Recent research from the Herbert Wertheim School of Public Health at the University of California San Diego reveals a disturbing correlation between exposure to widely-used herbicides and declined brain function among adolescents. The study, published in Environmental Health Perspectives, draws attention to the associations of the herbicides glyphosate and 2,4-dichlorophenoxyacetic acid (2,4D) with neurobehavioral performance.

Counterfeit detector pens use a starch-iodine reaction to identify fake bills. But could you fool them with chemistry? In today's episode, we dive into the chemistry of iodine, its color and its clock reactions, all while making a little extra cash on the side. Let's say that we wanted to fool these counterfeit detection pens for science, how could we make this reaction not happen on normal paper?
