Popping up everywhere, as AP bulletins do, is this story about a bath complex once owned by Quintus Servilius Pudens, a buddy of the emperor Hadrian. It was unearthed at the big Parco degli Acquedotti dig site, in the suburbs south of the old city. The American Institute for Roman Culture, which runs the dig, has a page which suggests this was actually discovered last year (assuming this is the same "imperial" bath complex mentioned on that page).
With a hat tip to Adrian Murdoch, here's a Google Maps link to the Parco degli Acquedotti. Many previously excavated areas are visible, and if you pan back, the American school's presence is betrayed by the baseball fields (!) to the south. So much for "when in Rome..."
