A University of Nebraska-Lincoln research team has identified new microscopic players in the global carbon cycle, a discovery ...

A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate, one ...

NASA’s OSIRIS-REx mission uncovered a cosmic connection between asteroid Bennu and Earth’s Searles Lake. Both contain minerals formed by evaporating salty water, hinting that Bennu’s parent body once ...

CALCIUM carbonate can exist in three polymorphic forms, which in the order of their usual stabilities are calcite, aragonite and vaterite. Calcite is the most stable and the least soluble ...

One of the most common chemicals connected to calcium is called “carbonate”, and together they make calcium carbonate. Calcium carbonate is in eggshells, seashells, a rock called marble, and in ...

A University of Nebraska–Lincoln research team has identified new microscopic players in the global carbon cycle, a discovery that paints a clearer ...

For example, boiling a water sample with 300 milligrams of calcium carbonate in each liter removed as much as 90 percent of the free-floating NMPs. Roughly 25 percent were removed by boiling soft ...
