Social media use has long been part of the everyday lives of most children and adolescents. Many of them exhibit risky, and in some cases even addictive, behaviour. While social media use can certainly have positive effects for young people, intensive use can negatively impact mental, emotional, and social well-being, leading to symptoms such as depression and anxiety, impaired attention, and sleep problems. In a discussion paper published by the German National Academy of Sciences Leopoldina, the researchers involved therefore recommend applying the precautionary principle. In the paper “Social Media and the Mental Health of Children and Adolescents”, they give policy recommendations to protect children and adolescents from the negative effects of social media, for example by setting a minimum age for access or by restricting certain functions. The paper was published on 13 August 2025 and an English translation is now available.

VIB researchers and colleagues have discovered a mechanism through which melanoma cells adapt and switch between two major proliferative and invasive states, revealing promising new targets for cancer therapy. The study, published in Nature Metabolism, reveals that alterations in iron metabolism and organelle crosstalk are central to melanoma cell plasticity—a key factor in tumor progression and resistance to treatment.

Patients in specialised psychiatric care face a variety of social risks that are intertwined, a new study from the University of Eastern Finland shows. Social risks tend to accumulate among the most vulnerable segments of the population. They include for example financial difficulties, housing challenges and violence.

Researchers demonstrated how a multifaceted intervention approach significantly improved the rate of dental varnish applications to help strengthen tooth enamel and prevent decay. The results exceeded the goal for the study, and improvements were consistent across insurance plans, race and ethnicity, providing an important framework for keeping teeth healthy.
