Aging clocks and measurement tools
Chronic atrophic gastritis (CAG) is a critical precancerous condition with limited therapeutic options to halt its progression toward gastric cancer. Targeting dysregulated metabolism and inflammation-driven transformation represents a promising yet underexplored strategy. Herein, through systematic …
Researchers created a miniature laboratory system using human stem cells that reproduces aging hallmarks in just 4 days—a process that normally takes decades. This 'aging-on-a-chip' could accelerate testing of anti-aging therapies and reveal how rejuvenation …
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 …
BACKGROUND: Reproductive aging represents a critical physiological bottleneck characterized by a progressive decline in tissue homeostasis and physiological function. While the gut microbiota is known to shift during host aging, the ecological forces governing the …
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 …
This review synthesizes evidence that natural killer (NK) cells—a type of immune cell—undergo age-related changes that impair their ability to clear damaged cells and regulate inflammation, contributing to aging-related diseases. The authors propose NK cell …
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 …
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. …
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, …
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 …
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 …
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 …
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 …
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, …
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 …
Cellular senescence is a key driver of kidney aging, leading to functional decline and increased susceptibility to chronic kidney disease. While the senolytic combination of dasatinib and quercetin (D + Q) has shown promise in …
Anxiety disorders and posttraumatic stress disorder (PTSD) often occur alongside signs of accelerated biological aging, yet the molecular pathways that connect genetic liability to synaptic and circuit-level dysfunction remain unclear. We performed a multi-gene-set transcriptome-wide …
Researchers tested 16 different biomarkers of aging (epigenetic clocks, blood proteins, telomeres, and others) in over 1,000 people tracked for 7 years. Two markers—Allostatic Load Index and DunedinPACE—stood out as the most reliable predictors of …
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 …
Researchers tested whether dietary changes could shift biological age markers in older adults over 4 weeks. Switching to high-carbohydrate diets or plant-based diets showed improvements in a biological age index, but the authors caution this …
