A comprehensive analysis of 383 U.S. cities reveals a striking pattern: most have rings of isolation in suburban areas and segregated pockets of near the urban core, that are shaped by race, wealth, and proximity to downtown, finds a new study by UCL researchers.

Many patients with inflammatory bowel disease (IBD) suffer from abdominal pain even between acute inflammatory flare-ups. Altered processing of pain in response to fear may be involved. This is the conclusion of a research team at Ruhr University Bochum, Germany, involving Dr. Hanna Öhlmann. The researchers compared the perception of pain in healthy individuals and patients with IBD using a learning experiment. Based on their findings, they recommend the development of personalized treatments that take such psychological mechanisms into account. The study was published in the scientific magazine PAIN on November 26, 2025.

Words reflecting diversity language have appeared less frequently in grants awarded by the National Institutes of Health (NIH) since the 2024 US presidential election, with a 25% relative decrease between January 2024 and June 2025, finds a study in the Christmas issue of The BMJ.

The old proverb “it takes a village to raise a child” also applies to preventing youth suicide, according to UBC Okanagan researchers who found that community support is essential.

In Canada, suicide is the fourth leading cause of death among children under 14 and the second for youth and young adults between 15 and 34 years old. The UBCO Faculty of Health and Social Development researchers say governments, schools and community agencies need to rethink how youth suicide prevention efforts are designed.

The U.S. is largely self-sufficient in agricultural food production, supported by a well-developed storage and interstate trade system. However, extreme weather events put increasing pressure on agriculture, potentially impacting the country’s ability to provide food for its growing population and underscoring the importance of maintaining a resilient food supply chain. A new study from the University of Illinois Urbana-Champaign, published in the Proceedings of the National Academy of Sciences, looks at U.S. interstate trade for agricultural products, analyzing how weather events in one area can have wide-ranging effects on food production.
