The Cover Feature shows a stunning event that takes place every few years in Patagonia, Argentina: the breaking of the Perito Moreno glacier. Such impressive spectacle is triggered by the pressure developed by the glacier, pushing water through the glacier tunnels underneath, which eventually causes tunnel growing and finally a dramatic collapse as the barrier breaks. In the same way, an interesting domino process towards useful thiosugars is initiated by the strain release involved in epoxide opening. More information can be found in the Full Paper by R.A.
