What is it about?
"We’ve developed a way to 'fingerprint' artefacts using electricity, without damaging them. By 3D-printing a replica of an object, we can cancel out the confusion caused by its shape. This lets us see the 'DNA' of the material itself—helping archaeologists to characterise the materials used inmaking an object, and helping customs agents to distinguish between legal bone and illegal ivory."

Why is it important?
Compared to many existing methods of material identification, this method is less destructive and works in a very different way, offering significant new potential.
Perspectives
This was a new technique for me, and it was great to explore its potential in a diverse archaeological and scientific team.
