Switch-in-a-cell electrifies life

Scientists at Rice University have developed synthetic protein switches to control the flow of electrons.

Bioluminescent worm found to have iron superpowers

Researchers at Scripps Institution of Oceanography at the University of California San Diego have made a discovery with potential human health impacts in a parchment tubeworm, the marine invertebrate Chaetopterus sp., that ...

In these microbes, iron works like oxygen

A pair of papers from a UW–Madison geoscience lab shed light on a curious group of bacteria that use iron in much the same way that animals use oxygen: to soak up electrons during biochemical reactions. When organisms—whether ...

Bacteria can use magnetic particles to create 'natural battery'

New research shows bacteria can use tiny magnetic particles to effectively create a 'natural battery.' According to study published in journal Science on 27 March, the bacteria can load electrons onto and discharge electrons ...

Structure of an iron-transport protein revealed

For the first time, the three dimensional structure of the protein that is essential for iron import into cells, has been elucidated. Biochemists of the University of Zurich have paved the way towards a better understanding ...

Iron in primeval seas rusted by bacteria

(Phys.org) —Researchers from the University of Tübingen have been able to show for the first time how microorganisms contributed to the formation of the world's biggest iron ore deposits. The biggest known deposits – ...

Toward a systems biology map of iron metabolism

Scientists at the Wake Forest University School of Medicine, the University of Manchester in the United Kingdom, and the Virginia Bioinformatics Institute at Virginia Tech have taken the first steps toward constructing a ...
