Decoding the neighborhood dynamics of childhood brain cancer

New research published in Nature finds that tumor cells within supratentorial ependymomas (SE) – an aggressive childhood brain cancer – cluster into distinct tumor cell populations. Much like a neighborhood in your hometown, each cell subtype within these "communities" has a specific (and previously unappreciated) role to play.

Study finds toddlers who eat more ultra-processed foods show slightly higher behavioral symptoms

A prospective analysis of 2,077 children in the Canadian CHILD Cohort Study found that higher intake of ultra-processed foods at age three was associated with slightly higher behavioral and emotional symptom scores by age five. Modeling showed that replacing 10% of calories from ultra-processed foods with minimally processed foods was associated with modestly lower symptom scores.
