New machine learning tool identifies hidden epigenetic disease patterns

In a study recently published in Nature Communications, researchers from Berlin, Potsdam, and Jena present a new method for analyzing the epigenome, the genome's control system that determines which genes are switched on and off.

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.

Visual storytelling transforms scientific evidence into meaningful public health action

Even as the scientific community has reached broad consensus that infectious pathogens, such as viruses, can spread through airborne transmission in virus-laden aerosols, one fundamental challenge remains.

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.

AI identifies key gene driving aging in blood stem cells

Stem cells possess the unique ability to self-renew and transform into different types of cells. For example, rare hematopoietic stem cells found in bone marrow can become any type of blood cell.

New lensless imaging method captures clearer images of moving objects

With the rapid development of smartphones, wearable devices, and portable medical diagnostic systems, increasingly stringent requirements have been placed on imaging systems: they are expected to provide clear images while remaining sufficiently compact and lightweight.

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.

Understanding opioid risks can help prevent accidental overdoses

According to numbers calculated from the CDC, approximately 80,000 people died last year from a drug overdose, which represents about 21 deaths per 100,000 residents in the U.S. alone. Overdose deaths are preventable, and in most of the cases we see, they are completely accidental.

Tick-borne alpha-gal syndrome poses potential risks during blood transfusions

A new multi-institute study led by researchers at Dartmouth Health and Geisel School of Medicine at Dartmouth suggests that alpha-gal syndrome, the tick-borne disease that can result in a chronic allergy to meat and animal byproducts, also may complicate certain patients' ability to safely receive a blood plasma or platelet transfusion.

Recipient reputation helps stabilize cooperation in large communities

When one person helps, or refuses to help, another in public, this may change not only the provider's reputation but also the recipient's.

An 11-year study found the same social media pattern again and again

Across 11 annual U.S. surveys involving about 183,000 adults, higher social media use was consistently associated with self-reported depression, with social media ranking among the strongest predictors in machine-learning models. SHAP analyses suggested that social media use became a stronger positive signal for depression at around 150 minutes per day, although the authors stress that this is not an established clinical threshold and requires longitudinal and experimental testing.
