Turbulent Gas-rich Disks at High Redshift: Origin of Thick Stellar Disks Through 3D “Baryon Sloshing”

Joss Bland‐Hawthorn, Thor Tepper-García, Oscar Agertz et al. · 2025 · The Astrophysical Journal

Abstract In response to recent observations from JWST and Atacama Large Millimeter Array, we explore a new class of dynamically self-consistent models that mimics a plausible progenitor of the Milky Way over a wide range of disk gas fractions, f gas . The high gas surface densities encourage vigorous star formation, which in turn couples with the gas to drive turbulence. We show that this coupling through momentum recoil drives a random walk of the baryonic potential minimum with respect to total gravitational potential, Φ tot ( R , ϕ , z ). The amplitude of the bulk motion depends on the feed

Dasatinib and quercetin senolytic treatment delays early onset intervertebral disc degeneration in SM/J mice

Emanuel J. Novais, Olivia K. Ottone, Sanjana Jagannath et al. · 2026 · Bone Research

Genetic background is a major determinant of disc degeneration, a leading cause of chronic back pain and disability. Herein, we demonstrate that premature disc cell senescence contributes to early-onset degeneration in SM/J mice and test two systemic senotherapeutic strategies to mitigate it: Navitoclax (Nav.) and a cocktail of Dasatinib and Quercetin (DQ). While Nav. treatment did not improve severe degeneration in SM/J mice or senescence status, DQ-treated mice showed lower grades of degeneration and a decreased abundance of senescence markers, including p19ARF, p21, and the senescence-assoc

Unraveling Chronic Pain: From Mechanisms and Risks to Diagnosis and Treatment

Xiaofeng Dai, Chongxiang Wang, Ping Jiang et al. · 2026 · MedComm

Chronic pain is a globally prevalent and complex condition, encompassing three primary subtypes, that is, nociceptive, neuropathic, and nociplastic, each with distinct biopsychosocial mechanisms. Chronic pain was historically viewed as a monolithic symptom and managed with opioid-centric models, causing widespread therapeutic failure. While recognition of its heterogeneity has driven a paradigm shift toward precision medicine, tailoring multimodal strategies to the dominant pain mechanism, critical challenges persist. These include difficulty in identifying treatable root causes, limited long-

Endothelial STING and STAT1 mediate IFN-independent effects of IL-6 in an endotoxemia-induced model of shock

Nina Martino, Erin Sanders, Ramon Bossardi Ramos et al. · 2025 · Journal of Clinical Investigation

Severe systemic inflammatory reactions, including sepsis, often lead to shock, organ failure, and death, in part through an acute release of cytokines that promote vascular dysfunction. However, little is known about the vascular endothelial signaling pathways regulating the transcriptional profile in failing organs. Our work focused on signaling downstream of IL-6, due to its clinical importance as a biomarker for disease severity and predictor of mortality. Here, we show that loss of endothelial expression of the IL-6 pathway inhibitor SOCS3 promoted a type I IFN-like (IFNI-like) gene signat
