The new TSN.ca site relaunched today with a new look (which, at launch ran the same main photo as Canada’s other big sports site was) and a new mandate. The site now incorporates all of content from six television channels: TSN, RDS, ESPN Classic Canada, NHL Network, WTSN, and OLN.

One thing that always got me about Spider-Man was his ability to climb walls. I don’t know why that one fact bothered me in a universe that allowed a teenager bitten by a radioactive spider (yes, I’m old-school on this) to gain a whole range of superpowers. Now, though, a plausible explanation has been revealed.

Scientists have discovered how geckos (the lizard, not the layout engine behind Mozilla) can climb glass: apparently the hairs on their feet form electrodynamic bonds with the surface. Each tiny hair has 1,000 pads on its tip, and each tip is only only 200 billionths of a metre wide — below the wavelength of visible light.

The effect has been duplicated by the scientists using other substances and may lead to “dry, self-cleaning adhesive that works under water and in a vacuum” or the coolest Hallowe’en costume in the world.
