Cover your cups of coffee and tea. Ben Chun Liu, the UCSF urology researcher who allegedly poisoned his colleague because he was "stressed," is free today. A San Francisco judge ordered him free while lab tests continue. Liu is awaiting trial for attempting to murder his coworker, Mei Cao, 44, by adding a hint of ethidium bromide into her drinking cup at her work station. He must return to court on December 18.
