Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. [6] Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3. It has the same crystal structure as corundum ...
A controversial paper [10] [11] published in March 2017 reported evidence for early life in these rocks. The paper describes putative fossilized microorganisms. The structures seen are interpreted as hematite tubes, and filaments, similar in morphology and size to those produced today by bacteria living in subsea hydrothermal vents. Several ...
Rock magnetism is the study of the magnetic properties of rocks, sediments and soils. The field arose out of the need in paleomagnetism to understand how rocks record the Earth's magnetic field. This remanence is carried by minerals, particularly certain strongly magnetic minerals like magnetite (the main source of magnetism in lodestone ).
A common form is held by the mineral hematite, another iron oxide. Hematite forms through chemical oxidation reactions of other minerals in the rock including magnetite. Red beds, clastic sedimentary rocks (such as sandstones) are red because of hematite that formed during sedimentary diagenesis. The CRM signatures in red beds can be quite ...
[19] [20] [21] While this has been shown to work, archaeologists have yet to discover an actual spoon made of magnetite in a Han tomb. [ 22 ] Based on his discovery of an Olmec artifact (a shaped and grooved magnetic bar) in North America, astronomer John Carlson suggests that lodestone may have been used by the Olmec more than a thousand years ...

A quick search of berberine on TikTok reveals countless videos discussing the supplement’s weight loss potential — with some going as far as to claim berberine to be “nature’s Ozempic.”
