Making Sense of Bifurcation Diagrams: A New Framework to Understand the Roles of Clouds and Bare Sea Ice for Waterbelt States

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract Earth has experienced several pan‐glaciations in its history, often interpreted as hard Snowball Earth periods with global ice cover. Alternatively, waterbelt states with a narrow equatorial strip of ice‐free ocean provide a compelling explanation for the survival of life during these extreme glaciations.

Identifizierung eines Aktivitätsselektors, der die Nitrosoaktivität in bakteriellen Typ‐III Kupferenzymen kontrolliert

open access: yesAngewandte Chemie, Volume 137, Issue 26, June 24, 2025.
Ein kleiner, aber entscheidender Unterschied: Typ‐III‐Kupferenzyme, wie Tyrosinasen (TYRs) und o‐Aminophenoloxidasen (AOs), katalysieren die Oxidation von o‐Aminophenolen (AP) zu Chinoniminen. Im Gegensatz zu TYRs können AOs AP weiter zu Nitrosophenolen oxidieren.
