High tyrosine linked to shorter lifespans in men, large study suggests

A UK Biobank study of more than 270,000 participants found higher blood tyrosine levels linked to shorter life expectancy in men—potentially shaving nearly a year off lifespan—with no clear effect in women. After adjusting for related amino acids and factors, phenylalanine showed no association. Possible explanations include insulin resistance and sex-specific hormone pathways; the study does not test tyrosine supplements directly, but results suggest dietary protein or tyrosine levels could influence aging, warranting further research.

Common high-blood-pressure drug hints at anti-aging potential in animals

Common high-blood-pressure drug hints at anti-aging potential in animals

A long-used hypertension medication, rilmenidine, extended lifespan in the worm C. elegans and induced youthful metabolic changes in mice, pointing to aging pathways that can be slowed with an existing drug. The study links the effect to the nish-1 receptor and autophagy, with older animals benefiting nearly as much as younger ones, and suggests early human trials could focus on biomarkers if safety remains favorable.

Aging science eyes 150-year lifespans

A leading longevity researcher predicts humans could someday live to about 150 years thanks to advances in aging biology and potential rejuvenation interventions, though no timeline is given. He and others have developed aging clocks to measure biological age and assess interventions, with optimism that major breakthroughs could substantially extend healthspan, even if living 1,000 years remains unlikely; experts emphasize that quality of life and independence will shape how such longevity translates to real life.

Genes Hold a Stronger Grip on Lifespan Than Previously Thought

Genes Hold a Stronger Grip on Lifespan Than Previously Thought

A large twin-based analysis from the Weizmann Institute estimates that about 55% of the variation in human lifespan is genetic—far higher than prior 6–25% figures—after separating intrinsic aging from extrinsic death causes and studying twins and siblings raised apart. The finding, published in Science (2026), suggests genetics has a major role in aging and will spur ongoing searches for longevity genes using modern datasets.

Lifespan may be half-genetic, new study suggests

A new analysis published in Science estimates that intrinsic lifespan is about 50% heritable after accounting for extrinsic death causes like accidents and infections, using twin data from Sweden, Denmark, and the U.S. This method contrasts with older estimates (6–25%) and suggests genetics play a larger role than previously thought, though environment and lifestyle remain crucial. The research was limited mainly to Northern European populations, and further work is needed to confirm applicability across diverse groups and to translate findings into aging interventions aimed at extending healthspan.

Genes may set half of your lifespan, new study finds

A Science study published in Science suggests genetics accounts for more than half of the differences in how long people live, meaning our genetic baseline strongly influences lifespan. Environment and lifestyle still matter, potentially shifting a person’s genetically influenced age by about five years through exercise, diet, and social connections. There is no single “longevity gene,” and while maximum human lifespan may hover around 120 years, healthspan and quality of life remain key goals as scientists pursue deeper genetic understanding and potential interventions.

Genes Drive About Half of Human Lifespan, New Study Finds

Genes Drive About Half of Human Lifespan, New Study Finds

A study in Science argues that genetics accounts for roughly 50% of variation in human lifespan after removing the masking effect of extrinsic mortality (accidents, disease, etc.), suggesting genes governing ageing are substantial contributors. Using a math model and twin data from Denmark and Sweden, the researchers found heritability around 50% and noted that as environmental risks declined over the 20th century, genetic influence becomes more evident. The work implies future therapies could target ageing mechanisms, though lifestyle and environment still play a major role, varying by cause of death and age.

Tiny daily tweaks in sleep, diet and exercise may add years to life

Tiny daily tweaks in sleep, diet and exercise may add years to life

A UK Biobank analysis of about 60,000 people found that small daily improvements in sleep (about 5 extra minutes), moderate-to-vigorous exercise (about 2 extra minutes), and eating half a serving more vegetables were linked to longer lifespans. The biggest gains appeared when all three areas improved together: those with an optimal combination—about 40 minutes more exercise per week, 7–8 hours of sleep per night, and a healthy diet—could be predicted to live roughly nine extra years in total and nine extra years in good health versus the bottom performers. However, this is observational and relies on short-term habit measurements, so it shows associations rather than proven causation; wealth and other unmeasured factors could play a role, and more research is needed.

New Research Reveals Optimal Coffee Habits for Longevity and Heart Health

A study suggests that drinking three to four cups of coffee daily may slow biological aging by up to five years, potentially increasing lifespan, due to antioxidants and anti-inflammatory compounds in coffee that preserve telomere length, especially in individuals with severe mental illnesses, though moderation is advised due to possible side effects.
