Aging clocks and measurement tools
Ageing and interventions modulate health and mortality1, yet the underlying molecular mechanisms of this modulation remain unclear. Here we integrate more than 11,000 transcriptomes from more than 25 tissues across 4 mammals (mouse, rat, macaque …
Ambient temperature is a primordial determinant of longevity across the animal kingdom, yet the molecular transducers that couple thermal cues to aging rates remain elusive. Here, we interrogate the transcriptomic and metabolomic landscapes of Drosophila …
Researchers conducted an intensive year-long self-study (N=1) combining time-restricted eating, exercise, Mediterranean diet, and continuous biomarker monitoring to assess how well a healthy person's body adapts to stress. The study demonstrates new methods for tracking …
The increasing demand for natural food preservatives has intensified research into indigenous microorganisms with biopreservative properties. This study investigated the antimicrobial efficacy and biopreservative potential of lactic acid bacteria (LAB) isolated from traditionally fermented Dacryodes …
ABSTRACT: Gestational diabetes mellitus (GDM) is a rapidly increasing global health challenge that is closely linked to the rising rates of obesity and type 2 diabetes mellitus. Similarly, metabolic dysfunction-associated steatotic liver disease (MASLD) has …
Anthropogenic environmental change imposes severe physiological challenges on wild populations, often leading to accelerated cellular aging. In many vertebrate models, the 'conventional expectation' is that chronic exposure to stressors triggers oxidative damage and increases turnover, …
Cellular senescence is a context-dependent cellular state characterised by persistent cell-cycle arrest, epigenetic remodelling, metabolic reprogramming and acquisition of a senescence-associated secretory phenotype. Transient senescence contributes to embryogenesis, tissue repair and tumour suppression, whereas persistent …
This editorial reviews how small noncoding RNAs—particularly piRNAs—circulating in blood could become better measures of biological age than counting birthdays. The authors argue these molecular markers might eventually replace chronological age in medical decisions, but …
Researchers reviewed how people who live to 100+ maintain surprisingly youthful immune function despite extreme age, resisting the chronic inflammation and immune decline that typically accompany aging. They identified several biological mechanisms—including controlled inflammatory pathways, …
Hydra is a freshwater cnidarian genus that provides a unique comparative model for aging research, contrasting the immortal H. vulgaris with the aging-inducible H. oligactis. Here, we report a high-quality, chromosome-level genome assembly of H. …
BACKGROUND: Little is known about whether epigenetic age acceleration (EAA) clocks are capable of predicting exceptional longevity with or without preserved cognitive function. METHODS: We examined 5844 women from the Women's Health Initiative Memory Study. …
Caloric restriction (CR) extends lifespan and delays age-related diseases in model organisms, yet its effects on biological aging in humans remain unclear. We pooled data from seven randomized CR trials (n = 829) and examined …
Skin aging is a multifactorial, dynamically regulated biological process modulated by the synergistic interplay of intrinsic genetic programming and extrinsic environmental stressors. Chronological skin aging is dominated by molecular signatures such as telomere attrition, mitochondrial …
Human gut Bifidobacteria are abundant during infancy and have been reported to be enriched in some exceptionally long-lived populations, yet whether their beneficial effects on lifespan and healthspan are broadly shared across the genus or …
Researchers analyzed blood chemistry in 213 people over 100 years old and found they have distinctly different metabolic profiles—especially higher bile acids and lower inflammatory markers—compared to younger controls. By identifying these metabolic signatures, they …
A growing body of evidence supports the role of nutrient sensing and metabolism pathways in regulating ageing rate and healthspan, but the diversity of human lifestyles challenges our ability to identify the mechanisms of this …
ALG13 mutations cause congenital disorders of glycosylation and neurodevelopmental deficits, but how asparagine-linked glycosylation 13 (ALG13) deficiency impairs brain development remains unclear. This study aimed to elucidate the underlying mechanisms in Alg13 knockout (ALG13KO) mice. …
AIMS: Following Italy's psychiatric reform, national inpatient numbers declined, but how the age at admission has changed across sex, diagnostic, and admission-type subgroups remains unclear. This study examined 17 consecutive years (2006-2022) of psychiatric admissions …
The management of metastatic castration-resistant prostate cancer (mCRPC) is continuously challenged by the emergence of therapeutic resistance. Under the selective pressure of profound androgen inhibition, a significant proportion of tumors undergo lineage plasticity, evolving into …
Physical exercise is a potent modifier of CNS aging, but its relationship with the cyclin-dependent kinase inhibitor p21 (CDKN1A) is neither uniformly suppressive nor equivalent to cellular senescence. Direct evidence remains sparse and preclinical. Sustained …
