Scoliosis linked to essential mineral

Nobody knows why some children's backs start to curve to one side just as they hit puberty. Most children diagnosed with scoliosis, or curvature of the spine, have no known risk factors.

Deer antlers inspire a new theory on osteoporosis

The loss of manganese could mean that calcium does not stick to bones and could cause osteoporosis. This is the new theory put forward by researchers at the University of Castilla-La Mancha (UCLM) in Spain after studying ...

Increased clumsiness in former welders

Welders who are exposed to manganese from welding fumes, risk developing increased clumsiness – and the result may remain decades after exposure has ceased. This is the finding of a study at the University of Gothenburg, ...

Manganese

Manganese ( /ˈmæŋɡəniːz/ mang-gə-neez) is a chemical element, designated by the symbol Mn. It has the atomic number 25. It is found as a free element in nature (often in combination with iron), and in many minerals. As a free element, manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.

Manganese phosphating is used as a treatment for rust and corrosion prevention on steel. Depending on their oxidation state, manganese ions have various colors and are used industrially as pigments. The permanganates of alkali and alkaline earth metals are powerful oxidizers. Manganese dioxide is used as the cathode (electron acceptor) material in standard and alkaline disposable dry cells and batteries.

Manganese(II) ions function as cofactors for a number of enzymes in higher organisms, where they are essential in detoxification of superoxide free radicals. The element is a required trace mineral for all known living organisms. In larger amounts, and apparently with far greater activity by inhalation, manganese can cause a poisoning syndrome in mammals, with neurological damage which is sometimes irreversible.
