Saprolite
Saprolite is a chemically weathered rock. Saprolites form in the lower zones of soil profiles and represent deep weathering of the bedrock surface. In most outcrops, its color comes from ferric compounds. Deeply weathered profiles are widespread on the continental landmasses between latitudes 35°N and 35°S. Conditions for the formation of deeply weathered regolith include a topographically moderate relief flat enough to prevent erosion and to allow leaching of the products of chemical weathering. A second…

Silicene is a two-dimensional allotrope of silicon, with a hexagonal honeycomb structure similar to that of graphene
Contrary to graphene, silicene is not flat, but has a periodically buckled topology; the coupling between layers in silicene is much stronger than in multilayered graphene; and the oxidized form of silicene, 2D silica, has a very different chemical structure from graphene oxide. History Although theorists had speculated about the existence and possible properties of free-standing silicene, researchers…

Leavell, B S. “Thomas Jefferson and smallpox vaccination.” Transactions of the American Clinical and Climatological Association vol. 88 (1977): 119-27 and a few notes
Little Turtle, mentioned in the main article, suffered gout and rheumatism before he died in 1812 Wikipedia says Little Turtle, who also met Washington and Adams, made two trips to Washington, D.C., in 1801–02 and 1809–09 to meet with President Jefferson. Little Turtle died on July 14, 1812, and had suffered from gout and rheumatism for some time. He was honored…

Chrysiasis
Chrysiasis is a dermatological condition induced by the parenteral administration of gold salts, usually for the treatment of rheumatoid arthritis. Such treatment has been superseded as the best practice for treating the disease because of “numerous side effects and monitoring requirements, their limited efficacy, and very slow onset of action”. Similar to silver, a gold preparation used parenterally for a long period may rarely…

Acid phosphatase (systematic name phosphate-monoester phosphohydrolase (acid optimum)) is an enzyme that frees attached phosphoryl groups from other molecules during digestion
Acid phosphatase (EC 3.1.3.2, systematic name phosphate-monoester phosphohydrolase (acid optimum)) is an enzyme that frees attached phosphoryl groups from other molecules during digestion. It can be further classified as a phosphomonoesterase. It is stored in lysosomes and functions when these fuse with endosomes, which are acidified while they function; therefore, it has an acid pH optimum. This enzyme is present in many animal and plant…

Sodium aurothiomalate aka gold sodium thiomalate
Sodium aurothiomalate (INN, known in the United States as gold sodium thiomalate) is a gold compound that is used for its immunosuppressive anti-rheumatic effects. Along with an orally-administered gold salt, auranofin, it is one of only two gold compounds currently employed in modern medicine. Medical uses It is primarily given once or twice weekly by intramuscular injection for moderate-severe rheumatoid arthritis. It has also proven to…

Thrombin
Thrombin (fibrinogenase, thrombase, thrombofort, topical, thrombin-C, tropostasin, activated blood-coagulation factor II, blood-coagulation factor IIa, factor IIa, E thrombin, beta-thrombin, gamma-thrombin) is a serine protease, an enzyme that, in humans, is encoded by the F2 gene. During the clotting process, prothrombin (coagulation factor II) is proteolytically cleaved by the prothrombinase enzyme complex to form thrombin. Thrombin in turn acts as a serine protease that converts soluble fibrinogen into insoluble strands of fibrin, as well as catalyzing many other coagulation-related reactions. History After the description…

Microsomal prostaglandin E synthase-1 (mPGES-1)
Microsomal prostaglandin E synthase-1 (mPGES-1) or Prostaglandin E synthase is an enzyme that in humans is encoded by the PTGES gene. The protein encoded by this gene is a glutathione-dependent prostaglandin E synthase. The expression of this gene has been shown to be induced by proinflammatory cytokine interleukin 1 beta (IL1B). Its expression can also be induced by tumor suppressor protein TP53, and may be involved in…

Albumen prints and egg whites…all the rage back in the day…and a few other things
The albumen print, also called albumen silver print, was published in January 1847 by Louis Désiré Blanquart-Evrard, and was the first commercially exploitable method of producing a photographic print on a paper base from a negative. It used the albumen found in egg whites to bind the photographic chemicals to the paper and became the dominant form of photographic positives from 1855 to the start…

Thunderstones (and Touchstones) in Asian Tradition
In Burma they are used as a cure and preventative for appendicitis. In Japan they cure boils and ulcers. In Malaysia and Sumatra they are used to sharpen the kris, are considered very lucky objects, and have been credited with being touchstones for gold. A touchstone is a small tablet of dark stone such as slate or lydite, used for assaying precious metal alloys. It has a…

Did WHO Study Conclude That Natural Blondes Are Likely To Be Extinct Within 200 Years? – Snopes
https://www.snopes.com/fact-check/gone-blonde/ Evidently these things or things very like them have been published (here and elsewhere) since at least the time of the Civil War. This quote is said to be from an article dated 1890: The girl with the golden tresses is doomed, and within six hundred years blondes will be extinct. The fate of…
