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.

Computational model predicts telomere length from biopsy images

A new computational tool infers changes occurring at the ends of the chromosomes housing our DNA. It does so by detecting structural alterations in cells and tissues captured in images taken of routine medical biopsies, according to findings published March 16, 2026, in Cell Reports Methods.

Higher tyrosine levels linked to shorter lifespan in major UK Biobank analysis

Researchers analyzed over 272,000 UK Biobank participants and used Mendelian randomization to investigate whether circulating phenylalanine and tyrosine influence lifespan. Genetically predicted higher tyrosine levels were linked to shorter lifespan, particularly in men, while phenylalanine showed no independent effect after adjustment.

Early-life telomere length tied to seabird survival

A new study published in Ecological and Evolutionary Physiology reveals a surprising link between cellular aging markers and survival in black-legged kittiwakes (members of the gull family).

Why lung cancer in never smokers is rising and how targeted detection could reduce deaths

Lung cancer in never smokers is an increasingly recognized global health issue with distinct biological drivers, environmental risk factors, and genetic susceptibilities. Improved risk modelling, targeted screening strategies, and preventive approaches are needed to enable earlier detection and reduce mortality in this growing patient group.

Study examines the relationship between leukocyte telomere length and age-related cataract

Cataracts remain the leading cause of blindness worldwide among adults over 50, despite major advances in surgical treatment.

Study reveals DNA methylation score that better detects alcohol intake than standard biomarkers

A Mediterranean cohort study evaluated a DNA methylation biomarker of alcohol intake and compared it with conventional indicators such as GGT. The epigenomic score correlated with alcohol exposure, linked to telomere shortening and epigenetic aging markers, but findings remain observational and population-specific.

AI analysis maps a century of global aging research

A new research paper was published in Volume 17, Issue 11 of Aging-US on November 25, 2025, titled "A natural language processing–driven map of the aging research landscape."

New analysis reveals fundamental flaws in widely used measures of biological aging

A landmark review published today in Genomic Psychiatry challenges researchers to fundamentally reconsider how the field measures and conceptualizes biological aging.

Study reveals ATM kinase as the key driver of replicative senescence

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres-the protective caps at the chromosome ends-those caps eventually become too short to prevent chromosome ends from being recognized as DNA breaks.

Drinking three to four cups of coffee a day may slow cellular aging

New findings reveal that 3-4 cups of coffee daily may enhance telomere length, potentially slowing cellular aging in individuals with severe mental disorders.

Moderate coffee intake linked to slower biological aging in people with severe mental illness

Drinking a maximum of 3-4 cups of coffee a day may slow the 'biological' ageing of people with severe mental illness, by lengthening their telomeres-indicators of cellular ageing-and giving them the equivalent of 5 extra biological years, compared with non-coffee drinkers, finds research published in the open access journal BMJ Mental Health.

Whole genome sequencing reveals how much human heritability we can finally explain

Whole genome sequencing in nearly 500,000 UK Biobank participants shows that observed rare and common variants now explain about 88% of family based heritability for many human traits. By partitioning heritability into rare versus common and coding versus non-coding components, the study narrows where missing heritability still hides and highlights traits that remain only partly understood.

Dysfunction in chromosome-stabilizing protein identified as a cause of deadly illnesses

New research from the University of Wisconsin–Madison reveals that dysfunction in a protein essential to maintaining stability in our chromosomes may be responsible for serious - and sometimes deadly - diseases.

Bowhead whale’s secret to long life revealed: precision DNA repair may hold clues for human aging

Researchers discovered that bowhead whales achieve extraordinary longevity and cancer resistance through highly efficient and precise DNA repair mechanisms. A whale-specific protein, CIRBP, enhances genome stability even in human cells, revealing a potential pathway to strengthen DNA repair and slow aging.

TRF1 protein depletion linked to leaner mice and altered metabolism

A new research paper was published in Volume 17, Issue 9 of Aging-US on September 17, 2025, titled "Depletion of the TRF1 telomere-binding protein leads to leaner mice with altered metabolic profiles."

New research aims to develop targeted therapy for hard-to-treat osteosarcoma

For children and young adults diagnosed with osteosarcoma, a common type of bone cancer for that age group, the odds of survival can be devastatingly low (20-30%) when the disease spreads to the lungs.

Working with service dogs may help slow biological aging in female veterans

New research finds that "man's best friend" may help slow biological aging in women. This groundbreaking study, focused on female veterans in the United States, is among the first to examine the impact of working with service dogs on this often-overlooked population.

Study explains how genetics and lifestyle combined to keep a 117-year-old healthy

Scientists conducted a multiomics study of the world’s oldest verified person (117 years), uncovering protective genetic, immune, metabolic, microbiome, and epigenetic traits that supported her exceptional longevity. These findings highlight how aging and disease may, under rare circumstances, be decoupled.

Study shows dementia patients exposed to pollution had longer telomeres

Researchers studying a Swedish aging cohort found no overall link between air pollution and telomere shortening, a key marker of biological aging. Intriguingly, dementia patients exposed to higher pollution showed longer telomeres, though results were statistically non-significant.
