Page 2: Research news on iron

Iron, as a topic, encompasses its roles and behavior across diverse scientific domains, including its coordination chemistry, redox properties, and biological functions. Central to many metalloproteins, iron cycles between Fe²⁺ and Fe³⁺ states, enabling electron transfer, oxygen transport, and catalysis in systems such as hemoglobin, cytochromes, and iron–sulfur clusters. In materials science, iron’s allotropic transformations, magnetic ordering, and alloy formation underlie the properties of steels and other ferrous materials. In geoscience, iron participates in redox-sensitive mineral formation and biogeochemical cycling, influencing atmospheric composition, nutrient availability, and environmental redox gradients across terrestrial and marine systems.

Wintertime spike in oceanic iron levels detected near Hawaii

Around the world, phytoplankton in the upper ocean help to cycle key nutrients and regulate Earth's climate by absorbing carbon dioxide. These photosynthesizing organisms rely on dissolved iron as an essential micronutrient, ...

Hydrothermal plumes as invisible transport pathways for iron

A new review led by the MARUM—Center for Marine Environmental Sciences at the University of Bremen—highlights how hydrothermal vents on the seafloor shape iron availability and influence the global oceanic element cycles. ...
