Using Biology to Harness the Power of Fluorine Chemistry

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.

Can adding calcium help forests?

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."

Prettier than dyed eggs?

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).
