#10 - Jeff Smith, PhD: These Machines Will Be In Every Home In The Future!
<p>Dr. Jeff Smith is an analytical Chemistry, a Mass spectrometry expert, and an associate professor in the Chemistry department at Carleton University. He received his BSc in Biochemistry and PhD in Chemistry from York university. He has been the director of the Carleton Mass Spectrometry Center (CMSC) at Carleton since 2015. Additionally, Dr. Smith is currently the Associate Director of the Ottawa Carleton Chemistry Institute since 2016. His work spans many collaborations with companies and government contracts and has a keen insight on the development and limitations of mass spectrometry. </p> <p><br></p> <p>In this episode, Dr. Smith and I discuss what mass specs are, how they are used, and why they are such a crucial tool in every sector you can think of, from healthcare, to home appliances. Having one of these tools implemented in homes can tell you when your food will spoil ahead of time, when you might have a mold problem before you even find out, testing small traces of biomolecules that can detect diseases before they become serious, and many more applications. </p> <p><br></p> <p>Time Stamps:</p> <p> </p> <p>00:00 - Intro</p> <p>01:31 - Disaster that delayed this episode </p> <p>04:06 - Education & Insights on Grad Studies</p> <p>15:38 - Mass Spec facility setup & Projects</p> <p>28:21 - What are mass spectrometers</p> <p>41:06 - Orbitraps</p> <p>43:11 - Iontraps</p> <p>45:08 - Carleton magic show </p> <p>48:37 - Airport chemical testers</p> <p>54:48 - Turbine pump catastrophe </p> <p>01:01:6 - Applications in homes, hospitals, & backpack mass specs </p> <p> </p> <p><br></p> <p><br></p> <p><br></p> <p><br></p> <p><br></p>

#9 - Mahmoud El Saadi: Cold Resistance & Immunity In Fruit Flies
<p>Mahmoud Is a PhD candidate at Carleton University in the biology department, working in Dr. Heath MacMillian's lab. </p> <p><br></p> <p>His work involves studying fruit flies (Drosophila melanogaster) under cold stress by freezing them for periods of time in ethylene glycol, then observing physiological changes after they warm back to room temperature. Mahmoud hopes his research will help identify what makes certain insects resistant to cold, which can have broad applications for pollinators (like bees) in mitigating predation and beginning pollination earlier in the season. We also discuss cold tolerance in fruit flies as it relates to their immune response. </p> <p><br></p> <p>Did you know that fruit flies also have an immune system? Unlike ours it does do not possess antibodies nor does it remember prior infections like our immunity does. Rather, they use peptide chains (a series of amino acids) that can detect and defend against invading bacteria, fungi, and other types of pathogens!</p> <p><br></p> <p>Check out my <a href="https://whereknowledgestemsfrom.com/" target="_blank" rel="noopener noreferer">website</a> for more information about the podcast.</p> <p><br></p> <p>You can also watch this episode on my <a href="https://www.youtube.com/@wkSTEMsf" target="_blank" rel="noopener noreferer">YouTube</a> channel.</p> <p><br></p> <p>Time Stamps:</p> <p><br></p> <p>00:00 - Intro</p> <p>01:41 - Background </p> <p>03:38 - Preserving Insects</p> <p>07:36 - Graduate Research </p> <p>16:15 - Fruit Fly Cold Tolerance</p> <p>28:56 - Fruit Fly Physiology</p> <p>32:46 - Why Flies Rub Their Hands</p> <p>33:40 - Applications of Understanding Cold Tolerance</p> <p>47:34 - Fruit Fly Immunity</p> <p>1:09:39 - Why Use Fruit Flies</p> <p>1:12:16 - CRISPR Fruit Flies</p> <p>1:16:02 - Closing Remarks</p>

#8 - Eugene Fletcher, PhD: Yeast Makes Your Beer & Breaks Down Your Plastic Too
<p>Beer is an internationally loved drink, consumed by millions of people world wide. From different flavours to different types, Dr. Eugene Fletcher, an Assistant professor at Carleton University studies the function of yeast in both brewing your favourite beverage and breaking down plastics. </p> <p>In this Episode, we discuss the process of fermentation, how beer is made, the difference between lager and ale, what steps are taken to infuse beer with different flavours, how yeast is engineered to break down plastic, and future direction for Dr. Fletchers research path. </p> <p>This was fun episode to make as I learned more about beer than i ever knew before, and I hope you do too!</p> <p><br></p> <p>Stream on <a href="https://podcasts.apple.com/us/podcast/where-knowledge-stems-from/id1715136670">Apple Podcasts</a></p> <p>Check out my <a href="https://whereknowledgestemsfrom.com/" target="_blank" rel="noopener noreferer">Website</a> </p> <p>Visit my <a href="https://www.youtube.com/@wkSTEMsf" target="_blank" rel="noopener noreferer">YouTube</a> Page</p> <p><br></p> <p>For more information about Dr. Eugene Fletcher, you can visit his official <a href="https://carleton.ca/biology/people/eugene-fletcher/" target="_blank" rel="noopener noreferer">Carleton</a> profile page, or his <a href="https://www.linkedin.com/in/eugene-fletcher-phd-20740225?originalSubdomain=ca" target="_blank" rel="noopener noreferer">LinkedIn</a> profile.
