Study links gut microbiome health directly to ovarian aging processes

A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome (the collection of all bacteria and other microbes present) of the gut and ovarian health and function.

Inflammatory signals from vesicles increase cancer cell aggressiveness and invasiveness

Pro-inflammatory M1 macrophages involved in immune responses accelerate the progression of melanoma through the extracellular vesicles they secrete, a recent study from the University of Eastern Finland shows. The findings were published in Cell Communication and Signaling.

Research suggests new therapeutic targets for broad-spectrum antiviral drugs

Coronaviruses not only use the machinery of the human cells they infect: they modify it to achieve optimal conditions to produce viral proteins and thus spread more quickly. This is the main conclusion of a study by Pompeu Fabra University published in Nature Communications.

Brain reward responses shift based on expectations about sweeteners

Elena Mainetto, from Radboud University, Margaret Westwater, from the University of Oxford, and colleagues at the University of Cambridge explored whether they could change how much people enjoy beverages containing sugar or artificial sweeteners by manipulating previous expectations about the drinks.

Experts identify safest and most effective diets for IBS management

This review in Nutrients evaluates the scientific evidence, clinical effectiveness, and safety of major dietary strategies for irritable bowel syndrome, including traditional advice, low-FODMAP, gluten-free, Mediterranean, and starch- and sucrose-reduced diets. It concludes that while the low-FODMAP diet has the strongest short-term evidence, no single approach fits all patients, and dietitian-led personalization is essential.

High-dose curcumin fails to produce lasting gut microbiome changes in IBD patients

In an open-label study of 29 men, including patients with ulcerative colitis and Crohn’s disease in remission, 6 g per day of curcumin for eight weeks led to modest, transient shifts in gut microbiota composition without sustained restructuring. Despite achieving high fecal concentrations and minimal systemic bioavailability, curcumin did not produce durable microbiome changes, and disease activity scores remained stable.

COVID-19 ARDS survivors face lasting disability and high late mortality, researchers report

In this single-center ambispective cohort of 283 Polish patients with COVID-19–related ARDS requiring invasive mechanical ventilation, cumulative mortality reached 44.5% at four years after ICU admission. Among survivors, substantial proportions reported persistent functional limitations, insomnia, fatigue, and reduced quality-adjusted life years.
