Revisiting the Poor Man’s Majoranas: the spin–exchange induced spillover effect

This just in: using “Poor man’s Majoranas” as quantum spin probes could open a new frontier for #

Quantumscience! By harnessing the sensitivity of these systems, scientists have taken what was once considered a defect into a promising feature that enables them to function as precise quantum spin sensors ⚛️. Explore what this means for the future of quantumphysics here.

Oxytocin signaling in adipocytes is required for normal milk fat production

Online now: Li et al. show that sympathetic-derived oxytocin drives adipose lipolysis to supply triglycerides essential for neonatal growth during lactation. Adipocyte-specific oxytocin receptor (Oxtr) deletion impairs milk lipid content and offspring growth, revealing a new link between maternal oxytocin signaling in adipocytes, mammary metabolism, and neonatal nutrition.

Spatiotemporal molecular profiling of macrophage-fibroblast crosstalk defines checkpoints orchestrating onset and resolution of inflammation

Weishaupt, Chambers, et al. combine single-cell transcriptomic and epigenomic profiling with in vivo models to map the temporal dynamics of macrophage-fibroblast communication during inflammatory arthritis. They show that fibroblasts initiate inflammation, whereas monocyte-derived macrophages undergo transcriptional reprogramming into SPP1+ cells that actively promote resolution by restraining fibroblast pathogenicity.

AARS1-mediated lactylation of STAT1 drives immune evasion

Du et al. demonstrate that AARS1-mediated STAT1 K193 lactylation blocks JAK2 binding and STAT1 phosphorylation, which impairs IFN-γ signaling, reducing chemokine expression and promoting immune escape. Inhibition of this modification with the cell-penetrating peptide K193-pe restores IFN-γ responsiveness, enhances CD8+ T cell recruitment, and improves immune checkpoint therapy efficacy.
