Massive genetics study shows what truly separates and unites 14 psychiatric disorders

This large-scale genomic analysis of 14 psychiatric disorders shows that most heritable risk is shared across five broad genetic factors, with only limited disorder-specific variation. The study maps where risks converge or diverge biologically, revealing distinct cell type signatures and developmental pathways that may guide future diagnostic and therapeutic frameworks.

Scientists outline how organ rejuvenation strategies could solve the donor shortage

Researchers outline why organs from older donors are often discarded and identify the biological and immunological pathways that make them vulnerable to injury. They also highlight emerging rejuvenation technologies including machine perfusion, senotherapeutics, and regenerative strategies that could safely expand the donor pool.

How ultra-processed foods shape Crohn’s disease risk and what dietary strategies can really help

This narrative review synthesizes evidence showing that higher intake of ultra-processed foods is consistently associated with increased Crohn’s disease risk, with mechanistic pathways implicating emulsifiers, carrageenan, maltodextrin, titanium dioxide, sweeteners and salt. It also highlights that minimally processed dietary strategies, including EEN and CDED, show therapeutic promise, particularly in pediatric Crohn’s disease.

New findings show why the human intestine uniquely presents gluten to T cells

Human intestinal M cells function as dendritic cell-like antigen-presenting cells, displaying constitutive MHC-II activity and specialized machinery for processing gluten. Their ability to deamidate and present gliadin peptides positions them as key initiators of immune responses relevant to coeliac disease.

How specific foods reshape oxidative stress responses during and after high-intensity training

Carbohydrate-rich foods blunt acute oxidative stress during fasted high-intensity exercise, while polyphenol-rich foods accelerate early recovery by reducing post-exercise ROS. Findings highlight how nutrient timing shapes redox responses in sedentary young women undergoing resistance-circuit HIIT.

What happens to your body when you eat takeaway food too often?

This study of 8,556 US adults shows that frequent takeaway food consumption is associated with a higher energy-adjusted Dietary Inflammatory Index and adverse cardiometabolic markers. The findings suggest that reducing takeaway intake and lowering dietary inflammatory potential may improve long-term cardiometabolic health.

Preoperative MRI offers no survival benefit for early-stage breast cancer patients

Patients with stage 1 or 2, hormone receptor (HR)-negative breast cancer had similar five-year rates of locoregional recurrence whether or not they underwent preoperative breast magnetic resonance imaging (MRI) in addition to diagnostic mammography to determine the extent of their cancer, according to results from the phase III Alliance A011104/ACRIN 6694 clinical trial presented at the San Antonio Breast Cancer Symposium (SABCS), held December 9-12, 2025.
