To weed or not to weed

A few years ago I moved into a neighbourhood of lush lawns. My direct neighbour is a retiree and spends excessive time managing his many different flower beds and his lawn. It looks awesome, so long as you like the manicured look. As I walk down the street on my way to the bus each … Continue reading

No straight answer

A few weeks ago I wrote two posts on synthetic versus cotton clothing and synthetic versus cotton wound dressings. Those came out quite squarely on the side of the synthetics. But nothing in life is ever that simple. The other side of the discussion are the environmental and social impacts of cotton versus synthetic clothing … Continue reading

Science Fair

It is impossible to write on every science topic out there, which is awesome. There is so much science going on, in all parts of the world. Some of it is done in universities or in organizations but a lot of it happens in other spaces where someone sees a need or asks a question … Continue reading

Sport under threat from climate change

During my doctoral research one of my participants brought in a photo of her sand boarding. It was snow boarding on sand dunes and we talked about the potential impacts of climate change on sport, particularly winter sport. Check out the website for my research here. The cross country ski program in Special Olympics Alberta … Continue reading

Whiter than white? Not with LEDs

I have bought your paper with a high percentage of post-consumer recycled content for several years. I don’t typically notice that anything is different until I see my paper up against someone else’s; that’s when I see that white is not always white. But it turns out that manufacturers of things like paper and laundry … Continue reading

Bird attack

My lawn is a pretty good space for urban wildlife watching. We have a snowshoe hare highway, mice under the tree, and squirrels in the trees. And many many birds, none have hit the window recently.  One of those birds dive bombed the lawn to get at something small that was living under the snow. … Continue reading

Daylight savings time

I don’t like daylight savings time. Actually, to be more accurate, I prefer daylight savings time (DST) but don’t like switching on and off of it. So with the time change this past weekend I decided to look into the benefits, or lack thereof. Switching from DST to standard time is associated with an 11% … Continue reading

Grass, artificial turf, and nature connection

I saw today that one of Edmonton’s city councillors wants to look at replacing some of the city’s sports fields with artificial turf. The part of me that enjoys being in nature and wants all people to have more opportunities to connect with nature is struggling. I feel like there are many different factors in … Continue reading

Birds and windows

I had a traumatic morning, but not as traumatic as it was for the bird who hit my window. After a loud thump, I knew what had happened. We’ve had a few birds tap the window before but this one didn’t sound good. Sure enough when I looked outside the bird was alive but on … Continue reading

Floating photovoltaics: Do they reduce evaporation?

I saw this interesting article about installing floating photovoltaics on Lake Mead and Lake Powell in the U.S. as a means of generating power using renewables and reducing some of the significant evaporation from the two lakes. It makes sense that the solar panels will generate electricity, but I’m curious about two of the claims: 1) how much … Continue reading
