Survivors of high-risk neuroblastoma face substantial late effects of modern therapies

A study published in the Lancet Child and Adolescent Health journal found that high-risk neuroblastoma survivors experience a high prevalence of hearing loss, growth failure, underweight, and lung disease due to modern therapies. Longer follow-up periods were associated with a higher risk of late effects.

Exploring how storytelling strategies shape memories

A new study found that storytelling strategies with conceptual or perceptual details activate distinct brain networks, predicting how well participants recall core elements of the story. This suggests that people's preferred memory systems may vary across age groups, and tailored information could improve memory for older adults.
