As people live longer, maintaining mental well-being has become an increasingly important part of healthy aging. While regular physical activity is known to support both physical and psychological health, many older adults face barriers that make traditional exercise programs difficult to sustain. Researchers have therefore been exploring new approaches that combine physical activity with enjoyment, social interaction, and cognitive engagement.

A review published in Volume 18 of Aging titled “What are the effects of exergames on the mood states of older people? A systematic review of experimental studies, impacts on mental health and recommendations,” examined whether exergames—video games that require physical movement to play—can improve mood and mental health in older adults. The study was led by authors from the Laboratory of Sport and Exercise Psychology, Human Movement Sciences Graduate Program, College of Health and Sport Science of the Santa Catarina State University (UDESC) in Florianópolis, Brazil.

BUFFALO, NY — June 18, 2026 — A new #research paper was #published in Volume 18 of Aging on May 26, 2026, titled “Early-life determinants of cardiometabolic outcomes and accelerated biological ageing in Colombia.”

The study was led by first and corresponding author Juan Carlos Rivillas from the Department of Epidemiology and Biostatistics, MRC Centre for Environment and Health, School of Public Health, Imperial College London, United Kingdom.

Experiences during childhood can shape health for decades. Adverse childhood experiences (ACEs), such as emotional abuse, domestic violence, food insecurity, poor health, and forced displacement, have long been linked to chronic disease. However, less is known about how these early-life hardships may influence biological aging itself. In this study, researchers examined whether childhood adversity is associated with cardiometabolic disease and accelerated biological aging among older adults in Colombia.

The investigators analyzed data from 3,385 adults aged 60 years and older who participated in the nationally representative SABE-Colombia study. Five forms of childhood adversity experienced before age 15 were evaluated: emotional abuse, domestic violence, poor childhood health, food scarcity, and forced migration related to Colombia’s armed conflict. Biological aging was estimated using the Klemera-Doubal Method for Biological Age, a biomarker-based measure that compares biological age with chronological age.

BUFFALO, NY — June 16, 2026 — A new #research paper was #published in Volume 18 of Aging on May 22, 2026, titled “Systemic cancer risk profile in neovascular age-related macular degeneration: insights into shared aging-related mechanisms from a nationwide population-based study.”

The study was led by first author Hyeong Min Kim and corresponding author Hyewon Chung from Konkuk University College of Medicine and Konkuk University Medical Center in Seoul, Republic of Korea.

Neovascular age-related macular degeneration (nAMD) is one of the leading causes of severe vision loss in older adults. Although the disease primarily affects the retina, researchers increasingly recognize that it may reflect broader biological processes associated with aging, including chronic inflammation, vascular dysfunction, and immune dysregulation. These same mechanisms have also been implicated in the development of several cancers, raising questions about whether the two conditions may be biologically connected.

To explore this possibility, investigators analyzed data from the Korean National Health Insurance Service, one of the world’s largest population-based healthcare databases. The study included 334,091 individuals aged 50 years and older, including 83,742 patients with nAMD and 250,349 matched controls without the disease. Participants were followed for up to 10 years, allowing researchers to evaluate both overall cancer incidence and risks for specific cancer types.

The analysis revealed that individuals with nAMD had a modest but statistically significant increase in overall cancer risk compared with matched controls. However, the increased risk was not observed across all cancers. Instead, patients with nAMD showed elevated risks for several specific malignancies, including thyroid, kidney, pancreatic, lung, bladder, and prostate cancers, while no significant associations were found for many other cancer types.

BUFFALO, NY — June 11, 2026 — A new #meetingreport was #published in Volume 18 of Aging on May 14, 2026, titled “Foundations of Gerophysics.”

The report was led by corresponding authors Maximilian Unfried and Brian K. Kennedy from the National University of Singapore.

Aging is often studied through biology, genetics, and medicine. Yet despite tremendous advances, many fundamental questions remain unanswered: Why do organisms age at different rates? Why does resilience decline over time? And can the trajectory of aging be predicted before disease develops? Researchers participating in the inaugural Global Conference on Gerophysics explored whether answering these questions may require integrating biology with the quantitative principles of physics.

Held in Singapore on March 5–6, 2025, the conference brought together 160 researchers from physics, biology, computation, and medicine and featured 31 speakers from institutions around the world. The meeting focused on developing a predictive and testable science of aging by applying concepts from dynamical systems, thermodynamics, network theory, stochastic processes, and artificial intelligence to biological aging.

BUFFALO, NY — June 10, 2026 — A new #research paper was #published in Volume 18 of Aging on May 18, 2026, titled “Transcriptional programs diverge in aging mouse and human skeletal muscle.”

The study was led by co-first authors Charles D. Hwang and Siti Rahmayanti and corresponding author Indranil Sinha from Brigham and Women’s Hospital, Harvard University.

Aging is widely associated with the gradual loss of muscle mass, strength, and physical function. Much of what scientists know about these changes comes from studies in laboratory mice, which are frequently used to investigate the biological mechanisms of aging and to identify potential therapeutic targets. However, an important question remains: how closely do aging-related changes in mouse muscle reflect what actually occurs in humans?

To address this question, researchers performed a detailed comparison of gene expression patterns in skeletal muscle from young and old mice and humans. The team analyzed RNA sequencing data from mouse gastrocnemius muscle and compared it with transcriptomic data from healthy young and older adults obtained through the National Institute on Aging’s GESTALT study.

The results revealed substantial differences between the two species. Despite both mice and humans experiencing age-related muscle decline, fewer than 5% of significantly altered biological pathways were shared between them. Many of the genetic programs that changed with aging in mice showed little resemblance to those observed in human skeletal muscle.

Why do some people appear to age faster than others, even when they are the same age? Researchers increasingly believe that chronological age tells only part of the story. Biological age attempts to capture how well the body’s systems are functioning and may provide a more meaningful picture of overall health.

A research paper on this topic was published in Volume 18 of Aging titled “Blood biochemical and gut microbiotic neural network models forecasting human biological age.” In the study, Russian researchers explored whether information from routine blood tests and the gut microbiome could be used to estimate biological age.

BUFFALO, NY — June 5, 2026 — A new #review was #published in Volume 18 of Aging on May 15, 2026, titled “Blue period – features of senescence 30 years after beta-galactosidase.”

The review was led by first author Chisaka Kuehnemann and corresponding author Christopher D. Wiley from Tufts University.

Cellular senescence has emerged as one of the most important biological processes linked to aging and age-related disease. Senescent cells stop dividing in response to stress or damage, yet they remain metabolically active and release a variety of signaling molecules that can influence surrounding tissues. Over the past three decades, evidence has increasingly shown that the accumulation of these cells contributes to chronic inflammation, tissue dysfunction, and many degenerative conditions associated with aging.

In this review, the authors examine how the field has evolved since the landmark discovery of senescence-associated beta-galactosidase (SA-β-gal) in 1995. That finding provided one of the first practical methods for identifying senescent cells and helped establish that these cells accumulate in aging tissues. Since then, researchers have identified numerous additional characteristics of senescence and developed new approaches to study their role in health and disease.

The review highlights several major features now recognized as hallmarks of senescent cells. These include stable proliferative arrest, increased lysosomal activity, secretion of inflammatory and signaling molecules collectively known as the senescence-associated secretory phenotype (SASP), mitochondrial dysfunction, alterations in nuclear architecture, accumulation of metals and lipofuscin, and enhanced survival despite exposure to cellular stress.

BUFFALO, NY — June 3, 2026 — A new #research paper was #published in Volume 18 of Aging-US on May 15, 2026, titled “Extracellular vesicles released by senescent myoblasts affect recipient cells via miRNA-target interactions.”

The study was led by first author Michael Kamal from the Department of Kinesiology at McMaster University and corresponding author Gianni Parise from the same university.

As people age, skeletal muscle gradually loses strength, size, and regenerative capacity. Scientists have increasingly linked these changes to cellular senescence—a state in which damaged cells permanently stop dividing but remain metabolically active. These senescent cells release a complex mixture of signaling molecules known as the senescence-associated secretory phenotype (SASP), which can influence neighboring cells and contribute to tissue dysfunction.

In this study, the researchers investigated whether extracellular vesicles (EVs)—tiny membrane-bound particles released by cells—play a role in this process. Specifically, they examined EVs released by senescent muscle precursor cells, known as myoblasts, and analyzed the microRNAs (miRNAs) carried within these vesicles.

The team found that senescent myoblasts released factors that impaired normal muscle cell development. When healthy muscle cells were exposed to signals from senescent cells, the resulting muscle fibers became significantly smaller and displayed increased expression of genes associated with cellular stress and senescence.

Further analysis revealed that EVs released by senescent myoblasts carried a distinct set of miRNAs. The researchers identified 22 significantly altered miRNAs, including several previously linked to cellular senescence, such as miR-34a, miR-34b, miR-34c, and miR-22. The study also identified miR-301a-3p as a potentially novel senescence-associated miRNA.

BUFFALO, NY — May 27, 2026 — A new #research paper was #published in Volume 18 of Aging-US on May 8, 2026, titled “The mediating role of DNA methylation clocks in associations of race, ethnicity, education, income, and occupation with mortality: findings from NHANES 1999-2002.”

The study was led by first and corresponding author Hanyang Shen from the Department of Epidemiology and Population Health at Stanford University. In this study, the authors investigated whether DNA methylation aging biomarkers—often called epigenetic aging clocks—may help explain how social inequalities become biologically embedded and contribute to differences in mortality risk. Social factors such as race, ethnicity, educational attainment, household income, and occupation have long been associated with disparities in health outcomes and life expectancy. However, the biological mechanisms linking these social exposures to long-term disease risk and mortality remain incompletely understood.

Using nationally representative data from 2,402 adults in the U.S. National Health and Nutrition Examination Survey (NHANES) 1999–2002 linked to mortality follow-up data through 2019, the researchers examined thirteen different DNA methylation biomarkers alongside traditional clinical and behavioral risk factors. The study evaluated whether these epigenetic aging measures mediated associations between social stratification factors and all-cause mortality.

The findings showed that several DNA methylation clocks significantly mediated the relationship between social disadvantage and mortality risk. Among all biomarkers examined, GrimAge2 consistently demonstrated the strongest mediation effects, accounting for up to 52% of mortality disparities in some occupational comparisons. DunedinPoAm, a pace-of-aging biomarker, also demonstrated substantial mediation effects across multiple socioeconomic categories.

Importantly, the mediation effects observed for several DNA methylation biomarkers frequently exceeded those of traditional clinical risk factors measured in the study, including C-reactive protein and cholesterol-related markers. The results suggest that epigenetic aging measures may capture the cumulative biological effects of multiple social, environmental, behavioral, and physiological stressors simultaneously.

“Among all the 13 DNA methylation biomarkers available in NHANES, GrimAge2 consistently exhibited the strongest positive mediation capturing the social disparities on mortality up to 52% (95%CI: 26%-128%), followed by the DunedinPoAm.”
