We are pleased to say that Will Hutchison’s recent paper in Nature Communications was picked up by a major topics journal called ‘The Conversation’ who invited us to produce a layman’s summary of the work. It is targeting a relatively young audience, so the bigger picture science is presented. Anouk came up with the M&Ms analogue for isotopes! We placed the work within a broader context of our research into critical metals in alkaline igneous rocks.
