Test your navigation skills

This week's New Scientist has a feature by Chris Berdik called Lost: "Birds, rats and hamsters are able to find their way around with consumate ease. So how come we can't navigate our way out of a paper bag?"

This is a very interesting article, especially if you've ever struggled to find your car in a car park. It features a report on "developmental topographical disorientation" as identified by Giuseppe Iaria of the University of Calgary and Jason Barton at the University of British Columbia in Vancouver.

You can test your own skills in association with their study here.
