Decades of observations tracked the fraying of once-friendly relations among Ugandan chimpanzees

To impede metastasis, researchers seek to develop novel treatments that disrupt tumor cell clusters

The heart’s faint magnetic signals can’t be detected at large distances, researchers say

Disruption of intestinal ecosystem could contribute to diabetes and other health issues, scientists say

Aging has long been associated with oxidative stress, yet its underlying metabolic drivers remain unclear. Liu et al. identify a conserved, iron-driven lipid peroxidation of primate aging mediated by ACSL4 and demonstrate that vitamin C directly suppresses this process, offering a translatable strategy to mitigate age-associated functional decline.

In a recent Cell Press Blue paper, Zhang et al. identify two polyunsaturated lipids that selectively eliminate senescent cells by inducing ferroptosis, uncovering this iron-dependent cell death pathway as a vulnerability for senescent cells. Their findings position ferroptosis induction as a promising strategy for targeting senescence and aging-associated diseases.

Tissue homeostasis emerges from mechanical feedback loops balanced by cell loss and proliferation, a balance that in postmitotic tissues must be maintained without compensatory proliferation. Yet how these tissues preserve mechanical homeostasis and how this challenges function in ageing remains unclear. To establish the relationship between cell density, mechanical homeostasis, and function, we induced age-mimicking cell loss in a postmitotic retinal pigment epithelium (RPE) in vitro. This...

Cytokines are essential mediators of immune functions and regulate many other biological processes, ranging from fetal development to ageing. Dysregulation of cytokine responses can substantially increase the risk of disease and so their activity requires tight control. The formation of cytokine homodimers, heterodimers and multimers has evolved as a versatile mechanism to regulate cytokine biology, in which multimerization can enable or attenuate their activity, diversify signalling outcomes...

MicroRNAs (miRNAs) regulate gene expression and can influence processes such as inflammation, metabolism, and aging. This study assessed the effects of miR-181a-5p and miR-1249-3p mimics on the transcriptome of visceral adipose tissue in middle-aged females mice. Mice received intraperitoneal injections of either miR-181a-5p, miR-1249-3p, or vehicle control, followed by transcriptomic and metabolic analyses. Both treatments significantly reduced fasting blood glucose levels and promoted...

Oocyte quality, a critical determinant of female reproductive potential, experiences a progressive decline with age, largely driven by the cumulative effects of oxidative stress and mitochondrial dysfunction. This review thoroughly synthesizes the latest evidence concerning the molecular, cellular, and environmental factors that disrupt redox homeostasis within oocytes. It particularly highlights the pivotal roles of reactive oxygen species, impaired mitochondrial metabolism, epigenetic...
