Hydrogen‐Producing Catalysts Based on Ferredoxin Scaffolds
Advanced Science, EarlyView.Selected plant‐type ferredoxins that lack their natural [2Fe‐2S] clusters functionally bind a hydrogenase active site cofactor and act as hydrogenases themselves. In combination with photosystem I, the light‐dependent H₂ evolution almost matches the H₂ production rates of the natural system.

Activation of Kir4.1 Channels by 2‐D08 Promotes Myelin Repair in Multiple Sclerosis
Advanced Science, EarlyView.Multiple sclerosis causes myelin loss and neurological dysfunction. This study shows that 2‐D08, a small molecule targeting Kir4.1 channels, promotes OPCs differentiation via FYN tyrosine kinase phosphorylation and the FYN/MYRF pathway. It significantly improves myelin repair and motor deficits in EAE mice and marmosets, highlighting its potential as a

Stellar Photometry at the Crossroads of the Two Centuries
Open Astronomy, 2003 In the last century photometry was recognized as a powerful method for investigation of physical parameters of stars and of interstellar matter. Photometric investigations now cover the spectral range from the far ultraviolet to the far infrared.

Advanced Science, EarlyView.This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Theranostic Toolbox for Neutrophil Functionalization
Advanced Science, EarlyView.Here, neutrophil‐specific fluorine nanoparticles additionally equipped with either activating or inhibiting peptides for a background‐free 19F MRI‐based nanotheranostic approach are engineered. It is demonstrated that this approach is suitable to visualize and concomitantly direct neutrophil functionality depending on the specific requirements to ...
