What does it mean to be a carrier?

One of the things that my biology students often struggle with is what exactly does it mean to be a carrier for a particular trait. This is a difficult concept because it seems odd that we might have the information in our DNA for a trait such as a disease but we don’t actually have … Continue reading

Would a park in your neighbourhood make you bike more or less?

In my Master’s research, I examined the impact of urban greenspaces on decisions to move into the suburbs. It had a significant effect being one of the top three reasons why individuals chose to live on the outskirts of Edmonton. I, on the other hand, prefer to live closer to the centre of Edmonton, but … Continue reading

Bike lanes: Separated or not?

I haven’t been able to ride my bike outside since my crash over two years ago, but I miss it. What I don’t miss is the feeling that I can’t trust the drivers on the road next to me. But here’s the thing, I was on a separated path when my crash happened because a … Continue reading

Asthma, neurons, and the immune system

I still remember my first asthma attack. It’s a pretty terrifying feeling and one that I have worked hard against. The more I improve my cardiovascular system, the harder I’m able to push without feeling asthma’s grasp. But I’m lucky. I am able to train and improve but asthma can be debilitating. And while we … Continue reading

Pigeons are better at multitasking

I feel like these days people claim their ability to multitask as a badge of honour. Eventually, it will degrade to a playground quality fight: “Yeah, well I have ten different windows open on my computer and I’m simultaneously leading a meeting while attending a webinar that is vital to my field.” When I am … Continue reading

Does the cyclist or the equipment matter more?

There are many ways that a person can modify a bike to give themselves an advantage and with two major cycling events (Tour of Alberta – road cycling and FISE world action sports festival – a couple different BMX events and mountain bike slope style) in Edmonton in September these modifications have been on my … Continue reading

Which way does a tree lean?

If conditions are ideal a tree grows straight up. However, scarce resources may cause trees to grow with a lean, and it turns out that the direction and amount of this lean is affected by where a tree is in the world. Johns et al (2017) focused on a specific tree, Cook Pine, and found … Continue reading

The summer slide

With the start of the school year on the way many teachers are preparing themselves to address the summer slide, the learning loss that students experience over the summer. While a little loss may be expected some groups of children are affected more than others. Blazer and the Miami-Dade County school system conducted research that … Continue reading

Do Darwin’s finches actually have different DNA?

I have an undergraduate degree in biology, which means I have studied Darwin’s finches more times than I can count. The short version is that Darwin was on a ship that sailed to the Galapagos Islands. While there he observed many different species and variation within and between species. One of the groups that interested … Continue reading

Performance enhancing bacteria?

While it seems wrong to not write about the eclipse after yesterday’s event, I really can’t add anything that isn’t already out there so instead I’m going for something completely different. With several members of the Canadian track and field team being impacted by norovirus at the recent 2017 World Championships in Track and Field, … Continue reading
