The concept there is that dumping iron into the water would stimulate the growth of phytoplankton, which would pull carbon dioxide out of the air. But scientists have questioned how well it really works, and what sorts of side effects it could have on ocean ecosystems. Environmental group...

A highly weathered soil that is red due to the high content of iron oxide minerals. Courtesy of U.S. Department of Agriculture. The lateral extent of a soil can be difficult to define because adjacent soils can have sharp to gradual transitions. Soil bodies can be conceptualized and mapped...

behind a neutron star or a black hole. The problem with this is that with 26protonsin its atomic nucleus, iron is far from the heaviest element. This is even the case when you don't include non-naturally occurring elements, like 117-protontennessine, which can be created in the lab. ...
Why is iron more reactive than copper? Why does electroplating take place on the cathode and electrorefining take place on the anode? The iron formed in a blast furnace is called pig iron, which contains impurities that make the metal brittle. What are these impurities, and how did they com...
