Cryo-electron microscopy structures of three large ornate natural bacterial RNA molecules reveal their quaternary structures and intra- and intermolecular interactions that stabilize them.

Cobalt-based catalysts are regarded as a potentially cheaper alternative to platinum and chromium systems for the non-oxidative dehydrogenation of propane, although they often feature lower performance. Now mixed-valence Co^0/IIO_x clusters supported on silicalite-1 are identified as a competitive system for this reaction.

MASH is driven by the secreted GPNMB ectodomain, which binds hepatocyte RYK to activate ERK1/2 and promote lipid uptake and lipogenic programs; blocking the GPNMB–RYK axis prevented and treated MASH in preclinical models.

CD44 expressed by fibroblastic reticular cells in secondary lymphoid organs regulates trafficking of dendritic cells, and thus has an essential role in the priming of T cells and the adaptive immune response.

The APOE-ε4 allele is the strongest genetic risk factor for late-onset Alzheimer’s disease, but it is not deterministic. Here, the authors show that common genetic variation changes how APOE-ε4 influences cognition.

The CATS Net framework models how abstract concepts emerge from sensory experience. Aligning with human brain activity and enabling knowledge transfer, it provides a unified framework for understanding conceptual intelligence in both humans and AI.

CD38 is highly expressed by antibody-secreting cells (ASC) and depleting antibodies targeting CD38 have the potential to treat autoimmune diseases with ASC involvement.
