteria found along Mid-Atlantic Ridge
Bacteria that live on iron were found for the first time at three well-known vent sites along the Mid-Atlantic Ridge. These bacteria likely play an important role in deep-ocean iron cycling, and are dominant members of communities near and adjacent to sulfur-rich hydrothermal vents prevalent along the Mid-Atlantic Ridge. This group of iron-oxidizing bacteria, Zetaproteobacteria, appears to be restricted to environments where iron is plentiful, suggesting they are highly evolved to utilize iron for energy.
