Telomere

A telomere is a region of repetitive DNA at the end of a chromosome, which protects the end of the chromosome from deterioration.

What are Telomeres?

Telomeres are crucial parts of the chromosome that act to protect them and ensure DNA replication is performed effectively.

AI-based "tissue clocks" measure the biological age of human organs

AI-based "tissue clocks" can estimate the biological age of human organs from histological images, researchers at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and the Ludwig Boltzmann Institute for Network Medicine (LBI-NetMed) at the University of Vienna showed.

New human genome benchmark captures both parental copies with near-perfect accuracy

Researchers created T2T-HG002, a near-perfect diploid human genome benchmark that is free of detectable errors across 99.4% of the genome and captures both maternal and paternal haplotypes. The benchmark expands coverage into previously excluded genomic regions and provides a new framework for evaluating sequencing reads, assemblies, phased variants, and personalized genome inference.

Nighttime light linked to conflicting signs of biological aging

Higher residential nighttime light exposure was associated with contrasting biological aging patterns in nearly 300,000 UK Biobank participants, depending on the aging algorithm used. PhenoAge and homeostatic dysregulation suggested a potentially adverse aging pattern, while KDM-BA showed the opposite association, underscoring uncertainty about how nighttime light relates to biological aging.

New review links obesity with accelerated biological aging mechanisms

The global rise in obesity and population aging represents a major public health challenge, with growing evidence suggesting that excess body fat not only increases the risk of chronic disease but may also accelerate the biological aging process.

Risk-adapted frameworks reshape pediatric neuroblastoma care

Neuroblastoma is the most common solid tumor outside the brain in children younger than five years old and accounts for about 15% of pediatric cancer deaths.

Linguistic style in children predicts future mental health problems

Linguistic models that analyzed the words children used when talking about stressful events proved better at predicting future mental health problems than a panel of human experts.

Spermidine boosts key cellular processes linked to aging in early research

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while observational studies link higher dietary intake to lower mortality. However, human trials have produced limited and mixed results, leaving its clinical role in healthy aging unresolved.

Five epigenetic clocks reveal shared and distinct signals of aging

Researchers linked five epigenetic clocks to distinct blood gene-expression patterns and biological pathways in 3,227 Health and Retirement Study participants. TAGS derived from these patterns often showed stronger associations with frailty, functional measures, morbidity, and mortality than their parent clocks, although further validation is needed.

Filtered coffee links to slower biological aging while instant coffee shows the opposite

Filtered coffee consumption was associated with slower biological aging, while instant coffee was linked to faster aging in UK Biobank participants. The cross-sectional findings do not prove causation, but they suggest that brewing method may influence coffee’s relationship with aging biomarkers.

New method helps scientists better understand DNA organization

Researchers from the Cancer Science Institute of Singapore (CSI Singapore) at NUS have developed a new method that allows scientists to better understand how DNA is organized and regulated inside our cells.

New testing approach improves pulmonary fibrosis diagnosis and treatment

A new Mayo Clinic study shows that integrating telomere length evaluation and genetic testing into pulmonary care can significantly change how physicians diagnose and treat pulmonary fibrosis - in some cases even redirecting the course of care.

Faster biological aging may help explain rising cancer rates in younger adults

A new study found that later birth cohorts showed greater biological aging, measured by systemic age-gap clocks. Greater biological aging was associated with higher early-onset solid cancer risk, especially lung, gastrointestinal, and uterine cancers.

Faster biological aging may explain rising early-onset cancers

The link between biological aging and early-onset cancer risk offers crucial insights into generational health trends and potential preventive measures.

Aging immune cells may explain why autoimmunity rises later in life

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

First human trial targets aging immune cells for healthier immunity

A first-in-human clinical trial of an immune rejuvenation therapy designed to restore the function of worn-out T cells is expected to begin later this year, building on research led by UCL scientists into the mechanisms of immune aging.

Hidden junk DNA could play decisive role in cancer

Many repetitive regions of the genome have been considered "junk DNA" because the technologies available did not allow them to be studied at sufficient resolution.

Mesenchymal drift may explain how aging cells lose their identity

Mesenchymal drift may help explain how cells lose stable identity and acquire pro-fibrotic, inflammatory mesenchymal traits during aging. The review proposes MD as a unifying framework that links multiple hallmarks of aging and highlights partial reprogramming as a potential, but still preclinical, way to counteract this process.

Long telomeres linked to higher lymphoma risk in families

Researchers at the Johns Hopkins Kimmel Cancer Center and the Telomere Clinic at Johns Hopkins have identified a genetic syndrome in which unusually long telomeres - the protective caps at the ends of chromosomes - allow immune cells to remain biologically "younger" for longer than normal, predisposing affected individuals to lymphoma and other cancers.
