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...
I observe a red to blue color change when I rinse my bowl after eating frozen blueberries. Sounds like an acid-base reaction, doesn’t it? Well, read on to learn about the blueberry surprise!
Millions of years of evolution has endowed brown (Ursus arctos) and black (Ursus americanus) bears with the enviable metabolic capacity to starve themselves for a long period of time and still survive. Truly, bears are chemist extraordinaires and their hibernation chemistry overall is arguably without equal in the mammalian world. Let's take an introductory look at what's going on.

Hello, and welcome back to my second blog about chemistry education in the tri-border region of California, Arizona, and Mexico. In my last article I described the area and students who attend the two institutions in Yuma, AZ- Arizona Western College (AWC) and Northern Arizona University-Yuma (NAU). In this second post I will talk briefly about my experiences teaching an upper-division biochemistry course. I presume that what I observe in my classes is not much different than what you observe in your classes.
The June, 2018 issue of the Journal of Chemical Education contains an article that describes a simple, yet fascinating experiment that you and your students are going to love! It involves the use of butterfly wings from the genus Morpho. I obtained some of these wings and enjoyed experimenting with them. You will too!

If you want to lose weight, you have to burn calories. Anyone who has gone on a diet knows this. But when someone loses weight, have you ever wondered where the lost mass goes?
