Researchers tested whether squalene and saponin—two natural compounds—could reduce aging-related damage in rat brains exposed to a chemical that mimics aging. The combination treatment reduced oxidative stress markers and boosted protective proteins, but this is …
Researchers discovered that when older adults receive a vaccine with an immune-boosting adjuvant, their bodies generate a specific type of immune cell (TH17) that compensates for age-related weakening of other immune defenses. This finding explains …
Researchers synthesized a new class of hybrid molecules combining an anti-cancer drug scaffold (sulfadiazine) with a 5-oximidazoline ring structure, and found that one compound (7l) killed liver cancer cells in the lab and extended survival …
This review examines how age-related declines in hormones like testosterone, growth hormone, and thyroid function create a perfect storm for simultaneous fat gain and muscle loss—a condition called sarcopenic obesity. The authors argue that understanding …
This small study found that hospitalized older people experiencing delirium had higher glutamate levels in their brain tissue compared to those without delirium, suggesting a potential toxic process that could explain cognitive decline after delirium. …
Researchers studied an unusually long-lived population of invasive bighead carp and found they survive at very high rates (>95% annually) but grow slowly, with implications for predicting how invasive species establish themselves. This work has …
This article reviews malnutrition as an under-recognized health crisis in aging UK populations, driven by physiological, social, and economic factors. The author calls for better screening, evidence-based interventions, and collaborative clinical-policy action to improve longevity …
This philosophical essay argues that later life should be understood as a valuable life stage defined by agency, meaning, and relationships—not reduced to health risks or frailty. The authors draw on Cicero's ancient treatise to …
Researchers discovered that fibroblasts from wild Mediterranean mice (Mus spretus) have higher lysosomal activity and less cellular senescence than cells from lab mice, suggesting that wild species may offer natural blueprints for treating age-related lysosomal …
This commentary questions whether JST-IC trajectory patterns genuinely reflect aging decline or instead capture stable life-course abilities shaped by education, technology familiarity, and generational factors. The authors argue researchers need to reconsider how to interpret …
Researchers discovered that tiny nanoparticles embedded in tissue scaffolds can enter immune cell precursors in bone marrow and reprogram their genes to reduce inflammation—and these effects persist even after the cells fully mature. This suggests …
This review examines how CXC chemokines—signaling proteins released by aging cells—contribute to age-related diseases and cancer. The authors propose these molecules could become biomarkers for aging and targets for new longevity therapies, though most evidence …
This review highlights how T cells in the brain show signs of exhaustion as we age, and describes a promising engineered immune protein that could restore brain immune function by rebalancing inflammatory signals. The work …
Researchers discovered that IL-2 signaling in B cells activates a regulatory program that produces anti-inflammatory IL-10, especially in aging B cells. In a mouse model of multiple sclerosis, this pathway was protective—loss of IL-2 signaling …
Researchers mapped five key energy-producing pathways across the human brain using genetic data, finding they're distributed differently in sensory areas and follow distinct aging patterns—peaking in childhood for energy production, but declining throughout life for …
