A thin skim of ice formed on the Bras d'Or Lake this weekend, and the forecast week of bitter cold and light winds promises to deepen and strengthen its wintery cover. Forty years ago, this was an all-but-annual occurrence. In the middle decades of the 20th Century, Victoria County's legendary physician C. Lamont MacMillan routinely crossed the lake in a homemade half-track to reach ill patients in the depths of winter. But as our climate has changed, the frozen lake has become a rarity. Consider this a placeholder for a compilation, coming soon, of the outraged comments that flooded in from...

Scientific American calls bullshit on wind chill: [I]f the air temperature is, say, 15 degrees F, and a 20–mile per hour wind makes the wind chill –2 degrees F, would the temperature of your exposed skin drop to that temperature? No. Your skin temperature cannot drop below the actual air temperature. The coldest your uncovered face could get would be 15 degrees F whether the wind is calm or howling at 40 mph...

The International Symbol of Accessibility (ISA), more widely but less correctly known as the handicapped sign, is evolving. The original symbol (far left), designed by Susanne Koefoed in 1968, was pretty much just a stylized wheelchair. The International Commission on Technology and Accessibility (ICTA), a committee of Rehabilitation International, humanized the it by adding a head (second from left). This is the icon we are most familiar with. Critics complain that its static nature stigmatizes the wheelchairs as instruments of helplessness and passivity.  In 2005, VSA, an international organization on arts and disability, produced a more active icon implying self-propulsion (third from left). At least one store,...

This winter, Contrarian hosted an interesting discussion about whether Down syndrome needs a cure. Now reader Denis Falvy offers an intriguing footnote. It seems that people with Down syndrome rarely get tumors. Recent research at Children's Hospital in Boston, reported in the journal Nature, suggests that a gene (gene 231) on the extra chromosome (chromosome 21) carried by people with DS may inhibit cancer by blocking the activity of a protein tumors need to grow. Money quote: The gene suppresses the growth of new blood vessels that cancers need by blocking the activity of the protein calcineurin, suggesting a new target for...

Jenn Power, Community Leader of L'Arche Cape Breton, mother of twin boys with Down syndrome, and—disclosure—Contrarian's daughter-in-law, had an interesting reaction to news that a Stanford University research team has made headway toward a potential treatment for the intellectual impairment that is one of Down's symptoms: She welled up with tears. The researchers probed the brains of mice genetically engineered to develop a rodent version of Down syndrome. They found that a region known as the hippocampus lacked a neurotransmitter that enables the brain to perform contextual learning. This is the process of gaining and applying knowledge in real-world situations—things like...

A very sad update: The woman attacked by two coywolves succumbed to her injuries overnight. Deepest sympathy to her family and friends for their unimaginable loss. - - - The shocking news that a 19-year-old Toronto-area woman was attacked and "very, very seriously" injured by a pair of coyotes in the Cape Breton Highlands National Park this afternoon will undoubtedly focus attention on recent reports that Eastern Coyotes are in fact a hybrid of coyotes and wolves, or coywolves. We offer heartfelt hopes for a speedy and complete recovery for the unidentified woman, who was hiking on the popular and well used Skyline...
