Rebecca Lai can't wait to see little booms and bursts of science lighting up the skyline each July 4. Her fascination with fireworks sparked around age 5 as she watched Chinese New Year celebrations over Victoria Harbor in Hong Kong. At UNL, she's translated her love for fireworks — and chemistry — into a course based on J.K. Rowling's Harry Potter series.

A construction crew removed a time capsule from the cornerstone of Avery Hall on May 12. Records show that the capsule contains variousf items, including a photo of Rachel Lloyd, the University of Nebraska's second chemistry professor and first American woman to earn a doctorate in chemistry. Mark Griep hopes to use the historic items in an October celebration of Lloyd's contributions to the field of chemistry.
