The highly detailed images have revealed infrastructure that excavations would have missed.

A study in Scientific Reports concerns a genomic analysis on medieval skeletons from a Vilnias in Lithuania. It was a plague burial but one of the skeletons showed a signal of something else - a pathogen of a disease somewhat similar to syphillis. The prevailing opinion is that the first outbreak of syphillis in Europe coincided with Carles VIII's seige of Naples in 1495  when a debilitating disease erupted amongst his soldiers. This occurred shortly aftger Columbus has his ships crews had returned from the Amricas. The researchers went on to show th disease had an origin in a tropical climate and was common to humans and primates. It turns out it arrived in Europe from West Africa - as a result of the slave trade. However, this particular disease, although closely related to syphillis, is not syphillis, so the search is still on.

They still survive in parts of Oceania (or the South Pacific).
