Excited to introduce our new photochromic probe OptoChol-1 - this sterol acts as an „efficacy photoswitch“ in TRPC3 and enables control over its channel function by light. Great job by Hazel Erkan-Candag in collaboration with T. Glasnov.

„Bildung ist eine zentrale Zukunftsinvestition“, schreibt das Bundeskanzleramt. Doch jetzt plant die Bundesregierung massive Kürzungen bei den Universitäten. Das gefährdet Forschung, Lehre und damit unsere gemeinsame Zukunft. mein.aufstehn.at/petitions/un...
Jetzt unterzeichnen: #unisretten – keine Kürzungen bei den Universitäten!
Die Regierung plant massive Einsparungen bei den Universitäten. Forschung, Lehre und freie Wissenschaft stehen jetzt auf dem Spiel.
