OK, here we go. First, to the Irish Sea to hear about a new tidal turbine technology. Then, we'll examine the recent hacking of some Darfur-related websites. Could the Chinese be involved? Then, to the Iranian city of Qom to hear about the digitization of Muslim scholarship there. We'll follow that with a report on a new old-school campaign to raise awareness of an imprisoned Egyptian blogger. And we'll end in Barcelona with a report on the birth of a new instrument.
