In chemistry, a molecule or ion is said to be chiral if it cannot be superposed on to its mirror image by any combination of rotations, translations, or conformational changes. A chiral molecule or ion exists in two forms, called enantiomers, that are mirror images of each other; they are often distinguished as either ‘right-handed’ or ‘left-handed’ by their absolute configuration. Enantiomers exhibit similar physical and chemical properties, except when interacting with polarized light and reacting with other chiral compounds, respectively.

One of humankind’s most precious fertilizers is slipping away. Phosphorus, which today comes mostly from nonrenewable reserves of phosphate rock, typically winds up in municipal waste streams. In the best cases, wastewater treatment plants sequester about 90% of that phosphorus in “sludge” and decompose that sludge into something known as digestate.

Carbon compounds form the foundations of all known life, and as such are of a particular interest to scientists working to understand both how life developed on Earth, and how it could potentially develop elsewhere in our universe. As such, the study of interstellar organic (carbon-containing) chemistry is an area of keen fascination to many astronomers. An international team of astronomers has used NASA’s James Webb Space Telescope to detect a carbon compound known as methyl cation for the first time. This molecule is important because it aids the formation of more complex carbon-based molecules. It was found in a young star system with a protoplanetary disk, 1,350 light-years away in the Orion Nebula.
