Young girls are creaming the boys in science, up north in Canada.

Five years ago, boys made up 55 percent of the competitors at the annual Canada-Wide Science Fair, a national competition where youth in grades 7 to 12 compete against other regional representatives. After a steady decline, this year boys are in the minority at 44 percent. Girls are also claiming the lion's share of prize money available each year: Eight of the last nine overall winners have been female.
