High immune cell ratios may predict future Alzheimer's disease risk

Circulating white blood cells called neutrophils are some of the immune system's first responders. Their numbers shoot up during infection and inflammation, shifting the ratio of neutrophils to other types of immune cells in the blood.

AI predicts retinal age to identify early signs of biological aging

There may be some truth to the saying "the eyes are the window to the soul." Age-related changes are reflected in the retina, the light-sensitive tissue at the back of the eye.

Heatwaves above 38 °C significantly spike cardiovascular cases in middle-aged populations

A novel study has revealed a link between extreme weather and the risk of cardiovascular disease among middle-aged and older adults in 157 Chinese cities. Based on a city's climate and location, exposure to extreme heat, cold, and precipitation each increases the risk of heart disease. The findings of the study in the American Journal of Preventive Medicine, published by Elsevier, provide evidence for policymakers across different regions to develop targeted strategies protecting vulnerable populations during extreme climate events.

Muscle energy recovery may explain fatigue in cancer survivors

Even apparently healthy cancer survivors often complain of extreme fatigue. They have finished treatment, the scans are clear, but they feel hollowed out, unable to walk to the mailbox or stay awake through dinner.

Having more children associated with lower stroke risk for women

While some say having lots of kids can make you lose your faculties, a new study suggests otherwise.

Nestlé and NTU Singapore announce research partnership on aging and women's health

Nestlé and NTU Singapore today announced a multi‑year joint research partnership to advance the scientific understanding of how nutrition supports healthy longevity and women's health.

Antiretroviral therapy reduces biological aging in people living with HIV

A major study presented today at ESCMID Global 2026 has found that antiretroviral therapy (ART) reduces accelerated biological ageing in people with HIV (PWH) by nearly four years, a finding that could transform how clinicians monitor HIV treatment and long-term health outcomes.

Proteomics and AI bring earlier risk prediction into sharper focus

This review examines how high-throughput proteomics is expanding precision medicine by improving biomarker discovery, disease prediction, and drug development. It also shows how AI is helping researchers interpret complex proteomic data while highlighting major barriers such as standardization, validation, and clinical translation.

Yeast model reveals mechanisms behind premature aging from progerin

A new research paper was published in Volume 18 of Aging-US on April 3, 2026, titled "Modeling premature aging in yeast via the expression of Progerin."

Visceral fat strongly linked to urinary incontinence in women

The accumulation of fat in the abdominal region, especially visceral fat (fat that accumulates between organs), significantly increases the risk of stress urinary incontinence in women.

Age shapes melanoma progression and immune response

Cancer risk increases with age and is often more aggressive and difficult to treat in older adults. However, fewer than 10% of mouse studies use aged animals, with most relying on mice roughly equivalent to humans in their early 20s.

Childhood flu infection leaves lasting immune imprint

A study reveals how childhood flu infections impact long-term mortality risk, highlighting implications for vaccination and future outbreak management.

Fast answers and extra research drive AI healthcare use in America

One in four U.S. adults - the equivalent of over 66 million Americans - report having used artificial intelligence tools or chatbots for physical or mental healthcare information or advice, according to new research released today from the West Health-Gallup Center on Healthcare in America.

How the immune system may influence Alzheimer’s, Parkinson’s, and related diseases

This review argues that neurodegeneration is shaped not only by toxic protein buildup but also by immune signaling, with microglia and T cells able to either protect the brain or worsen damage depending on context. It also highlights aging, head injury, and viral infection as major forces that reshape CNS immunity and may influence disease progression and future treatment strategies.

Researchers discover a molecular signature to flag dysfunctional aging cells

UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation and reversed liver damage in mice - even while the animals remained on an unhealthy diet.

Epigenetic changes allow cancer cells to shift identity and survive drugs

Cancer drugs are designed to shut tumors down. But sometimes, in the very act of attacking a tumor, treatment can also help a small fraction of cancer cells become harder to kill. A new study from researchers at the Institute for Systems Biology (ISB) shows that cancer cells may begin escaping therapy much earlier - as the therapy itself triggers a stress response that drives some cancer cells into a temporary drug-tolerant state.

Researchers discover how stress signals weaken the aging immune system

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their effectiveness. Normally, HSCs can both self-renew and generate a balanced mix of blood cells, but over time they produce fewer new cells, favor certain cells such as myeloid cells over lymphoid cells, and struggle to support a robust immune response.

Study links ultra-processed food intake to poorer thigh muscle quality

A Radiology study of 615 adults at risk for knee osteoarthritis found that higher ultra-processed food intake was associated with greater fat infiltration in thigh muscles on MRI, a marker of poorer muscle quality. The association remained after adjustment for BMI, was stronger in models using abdominal circumference, and did not differ significantly by sex.

Older adults show high willingness for Alzheimer’s blood tests

Northwestern University psychologist Andrea Russell sees older adults with early cognitive impairment riddled with anxiety. Some worry a missed word or forgotten appointment could signal Alzheimer's disease.

Middle-aged Americans face rising loneliness and mental health challenges

Frank Infurna first started thinking about the plight of middle-aged adults 10 years ago. He conducted a monthly survey, asking about their health, well-being, relationships, and life events.
