Menopausal Serum Protein Changes May Predict Brain Health: A recent analysis of serum protein changes identified 16 proteins related to inflammatory, synaptic, metabolic, and Alzheimer’s disease processes whose levels change during the menopausal transition.

Making SIRT1 and NAD+ Therapies Work in People: Reviewers publishing in Biology have elucidated SIRT1 functional reserve as an aspect of aging, describing how its depletion is an upstream cause of age-related disorders at the cellular level and explaining why many prospective therapies that increase SIRT1 and NAD+ have not had promising results.

Blocking STING Helps Preserve Bone in Aging Mice: A new study links STING-mediated signals from marrow fat cells to inflammation and declining NAD⁺ levels in bone-forming cells. Interrupting this pathway helped preserve aging bone.

An RNA Regulator Mitigates Senescence in Blood Vessels: Researchers publishing in Aging Cell have found that the regulatory protein MTR4 fights DNA damage in the blood vessel lining but decreases with aging.

AI Extracts Broader Health Insights From Routine CT Scans: A new study suggests that CT scans can provide information about a wide range of conditions, including some not typically diagnosed through imaging.

How Some Neuronal Cilia May Affect the Whole Body: A team of researchers has written a paper with a surprising finding: that many of the benefits of caloric restriction and increased NAD+ may be due to their effects on the cilia of hypothalamic neurons.

Rejuvenation Factor Extends Lifespan and Healthspan in Mice: A recent study identified SRSF1, an RNA-processing and splicing factor, as a molecule with geroprotective potential.

An Astrocytic Factor Slows Whole-Body Aging in Mice: In Aging Cell, researchers have described how increasing fibroblast growth factor 13 (FGF13) in astrocytes reduces aging throughout the bodies of mice.

An Anti-Senescence Vaccine Increases Mouse Lifespan: Late-life treatment with a three-element senolytic vaccine led to lower senescence markers and a 12% increase in median lifespan in female B6 mice.

Midlife time-restricted feeding preserves skeletal muscle insulin responsiveness and function during aging: Midlife time-restricted feeding preserved lean mass, muscle performance, glucose tolerance, and insulin-stimulated glucose uptake in male mice.

Vitamin D Deficiency, Supplementation, and Aging-Related Morbidity and Mortality Across Two Longitudinal Population Cohorts: These findings support severe vitamin D deficiency as an important and potentially modifiable determinant of systemic aging vulnerability and age-related multimorbidity in human populations.

The Effects of Blueberry Consumption on Cerebral Blood Flow and Brain Glutathione Levels in Older Adults: A Double-Blind Randomized, Placebo-Controlled Trial: Compared with placebo, blueberry consumption increased blood flow in the anterior cingulate cortex, a brain region relevant to age-related cognitive decline.

Resistance Training Improves Respiratory Muscle Strength and Immune Response in Older Adults: A Randomized Clinical Trial: The concomitant increase in circulating Klotho suggests that resistance training may promote biological mechanisms associated with healthy aging, supporting its implementation as a non-pharmacological strategy to preserve functional independence and respiratory health in the elderly.

When to Trust Epigenetic Clocks: Avoiding False Positives in Aging Interventions: These findings provide a framework for interpreting epigenetic clock results in anti-aging intervention studies, and suggest that some previously published single-clock findings may warrant reexamination.

Investigating the efficacy and toxicity of partial in vivo reprogramming as a rejuvenation intervention: These findings highlight tissue-specific responses to partial reprogramming and emphasize the need for larger, controlled studies to clarify physiological outcomes and safety.

H3K9me3 inhibition reverses Alzheimer’s progression by restoring synaptic and immune proteostasis across the brain–retina axis: This study identifies H3K9me3 accumulation as a shared, reversible epigenetic contributor to Alzheimer’s disease.

Synergistic reversal of mesenchymal stem cell senescence by engineered exosomal delivery of a dual miR-195/miR-188 sponge: Exosome-mediated delivery of a dual miRNA sponge represents a mechanism-driven strategy to reprogram senescence-associated gene networks and restore MSC function.

Chronic Senolytic Treatment and/or Aerobic Exercise Reduce Senescence and Improve Myocardial Function During Aging in the Heart: These findings demonstrate that long-term exercise or senolytics limit senescence at the cellular level within the myocardium and improve ventricular function.

Aged microenvironment-triggered nanoreactors rejuvenate senescent LepR+ cells to remodel aged bone marrow: Collectively, these findings suggest that the CLPM nanoreactor offers a promising approach for rejuvenation of the aging skeletal system.

Dynamic force sensing by bone delays aging and extends lifespan: This could potentially be manipulated to prevent aging, extend health, and aid those unable to exercise or with decreased mobility.
