Martha's Vineyard Hospital launches study to better understand alpha-gal syndrome

Martha's Vineyard Hospital, a member of Mass General Brigham, has begun recruiting participants for a research study designed to better understand alpha-gal syndrome (AGS), a potentially serious allergic condition associated with lone star tick exposure.

Researchers find alarming rates of CTE in former football players

In a new study from Mass General Brigham, Boston University (BU), and the Concussion & CTE Foundation, researchers found evidence that at least 1-in-4 former NFL players who died between 2016 and 2021 had chronic traumatic encephalopathy (CTE) at the time of their death, a much higher prevalence compared to the general population.

The certification illusion: Why safety seals miss hidden chemical hazards

None of the certification programs consumers rely on to find safer personal care products require laboratory testing of the products they certify, according to a new peer-reviewed analysis.

Study finds distinct patterns of innate immune activity in mental disorders

The immune system may also play a role in mental disorders. Scientists are investigating these links with brain function in greater detail, and new findings show that immune changes may differ by disorder type.

New discovery helps identify colorectal cancer patients at risk for metastasis

Researchers from the University of Turku in Finland and Gustave Roussy Institute in France have discovered a molecular mechanism that regulates whether the cells of an aggressive colorectal cancer are conventional or inverted when they spread in the body.

Dysfunctional myelin-producing brain cells contribute to age-related cognitive decline

Brain cells that produce the protective coating around nerve fibers can become dysfunctional with age and may actively contribute to cognitive decline, according to new research.

Loneliness can reprogram the brain to increase alcohol use

Loneliness can reprogram the brain in ways that push alcohol consumption, reports a new preclinical study led by Northwestern University and the Salk Institute for Biological Studies.

Study reveals high prevalence of chronic traumatic encephalopathy among former NFL players

At minimum, nearly a quarter of all former National Football League (NFL) players who died from 2016 to 2021 had confirmed chronic traumatic encephalopathy (CTE) – a neurodegenerative disease linked to repeated head impacts – at death, finds a study published by The BMJ today.

Exposure to drought during pregnancy associated with higher risk of preterm birth

Climate change is making droughts more frequent, prolonged, and intense in many regions of the world, increasing the need to understand their effects on health.

Physical activity declines significantly with age despite good initial health

A recent study from the University of Jyväskylä, Finland, shows that physical activity declines substantially with age, even among older adults who are in good physical condition.

New review challenges the eight-hour ancestral sleep myth

Everyone knows the number. Eight hours. It sits on wellness dashboards, on pediatric handouts, on the label of the melatonin bottle in the medicine cabinet.

Mitochondrial transplantation helps repair donor organs during machine perfusion

Transplant medicine still depends on a limited supply of donor organs, while many retrieved grafts are discarded because ischemia, cold storage, and reperfusion can rapidly damage their cells.

What decades of wine research can, and cannot, tell us about health

A narrative review found that moderate wine intake has repeatedly been associated with lower all-cause and cardiovascular mortality, with proposed mechanisms involving ethanol and grape-derived polyphenols, but the evidence remains largely observational and cannot establish causation. The authors argue that drinking pattern, beverage type, age, cancer risk, and risk-modeling choices all influence how the J-shaped association should be interpreted and how alcohol guidelines are developed.

Ancient dental calculus reveals diverse diets of Japanese commoners

What did ordinary people really eat in premodern Japan, beyond the dishes described in cookbooks and the bones discarded at urban waste pits? Reconstructing past diets at the level of individual food items is remarkably difficult.

From caffeine to trigonelline, coffee has surprising links to muscle biology

A scoping review of 54 studies found that coffee and several coffee-derived bioactive compounds influence pathways linked to skeletal muscle metabolism, including insulin signaling, mitochondrial function, oxidative stress, inflammation, glucose uptake, and protein turnover. Human studies reported associations with greater muscle mass and lower frailty or functional impairment, but most evidence remains observational or preclinical and cannot establish causality.

The diet-Alzheimer’s connection is more complicated than “eat this, avoid that”

A mini-review finds that dietary patterns may influence Alzheimer’s disease through interconnected pathways involving neuroinflammation, insulin resistance, oxidative stress, blood-brain barrier dysfunction, homocysteine, and the gut-brain axis. The authors argue that genetics, sex, age, physical activity, and socioeconomic context may modify these relationships, supporting more individualized approaches to nutrition research and dementia prevention.

Scientists compared 51 longevity studies to see which aging biomarkers respond most reliably

Researchers analyzing 51 longitudinal intervention studies found that reliable generation 2+ DNA methylation biomarkers, particularly those predicting mortality or pace of aging, were the most responsive to interventions aimed at longevity or healthspan. Pharmacological and lifestyle interventions produced the strongest biomarker changes, but the authors cautioned that responsiveness does not yet establish these measures as validated surrogate endpoints for slower aging or longer life.

Higher BPA exposure tracked with higher estrogen and progesterone in women

Researchers found that higher urinary concentrations of BPA and several phthalate metabolites were associated with higher serum estrogen and progesterone levels in 90 premenopausal women from Iran. The cross-sectional study also identified positive associations for combined chemical exposures, although the authors cautioned that the mixture findings are exploratory and cannot establish causality.

Protein degrader shows strong activity against treatment-resistant blood cancers

A first-in-class therapy to target MYC, one of the most sought-after and difficult targets in cancer biology, showed promise in hard-to-treat blood cancers, according to a new preclinical study from The University of Texas MD Anderson Cancer Center published in Blood.

Researchers link GLP-1 drugs to lower tuberculosis risk in type 2 diabetes

A large retrospective cohort study found that GLP-1 receptor agonist use was associated with a lower risk of tuberculosis in people with type 2 diabetes compared with sulfonylureas, metformin, DPP-4 inhibitors, and SGLT2 inhibitors. The observational findings suggest a possible benefit beyond metabolic control, but the authors emphasize that prospective and mechanistic studies are needed to determine whether GLP-1 therapies themselves reduce TB risk.
