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.

NIH grant funds evaluation of expanded Medicare Advantage benefits

Today, more than half of older Americans receive their Medicare coverage through private Medicare Advantage plans. In 2020, that program made a sweeping policy shift, allowing those plans to offer supplemental benefits beyond traditional medical care, including groceries, meal deliveries, utilities, transportation, pest control, and air filters.

Scientists discover how muscle stem cells "flip a switch" to rebuild damaged muscle

Scientists at the University of California, Irvine's School of Pharmacy & Pharmaceutical Sciences have discovered how muscle stem cells "flip a switch" to rebuild damaged muscle – a finding that could help address muscle loss linked to aging, injury and widely used weight-loss medications.

Mendelian randomization study reveals opposing roles for IL6 and IL6R in long-term mortality

A new research paper was published in Volume 18 of Aging-US on February 6, 2026, titled "Causal effects of inflammation on long-term mortality: a Mendelian randomization study."

Can peanut butter improve mobility after 65?

Research indicates that peanut butter can enhance muscle power in older adults, but its impact on overall physical function and gait speed is limited.

Building an affordable toolkit for healthy aging

As people age, they experience a gradual decline in intrinsic capacity (IC), the combined physical and mental abilities that support independence and health. The World Health Organization recognizes IC as a central indicator of resilience in aging, yet no affordable, validated tool exists to measure it.

Misdiagnosed Parkinson's patient regains life after NPH treatment

At age 66, Richard "Dick" Nash first suspected something might be wrong when he participated in a Dallas walk for juvenile diabetes in honor of his granddaughter.

Smoking triggers epigenetic damage linked to macular degeneration

Through a series of experiments supported by the National Institutes of Health, Johns Hopkins Medicine (JHM) researchers say they have advanced understanding of how smoking damages the eye and contributes to the development of age-related macular degeneration (AMD), the leading worldwide cause of visual impairment and blindness among people 50 and older.

Researchers reveal why SuperAgers retain youthful brain cell signatures into their 80s

Researchers used single-nucleus RNA sequencing and chromatin accessibility profiling to map human hippocampal neurogenesis across adulthood, aging, and Alzheimer’s disease. They found that chromatin accessibility changes, more than gene expression alone, distinguish healthy aging, preclinical pathology, Alzheimer’s disease, and cognitive resilience in SuperAgers.

New Mandarin cognitive tests improve dementia diagnosis for Chinese older adults

Asian Americans are the fastest-growing group of older adults in the U.S., but they often face language and cultural barriers when seeking care for dementia-related symptoms.

Middle-aged men most vulnerable to aging effects of new PFAS

Per- and polyfluoroalkyl substances (PFAS) – 'forever chemicals' in common parlance – are a class of thousands of synthetic chemicals often used in non-stick coatings, water-resistant fabrics, fire-fighting foams, food packages, cleaning products, and plastics.

New single pill regimen simplifies treatment for resistant HIV

A phase 3 clinical trial, led by Professor Chloe Orkin of Queen Mary University of London, has shown that a new, daily oral tablet that combines two current HIV treatment medications – bictegravir and lenacapavir (BIC/LEN) – may simplify treatment significantly for people with HIV who currently take very complex treatments.

Having “hasslers” in your network linked to faster aging and poorer health

Researchers analyzed a state-representative US sample to examine whether negative social ties, termed “hasslers,” are associated with epigenetic age acceleration and faster biological aging. Each additional hassler was linked to roughly nine months higher biological age and a 1.5% faster pace of aging, with particularly strong associations for mental health outcomes.

Superagers show greater neuron growth linked to strong memory

Brains of older adults with super healthy cognition grow more new neurons than those of their peers, according to a study from UIC, Northwestern University and the University of Washington.

Digital health access gaps limit patient care and outcomes

Patients are now expected to navigate much of their care online - from seeing their doctor on a screen to booking appointments, refilling prescriptions, and checking test results through health care portals.

Simple blood test measuring piRNAs may help better understand health and aging

Research in Aging Cell indicates that blood levels of particular small non-coding RNAs, which regulate gene expression, may influence how long a person lives.

Muscles retain molecular memory of repeated inactivity

Muscle loss, or atrophy, due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging.

Small RNA molecules can accurately predict survival in older adults

As people age, it becomes harder to know who is on track for healthy years ahead and who may be at higher risk for serious decline.

Barshop Institute at UT Health San Antonio secures major federal funding for longevity trial

Positioning The University of Texas at San Antonio as a national anchor for aging and longevity science, its Sam and Ann Barshop Institute for Longevity and Aging Studies will receive up to $38 million in federal funding for the first nationwide clinical study in healthy longevity.
