Science Talks: Environmental Chemistry: Safeguarding our Indoor Air
Breathing is fundamental to life, and most of us spend the vast majority of our time indoors. But have you ever stopped to consider what’s in the air we breathe inside our homes, workplaces, and schools? Maintaining clean indoor air is essential for protecting our health and well-being. However, indoor air quality is influenced by a mix of pollutants from both indoor activities and outdoor sources. Everyday actions, such as cooking or using certain appliances, can release pollutants into our living spaces. Meanwhile, outdoor air pollution—like wildfire smoke—can seep indoors, compounding the problem.
Join us on January 30 for a webinar with award winning chemist and faculty member Ran Zhao as he introduces key indoor air pollutants, with a spotlight on fine particulate matter, which poses significant health risks. He’ll share insights from two recent research projects and highlight the innovative use of low-cost air quality sensors that make these studies possible and show how science can help us breathe easier.
Date: Thursday, January 30
Time: 12 - 1 p.m. MST
Cost: Free via Zoom

Science Talks: Protecting our oceans: Alien invaders and how to stop them
“Biological invasions” are a global problem created by people intentionally and unwittingly moving flora and fauna into environments where they don’t belong. This talk will explore the causes and consequences of 'biological invasions’, a global problem created by people intentionally and unwittingly moving flora and fauna into environments where they don’t belong. Today, thousands of invasive species threaten biodiversity and disrupt societies globally, and the problem is expected to intensify as our global climate continues to change. In searching for solutions, the talk will highlight innovative ways that communities are dealing with invasive species– from designing robots to creating cookbooks– and defending nature and local livelihoods in the process.
Join faculty member and Canada Research Chair in Aquatic Global Change Ecology and Conservation, Stephanie Green explain what invasive species are, why they are a problem and how they relate to our global and local communities, here in Edmonton, and what can be done to defend against invasive species and conserve threatened ecosystems.
Science Talks: Quantum Materials: From exotic particles to new technologies
To learn about the world at the most fundamental level, particle physicists use enormous machines called particle colliders. These devices cause atoms to collide head-on at very high energies — revealing the ultrasmall elementary particles that make up this matter, such as electrons and quarks. Condensed matter physicists have discovered that when the same matter is probed in table-top experiments at much lower energy and temperatures where quantum effects manifest, matter often behaves as though it is made up of new particles very different from electrons and quarks. In this webinar, Joseph Maciejko explains how theoretical physics can help us identify new kinds of materials hosting “exotic particles.” These very foundational discoveries are what is advancing quantum science and will have vast implications for the technology we use every day — with potential applications in communications, computing and data security.

Science Talks: Cannabis use in the modern era: The highs and lows
The first documented use of cannabis occurred about five thousand years ago when it was used as a treatment for malaria, rheumatic pain and as an analgesic. In the modern era cannabis has been labelled as an illicit drug of abuse due to the actions of its primary psychoactive ingredient, Delta-9-tetrahydrocannabinol (THC). However, several countries have legalized cannabis use for recreational purposes which has created a drive to more fully understand its effects on populations as a whole.
Hear from Declan Ali, dean of the Faculty of Science on a short but intriguing history of cannabis use and abuse and its effects in the modern era as more countries look towards legalization of cannabis as a recreational compound and as an important medicinal agent.
