    Small Extracellular Vesicles Found to Spread Cellular Senescence in Models of Aging

    BUFFALO, NY — October 29, 2026 — A new #research paper was #published in Volume 18 of Aging on October 8, 2026, titled “Small extracellular vesicles as mediators of paracrine senescence in cellular models of aging.” The study found that small extracellular vesicles (sEVs) released by senescent cells can transmit signals that promote senescence in neighboring cells. Using human cellular models of aging, the researchers demonstrated that these membrane-enclosed particles could trigger cell-cycle arrest and DNA damage responses without activating the classical inflammatory pathways associated with senescence. The findings reveal another mechanism through which aging cells may influence their surroundings. The research was led by equal-contributing first authors Aina M. Llabrés-Mas, Antonio Merino-Navarro and Marta Menéndez-García, all affiliated with the Spanish National Research Council (CSIC), Madrid, Spain. Corresponding author Ana O’Loghlen is affiliated with the same institution. Cellular senescence is a process in which cells enter a stable state of growth arrest in response to stress, damage or other signals. Although senescence can help prevent uncontrolled cell proliferation and support tissue repair, the accumulation of senescent cells is associated with aging, chronic inflammation and age-related diseases. Senescent cells can influence surrounding tissues through the senescence-associated secretory phenotype (SASP), which includes inflammatory molecules, growth factors and other signaling substances. These signals can sometimes induce paracrine senescence, a process in which senescent cells promote senescence in nearby, previously proliferating cells. However, not all senescent cells produce the same inflammatory signals. Cells expressing high levels of p16INK4A, a protein involved in regulating cell-cycle progression, can enter a stable growth-arrested state without developing the classical inflammatory SASP. This raises questions about how these cells communicate with their surroundings and potentially influence tissue aging. To investigate this, the researchers examined small extracellular vesicles, membrane-bound particles that transport proteins, nucleic acids and lipids between cells. These vesicles act as biological messengers, transferring molecular information that can influence the behavior of recipient cells.

    Body Composition, Rather Than Masculine Physical Traits, Linked to Aging Markers in Middle-Aged Men

    BUFFALO, NY — October 28, 2026 — A new #research paper was #published in Volume 18 of Aging on October 6, 2026, titled “Body composition, but not morphological masculinity, is associated with biological aging markers in middle-aged men.” The study found that masculine physical characteristics were not independently associated with biological aging markers in middle-aged men. Instead, body composition, particularly fat-free mass percentage and body fat distribution, showed stronger relationships with inflammation and growth hormone levels. However, these associations disappeared after adjusting for adiposity, suggesting that body fat may help explain the observed relationships. The research was led by first and corresponding author Agnieszka Żelaźniewicz, affiliated with the University of Wroclaw. Aging involves changes in hormonal regulation, immune function, metabolism and body composition. In men, testosterone influences the development of masculine physical characteristics, muscle mass and reproductive function. However, its relationship with biological aging remains unclear, with evidence suggesting both potentially beneficial and harmful effects depending on physiological conditions. Some evolutionary theories propose that greater investment in reproductive characteristics may come at the expense of long-term bodily maintenance. According to the limited soma hypothesis, resources devoted to reproductive competition could reduce those available for cellular repair and maintenance, potentially accelerating aging. Traits such as broad shoulders, muscularity, facial proportions and physical strength are influenced to varying degrees by androgen signaling. If developing and maintaining these characteristics carries long-term physiological costs, men with more pronounced masculine traits might be expected to show signs of accelerated biological aging.

    Progerin Expression Creates a Yeast Model of Premature Aging

    Aging is shaped not only by changes in DNA and metabolism but also by the gradual accumulation of proteins that cells struggle to remove. One striking example is Progerin, an abnormal form of lamin A that accumulates at the nuclear periphery in Hutchinson-Gilford Progeria Syndrome, or HGPS. A new study shows that expressing this human protein in budding yeast reproduces several aging-related cellular defects and creates a simple experimental system for studying how toxic proteins accumulate and affect lifespan. A research paper published in Volume 18 of Aging titled “Modeling premature aging in yeast via the expression of Progerin,” developed a yeast model in which human Progerin and its normal counterpart, lamin A, were expressed as fluorescent fusion proteins. The study was led by first author Zachery R. Belak of the University of Saskatchewan, with corresponding author Troy AA. Harkness, affiliated with the University of Saskatchewan and the University of Alberta. The researchers found that Progerin localized to the yeast nuclear membrane, slowed cellular growth, shortened chronological lifespan, increased genomic instability, and was preferentially retained in older mother cells. Together, these findings suggest that yeast can reproduce several cellular consequences associated with Progerin accumulation despite lacking the conventional nuclear lamina found in human cells.

    Hypomagnetic Fields Extend Survival but Reduce Mobility in Fly Model of Parkinson’s Disease

    BUFFALO, NY — October 22, 2026 — A new #research paper was #published in Volume 18 of Aging on September 23, 2026, titled “Hypomagnetic fields modulate lifespan, physical ability and mitochondrial metabolism in a Pink1 model of neurodegeneration.” The study found that exposure to extremely weak magnetic fields increased survival in a fruit fly model of Parkinson’s disease while unexpectedly worsening movement ability. The researchers also identified changes in mitochondrial metabolism and free radical production, suggesting that magnetic field strength may influence aging-related biological processes differently depending on an organism’s genetic background. The research was led by first author Jacob Reed and corresponding author Lisa Chakrabarti, both affiliated with the University of Nottingham. Parkinson’s disease is a progressive neurodegenerative disorder associated with the loss of dopamine-producing neurons, impaired movement and mitochondrial dysfunction. Mitochondria generate much of the energy required for cellular function, and defects in their maintenance can contribute to oxidative stress and neuronal damage. Understanding how environmental conditions influence mitochondrial activity may therefore provide insights into neurodegeneration. The researchers investigated hypomagnetic fields (HMFs), environments in which magnetic field strength is substantially lower than Earth's natural geomagnetic field. Earth's magnetic field typically ranges from 25 to 60 microtesla (μT), while hypomagnetic conditions are generally defined as fields below 5 μT. Although magnetic fields have been studied in relation to animal navigation and cellular metabolism, their influence on neurodegenerative disease remains poorly understood. The study used Drosophila melanogaster, commonly known as the fruit fly, including a genetically modified strain lacking functional Pink1. This gene plays an important role in mitochondrial quality control through the PINK1/Parkin pathway, which helps identify and remove damaged mitochondria. Loss of Pink1 function produces several features resembling early-onset Parkinson’s disease, including impaired movement, mitochondrial dysfunction and reduced lifespan.

    mTOR Signaling Emerges as a Key Regulator of Aging, Highlighting Need for Targeted Interventions

    BUFFALO, NY — October 20, 2026 — A new #review was #published in Volume 18 of Aging on September 19, 2026, titled “mTOR signaling in aging: from causality to geroprotective interventions and hallmark-level outcomes.” The review examines how the mechanistic target of rapamycin (mTOR) signaling pathway influences aging, longevity and age-related diseases. Drawing on evidence from molecular research, animal experiments and human studies, it highlights mTOR as a central regulator of cellular metabolism, stress adaptation and tissue maintenance. The evidence reviewed suggests that carefully controlled modulation of mTOR signaling could support future strategies for healthy aging, although its long-term benefits in humans remain unproven. The review was authored by Natalia Bobok, Chief Scientific Officer at INSTYTUTUM AG, Zug, Switzerland. Aging involves interconnected biological changes, including mitochondrial dysfunction, cellular senescence, impaired protein maintenance and declining regenerative capacity. The mTOR pathway helps coordinate many of these processes by responding to nutrient availability, growth factors and cellular stress. However, while excessive mTOR activity has been associated with age-related dysfunction, completely suppressing the pathway may interfere with essential functions such as tissue repair, metabolism and immune regulation. The review synthesizes evidence from 265 publications and organizes the findings into three major areas: the biological role of mTOR in aging, interventions that influence its activity, and its interactions with the hallmarks of aging and age-related diseases. This framework emphasizes that mTOR operates as a dynamic signaling network rather than a single molecular switch.
