Abstract Cover cropping is mainly used to prevent soil erosion, but the effects of individual cover crops on the subsequent soybean [Glycine max (L.) Merr.] are hardly known. Therefore, two annual field trials with 15 cover crop species and bare fallow as control were conducted in semi‐arid East Austria in 2016 and 2017.

Corramycin ist ein neuer Naturstoff, welcher von dem Myxobakterium Corallococcus coralloides produziert wird. Seine Struktur sowie die außergewöhnliche Total‐ und Biosynthese des Antibiotikums werden hier zum ersten Mal beschrieben. Corramycin zeigt keine Zytotoxizität und keine Kreuzresistenz mit gängigen Antibiotikaklassen.

Wasserstoff ermöglicht Teile des reduktiven Krebs‐Zyklus unter Katalyse von Metallen oder Meteoriten
Wasserstoff ist ein geologisches Reduktionsmittel, das den Stoffwechsel moderner Organismen antreibt und möglicherweise auch den Stoffwechsel des letzten universellen gemeinsamen Vorfahren aller heutiger Lebewesen ermöglicht hat. Hier zeigen wir, dass katalytische Mengen von Übergangsmetallen oder kleine Mengen von Meteoritenpulveren es ermöglichen ...
