Microplastics transport toxins and antibiotic resistance across ecosystems

Microplastics are often viewed as pollutants in their own right, but their environmental impact may extend far beyond the plastic particles themselves.

New study uncovers bacterial route to testosterone production

Many prostate cancers depend on androgen hormones, including testosterone, to grow. That is why treatments for advanced disease often try to reduce testosterone production or block its effects.

Researchers uncover how Atg2 drives autophagosome formation

Autophagy is an intracellular degradation mechanism in eukaryotes. The autophagosome, which encloses damaged or excess cellular material for degradation, is constructed from lipids supplied by the endoplasmic reticulum (ER), via the lipid transfer protein Atg2.

Gut bacterial metabolite linked to inflammation in liver disease

Researchers have identified a link between specific activities in gut bacteria and the liver disease PSC.

Dual-drug microneedle patch targets inflammation and fat browning

The worldwide obesity crisis has become a dominant public health crisis across the globe. Over 3 billion people worldwide currently suffer from obesity, and forecasts warn the number will rise above 4 billion by 2035, accounting for more than half the global population.

Mosaic nanoparticle vaccine boosts broad mucosal coronavirus immunity

The persistent threat of emerging coronaviruses highlights the critical need to establish frontline defenses directly at the respiratory entry portal.

MXene-based hydrogel offers dual-action treatment for periodontitis

Periodontitis is a highly prevalent chronic inflammatory disease worldwide. It leads to periodontal tissue destruction, alveolar bone resorption, and ultimately tooth loosening and loss, severely impacting patients' oral function and quality of life.

Physics-informed AI framework improves aortic aneurysm stress prediction

Ascending thoracic aortic aneurysms often progress silently, but once dissection or rupture occurs, they can cause severe mortality before hospital arrival or during admission.

Gut bacterial molecule discovered to drive serious bile duct disease

Researchers at the University of Oslo and Oslo University Hospital have, together with international collaborators, discovered that a small molecule made exclusively by gut bacteria can actively drive disease in the bile ducts and worsen primary sclerosing cholangitis (PSC), a serious liver and bile duct disease.

Lab-grown micro bladder helps explain why urinary tract infections return

A lab-grown micro bladder may explain why urinary tract infections (UTIs) return so frequently, according to a study led by researchers at UCL, the University of Oxford and the University of Leicester.

Tumor environments sculpt diverse natural killer cells for cancer therapies

For decades, natural killer (NK) cells have been classified into two main groups based on surface markers: one specialized for cytokine production and the other for direct killing.

Most oncology AI research overlooks critical patient safety and privacy

Flinders University researchers were part of an international team that conducted a scoping review that identified 2,441 records and found just 32 studies examined how cancer patients, survivors and carers feel towards generative AI being used in their care.

Crucial brain stem cells rely on metabolic pathways to make decisions

As the human brain takes shape before birth, a remarkable type of stem cell helps give it many of the features that make it distinctly human.

Extreme long-distance running triggers major surge in body's cannabis-like molecules

A marathon, 100 kilometers or even 230 kilometers in one go: Anyone running such distances puts enormous strain on their body.

Research reveals how natural enzymes transcribe expanded eight-letter genetic code

All known life on earth utilizes the same genetic alphabet, consisting of four letters. Now, researchers at University of California San Diego have demonstrated that one of biology's most essential enzymes can accurately read and transcribe an expanded, eight-letter genetic alphabet.

What your gut microbes may have to do with how your brain ages

This review examines how diet-driven changes in the gut microbiota and microbial metabolites may influence cognitive aging through immune, metabolic, neural, endocrine, and barrier-related pathways. It highlights SCFAs, tryptophan-derived metabolites, and bile acids as key signaling mediators while emphasizing that much of the mechanistic evidence remains preclinical and human evidence is largely associative.

What 107 professional MMA fighters actually ate before and after weigh-in

Professional UFC fighters followed highly structured dietary patterns around competition, sharply restricting carbohydrates, fiber, fluids, and sodium before weigh-in before rapidly increasing carbohydrate, fluid, and sodium intake afterward. Despite aggressive post-weigh-in refueling, carbohydrate intake fell again on fight day, suggesting that some fighters may not fully restore glycogen stores before competition.

What your genes can, and cannot, tell us about your personality

A meta-analysis of 46 cohorts involving 611,037 to 1.14 million participants identified 1,260 lead genetic variants associated with the Big Five personality traits, including 824 in previously unlinked genomic regions. The associations were broadly consistent across cohorts and measurement contexts, while polygenic analyses linked personality-related genetics to health, behavior, psychopathology, and life outcomes, although effects were modest and could not predict individual behavior.

Semaglutide extended lifespan in older female mice, but that was not the only finding

Late-life semaglutide treatment slowed age-related physiological decline, attenuated multiple molecular hallmarks of aging, and extended median lifespan from 742 to 834 days in aged female mice. The drug reproduced many effects of calorie restriction while providing additional benefits in exploratory behavior, spatial memory, and glucose control, suggesting that some effects extend beyond reduced calorie intake alone.
