The famous and gigantic Perito Moreno glacier in Argentina. We can see glaciers thinning and retracting all over the world. Your grandchildren might never see one in their lifetime. / Der berühmte und gigantische Perito Moreno Gletscher in Argentinien. Wir sehen Gletscher auf der ganzen Welt dünner werden, und auf dem Rückzug. Vielleicht werden unsere Enkelkinder Gletscher nur von Bildern kennen. #PeritoMoreno#Glacier#Argentina#Nature#HumanInfluence#Landscape#EarthFromSpace#ISS#ESA

Tackling Parkinson’s disease from space. In weightlessness, the LRRK2 protein crystals causing the disease can be grown artificially, much bigger than on Earth. We need these to search for an inhibitor drug. @ISS / Angriff auf Parkinson’s Krankheit. In der Schwerelosigkeit können wir die zerstörerischen LRRK2 Proteinkristalle viel grösser züchten als auf der Erde. Und diese brauchen wir, um nach wirksamen Medikamenten zu suchen.
