A summary of the paper mentioned… "In a [widely cited paper](https://pubmed.ncbi.nlm.nih.gov/37117782/) laying out the theory, Cohen and his co-authors argued that “disruption of this ensemble causes… the functional manifestations of ageing.” ## Your Body Is an Ecosystem, and Aging Is Its Slow Unraveling **In this 2022 Nature Aging Perspective, twelve researchers from geriatrics, ecology, physics and molecular biology argue that aging research has to move on from studying single genes and pathways to studying how those parts interact. Drawing on theoretical ecology, they describe the body as a complex system that evolution shaped to hold a dynamic equilibrium. On this view, aging is the gradual failure of that integrated regulation, at every scale from molecules to whole persons. Three concepts anchor the argument. The first is emergence: frailty, delirium and possibly Alzheimer’s disease are outcomes at the level of the whole system. The second is resilience and critical transitions: rising variance and correlation act as early warnings of collapse. The third is networks: “bowtie” structures in which mTOR, AMPK, sirtuins and inflammation pull together many signals. The paper presents no new data. Its practical claim is that single-target interventions will tend to carry hidden trade-offs, which makes multi-modal approaches the better bet.** For three decades, aging research has been a hunt for master switches: find the gene, pathway or molecule, then dial it up or down. That strategy gave us mTOR, AMPK, sirtuins and the hallmarks of aging. A group of twelve researchers led by Alan Cohen at the University of Sherbrooke now argues that the strategy is yielding less and less, and that the field should start treating the body the way ecologists treat a forest or a fishery. The comparison is deliberate. In the 1970s, ecology stopped thinking in food chains and started thinking in food webs. That shift explained why obvious interventions failed. Culling seals to rescue cod stocks, for example, ignored the web of other species connecting the two. The authors see a direct parallel in aging biology. Antioxidant supplements were supposed to slow aging by mopping up free radicals. Free radicals then turned out to be essential signals that the body keeps tightly regulated at intermediate levels. Push on one node and the network pushes back. Their central claim is that aging is less a pile of separate damage processes than the slow failure of an integrated regulatory system. Three ideas carry the argument. The first is emergence. Frailty, falls and delirium have no single cause, yet each appears as a recognizable clinical state. The authors suggest Alzheimer’s disease may belong in the same category. In that reading it arises from many interacting failures across neurons, brain tissue, sleep, physical activity, cardiovascular health and social life, rather than directly from amyloid. The second is resilience. Ecologists studying tipping points have found that systems nearing collapse wobble more, recover more slowly, and develop tighter correlations among their parts. Small human studies fit this pattern. Frail older adults show bigger day-to-day swings in self-rated health. In hemodialysis patients, a rising score of instability across many biomarkers flagged approaching death. The third is network structure. Many inputs, such as nutrients, stress and inflammation, funnel through a few hub pathways like mTOR and AMPK, which then fan out to control many outputs. In this bowtie arrangement, adjusting a hub changes far more than the intended target, and the same intervention can help in one setting and harm in another. The practical lesson runs against much of the longevity industry. If the body is always balancing trade-offs, a molecule that improves one aspect of aging will often cost something elsewhere, or work only under particular conditions. The authors favor multi-modal approaches, especially combinations of lifestyle changes, possibly paired with drugs. They also call for global measures of system state, such as physiological complexity and resilience, to track how well those approaches work. Parts of this view have real evidence behind them. Young hearts beat with a complex, irregular rhythm that flattens with age. Less complex blood pressure and balance signals predict dementia and falls. In small trials, tai chi and vibrating insoles have pushed balance complexity upward. #### Actionable Insights The paper itself gives no dosing or protocols. The studies it cites do point to practical moves. - Train multi-system skills. Tai chi, done three hours a week for 24 weeks, raised a balance-complexity score by about 15% in 25 older adults with nerve damage in the feet. That is a large shift (Cohen’s d about 1.3). There was no control group, so the true effect is probably smaller. [Confidence: Low-Medium] - Take balance seriously. Older adults in the lowest fifth for balance complexity had 48% more falls over four years than those in the highest fifth. Standard balance tests missed this. [Confidence: Medium] - Support your sensory input. Subsensory vibrating insoles cut stride-to-stride variability by 13 to 18% and shaved about 0.3 to 0.4 seconds (3 to 4%) off a standard stand-up-and-walk test in 12 healthy seniors. That is a small, short-term effect. [Confidence: Low] - Protect cardiovascular regulation. People with the least complex beat-to-beat blood pressure had a 55% higher dementia risk over 20 years than those with the most complex. With about 18% of the cohort developing dementia, that works out to very roughly 6 to 8 percentage points of absolute risk over two decades. This is an association, not proof that changing it helps. [Confidence: Low for the absolute estimate] - Combine levers. Exercise, sleep, mood, cardiovascular risk control and social contact all appear in the authors’ dementia model. Track trends in heart rate variability (HRV) or wearable data for rising instability rather than reacting to single readings. #### Context and Source - Full title: [A Complex Systems Approach to Aging Biology](https://pubmed.ncbi.nlm.nih.gov/37117782/) - Lead institution: PRIMUS Research Group, Department of Family Medicine, and the Research Center on Aging, University of Sherbrooke - Country: Canada (lead), with co-authors in the USA (NIA, Harvard/Beth Israel, Yale, Johns Hopkins, UC San Diego, Drexel, Columbia), the Netherlands (Radboud) and Spain (CRG Barcelona) - Journal: Nature Aging, 2022 - Competing interest: The lead author is CEO and founder of [Oken Health](https://www.thecompanycheck.com/company/b/oken/9gpj589klorgn77pg). - Impact evaluation: The impact score of this journal is 25.0 (2025 Journal Impact Factor, released June 2026, up from 19.4), evaluated against a typical high-end range of 0-60+ for top general science journals, therefore this is a **High impact journal.** ---

And another paper mentioned in that article: "In 2024, researchers at the University of Cologne [published](https://pubmed.ncbi.nlm.nih.gov/39227753/) some of the plainest evidence yet for the idea that ageing may be less about individual systems failing, and more about their (in)ability to work together. ## Aging Cells Don’t Get Noisy, They Lose Teamwork **Researchers at the University of Cologne set out to test a long-standing idea: that gene regulation becomes sloppier with age. They built a gene network model trained on more than a thousand cancer cell line transcriptomes. They then used it to score how well each gene’s activity could be predicted from its regulatory neighbors in post-mortem tissue from GTEx donors aged 20 to 79. In eight tissues with detectable age effects, they found no general slide into transcriptional noise. Roughly as many gene relationships strengthened with age as weakened. The weakening links were mostly between different cellular processes. One example is the lysosomal mTORC1-activation machinery separating from mitochondrial electron transport genes in arteries. Strengthening links often sat within a single function, such as coagulation in blood.** A popular picture of aging holds that cells slowly lose control of their genes, like an orchestra drifting out of tune. A new analysis from the University of Cologne suggests the musicians mostly keep playing their own parts well. What breaks down is the coordination between sections. Ana Carolina Leote, Francisco Lopes and Andreas Beyer started with a practical problem. Simply measuring whether two genes rise and fall together cannot tell you why that relationship changes. A pair of genes might stop moving in step because regulation is failing, or because the cell is deliberately responding to something new. To separate the two, the team learned a map of stable gene-to-gene relationships from more than a thousand cancer cell lines, where tissue mixtures and shifting cell types do not muddy the signal. For each gene, the map names a small set of “neighbor” genes whose activity predicts it. They then applied the map to human tissue. Using donated tissue samples from the GTEx project, covering donors from their twenties to their seventies, they asked a simple question: how well do a gene’s neighbors predict its activity in young people compared with older people? They call this score “predictability.” The first surprise was what they did not find. There was no broad decline in predictability with age. Across the eight tissues where aging left a clear mark, roughly as many genes became more predictable as became less predictable. Brain, breast, testis and esophagus leaned toward stronger relationships. Blood, thyroid, artery and fat leaned toward weaker ones. The second finding was about where the weakening happens. Links that faded with age mostly connected genes in different cellular processes. Links that strengthened appeared both within and between processes. The cell’s departments keep working internally but stop talking to each other as well. One example stands out for longevity researchers. In artery tissue, a gene called LAMTOR5 helps dock the growth regulator mTORC1 at the lysosome, the cell’s recycling center, when nutrients are plentiful. In young donors, LAMTOR5 moved in tight step with genes for the lysosome’s acid pump and for mitochondrial energy production. In older donors that coupling largely disappeared. Since mTORC1 normally helps coordinate growth with energy supply, the authors suggest aging cells may lose the ability to mount integrated responses such as growth. Blood showed the opposite pattern. A network of serum proteins tied to clotting and inflammation, including fibrinogen, thrombin and an anti-inflammatory protein called ITIH2, became more tightly coordinated with age. The authors read this as an adaptive response to rising inflammation, consistent with the known increase in clotting tendency in older people. The work also challenges a common assumption about aging biomarkers. Genes that became more variable between people as they aged usually became more predictable, not less. Diverging gene activity in older adults may often reflect regulated responses to different lives rather than random decay. The study has real limits. It is cross-sectional and based on post-mortem bulk tissue, and the single-gene hits rest on uncorrected statistics. It relies on cancer cell lines to define what “normal” coordination looks like. Still, it moves the conversation from “aging is noise” to “aging is miscommunication,” and that is a testable idea. #### Actionable Insights This study tested no intervention, so its practical lessons are indirect. - Aging is mostly not random breakdown. Most gene regulation held steady. The losses were concentrated in links between systems. Approaches that act on many systems at once, like exercise, fit this picture better than single-pathway fixes. [Confidence: Low] - Growth signaling and mitochondria can drift apart. In arteries, the share of LAMTOR5’s activity explained by its neighbors fell from about 55% in people in their twenties to about 5% in their seventies, a 70% drop in predictability. This is one gene in one tissue, with wide uncertainty. [Confidence: Low] - Older blood coordinates clotting more tightly. ITIH2’s predictability rose from about 4% of variation explained to about 59% across the same span. This lines up with the known rise in clotting tendency with age, which supports paying attention to cardiovascular and clotting risk factors over time. [Confidence: Low-Medium] - Read aging biomarkers with care. Rising differences between people often reflected regulated responses, not damage. “Drift” in a single marker is not automatically bad. [Confidence: Medium] - For rapamycin users, nothing here says whether rapamycin restores or worsens this decoupling. That data does not exist yet. #### Context and Source - Full title: [Loss of coordination between basic cellular processes in human aging](https://pubmed.ncbi.nlm.nih.gov/39227753/) - Institution: Cologne Excellence Cluster on Cellular Stress Responses in Age-Associated Diseases (CECAD), Institute for Genetics, and Center for Molecular Medicine Cologne, University of Cologne - Country: Germany - Journal: Nature Aging, 2024 - Impact evaluation: The impact score of this journal is 25.0 (2025 Journal Impact Factor, released June 2026), evaluated against a typical high-end range of 0-60+ for top general science journals, therefore this is a **High impact journal.** ---

Reading this through Miller’s “Seven ways not to think carefully about aging”, the one thing I’m sure of is that this this loss of coordination is not necessarily due to aging, but is part of the process of aging.
