🟥 ⛏️ Fluorite crystals inspired the word fluorescence because they glow vividly under ultraviolet light, yet this calcium fluoride mineral forms deep underground. 🎞 @mooneyfinemineral 🔁 ❤️ - Greatly Appreciated Fluorine-rich hydrothermal fluids cool and precipitate with calcium in veins. It commonly lines hydrothermal deposits alongside galena and sphalerite. It is found in a variety of colors, from deep purple and lilac to golden yellow, green, blue, pink, and even colorless, brown, red, or black due to impurity ions and irradiation. Recognize by its perfect octahedral cleavage that splits easily in four directions. Active since Paleozoic times in districts such as the Mississippi Valley. It unveils ancient fluid pathways through the crust and yields fluorine vital for metallurgy and optics. #Fluorite mindat.org

“Magic mushrooms” make psilocybin. Tropical plants make the ingredients of the psychoactive ayahuasca. And toads secrete the mind-altering bufotenin. Now, the tobacco plant makes them all. Thanks to some genetic tinkering, researchers have engineered a close relative of the crop traditionally known for its use in cigarettes to manufacture a wide variety of psychedelics.

The Wollemi pine was known only from 90-million-year-old fossils. Scientists assumed it had gone extinct around the time of the dinosaurs. In 1994, a park ranger in a remote canyon in Australia found a grove of 100 living trees. They are now being cultivated and distributed worldwide. A species that survived two mass extinctions is being planted in backyards. Some things refuse to disappear. #nature #forests #conservation
