Nature's Way To Make the Lantibiotics  Heather A. Relyea and Wilfred A. van der Donk
This article focuses on one class of antimicrobial compounds, the lantibiotics, and discusses their biosynthetic pathways as well as their molecular mode of action. In the course of the review, the meaning of the terms regio-, chemo-, and stereoselectivity are discussed.

An Experiment to Demonstrate How a Catalyst Affects the Rate of a Reaction  Christine L. Copper and Edward Koubek
This experiment, which is a modified version of the traditional iodine clock reaction, allows students to calculate rates of reaction, orders of reactants, and activation energies. It also lets students discover that to increase a reaction's rate, a catalyst need only provide any additional pathway for the reaction, not necessarily a pathway having a lower activation energy.

A Further Demonstration of Sulfite-Induced Redox Cycling of Metal Ions Initiated by Shaking  Horacio D. Moya, Eduardo Almeida Neves, and Nina Coichev
Details of a fascinating laboratory demonstration of the sulfite-induced redox cycling of Ni(II)/Ni(III), which is initiated by shaking the solution in the presence of air, are reported. The balance between the sulfite and oxygen concentration controls the direction of the overall reaction.

Photocatalytic Degradation of a Gaseous Organic Pollutant  Jimmy C. Yu and Linda Y. L. Chan
A simple and effective method to demonstrate the phenomenon of photocatalytic degradation of a gaseous organic pollutant was developed. Titanium dioxide (anatase) was used as the photocatalyst, and sunlight was found to be an effective light source for the activation of TiO2. The organic pollutant degrade in this demonstration was a common indoor air pollutant, dichloromethane.
