Spinach, almonds and sweet potatoes are celebrated as some of the healthiest foods on the planet. But for the millions of Americans living with inflammatory bowel disease (IBD), a new study from the UNC School of Medicine suggests that these same foods may be quietly worsening gut inflammation through a compound most people have never heard of.

Imagine the body's immune cells as a neighborhood cleanup crew. When all is healthy, macrophages roam tissues, clearing away cellular debris and helping maintain order. But obesity can turn these normally protective cells into drivers of chronic inflammation and metabolic disease.

A fifth death connected to West Nile virus was registered Saturday in North Macedonia, which is conducting extensive fumigation against mosquitoes, the country's health authorities said.

Fire and medical officials have issued warnings about a supplement offered to Western wildland firefighters who have been exposed to toxic chemicals while battling some of the country's biggest blazes.

Automatic crash notification (ACN) systems should become a standard safety feature in every new vehicle, like seat belts and airbags, according to a new paper by members of the American College of Surgeons Committee on Trauma (ACS COT), published in the Journal of the American College of Surgeons (JACS). The authors note that ACN is often offered as a premium connected-vehicle service that may stop working when a subscription expires.

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

More than 68,000 men are diagnosed with prostate cancer in the UK each year, a charity says, warning myths may be putting men off getting checked.

Cottage cheese is having a moment. It's being added to dips, mixed into batters and even used in pizza and brownies. It's touted as a high-protein food that can help people build muscle and lose fat.

Climate variability in the Atlantic Ocean can help predict cutaneous leishmaniasis outbreaks in North Africa several months in advance. This is the finding of a new study led by the Barcelona Institute for Global Health (ISGlobal), together with researchers from the Pasteur Institutes of Tunisia, Morocco and France.

Researchers from the University of California San Diego and collaborators have identified a previously overlooked pattern of DNA mutations in colorectal cancer. Scientists use these patterns, known as mutational signatures, to investigate the biological and environmental processes that have damaged DNA during cancer development.
