Vegetarian and vegan diets can support healthy growth when carefully planned with appropriate supplementation, finds a major new meta-analysis – the most comprehensive study to-date of plant-based diets in children.

Increased volume of epicardial adipose tissue, detected by cardiovascular imaging, was found to be associated with greater myocardial injury after a myocardial infarction.

Pain perception in affected individuals is more strongly influenced by learned fear than in healthy individuals. Changes along the gut-brain axis related to chronic inflammation may explain this.

New analysis from a WHO global expert committee on vaccine safety has found that, based on available evidence, no causal link exists between vaccines and autism spectrum disorders (ASD). The conclusion reaffirms WHO's position that childhood vaccines do not cause autism.

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.

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.

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.

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.

A strategy for advance care planning (ACP) that included automated outreach from staff who contacted patients to offer assistance significantly boosted the number of patients who completed documentation outlining their wishes in times of serious illness, new research finds.

A new UBC Okanagan study found that people who microdose psychedelics feel better on the days they take them-but those boosts don't seem to last.

Do your kids play a lot of computer games? Some may end up gaming a little too obsessively. Researchers have identified the most important warning signs.

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.

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.

New research from the University of Vermont reveals exposure to smoke from Canadian wildfires in the summer of 2023 led to worsening asthma symptoms in children in Vermont and upstate New York.

A new study published today in The Lancet showed a significant survival benefit for patients with oropharyngeal cancers who were treated with proton therapy (IMPT) compared to those treated with traditional radiation therapy (IMRT).

Routine mammograms are a critical tool for breast cancer screening. However, they may also hold crucial, potentially untapped information about a person's risk for cardiovascular disease, the number one cause of death among adults.

Annual prescriptions for drugs to treat attention-deficit/hyperactivity disorder (ADHD) increased 157 percent in Ontario from 2015 to 2023, according to a new study from researchers at ICES, North York General, and The Hospital for Sick Children (SickKids).

Distinct psychiatric disorders have more in common biologically than previously believed, according to the largest and most detailed analysis to date of how genes influence mental illness.

A new study from Flinders University offers insight into how two of the world's most popular beverages, coffee and tea, may influence bone health in older women.

A team of researchers at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and Miguel Hernández University of Elche (UMH), has reconstructed for the first time how the cerebellum establishes its connections with the rest of the brain during the earliest stages of life.
