• Trump’s mineral grab has all the elements of an earworm | Brief letters

    Trumped by Tom Lehrer | The wrong don | Gulf names | Cork house | DogeYour article, referring to rare earth elements including europium, dysprosium, gadolinium, praseodymium, holmium and ytterbium, was very enlightening (What are Ukraine’s critical minerals – and why does Trump want them?, 17 February). However, it was difficult for me to read, owing to the persistent intrusion of the earworm of a certain song by Tom Lehrer.

  • Country diary: Looking under lichen for a stranger’s name | Derek Niemann

    Beckington, Somerset: We’re digging up the past in a rural churchyard, connecting people to their long-lost family membersA “ten-pound pom” left Glasgow for Australia after the war and never saw her family again.

It would bring me in touch with a second cousin I never knew existed
