Uncovering Australia's Prehistoric Humans: Latest Discoveries.

Researchers and Aboriginal rangers are using electrical resistivity tomography to model a buried ancient landscape in Australia's Northern Territory, which could reveal new insights about the country's first inhabitants and the rock art they created. The team's paper, published in PLOS ONE, shows how environmental changes at the lagoon correlate to fish, crocodiles, and birds that appeared in artistic depictions. The technique involves mildly electrocuting the ground, then measuring the waves as they pass through to find out what's below. However, some archaeologists are skeptical that anything substantial remains at the site.
