scibri writes "Omid Kokabee, a laser physics graduate student from the University of Texas who has been imprisoned in Tehran for the past 15 months, was sentenced to 10 years in jail on Sunday for allegedly conspiring with foreign countries against Iran. Kokabee was arrested in February 2011 while on a trip home, and charged with 'communicating with a hostile government' (i.e. Israel) and 'illegal earnings.' He has consistently denied the charges, and refused to speak at his trial, where no evidence against him was presented. Several international science groups, including the American Physical Society, have spoken up in his defense, and an online petition has been set up in support."
