Dogs have been man’s best friend in the animal kingdom for thousands of years. They’re loyal companions and can even perform useful tasks like herding sheep and fetching slippers. They are easily attainable, cheap, and come in a variety of colors, shapes, sizes and temperaments. But in the past few years, a new breed of …

The instructive history of Clement Clarke Moore
History is full of artists in various disciplines who are most famous for things which they themselves considered of very little importance. Take Arthur Conan Doyle, for instance. He came to loathe his creation, Sherlock Holmes, going so far as to killing him…only to be forced by popular demand to bring him back again. Sir …
Scientific stain removal
I like to write about the latest discoveries in cosmology and particle physics. But not all scientific research is focused on these frontiers. Some of it is aimed as close as–well, that spot of mustard on your pants. Textile experts at Cornell University have published a pamphlet with detailed, laboratory-tested instructions on how to remove …
Joint replacement: what’s a nice joint like you doing in a dame like this?
“Gentlemen, we can rebuild him. We have the technology.” So began each episode of The Six Million Dollar Man. Twenty-some years after that TV series aired, we still don’t have bionic people capable of superhuman feats of strength and speed, but we do have lots of people walking around with artificial parts: especially, artificial joints. My …
Future energy sources
A lot of attention in Canada has been focused recently on the Kyoto Agreement to limit the emission of greenhouse gases. But scientifically, the goal for preventing possibly catastrophic global warming has been set far higher than Kyoto’s modest reductions. An article in the November 1 issue of Science sets out the challenges. Entitled “Advanced …
Reidel wine glasses
I had the pleasure of attending the International Festival of Wine and Food at the Banff Springs Hotel over the weekend. This event combines gourmet meals with tastings of some of the world’s best wines. But one tasting was very different: instead of tasting wine, those attending tasted glasses. They witnessed a demonstration by Georg …
Yet another column about tea
Tea is not only the most popular beverage in the world, it’s also good for you. Over the past 20 years, scientists have discovered potential benefits from tea against cancer, high blood pressure and infection. Now comes a report that tea may be an effective weapon in the fight against diabetes. First, some basic tea …
Trains
Trains have been on my mind lately, partly because I just completed a two-day trip from San Francisco by train, but also because trains have been in the news lately: Montreal’s Bombardier was in hot water over cracks in the suspensions of Amtrak’s high-speed Acela trains, McLean’s magazine recently ran a front-page story on …
Selling the moon
Humans will return to the moon next year, more than 30 years after the last Apollo astronauts left. Unfortunately, the new lunar visitors will have a large handicap that will hinder their exploration efforts: they’ll all be dead. The humans in questions will arrive in the form of small amounts of ashes from cremated remains, …
The Ig Nobel Prizes of 2002
It’s time again to announce the winners of some of the most prestigious prizes in science. No, not THOSE. I’m not talking about the IgNobel Prizes, awarded annually by the science humour magazine Annals of Improbable Research to those who have done something that first makes people laugh, then makes them think; or, to put …
Space: what’s NExT?
I’m a child of the Space Age, born a year and a half after Sputnik. Apollo 11 landed on the moon on my 10th birthday; Viking landed on Mars on my 17th. There is no doubt in my mind that if the human race is to survive, we must move out into space, to make …
Coast redwoods
Imagine a tree taller than the tallest building in Regina–by several stories; a tree as tall as a 30-story building. Imagine a tree trunk so massive you could easily live inside its hollowed trunk. Now imagine a whole stand of such trees, a valley filled with them. That’s the amazing reality of the Coast Redwoods. …
