There's a new light of hope in the Middle East. It's a scientific experiment called SESAME - intended to do world-class science and bring together researchers from divided nations. Its members include Palestine and Israel, Pakistan and Iran, Jordan, Egypt, and more. First conceived in the late 1990s, it has just seen the first spark of electricity flow through its high-vacuum steel pipes, last week, and first science should follow soon. The BBC’s Roland Pease paid his second visit to the SESAME campus just as the final pieces were being put in place, and met some of the key players, and heard their hopes.
