How does soap work?

I’m purposefully choosing to write about topics that aren’t specific to the biology and epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, ie., the virus that causes coronavirus-19) for a few reasons. First, I typically post once or twice a week but things with this virus are changing daily so I won’t be able … Continue reading

#WomeninScience and Cyanobacteria have sunscreen

In light of today being the International Day of Women and Girls in Science, I went searching for research done by a women to profile today. I decided to start close to home and look through the biology department at the University of Alberta (U of A) where I did my undergrad and did not … Continue reading

Mini post: Ice rinks and asthma

When I was diagnosed with asthma as a kid, I remember someone saying that it wouldn’t go away unless I stopped skating because of the air quality in rinks. I was wondering what the research on this is. Rundell (2004) found that the pulmonary function, basically how well a person breaths, of a group of … Continue reading

What are the differences between the blade of a hockey skate and a figure skate?

I grew up figure skating, but I am also very comfortable on a pair of hockey skates. (Please don’t call them women’s vs men’s as this perpetuates stereotypes that just aren’t true.) When I taught learn-to skate lessons I was often asked about the differences between the two types of skates and when this question … Continue reading

Magic Mondays: Surface Tension and Basilisk Venom

A few years ago, I made a potions kit as a gift for a young Harry Potter fan. I had a blast coming up with different science experiments that could be done with ingredients from the grocery store and renaming them to create my own magical illusions. Well someone asked if I could share these … Continue reading

A dose of sugar makes the future seem worth waiting for

I wrote a post last fall on the impact of seeing nature on our ability to pass on small rewards now in order to receive bigger rewards in the future. To be honest, I had since forgotten about this but having been in a pretty good deep freeze off and on (but mostly on) for … Continue reading
