The link between fish and pregnancy hypertension may start before conception

In a nationwide Japanese cohort of more than 86,000 women, higher fish intake before pregnancy was associated with lower odds of early-onset hypertensive disorders of pregnancy, while fish intake during pregnancy showed different associations with late-onset disease, particularly among women who had not previously given birth. Total dietary omega-3 and omega-6 PUFA intake showed much less consistent associations, suggesting that the relationship with fish consumption may not be explained by total PUFA intake alone.

New base editing techniques accurately modify genes in human embryos

A study by researchers at Columbia University Vagelos College of Physicians and Surgeons has found that new cutting-edge techniques can accurately edit genes in human embryos-giving scientists indispensable tools for understanding normal human development-but has also uncovered important risks that currently preclude the use of the techniques in the clinic.

Hormone therapy during menopause transition associated with lower heart disease risk

A study led by Virginia Commonwealth University and the University of Pittsburgh provides pivotal insights into one of the most debated questions in women's health: how does hormone therapy for menopause symptoms affect cardiovascular disease risk when used in peri- or early postmenopause?

A common drink pattern was linked to less sleep and more fatigue in soldiers

A cross-sectional study of 1,155 active-duty Spanish Army personnel identified three distinct co-consumption profiles based on the frequency of caffeinated beverage, energy drink, and sugar-sweetened beverage use. Compared with the lower-frequency profile, the higher-frequency profile was associated with about 14 minutes less sleep per night, lower sleep efficiency, and greater habitual physical fatigue, although the study cannot establish causality or quantify caffeine or sugar exposure.

Physics-guided framework doubles digital pathology resolution for cancer screening

Digital pathology relies on high-resolution imaging for accurate cancer diagnosis, yet high-magnification systems remain slow and costly for large-scale screening.

What mothers eat in pregnancy may shape a child’s weight years later

A prospective study of 252 mother-child pairs found that higher combined maternal fruit and vegetable intake during pregnancy was associated with lower odds of overweight or obesity in children at age four. Total and natural fruit juice showed no association, whereas higher commercial fruit juice intake was associated with increased odds, though the authors emphasized that this finding was exploratory.

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.

New V-UNet model improves efficient medical image segmentation

Segmentation tools help doctors identify and delineate tumors, lesions, and other abnormalities in medical images.

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

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.
