From as far back as 1787, scientists had hypothesized the existence of an unknown base metal in alum. While not quite the man who discovered aluminum, British chemist and inventor Sir Humphry Davy, can be credited for naming it (first as "alumium" before being given its current designation) in 1808. It was in 1825 when a Danish chemist and ...

Dec 08, 2020· Exoplanet discovery. In a press release on February 22, 2017, NASA announced the discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds–all of them with the potential for water on their surface–is an exciting discovery in the search for life on other worlds.
A pyrophyllite-rich alteration zone (20-100 m thick) is widely developed in pre-3.43 Ga submarine basalts that occur underneath the oldest known (3.43 Ga) stromatolite-rich beds (Strelley Pool Chert, Allwood et al., 2006) and the oldest known (ca. 3.43 Ga) land surface (Buick et al., 1995) in the North Pole Dome area of the Pilbara Craton, Western Australia.

This era declined after the 1970s owing to the difficulty of cultivating fastidious bacterial species under laboratory conditions. Various strategies, such as rational drug design, to date have not led to the discovery of new antimicrobial agents. However, new promising approaches, e.g. genome mining or CRISPR-Cas9, are now being developed.

Feb 12, 2016· „The most common iron oxide is hematite, Fe2O3, which is the end product of many geological processes and the main source of iron for our civilization," explains Bykova. During the past five years, however, scientists have discovered other iron oxides like Fe4O5, Fe5O6, and Fe13O19 that form at high pressures and temperatures.
