Hot Topic for Early Spring: Thermogenesis of Eastern Skunk Cabbage
Dean Campbell | Sat, 03/06/2021 - 22:07
The blossoms of eastern skunk cabbage produce heat for a couple of weeks in early spring. This heat, which can be detected using an infrared camera, results from oxidation of carbohydrates. The mechanisms behind this process can be used to introduce energy transduction during classroom discussions of thermochemistry.
Chemistry of Brewing Part I: The Malt
Jerry Godbout | Sun, 07/05/2020 - 20:10
The process of making beverages from fermented grain is a chemical synthesis slightly newer than human civilization itself. This article descibes the chemistry of the first step- malting the raw mature grain.

Liquid nitrogen is used to visualize the aerosol particles emitted while speaking, coughing, breathing, and sneezing. The ability of various masks to block these droplets was also tested.
Metabolic Marvels of Bear Hibernation- Part 4
Scott Donnelly | Tue, 05/19/2020 - 20:35
Welcome to Part 4 in a series of posts looking at the metabolic chemistry that allows a bear to opt to survive winter by not eating at all and by doing so increase its chances of dying from starvation. By the end of hibernation up to a third- and more for a pregnant bear- of a bear's pre-denning mass may have been devoured by the bear's metabolic and physiological needs. A remarkable animal. A remarkable study in biochemistry. Enjoy...
