New and exciting technologies feature in this episode of the Physics World Weekly podcast.

Our first guest is the neuroscientist and physicist Jelena Lazovic Zinnanti, who recalls how she discovered (by accident) that nanometre-sized diamond particles shine brightly in magnetic resonance imaging (MRI) experiments. Based at Max Planck Institute for Intelligent Systems, she explains how this diamond dust could someday replace gadolinium as a contrast agent in MRI medical scans.

This episode also features an interview with Mahdi Bodaghi of Nottingham Trent University, who is an expert in 4D and 3D printing. He talks about the engineering principles that guide 4D printing and how the technique can be used in a wide range of applications including the treatment of coronary heart disease and the design of flatpack furniture. Bodaghi also explains how 3D printing can be used to create self-healing asphalt.

Mahdi Bodaghi is on the editorial board of the journal Smart Materials and Structures. It is published by IOP Publishing, which also brings you Physics World.
