ImageThe Wieliczka Salt Mine (Polish: Kopalnia soli Wieliczka), located in the town of Wieliczka in southern Poland, lies within the Krakówmetropolitan area. The mine, built in the 13th century, produced table salt continuously until 2007, as one of the world’s oldest salt mines still in operation. From its beginning and throughout its existence, the Royal mine was run by the Żupy krakowskie Salt Mines. Commercial mining was discontinued in 1996 due to low salt prices and mine flooding.

The mine’s attractions include dozens of statues, three chapels and an entire cathedral that has been carved out of the rock salt by the miners. The oldest sculptures are augmented by the new carvings by contemporary artists. About 1.2 million people visit the Wieliczka Salt Mine annually and you can visit it virtually HERE

Thiotimoline is a fictitious chemical compound conceived by science fiction author Isaac Asimov and first described in a spoof scientific paper titled “The Endochronic Properties of Resublimated Thiotimoline” in 1948. Asimov went on to write three additional short stories, each describing different properties or uses of thiotimoline.

In Asimov’s writing, thiotimoline is notable for the fact that when it is mixed with water, the chemical actually begins to dissolve before it contacts the water. This is explained by the fact that in the thiotimoline molecule, there is at least one carbon atom such that, while two of the carbon’s fourchemical bonds lie in normal space and time, one of the bonds projects into the future and another into the past. Thiotimoline is derived from the bark of the (fictitious) shrub Rosacea karlsbadensis rufo, and the thiotimoline molecule includes at least fourteen hydroxy groups, two aminogroups, and one sulfonic acid group, and possibly one nitro compound group as well. The nature of the hydrocarbon nucleus is unknown, although it seems in part to be an aromatic hydrocarbon.

Flavr Savr (also known as CGN-89564-2) (pronounced “flavor saver”), a genetically modified tomato, was the first commercially grown genetically engineered food to be granted a license for human consumption. It was produced by the Californian company Calgene, and submitted to the U.S. Food and Drug Administration (FDA) in 1992. On May 18, 1994, the FDA completed its evaluation of the Flavr Savr tomato and the use of APH(3′)II, concluding that the tomato “is as safe as tomatoes bred by conventional means” and “that the use of aminoglycoside 3′-phosphotransferase II is safe for use as a processing aid in the development of new varieties of tomato, rapeseed oil, and cotton intended for food use.” It was first sold in 1994, and was only available for a few years before production ceased in 1997. Calgene made history, but mounting costs prevented the company from becoming profitable, and it was eventually acquired by Monsanto Company…..
