Science of Botox 1: Clostridium (Above)
The first in series of four videos describing the science of Botox to the layperson. This video focuses on the organism that causes botulism, Clostridium botulinum.

I have some vague recollection of first learning about chemical bonds and hydrophobicity and hydrophilicity of molecules sometime in high school. Important chemistry concepts indeed. My curiosity about mascara (which is one of two MUST HAVES for me in the make-up department, the other is more crucial: under eye concealer) and especially my new affection for L’Oreal’s Beauty Tubes Extend Lash provoked me to make a demonstration video about three different types of mascara: water soluble, water proof and the new Beauty Tubes. It’s sort of long, but it is a real time demo/discussion. I wish I could say I was a polymer chemist, but I’m not…I know just enough to be dangerous! (The video is a bit low quality but since making the video, I learned a lot about video processing, which I did not really know at the time I made this video.)

During my time as a laboratory teaching specialist with the Department of Bioengineering at the University of Illinois, I taught cell biology and tissue engineering. An important aspect of that field is knowing the capabilities of stem cells and their uses in regenerative medicine. Since the field is not always clear to the lay public and because it is a topic full of controversy, I accepted an invitation from Parkland College’s World of Science lectures to speak with the public about what stem cells are, the history of the science of stem cells and some of the major scientific findings.
Once upon a time, youtube did not allow you to upload very long videos, so my hour long talk became 11 separate videos.
