Preheat oven to 350 degrees. Combine the flours, bran, wheat germ, salt, and soda; make a well in the center. In a separate bowl, mix the remaining ingredients (yogurt, molasses, oil, raisins, nuts). Pour the yogurt mixture into the dry mixture, and stir just enough to moisten. Spoon the batter into 12 oiled muffin tins. Bake for 18 minutes or until a tester comes out clean.
