Their analysis has managed to pinpoint the origin of the ivory and tell a sad story of forest elephants assumed but never before documented in such precise detail. The finding makes it clear that ivory may have pre-dated European trans-Atlantic slavery as a central driver in maritime trading systems connecting Europe, Africa and Asia.
The Portuguese completed the first transatlantic slave voyage to Brazil in 1526, quite possibly on the back of an already established ivory trade. Forty years earlier they had reached the Congo River and were trading and plundering along the West African coast. In 1482 they built a fort at an established trading post at Elmina, on the south-western edge of the kingdom of Dahomey.

Physicists have spent decades uncovering similarities in how disordered materials deform. Now they are trying to apply these results to the design of new materials.

Karin Dahmen loves noise. A theoretical physicist at the University of Illinois at Urbana-Champaign, she has spent most of her career studying the “crackling noise” emitted by different materials when they deform. The noise emitted when a piece of paper is crumpled, for example, is a series of discrete snaps that vary in loudness. If you were to plot the number of snaps for each loudnes
