As AI—and the ethical debate surrounding it—accelerates, scientists argue that understanding consciousness is now more urgent than ever. Researchers writing in Frontiers in Science warn that advances in AI and neurotechnology are outpacing our understanding of consciousness—with potentially serious ethical consequences.
One of the most common antidepressants, sertraline, contributes to a modest improvement in core depression and anxiety symptoms, including low mood, within two weeks, finds a new analysis of a major clinical trial led by University College London (UCL) researchers.
Numerous studies have consistently demonstrated that a considerable proportion of patients with major depressive disorder (MDD) frequently exhibit pronounced dyslipidaemia. However, the causal dynamics between MDD and dyslipidaemia remain elusive. To comprehensively disentangle the genetic causality between MDD and various phenotypes of blood lipids, thereby facilitating the advancement of management strategies for these conditions.
A recent review article published in Molecular Biomedicine highlights that a comprehensive understanding of reactive oxygen species (ROS) homeostasis is opening new avenues for therapeutic innovation. The review begins with the core principles and molecular mechanisms that govern ROS generation, scavenging, and organelle crosstalk, and then systematically elaborates how ROS dynamics influence cellular metabolism, growth, differentiation, and programmed cell death. It critically assesses how disruption of ROS homeostasis contributes to the pathogenesis of diverse diseases across the lifespan and synthesizes current and emerging strategies for modulating ROS levels. Emphasizing the need to resolve challenges of specificity and context-dependence, the authors call for the development of precise biomarkers and the exploration of combination approaches—such as pairing ROS modulators with immunotherapy or metabolic agents—to enhance efficacy. By framing ROS as both indispensable signaling mediators and potential toxins, the review argues that targeted modulation of ROS homeostasis could reshape future precision medicine, while urging more translational studies to validate and optimize these strategies for clinical use.
