Bariatric surgery restores menstrual cycles and reduces polycystic ovaries in obese women

Metabolic bariatric surgery improves menstrual cycle frequency and symptoms of polycystic ovaries in women living with obesity, a new study from the University of Surrey reports.

Scientists traced a hidden immune route that may worsen tau-linked brain damage

In a mouse model of tauopathy, conventional type 1 dendritic cells (cDC1s) cross-presented brain-derived antigens in deep cervical lymph nodes, priming CD8+ T cells that accumulated in the brain and promoted neurodegeneration. Disrupting cDC1s or their cross-presentation activity reduced CD8+ T-cell infiltration and protected against neuronal loss, while human primary tauopathy samples also showed increased brain CD8+ T cells, although cDC1 involvement in humans remains unconfirmed.

Plant-based fats improve long-term survival for prostate cancer patients

Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health.

New scLS algorithm advances gene expression trajectory analysis

Single-cell RNA sequencing (scRNA-seq) is a method to measure gene expression of individual cells, allowing observation of various cellular processes, including cell differentiation, the cell cycle, and stimulus-response for each unique cell instead of averaging across millions of cells.

Early baby swimming linked to a small IQ advantage by preschool age

A prospective cohort study of 1,935 mother-child pairs examined whether baby swimming during the first 6 months of life was associated with IQ and cognitive performance at ages 4 to 6 years. Swimming participation was associated with modestly higher scores across several cognitive domains, but the researchers cautioned that the observational findings cannot establish causation and may partly reflect socioeconomic and family-level differences.

New guideline updates medications for preventing migraine in adults

To help clinicians determine which medications may be most effective at preventing migraine in adults, the American Academy of Neurology (AAN) and American Headache Society (AHS) have issued a joint practice guideline update with evidence-based recommendations, published on August 31, 2026, in Neurology®, the medical journal of the American Academy of Neurology, and in Headache, the official journal of the American Headache Society.

How far your eyes move may change what you see

Researchers found that the distance the eye travels during a rapid gaze shift changes post-saccadic visual sensitivity by altering the spatial-frequency information carried by retinal luminance transients. Larger saccades preferentially enhanced lower-frequency, coarser visual information, while very small saccades could increase the relative visibility of finer, higher-frequency information.

Breastmilk from cannabis users showed differences, but cannabis may not be the whole story

A narrative review found that maternal cannabis use may be associated with differences in breastmilk fat, protein, lactose, and the immune factor secretory immunoglobulin A, but evidence comes primarily from only two human studies and remains limited and inconsistent. The authors stress that maternal diet, food security, socioeconomic circumstances, and other forms of adversity could confound these associations and should be incorporated into future research.

Your skin may offer clues about how many fruits and vegetables you eat

In an exploratory study of 137 Australian adults, skin yellowness measured by reflectance spectroscopy was associated with combined fruit and vegetable intake, fruit intake alone, total carotenoid intake, body fat percentage and skin color. The findings suggest skin measurements could provide an objective dietary biomarker, but the researchers caution that skin color, ethnicity and other individual characteristics may influence how the measurements are interpreted.

Researchers identify early molecular warning signs of inflammatory bowel disease

Researchers have uncovered early molecular warning signs of inflammatory bowel disease, revealing the condition can begin before symptoms appear and continue silently even when patients appear well.

Updated consensus offers new roadmap for childhood bedwetting care

Nocturnal enuresis (NE) in school-age children is more than a nighttime inconvenience: when persistent, it can affect self-esteem, sleep, family life and social functioning.

Study identifies KRAS G12C as a precision-medicine target in genitourinary cancers

A new research paper was published in Volume 17 of Oncotarget on August 19, 2026, titled "Incidence of KRAS G12C mutations in genitourinary malignancies; emerging target in precision medicine."

Sunlight, blood sugar and diabetes: a new study finds an intriguing connection

Higher short-term ambient UVA exposure was associated with modestly lower blood glucose levels, particularly during winter, in a large UK Biobank analysis. Separately, more frequent solarium use, used as a proxy for habitual sunlight exposure, was associated with a lower hazard of type 2 diabetes, although the observational findings do not establish causality.

Internet-controlled brain implant enables remote neural stimulation and drug delivery

A researcher in Chicago remotely controls a miniaturized brain implant in Daejeon, Korea - over the internet. Korean researchers have developed a wireless device that can deliver drugs and light to precisely modulate targeted neurons from anywhere in the world.

Breast milk fats may reflect more than the fats a mother eats

A cross-sectional study of 109 breastfeeding women in the Netherlands found that maternal intakes of omega-3 and omega-6 PUFAs and trans fats were associated with corresponding fatty acid proportions in human milk. The researchers also identified links involving dietary fiber, diet quality and several micronutrients, although whether these relationships reflect direct biological effects or broader dietary patterns remains uncertain.

GLP-1 drugs may reshape obesity care, but clinicians still have questions

Interviews with 11 healthcare professionals in a UK specialist weight management service found generally positive attitudes toward injectable GLP-1 drugs, alongside limited formal training and uncertainty about how the medications should be integrated with behavioral care. Participants anticipated potential benefits for confidence and weight management but also raised concerns about treatment discontinuation, behavioral engagement, and evolving professional responsibilities.

Emergency diagnoses of medical conditions predict worse patient survival

Patients diagnosed with conditions after an emergency hospital admission or an emergency room visit face a higher risk of death than those diagnosed in non-emergency settings, according to a large population-based study by Emma Whitfield and colleagues from University College London, UK, published August 25th in the open access journal PLOS Medicine.

SBRT improves bowel health related quality-of-life in patients with localized intermediate-risk prostate cancer

Results of the NRG Oncology NRG-GU005 clinical study comparing stereotactic body radiation therapy (SBRT) to moderately hypofractionated intensity-modulated radiation therapy (MH-IMRT) for patients with localized intermediate risk prostate cancer indicate that the use of SBRT improved bowel health related quality of life (HRQOL) in this patient population.

Consistent meal logging drives major weight loss in app users

The people who log their meals most days of the week lose the most weight. This is the central finding of a peer-reviewed study of 5132 MyNetDiary users, published on August 13, 2026, in the Journal of Medical Internet Research.
