Helikite up, science on! On board FOREL in South Greenland, the GreenFjord team deployed the helikite and carried out lake sampling, incubations, drones, and a science meeting — all framed by stunning views. 📸 Julia Schmale & team @epflcampus #FOREL2025 #GreenFjord #EPFL

1/3 🚨 Published today in @Nature We’re thrilled to celebrate the latest work by our colleague Dominik Gräff! 🎉 Using seafloor fiber-optic sensing, his team watched Greenland’s glaciers calve in real time & found something surprising 🌊🧊 📸: D. Gräff

Depuis bien longtemps, la Berne fédérale se trompe sur la manière dont la Suisse est perçue aux Etats-Unis. Elle surestime sa position et ses leviers. Contrairement à d’autres pays, elle néglige l’importance du lobbyisme à Washington. Et ça a commencé bien avant Trump. 👇
