Study proposes genetic basis for autism’s strong sex bias

Autism has a significant and enduring sex bias, with roughly four boys diagnosed for every girl. For many years, experts have believed this disparity arises primarily from diagnostic inequities because much of autism research - and the screening tools that grew out of it - has historically focused on boys, effectively setting a male standard for what autism "looks like."

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.

Gut microbial butyrate enhances mucosal vaccine antibody responses

A research team from POSTECH and ImmunoBiome in Korea, led by Professor Sin-Hyeog Im, has uncovered a new mechanism showing how butyrate-a short-chain fatty acid produced by gut commensal bacteria-enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy.

Peptide-based platform marks a major step toward needle-free diabetes care

For more than a century, oral insulin has been considered a "dream" therapy for diabetes, hindered by enzymatic degradation in the digestive tract and the absence of a dedicated intestinal transport mechanism. Consequently, many patients must rely on daily insulin injections, which can significantly reduce their quality of life.

Alterations in liver metabolism experienced by individuals with Down syndrome

Researchers at the University of Colorado Anschutz Linda Crnic Institute for Down Syndrome (Crnic Institute) have uncovered compelling evidence that individuals with Down syndrome experience significant alterations in liver metabolism, including elevated levels of bile acids in the bloodstream and other biomarkers of liver dysfunction.

The gut is not just digestive and new evidence shows it actively controls brain function

This comprehensive review synthesizes a decade of human and animal research to explain how the gut and brain communicate through hormonal, neural, immune, and microbial pathways. It highlights how disruptions in these pathways contribute to gastrointestinal, metabolic, and neurological disorders, and how modern therapies are beginning to exploit gut–brain signaling for clinical benefit.
