At Social Security, these are the days of the living dead

Rennie Glasgow, who has served 15 years at the Social Security Administration, is seeing something new on the job: dead people.

Disrupted muscle clocks linked to accelerated aging in shift workers

Muscle cells contain their own circadian clocks and disrupting them with shift work can have a profound impact on aging, according to new research.

A decade of discovery in the science of healthy aging and human longevity

It's notable when a scientific study reaches the decade mark, but when the topic is the healthy aging of people who have lived 10 times as long, it just means there's still a lot more to learn.

Growing up poor leaves lasting health scars, researchers find

A large cross-national study across 29 high-income countries found that childhood poverty significantly increases the risk of frailty in older age. The association persists even after accounting for education, wealth, and other life-course factors.

Happiness can be shaped by external circumstances or internal states

What is the secret to happiness? Does happiness come from within, or is it shaped by external influences such as our jobs, health, relationships and material circumstances? A new study published in Nature Human Behaviour shows that happiness can come from either within or from external influences, from both, or neither – and which is true differs across people.

Boosting glucose metabolism in glial cells reduces neurodegeneration in fruit flies

Researchers from Tokyo Metropolitan University have discovered that impaired glucose metabolism in glial cells, a type of cell in our nervous system, plays a key role in the degeneration caused by Alzheimer's disease.

Phthalates in plastics linked to over 350,000 heart deaths worldwide

A global modeling study in eBioMedicine links phthalate exposure from plastics, especially DEHP metabolites, to over 356,000 cardiovascular deaths in 2018. Exposure was highest in Asia, the Middle East, and Africa, disproportionately affecting lower-income countries.

MRI technique reveals the heart's functional age

Scientists at the University of East Anglia (UEA) have developed a revolutionary new way of uncovering the 'true age' of your heart using MRI.

Study shows safe outcomes for PCI performed in ambulatory surgery centers

The first study evaluating Medicare patients undergoing percutaneous coronary intervention (PCI) in ambulatory surgery centers (ASCs) demonstrated good safety outcomes, such as mortality and adverse event rates at 30 days, compared to outpatient hospital departments, but were less likely to use certain technologies.

Study uncovers how a mobile genetic element hijacks human cells

Viruses are known to use the genetic machinery of the human cells they invade to make copies of themselves. As part of the process, viruses leave behind remnants throughout the genetic material (genomes) of humans.

NAD+ restoration improves mitochondrial function in Werner syndrome cells

A new research paper was published in Aging (Aging-US) on April 2, 2025, as the cover of Volume 17, Issue 4, titled "Decreased mitochondrial NAD+ in WRN deficient cells links to dysfunctional proliferation."

New breakthrough could lead to early detection of knee osteoarthritis

The number of people suffering from osteoarthritis is expected to top 1 billion by 2050. The biggest risk factor for the prevalent, often painful, chronic joint disease is aging. And like aging, there is currently no way to stop it.

What predicts belief in the afterlife? A massive global study has answers

A large global study of over 202,000 adults in 22 countries found that belief in an afterlife is shaped not only by religious exposure in childhood, but also by early emotional and familial experiences. Weekly religious attendance at age 12 was the strongest and most consistent predictor of adult afterlife belief.

Spatial working memory remains stable in older adults with autistic traits

There is no difference over time in the spatial working memory of older people who have autistic traits and those who are neurotypical, finds a new study led by UCL researchers.

Caffeine increases brain complexity during sleep and shifts it toward a critical state

Caffeine shifts brain activity during sleep by increasing EEG complexity and reducing long-range temporal correlations, particularly in non-REM (NREM) sleep. These changes reflect a movement toward a “critical regime” of neural processing, more pronounced in younger adults.

Researchers tie childhood vitamin D shortfalls to adult heart disease

Low childhood levels of 25-hydroxyvitamin D were linked to a significantly higher risk of early adult-onset atherosclerotic cardiovascular disease (ASCVD). The association remained even after accounting for conventional childhood risk factors and persisted across multiple analyses.

Clusterin identified as key marker for aging in blood stem cells

In recent years, there has been a growing trend of an aging patient population and an increasing prevalence of age-associated diseases, underscoring the need for advancing research into the biological mechanisms of aging.

Virtual reality game using scents boosts cognitive function in older adults

As the global population ages, supporting older adults in maintaining their cognitive and memory functions has become a pressing concern.

New protein target offers hope for treating high blood pressure and aortic aneurysms

Oxidative stress can occur when our cells are exposed to harmful molecules called "reactive oxygen species" over time. These reactive oxygen species can damage cells and are found in important disease states, such as high blood pressure and aortic aneurysms.
