Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO3)2.

A substance is anhydrous if it contains no water, for example, salts lacking their water of crystallisation.

Facilities exist to refine hydrous ethanol feedstock into anhydrous ethanol (0 water content), but the process appears to be uneconomic at this time and the facility remains idle.

In an attempt to reduce the rates of mother to child transmission of HIV AIDS, an infantile lactose formula was supplied to the mothers of HIV AIDS infected babies.

It is seen in ice at high pressure (Ice X), and also in the solid phase of many anhydrous acids such as hydrofluoric acid and formic acid at high pressure.

Fat free mass (muscle) is a good conductor as it contains a large amount of water (approximately 73 ) and electrolytes, while fat is anhydrous and a poor conductor of electric current.

Far from providing immunity against evolutionary pressures, culture often creates new ones. For example, the genes associated with digestion of lactose are more prevalent in populations that have traditionally bred cattle and consumed milk.

These include Rosolic acid to inhibit bacterial growth in general, except for faecal coliforms, Bile salts inhibit non enteric bacteria and Aniline blue indicates the ability of faecal coliforms to ferment lactose to acid that causes a pH change in the medium.

Furthermore, the inclusion of milk as a group unto itself implies that is an essential part of a healthy diet, despite the many people who are lactose intolerant or choose to abstain from dairy, and a number of cultures that have historically consumed little if any dairy products.
