What comes to mind when you think of fluorine? The sodium fluoride in toothpaste and mouthwash is the typical, everyday example that most people think of, but fluorine plays a large role in many other compounds. Pure fluorine is a highly reactive and poisonous gas, while fluorinated compounds are incredibly stable, fairly nontoxic, and used in many real-life applications.
This study further supports a connection between acid deposition and forest decline. The authors state, “Continued vigilance in the control of acid rain precursors will be needed to correct these problems, and aggressive options to reduce pollution in rapidly industrializing regions of Latin America, Asia, and Africa are warranted.”

The cocoons, the silkworm itself, and the produced silk become colored when dye is incorporated into the silkworm feed. The concentration of dye in the produced silk changes based on how hydrophobic the dye is (increasing partition coefficient).
I hope most of us have experienced the wonder of watching fireflies lighting up on a warm summer evening.
This article demonstrates the metabolic labeling of bacteria without genetic engineering.

To do the biological study of how particular (good) chemicals like antioxidants affect people, there needs to be a quick, reliable, and consistent way to measure those chemicals in humans. Furthermore, a good method would test for multiple chemicals, because the health benefits from some chemicals only exist in the presence of others (phenolic acids and flavonoids in this case). The authors of this paper demonstrate a gas-chromatography mass-spectrometry (GC-MS) method to investigate how some of the chemicals present in cranberries (from cranberry juice) go into your bloodstream after you ingest them.
