Nature: During the English Civil War (1641–52), a warship, thought to be the Parliamentarians’ Swan, sank off Scotland’s west coast. Among artifacts retrieved from the wreck in the 1990s was a barnacle-encrusted pocket watch. Now, thanks to a compact CT scanner built by X-Tek Systems of Tring outside London, a team from the National Museum of Scotland has peered through the barnacles to discover the watch’s movement. Jo Marchant’s report for Nature includes a movie that presents a “fly through” view of the CT data.
