Gut changes linger years after polyp removal and may signal colorectal cancer risk

Researchers found that women who had undergone colorectal adenoma resection still showed gut microbiome and fecal metabolome alterations an average of about 12 years later. These persistent changes partly resembled colorectal cancer-associated patterns, suggesting that the host-microbiome axis may remain altered along the adenoma-cancer continuum.

Mental health diagnostic interviews are less consistent than thought

Diagnostic interviews are widely used by mental health professionals to identify conditions such as anxiety, bipolar disorder and depression in adults, but new research led by McMaster University shows that the long considered "gold standard" may not be as consistent as previously thought.

Adding herbs and spices makes people choose more vegetables

Enhancing vegetable flavor with spices and offering larger servings can significantly improve vegetable intake in cafeterias, promoting healthier choices.

Scientists rethink GLP-1 delivery to improve dosing, tolerability, and adherence

The review highlights nanocarriers, microspheres, hydrogels, microneedles, long-acting formulations, and co-formulations as promising but mostly early-stage strategies that still require stronger long-term clinical evidence.

Extreme trait values often have simpler genetic explanations than thought

Researchers at the Icahn School of Medicine at Mount Sinai have found evidence that people who fall at the extreme high or low ends of certain traits, such as cholesterol, blood glucose, height, and age at menopause, are more likely to have a simple genetic explanation than previously thought.

How heat-smart cities can protect outdoor recreation in a warming world

This review shows how rising humid heat threatens the health benefits of nature-based recreation in tropical cities. The authors call for heat-smart urban planning, targeted advisories, and inclusive strategies that keep outdoor activity safe, accessible, and beneficial.

NTU Singapore scientists develop seed-sized robot for precision surgical procedures

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a tiny seed-sized robot that can navigate across soft and uneven surfaces to perform five surgical functions wirelessly, paving the way for developing robots to make surgeries and medical treatments more precise.

Ongoing nausea in pregnancy may flag anxiety and depression risk

Persistent or severe nausea during pregnancy was linked to higher maternal anxiety and depressive symptoms across gestation. The study found little consistent evidence that nausea worsened most perinatal outcomes, suggesting it may serve mainly as a clinical warning sign for psychological burden.

Diet and inflammation may play a role in progressive vitiligo

A small case-control study linked higher Dietary Inflammatory Index scores with progressive vitiligo, suggesting that pro-inflammatory dietary patterns may be associated with disease occurrence or progression. The findings support further research into diet, inflammation, and the gut-skin axis as potential targets for vitiligo prevention and management.

Blood carotenoids offer the clearest signal of fruit and vegetable eating habits

The review finds that several candidate biomarkers may help estimate fruit and vegetable intake more objectively than self-reported dietary tools, but most remain limited by specificity, sampling burden, supplement use, or incomplete validation. Blood and skin carotenoids appear strongest for habitual intake, while vitamin C, folate, urinary flavonoids, hippuric acid, and potassium may be more useful for short-term intake or intervention adherence.

Study identifies major causes of fatigue among disaster responders

Real time data collected during the 2024 Noto Peninsula earthquake response show that unclear tasks and command structures, and lack of meal- and rest breaks increased self-reported fatigue among disaster responders.

Smartphone overdependence may signal higher alcohol and smoking risk in teens

Higher smartphone overdependence was significantly associated with greater odds of self-reported lifetime alcohol and tobacco use among more than 100,000 Korean adolescents. The study found graded dose-response patterns, with earlier initiation and heavier alcohol or smoking behaviors linked to a higher adjusted probability of high-risk smartphone overdependence.

GLP-1 drugs may help curb addiction by targeting reward pathways

GLP-1 receptor agonists, already used for Type 2 diabetes and obesity, show promise in reducing alcohol and drug-seeking behaviors through central reward and dopamine-related pathways. Most evidence remains preclinical, with limited early human data, so larger clinical trials are needed before these drugs can be recommended for addiction treatment.

How food and alcohol cues leave different signatures in the brain

Food and alcohol cues appear to engage partially distinct EEG oscillatory patterns, with food cues linked mainly to increased delta activity and alcohol-related processing showing alpha and delta differences in key contrasts. The effects were strongest in participants with relatively higher AUDIT scores, but neural changes were small and subjective cue responses were more robust.

How does the brain recognize new faces and places in milliseconds?

This Communications Biology study used intracranial EEG in 22 epilepsy patients to map how the human brain processes new images of faces and places within milliseconds.. It found that visual information flows from the occipital cortex through parallel dorsal and ventral pathways toward frontal and limbic regions, with distinct timing patterns for faces and places.

New wristband algorithm detects sudden cardiac arrest with high accuracy

A smart-technology wearable wristband device may be able to automatically detect cardiac arrest, which could lead to faster medical assistance and increased survival odds when cardiac arrest occurs outside of a hospital, according to new research published today in Circulation: Arrhythmia and Electrophysiology, a peer-reviewed scientific journal of the American Heart Association.

Low-frequency ultrasound waves directly manipulate blood flow properties

For decades, ultrasound has been associated with diagnostics – a routine scan in a hospital room, a monitor displaying organs, tissues, or the first image of a baby.

Aged immune cells may drive memory decline by releasing a brain-aging protein

A preclinical mouse study in Immunity suggests that aged circulating CD8+ T cells can disrupt hippocampal function and impair learning and memory. The findings point to granzyme K, a secreted factor linked to age-associated CD8+ T cells, as a potential target for restoring aspects of cognition in aging.

Fewer radiotherapy sessions for prostate cancer show minimal side effects

Two larger doses of radiotherapy for prostate cancer cause no additional side effects compared to the standard five doses of radiotherapy, according to results presented at the Congress of the European Society for Radiotherapy and Oncology (ESTRO 2026).

Evidence shows RF-TC improves seizure control by altering brain networks

Drug-resistant epilepsy affects millions of people worldwide and remains one of the most difficult neurological disorders to treat. For patients whose seizures continue despite medication, surgical removal of seizure-causing tissue can be effective.
