Jumping in figure skates

Figure skates are not exactly the easiest things to jump in. They are stiff and restrict the motion of your foot and your ankle. Which makes me wonder how this affects the way the rest of your leg moves while jumping. Haguenauer, Legreneur, and Monteil (2006) examined national and international figure skaters jumps comparing their … Continue reading

Science for communicators and communication for scientists

This is a short post today because I can’t say anything better than Alan Alda can. As a teacher, teacher trainer, and someone who wants everyone to get excited about science, and get moving on climate change and other sustainability challenges, I was intrigued by Alda’s most recent book “If I understood you, would I … Continue reading

Jazz and classical musicians are different

I went to two concerts by the Edmonton Symphony Orchestra this weekend. They both featured the symphony playing jazz music with professional jazz musicians. It was interesting to hear the symphony playing jazz style. No offence to any of the symphony musicians, who are all phenomenal, but it seemed like some of them struggled more … Continue reading

Normalizing obesity

It’s hard not to notice the number of individuals who are overweight these days. So with all the New Year Resolutions you have to wonder if there is an increasing dedication (however temporary) to losing weight. According to a study by Snook et al (2017) probably not. As increasing body weight becomes more and more … Continue reading

Hypertension and stopping research studies early

These two topics aren’t related except that while reading an opinion article published on The JAMA Network about the challenges and opportunities of implementing the most recent guidelines for the diagnosis and treatment of hypertension I learned that some clinical studies are stopped early because the study is showing positive results. Hypertension first. The American … Continue reading

They just did what!?

I’m a long way from needing my hand amputated but I have certainly had some experiences over the past couple years that have made me realize how two handed and opposable thumb dependent out world is. From tying shoelaces to taking paper towels from the dispensers the world is built for two hands that function … Continue reading

Stairs or caffeine?

As I am not a caffeine aficionado I have been known to go walk up and down stairs at work when I’m having a particularly sleepy day, it turns out that stair walking may actually be more effective, at least more effective than low doses of caffeine at improving alertness. In a small study of … Continue reading

Do you have a concussion? Try testing your spit

For anyone who has had to do first aid on someone after they hit their head or make a decision about an athlete’s ability to continue to participate, or if you have had to decide yourself whether or not you may be suffering from a concussion yourself you know how much of a guessing game … Continue reading

Using DNA to see what bees do

To be honest, I had never thought about what we would do if bees and other pollinators disappear, despite knowing that they are currently under threat. But how do plants that depend on pollinators reproduce if the pollinators disappear? In various places throughout history, people had had to go out with tiny paint brushes and … Continue reading

Icing to increase flexibility?

I stumbled across an article today that seems to go against what I have always understood about stretching and flexibility. I have always been taught that to truly stretch you need to warm up your muscles first. Typically this was done by working the muscles at a lower intensity but I remember a physiotherapist telling … Continue reading
