A team led by researchers at the University of Toronto has found an association between ultra-processed foods in early childhood, and behavioural and emotional development. Specifically, the team found that higher ultra-processed food consumption is linked to behavioural and emotional difficulties including anxiety, fearfulness, aggression or hyperactivity.

The International Society for Stem Cell Research (ISSCR) proudly announces Kyle M. Loh, Stanford University School of Medicine, as the recipient of the 2026 ISSCR Early Career Impact Award, recognizing his transformative contributions to human pluripotent stem cell biology and his exceptional commitment to mentorship and inclusion. The award is supported by the Tianqiao and Chrissy Chen Institute, and Dr. Loh will present his work during ISSCR 2026 taking place on 8-11 July in Montréal, Canada.

A multidisciplinary team wanted to find the best diet to slow tumor growth after a breast cancer diagnosis. Instead, they found one that accelerated it: a high-fat diet. The researchers engineered a tumor model using a human plasmalike medium to re-create a more realistic microenvironment around tumors, and this allowed them to replicate the biochemical effects of nutrients from food. They discovered a high-fat diet accelerates tumor growth and invasion and causes an increase in the enzyme MMP1, which is associated with a poor prognosis.
