#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: Which direction is that track?

Have you ever looked at the tracks of a snowshoe hare and wondered which way it was travelling? My experience is that most people think that the hare that left the tracks in the photo was travelling south. The two prints that are next to each other at the top of the photo are the … Continue reading

Mini post: Horns vs Antlers

Someone asked me the difference between horns and antlers so I thought I’d make it a mini post. Horns, like those of the big horn sheep, have a bony core that grows from the skull and an outer layer of keratin which is the substance that makes your hair and nails. Horns are permanent and … Continue reading

Mini post: Winter survival strategies

Humans have the ability to bundle up when the weather gets cold, but how do different animals get through the cold and snow? There are many different strategies for winter survival, and most animals will do more than one. Here are three different animals and their strategies for dealing with winter. Snowy owls migrate in … 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

An amazing tongue

I went for a walk in Edmonton’s river valley today, at least walking was my plan, but I was quickly sidetracked by wildlife. Within minutes of arriving in the park a pack of coyotes ran in front of me. Sadly, they were a little too far and to quick for the cameras I had available. … Continue reading

Magic Mondays: Oobleck

I wrote a post a while ago that you can read about non-Newtonian fluids so I’m just going to give you the potion recipe here. I’m not sure if I’m going to continue magic Mondays on a weekly basis. It might become a monthly thing instead. But you can still download the potions book and … Continue reading

Pets and poinsettias

I was all prepped to update this post, but it turns out nothing has really changed. People still think that poinsettias are poisonous and sources that are seen as authorities in social media continue to propulgate the myth. But poinsettias are not poisonous. I added one additional reference at the start and left the original … Continue reading

Electrons want to be couch potatoes too

The electrons, negatively charged particles, in an atom “want” to be at their ground state: the lowest level of energy possible for them, kind of like you hanging out on your couch reading blog posts. However, like you, the electrons can get more energy, or be excited, by things they eat. . Okay, so I … Continue reading
