How does excess sugar affect the developing brain throughout childhood and adolescence? A neuroscientist who studies nutrition explains

Kids often crave processed sugary foods. But research shows that consuming too many treats during childhood and adolescence may lead to behavioral and emotional problems.

Brain wrinkles and folds matter – researchers are studying the mechanics of how they form

Understanding how brain folding works could help researchers better diagnose and treat neurodevelopmental disorders.

Baby steps: this ancient skull is helping us trace the path that led to modern childhood

Our findings reveal the slowing down of brain development in our ape-like ancestors began more than three million years ago.
Just a few millimeters across, organoids are clumps of cells that resemble the brain. Madeline Andrews, Arnold Kriegstein's lab, UCSF

Brain organoids help neuroscientists understand brain development, but aren’t perfect matches for real brains

Brain organoids are tiny models that neuroscientists use to learn more about how the brain grows and works. But new research finds important differences between the model and the real thing.
The teenage brain has a voracious drive for reward, diminished behavioural control and a susceptibility to be shaped by experience. This often manifests as a reduced ability to resist high-calorie junk foods. (Shutterstock)

How junk food shapes the developing teenage brain

Excessively eating junk foods during adolescence could alter brain development, leading to lasting poor diet habits. But, like a muscle, the brain can be exercised to improve willpower.
Experts have voiced concerns about the uptake of a recent Canadian study, in which water fluoridation was associated with slightly lower IQs in children. (Shutterstock)

Does water fluoridation really damage your children’s IQ?

Community water fluoridation is a cost-effective public health measure that can reduce cavities by approximately 25 per cent. Yet some communities are worried about it.

We scanned one of our closest cousins, the coelacanth, to learn how its brain grows

The discovery of a living coelacanth fish rocked the world in 1939, as scientists thought they had died out with the dinosaurs. A new study illuminates how its skull and tiny brain develop.

Adolescents have a fundamental need to contribute

Teens get a bad rap as selfish, dangerous risk-takers. But neuroscience and psychology research is revising that image: Adolescents are primed to help those around them, with positive benefits for all.
