Un gruppo di scienziati ha scoperto antichi crostacei nelle profondità del lago Mercer, al Polo Sud. Questo specchio d'acqua situato al di sotto di una spessa calotta di ghiaccio non era mai stato esplorato prima direttamente, se non attraverso piccolissime sonde. Questa volta i ricercatori sono riusciti a farsi strada scavando uno stretto corridoio nel ghiaccio.
La scoperta, fatta a circa un chilometro di profondità, li ha lasciati a bocca aperta. Gli studiosi dovranno ora capire come hanno fatto questi organismi a raggiungere un luogo talmente inospitale e a che periodo storico risalgono.
