In Discover Magazine This Month: 20 Things You Didn't Know about Dogs

In June's Discover Magazine:

2 Bad astronomy: Sirius is the brightest star in the sky, but it is just one 10-billionth as bright as the sun and has no effect on our weather.

3 Nerd. Fido will touch his nose to a computer screen if it has a picture of a dog on it but not if it shows a landscape, University of Vienna researchers have found.

See "things" 4-20.
