Dark-matter detectors usually conjure up images of large underground facilities, but relatively small quantum sensors such as atomic clocks and magnetometers have also joined the search for the elusive stuff. In this episode of the Physics World Weekly podcast, Andrei Derevianko at the University of Nevada, Reno explains how it is done.

We are also joined this week by Physics World columnist Caitlin Duffy, who is doing a PhD on superconductivity at the High Field Magnetic Laboratory in the Netherlands. Duffy talks about the benefits of moving country to pursue career opportunities and the professional and personal challenges of working abroad during the pandemic.

Finally, Physics World editors chat about the medical benefits of focused ultrasound and a new way of creating materials for twistronics.
