How Canada can save the music industry
Hey, it’s a relevant question — particularly since astronomers at the Chandra X-ray Observatory have found that the Perseus galaxy is emitting a B-flat drone. Mind you, it’s 57 times lower than the lowest note on a piano, so unless you have subwoofer in your stereo that’s oh, about four million feet tall, you’re unlikely to hear this particular note sampled in the latest electroclash compliation.
And hey? What does the Perseus nebulae care about musical trends? It’s been humming that note for 2.5 million years — the longest-running celestial Top-40 hit, as it were. If you want the details on how they managed to hear this tone, check out the story at Space.com:
The Perseus cluster is the brightest known in X-rays, making it a good target for study. It has two large, bubble-shaped cavities that extend away from a central black hole. The cavities are formed by jets of material ejected from the black hole’s surroundings, and the jets have been suspected of heating the outlying gas. But scientists couldn’t see how.
A special image-processing technique was used to bring out subtle changes in brightness that revealed the presence of ripples — the sound waves.
Fabian and Allen figure the sound waves, observed spreading out from the cavities, heat the gas. The amount of energy involved is staggering, equal to what would be produced if 100 million stars exploded.

From an interview with ethnobotanist and anthropologist Wade Davis:
One of the cultures you celebrate in Light at the Edge of the World is the Inuit. What do you most admire about them?
Davis: The Inuit didn’t fear the cold; they took advantage of it. During the 1950s the Canadian government forced the Inuit into settlements. A family from Arctic Bay told me this fantastic story of their grandfather who refused to go. The family, fearful for his life, took away all of his tools and all of his implements, thinking that would force him into the settlement. But instead, he just slipped out of an igloo on a cold Arctic night, pulled down his caribou and sealskin trousers, and defecated into his hand. As the feces began to freeze, he shaped it into the form of an implement. And when the blade started to take shape, he put a spray of saliva along the leading edge to sharpen it. That’s when what they call the “shit knife” took form. He used it to butcher a dog. Skinned the dog with it. Improvised a sled with the dog’s rib cage, and then, using the skin, he harnessed up an adjacent living dog. He put the shit knife in his belt and disappeared into the night.

“Video from a camp north of Toronto in December 2005 shows a car spinning around in a nearby, snow-covered parking lot. Prosecutors characterized that as special driver training but the defense, and many outsiders, said it was nothing more than “cutting doughnuts,” a favorite winter pastime of young Canadian motorists.” - A key piece of evidence submitted in the trial of a gang of alleged young Canadian terrorists.
