The origins of Gullah-speaking African-Americans, an old antibiotic as a new drug candidate for Duchenne muscular dystrophy, and a powerful cellular self-defense mechanism against breast cancer are among the five "Hot Picks" selected by the Public Information Committee (PIC) from the more than 400 "late abstracts" to be presented today at the American Society for Cell Biology's 43rd Annual Meeting. Other PIC "Hot Pick" papers focus on a unique set of microRNAs that could identify human embryonic stem cells and a new therapeutic target for treating African Sleeping Sickness.

"Late Abstracts have been one of the great secrets of the ASCB meeting," explains PIC Chair Kathy L. Wilson. "They are submitted months after the regular abstract deadline and always presented on the last afternoon so Late Abstracts are often the freshest and the most unexpected work at the ASCB Annual Meeting. The 2003 Hot Picks list is the PIC's attempt to share that secret." All 417 Late Abstracts submissions were given a double "peer-screening" by PIC members to identify the work with the greatest news value or significance.
