So much to think about after "Not all that glitters is green" by VerΓ³nica Zuccarelli Freire. A powerful reminder that the costs of the energy transition are not shared equally, especially in the #Andes. True climate action requires environmental justice.

Pit without finds = worthless pit? Investigating a Roman military camp from Caesar's Gallic Wars (58 – 51 BC) near Hermeskeil (Germany). This is one of the rare instances of published non-results for biomarkers. Not all good data validate your hypothesis!
