Dr. Thomas Seyfried Reveals Cancer as a Metabolic Disease

BUFFALO, NY- October 31, 2024 – A new #research paper was #published as the #cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), Volume 16, Issue 20, entitled, “Longevity biotechnology: bridging AI, biomarkers, geroscience and clinical applications for healthy longevity.”

This paper summarizes recent advances in healthspan biotechnology discussed at the 2023 Aging Research and Drug Discovery Meeting (ARDD), where leading experts reviewed breakthroughs in artificial intelligence (AI), biomarkers, aging clocks, geroscience, and clinical trials that support healthier, longer lives. The authors present a comprehensive view of how these technologies are shaping research and industry approaches to aging, focusing on targeting aging itself to reduce multiple age-related diseases and extend the healthy years of life.

With people living longer, addressing age-related health issues is more critical than ever. Traditional healthcare often treats age-related diseases individually, overlooking aging as a core issue. Longevity biotechnology seeks to change this by combining AI with biomarker analysis to detect early signs of aging, enabling targeted interventions that not only delay disease but also promote longer, healthier lives.

Led by corresponding authors Yu-Xuan Lyu from Southern University of Science and Technology Shenzhen; Alex Zhavoronkov from Insilico Medicine AI Limited, Masdar City, Abu Dhabi; Morten Scheibye-Knudsen and Daniela Bakula from the Center for Healthy Aging, University of Copenhagen, this research synthesizes the potential of AI to identify precise biomarkers of aging, supporting the development of "aging clocks"—tools that use biological data to estimate a person’s biological age and health risks. These tools help clinicians tailor prevention and treatment to individual needs. Additionally, AI speeds up the discovery of drugs that target primary aging drivers, such as cellular damage and decreased cellular energy, offering the potential to slow, prevent, or even reverse certain effects of aging and enhance quality of life.


“The fusion of AI with biomarker research has markedly revolutionized the way biomarkers are identified and validated in the field of ageing.”


This approach not only promises to slow, prevent, or even reverse certain effects of aging but also emphasizes the potential for AI-driven methods to extend healthspans.

In conclusion, the authors emphasize the need for continued investment in AI-driven therapies and biomarker research, which hold the potential to redefine aging care and improve health outcomes as people grow older.

Aging (Aging-US)

Longevity Biotechnology: AI, Biomarkers, Geroscience & Applications for Healthy Aging

BUFFALO, NY- November 6, 2024 – A new #research paper was #published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), Volume 16, Issue 20 on October 24, 2024, entitled “On the lifespan of Enchytraeus crypticus - impact of iron (nanomaterial and salt) on aging.”

This recent study reveals important insights into how iron oxide nanoparticles (Fe3O4 NMs)—tiny particles with unique magnetic properties widely used in medicine and environmental procedures—may affect soil health over time. Led by Susana I.L. Gomes, Janeck J. Scott-Fordsmand, and Mónica J.B. Amorim from the University of Aveiro in Portugal and Aarhus University in Denmark, the research focuses on how these particles interact with the soil-dwelling worm Enchytraeus crypticus, which plays an essential role in breaking down organic matter and supporting soil structure. 

Iron oxide nanoparticles are increasingly used in applications like magnetic resonance imaging, drug delivery, and environmental cleanup. Their effects on soil ecosystems remain largely unexplored. In this study, the team selected Enchytraeus crypticus, a globally present soil-dwelling worm, as an indicator species to assess potential risks to soil health. Over a 202-day period, they examined how iron oxide nanoparticles and traditional iron salt (FeCl3) impact the worm’s lifespan, aging, and reproductive ability.

Findings revealed that prolonged exposure to iron oxide nanoparticles reduced the lifespan, longevity, and reproductive success of Enchytraeus crypticus, particularly in isolated conditions. Worms in lower-density groups experienced greater harm, with shorter lifespans and fewer offspring, while those in larger groups faced less severe impacts. This suggests that population density and environmental factors may influence nanoparticle toxicity. Although iron chloride also showed toxic effects, iron oxide nanoparticles posed higher risks over time, likely due to a slower release of iron ions that extends exposure.

In conclusion, this research highlights the importance of comprehensive studies on the long-term effects of nanoparticles on the environment. As iron oxide nanoparticles become more prevalent, understanding their impact on soil ecosystems is crucial to protecting biodiversity and ensuring the sustainability of natural resources.

Impact of Iron on Aging in Enchytraeus crypticus

Imagine a future where we not only live longer but stay healthy throughout those extra years. Thanks to recent breakthroughs in biotechnology and artificial intelligence (AI) in healthcare, this vision is closer to becoming a reality.

Advancements in Aging Research

Aging research has made significant progress in recent years by combining disciplines like biology, technology, and medicine to tackle the challenges of extending healthspans and reducing age-related diseases. While people today live longer than ever before, extending our “healthspan”—the years we stay active and illness-free—remains challenging. AI and health biomarkers (biological indicators of our body’s condition) are now key tools in the pursuit of longer, healthier lives.

In a recent paper, led by corresponding authors Yu-Xuan Lyu from Southern University of Science and Technology Shenzhen; Alex Zhavoronkov from Insilico Medicine AI Limited, Masdar City, Abu Dhabi; Morten Scheibye-Knudsen and Daniela Bakula from the Center for Healthy Aging, University of Copenhagen, along with numerous other collaborators, the transformative potential of AI in aging research was explored.

Aging’s Ongoing Support for Scientific Innovation: Sponsoring the Muscle Aging Science & Translation Symposium

Sponsoring the Muscle Aging Science & Translation Symposium

In a world where we are living longer but not always healthier, scientists are searching for ways to add life to our years, not just years to our lives. A recent study published in Aging (Aging-US), Volume 17, Issue 4, led by researchers at the National University of Natural Medicine, suggests that certain common foods, already known for their health benefits, might also help slow or even reverse epigenetic or biological aging. These foods, rich in specific plant compounds, appear to influence our DNA in ways that may slow down the body’s epigenetic clock.

Longevity & Aging Series Wins Silver Award for Excellence in Video/Film at SSP EPIC Awards

BUFFALO, NY — July 30, 2025 — A new #research paper was #published in Aging (Aging-US) on July 23, 2025, titled “Second generation DNA methylation age predicts cognitive change in midlife: the moderating role of childhood socioeconomic status.”

In this study, led by Sophie A. Bell and Eric Turkheimer from the University of Virginia, researchers investigated how biological aging, measured through DNA methylation, is connected to changes in thinking skills during midlife and whether childhood socioeconomic status influences this relationship. 

Biological age provides a picture of how the body is aging that goes beyond simply counting years. In this study, researchers used both first- and second-generation DNA methylation clocks—tools that track chemical changes in DNA as markers of aging. GrimAge and PhenoAge, the second-generation clocks designed to reflect broader health and aging processes, were more accurate at predicting long-term changes in Intelligence Quotient (IQ) than the first-generation models that only estimated chronological age. The study analyzed 287 participants from the Louisville Twin Study, which is a long-term project that has followed twins from childhood into midlife.

“DNAmAge was estimated with five commonly used algorithms, or epigenetic clocks (Horvath, Horvath Skin and Blood, GrimAge, and PhenoAge).”

The results showed that twins with more rapid epigenetic aging had a larger drop in IQ scores. This pattern remained even after considering genetic background and early family environment, made possible by the twin-based design. Importantly, the relationship was strongest in twins who had grown up in families with lower socioeconomic status. This finding suggests that early-life disadvantage may make individuals more vulnerable to the effects of biological aging on brain health.

This research adds knowledge to earlier work showing that childhood poverty can influence long-term health. It also highlights the value of second-generation epigenetic clocks as early indicators of brain aging. Unlike the first generation of clocks, these newer tools capture broader biological changes such as inflammation, disease risk, and behaviors like smoking.

Although smoking partly explained the results because it strongly influences DNA methylation, it did not fully account for the association between accelerated biological aging and cognitive decline. This suggests that both life experiences and lifestyle factors shape body and brain aging.

By combining decades of developmental data with a genetically informed twin design, the study provides new evidence that biological aging, especially when shaped by childhood adversity, is a key factor in midlife cognitive decline. These findings may inform early health strategies that consider both social and biological risks and support the use of second-generation methylation clocks to predict age-related cognitive changes.

The Retirement Clinic-8-9-25 – Retirement Savings and Estate Planning

BUFFALO, NY — October 1, 2025 — A new #research paper #featured as the #cover of  Volume 17, Issue 9 of Aging-US was published on August 21, 2025, titled “Sex-specific longitudinal reversal of aging in old frail mice.” 

The study, led by first author Cameron Kato and corresponding author and Aging-US Editorial Board Member Irina M. Conboy from the University of California, Berkeley, reports that a combination of oxytocin and an Alk5 inhibitor (OT+A5i) significantly extended both lifespan and healthspan in frail, elderly, male mice. These rejuvenating effects were not seen in female mice, highlighting key biological differences between the sexes in their response to aging therapies.

The researchers tested a dual-drug approach targeting two biological pathways that change with age. Oxytocin, a hormone that declines with aging and supports tissue repair, was combined with an Alk5 inhibitor that blocks the TGF-beta pathway. TGF-beta becomes overactive with age and contributes to chronic inflammation and tissue damage. In this study, frail mice at 25 months of age—roughly equivalent to 75 human years—were treated regularly with the OT+A5i combination.

Male mice receiving the therapy lived over 70% longer than untreated controls and showed significant improvements in physical endurance, agility, and memory. According to hazard ratio analysis, the treated males were nearly three times less likely to die at any given time than untreated males. 

“Treatment of old frail male mice with OT+A5i resulted in a remarkable 73% life extension from that time, and a 14% increase in the overall median lifespan.”

The therapy also reduced “biological noise” in circulating blood proteins—an established marker of aging—bringing those levels back to a more youthful state. Short-term benefits, were seen in both sexes, however, after four months of continuous treatment, only the male mice showed sustained improvement in systemic protein balance. Female mice did not experience significant gains in lifespan or healthspan, though middle-aged females did show improved fertility after treatment.

These results underscore the importance of understanding sex-specific biology when developing treatments for aging. While the reasons for these differences remain unclear, the findings provide a new model for studying and designing longevity therapies.

Oxytocin is already FDA-approved, and Alk5 inhibitors are currently in clinical trials, suggesting that this approach could be translated to humans. With strong results in aged and frail male animals, OT+A5i appears to be a promising candidate for improving late-life health and survival.

Sex-Specific Effects Found in New Anti-Aging Therapy for Elderly Mice

As life expectancy increases, there is growing interest not only in extending lifespan but also in improving the quality of those additional years. To address the physical and cognitive decline that often accompanies aging, researchers have explored a variety of strategies. Many of these focus on a single biological factor, such as reducing inflammation or stimulating stem cell activity. However, aging is a complex process involving multiple, interconnected changes in the body.

Recognizing this, researchers at the University of California, Berkeley proposed a more comprehensive approach: targeting multiple aging-related pathways simultaneously. Their study, titled “Sex-specific longitudinal reversal of aging in old frail mice,” was recently featured on the cover of Aging-US (Volume 17, Issue 9).

New Anti-Aging Combo Boosts Lifespan in Old Male Mice

BUFFALO, NY — October 3, 2025 — A new #research perspective was #published in Volume 17, Issue 9 of Aging-US on August 26, 2025, titled “Analysis of the current state of frailty indexes and their implementation for aging intervention studies.” 

In this work, led by first author Oliver G. Frost from  Loughborough University alongside corresponding authors Abdelhadi Rebbaa and Amit Sharma,  from the Lifespan Research Institute, the authors explore growing concerns about the lack of standardization in how frailty is measured in rodent aging studies, which may limit the development of effective interventions targeting age-related decline.

Frailty, a key indicator of deteriorating health in older adults, is increasingly assessed in preclinical models using frailty indexes (FIs). These indexes quantify health deficits, such as reduced mobility, cognitive decline, or physical weakness. However, this perspective highlights that FI methodologies vary significantly across studies, from the selection of parameters to the cut-off thresholds used, resulting in inconsistent outcomes that affects reproducibility and translational value.

The authors reviewed 18 rodent studies and found substantial variation in how frailty is defined and measured. Some FIs rely on clinical observations, such as appearance or beahaviour, while others focus on physical performance metrics like grip strength or locomotion. In several cases, applying different FIs to the same group of animals produced contradictory results, underscoring the importance of harmonized protocols.

To illustrate these issues, the researchers applied an 8-item FI to mice of different ages and found that even young mice were sometimes scored as frail, depending on the scoring method and reference values. This finding emphasizes the need for consistent baselines and controlled environments, especially when comparing across studies. The authors recommend using each animal as its own baseline in longitudinal studies, a strategy that enhances reliability without adding significant cost.

“Sex as a biological variable in FIs is an important consideration, as there is a known difference between male and female frailty onset and progression.” 

The authors also discuss emerging automated tools, such as video-based open-field testing, which can reduce observer bias and improve reproducibility. In the future, broader health indicators, such as cognition, circadian rhythms, social behavior, and body composition, may further enhance frailty assessments.

Overall, this work underscores the urgent need for standardized, transparent, and reproducible methods for evaluating frailty in preclinical aging studies. Improved consistency in frailty scoring will better inform the development of healthspan-extending therapies and enhance the translational relevance of animal models.
