This summer, physicists working on the LHCb experiment at CERN have announced the discovery of two new tetraquarks. In this week’s podcast, CERN’s Dan Johnson and Tim Gershon of the University of Warwick explain why these exotic hadrons are special and also chat about why LHCb is a champion when it comes to spotting tetraquarks.

Physics World’s Tami Freeman and Hamish Johnston also look at two new technologies that involve drawing or printing electronic circuits onto substrates including skin. It turns out that draw-on-skin medical sensors can be more reliable than contact-style devices such as fitness watches and have the added bonus of being able to speed up wound healing.
