Can AI outsmart Alzheimer’s? $6.2m grant fund says yes

A $6.2 million NIH grant funds AI-driven analysis of 1,800 Alzheimer's-linked genes to identify genetic targets upstream of amyloid pathology, shifting focus from symptomatic treatment to early-stage vulnerability. Current amyloid-targeting drugs slow progression at best; identifying genetic determinants of susceptibility may enable earlier, more precise intervention before neurodegeneration becomes symptomatic.

Healthy Eating Index, Epigenetic Age Acceleration and Mortality Risk in US Adults

Higher diet quality correlates with slower epigenetic aging and reduced mortality risk in two large U.S. cohorts, with epigenetic age acceleration (GrimAgeEAA) explaining approximately 44% of the diet-mortality association in one cohort. The relationship is partially confounded by physical activity and integrated lifestyle factors, indicating that diet operates within a broader system of behavioral and biological aging pathways rather than in isolation.

A cellular atlas of aging comes into focus

A single-cell chromatin atlas across 21 tissues reveals that aging involves coordinated, sex-specific regulatory remodeling rather than random molecular decay. The coordinated shifts across anatomically distinct organs suggest systemic drivers—circulating signals, immune tone, endocrine cues—offering both mechanistic insight and practical constraints for intervention design.

AI predicts who will decline faster in Alzheimer’s

Machine learning models trained on routine clinic data predict individual rates of cognitive and functional decline in Alzheimer's disease and mild cognitive impairment with greater accuracy than population averages. Early identification of specific functional vulnerabilities—such as difficulty with finances or meal preparation—enables targeted interventions before independence is lost.

Short‐Term Dietary Intervention Alters Physiological Profiles Relevant to Ageing

A 4-week dietary intervention in adults aged 65–75 reduced KDM-derived biological age estimates, with the greatest effects seen in high-carbohydrate and semi-vegetarian groups. This rapid shift in composite biomarkers suggests diet produces measurable physiological changes relevant to aging trajectories, though longer-term data are needed to establish impact on disease risk.

A glycolytic metabolite puts the brakes on cGAS-driven aging

Phosphoenolpyruvate, a glycolytic metabolite, suppresses cGAS-driven inflammation through a direct molecular interaction. The age-related decline in PEP availability explains the transition from metabolic stability to chronic inflammation and neurodegeneration.

HCCaging: a liver physiological aging-related biomarker for hepatocellular carcinoma diagnosis based on transcriptome data

Researchers identified HCCaging, a transcriptome-based biomarker that reflects liver aging patterns and improves hepatocellular carcinoma diagnosis. This tool bridges the gap between cellular aging processes and cancer risk stratification, offering earlier detection potential before advanced disease.

Roche gets CE mark for Alzheimer’s risk blood test

Roche has obtained CE mark approval for a blood test that identifies ApoE4 carriers, a genetic variant associated with increased Alzheimer's risk. This test streamlines risk stratification and treatment planning by enabling clinicians to prioritize patients for further evaluation and guide therapeutic decisions, particularly regarding amyloid-targeting therapies that carry differential risk profiles based on ApoE4 status.

The retina-body axis: proteomic mechanisms linking oculomics and clinical traits in a female aging cohort

Retinal protein signatures correlate with systemic aging markers and clinical traits in women, establishing the eye as a window into whole-body physiological age. These oculometric measures may enable earlier detection of aging-related dysfunction across multiple organ systems.

Sex Differences in Associations Between Adversity and Biological Ageing

Childhood adversity associates with accelerated biological aging markers primarily in women, while adulthood adversity shows stronger associations with aging markers in men. This sex-specific pattern suggests distinct windows of physiological vulnerability across the lifespan that warrant consideration in aging research and clinical intervention timing.

Multimodal data analysis reveals asynchronous aging dynamics across female reproductive organs

Deep learning analysis of histological and transcriptomic data from over 300 female donors reveals that reproductive organs age asynchronously rather than in lockstep, with menopause functioning as a critical inflection point detectable in circulating protein signatures. This challenges the assumption of synchronized aging across organ systems and identifies tissue-specific vulnerability windows relevant to longevity and disease prevention.

Clair Health launches wearable hormone intelligence

Clair Health has launched a non-invasive wearable that uses multimodal biosensors and AI to infer continuous hormonal patterns across the female lifespan, moving beyond episodic blood tests and calendar-based tracking. The device collects skin temperature, heart rate variability, sleep, and breathing data as proxies for endocrine state, positioning hormonal monitoring as a prevention tool rather than a fertility marker.

Association of brain age gap with BMD and incident fractures in the UK Biobank

Accelerated brain aging—measured as the difference between chronological age and brain imaging markers—correlates with lower bone mineral density and increased fracture risk independent of chronological age. This suggests neurobiological aging patterns may predict skeletal fragility and fracture vulnerability in midlife and older adults.
