Cambridge scientists have used downscaled laboratory models to show how sand dunes move through a landscape, revealing the conditions that determine whether they will pass through hurdles in their path – like pipelines or walls -- or get stopped in their tracks.
Even though they are inanimate objects, sand dunes can ‘communicate’ with each other, researchers have found. A team from the University of Cambridge has found that as they move, sand dunes interact with and repel their downstream neighbours.
The identification of rock art found in Farafra as Neolithic adds substance to the argument that Egypt drew on cultural influences from Africa as well as the Near East. At a talk tonight (19 May, 2014) archaeologist Dr Giulio Lucarini will talk about his fieldwork in the Egyptian Western Desert and show images of newly-identified Neolithic drawings to a public audience for the first time.
