Chemist Patrick Harran was nominated to become a fellow of The American Association for the Advancement of Science. However, the nomination will no longer proceed to his fellowship after a complete re-evaluation of the submission in light of the accidental death in 2008 of a 23-year-old researcher, Sheharbano Sangji, in Harran's lab. The AAAS is also now reviewing its procedures for its prestigious fellowships.
