So yesterday I completed a sprint duathlon. Just for fun and on my own because we are still in the midst of social distancing due to the Covid-19 pandemic. In the morning I got up and had some Greek yogurt and fruit and then I went and did a 5 km run, 20 km bike, … Continue reading
When you’re used to clear water coming out of the tap it’s easy to make assumptions about how clean a water body is based on how clear it is. This means that most people assume that the North Saskatchewan River through Edmonton, Alberta, Canada is pretty dirty, particularly in the spring. The visible brown colour … Continue reading
Typically when I sit down to write my blog post each week I go looking for research that I find interesting or for answers to questions that I or others have (if you have questions feel free to send them my way). But, what I have realized is that, as a result, I rarely consider … Continue reading
A friend of mine had a disagreement with some colleagues at a pd session. My friend correctly asserted that when you put ice into a blender for a smoothie, the ice does not undergo a state change, except for some minor melting due to heat from friction. The ice will melt as the smoothie warms … Continue reading
I used to run a nature information line and in the spring we would have any number of people calling with concerns about “abandoned” baby animals. I didn’t mind the phone calls to be honest as it meant the person called before taking action. Generally the advice is the same, look for actual signs of … Continue reading

I’ve been working at home for about two weeks now, since the coronavirus pandemic has triggered the vacating of pretty much every public space around the world. Yesterday I gave in and accepted that this was a long term … Continue reading
I’m not willing to jump on some bandwagons. You won’t find me stockpiling toilet paper. I definitely won’t be buying a mask to wear which probably wouldn’t fit properly, would make me touch my face more, might give me a false sense of security as I rub my eyes after touching a door handle, and … Continue reading
Back when I did outdoor programming, I used to give classes of 20 kindergarteners snowshoes. They would then run en masse across the snow. On occasion, you could see the poor small mammals, who had been happily hanging out beneath the snow, run out ahead of the kids. The kids and their snowshoes were crushing … Continue reading
Our DNA is located in 23 pairs of chromosomes. These chromosomes have genes located at specific locations that contain the recipes for everything made by our bodies. The ends of the chromosomes have telomeres, which are repeating sequences of specific base pairs (the alphabet of our DNA) that don’t code for anything and act like … Continue reading
