  • Demonstration of how much mercury is released during dental drilling

    In the offices of North Carolina dentist Matthew Young, retired Chairman Boyd Haley of the University of Kentucky’s chemistry department assists in demonstrating how much mercury is released during drilling to remove a mercury filling from a tooth placed in a mannequin. Unlike in many dental offices, the experiment did not use a high-speed vacuum to suction waste from a patient's mouth. This is a scenario that happens everyday in dental schools and some dental offices.

  • National Zoo's panda takes a roll in the snow

    One of the pandas at the National Zoo in Washington had some fun in the snow on Saturday, December 9. Mei Xiang frolicked and rolled down the hill as spectators watched. The zoo’s giant pandas are native to the cold climate of China’s western mountains and are more active during the winter month, the zoo said. The National Weather Service reported that just over two inches of snow fell at the zoo on Saturday.
