Sudoku Champ Eyes Tougher Puzzles

Beating all comers—for the second year in a row—at the world's top sudoku tournament is nothing to scoff at, but champ Thomas Snyder has loftier goals, the San Jose Mercury News reports. The 28-year-old Stanford scientist is hoping he can solve complex DNA puzzles instead: "I hope I can take advantage of my skills and be someone who changes people's lives."

The bioengineering post-doc says he wants to find a method to help diagnose, and perhaps prevent, gene-borne illnesses; sudoku has sharpened his mind for the task. Snyder plans to keep at the DNA puzzle, but he expects his sudoku dominance to wane: I don't know if I'll hold this position for all of my life—but for now, I think it's a real hoot."
