Beagle's nose predicts few US polar bear cubs

Elvis, a 2-year-old beagle, sniffs polar bear protein samples at Iron Heart Performance Dog Center in Shawnee, Kan., Monday. Confirming pregnancies of the massive bears, a threatened species, has been difficult, and zoo officials say knowing can help make sure they and the mama bears are ready for birthing and raising cubs. Elvis has demonstrated 97 percent accuracy in positive identification of samples from pregnant females.
