Open AccessUncovering spin-orbit coupling-independent hidden spin polarization of energy bands in antiferromagnets
Many textbook physical effects in crystals are enabled by some specific symmetries. In contrast to such ‘apparent effects’, ‘hidden effect X’ refers to the general condition where the nominal global system sym...

Open AccessPhylogenetically and catabolically diverse diazotrophs reside in deep-sea cold seep sediments
Microbially mediated nitrogen cycling in carbon-dominated cold seep environments remains poorly understood. So far anaerobic methanotrophic archaea (ANME-2) and their sulfate-reducing bacterial partners (SEEP-...

Open AccessUSP14-regulated allostery of the human proteasome by time-resolved cryo-EM
Proteasomal degradation of ubiquitylated proteins is tightly regulated at multiple levels1–3. A primary regulatory checkpoint is the removal of ubiquitin chains from substrates by the deubiquitylating enzyme ubiq...

Open AccessAlternative polyadenylation drives genome-to-phenome information detours in the AMPKα1 and AMPKα2 knockout mice
Currently available mouse knockout (KO) lines remain largely uncharacterized for genome-to-phenome (G2P) information flows. Here we test our hypothesis that altered myogenesis seen in AMPKα1- and AMPKα2-KO mic...
