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.

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.

Fresh urgency in mapping out ethics of brain organoid research

Science is creating new living matter – like stem cells grown to create brain tissues in the lab. With power comes responsibility and what matters is an ethical question, not a scientific one.
The Joint Occupational Health and Safety Committee (JOHSC) of Thompson Rivers University in British Columbia unanimously voted on March 5, 2018 to ban all smoking of marijuana products on campus — for health and safety reasons. (Flickr/Chuck Grimmett)

Marijuana-friendly campuses? I don’t think so …

In advance of marijuana legalization in Canada, one university in British Columbia has taken a firm stance, banning all smoking of cannabis products on campus.

A sudden and lasting separation from a parent can permanently alter brain development

The traumatic separations of children and parents initiated at the border can cause permanent changes in the structure of the infants’ and children’s brains and the activity of their genes.

Living with neighborhood violence may shape teens’ brains

Experiencing and witnessing violence in their communities can lead to emotional, social and cognitive problems for kids. A new study shows it affects how their developing brains grow, as well.

Adult human brains don’t grow new neurons in hippocampus, contrary to prevailing view

The scientists behind a controversial new study were surprised by their own results. But they carefully did all they could to ‘prove a negative,’ and their neurogenesis study is shaking up the field.

How childhood experiences contribute to the education-health link

Adverse childhood events can not only cause lasting psychological effects but also learning problems. That, in turn, worsens health outcomes, as literacy is an integral part of health care.
A 2015 study from the Canadian Centre on Substance Abuse describes youth perceiving marijuana as “relatively harmless” and “not as dangerous as drinking and driving.” (Unsplash/Conor Limkbocker)

Marijuana at school: Loss of concentration, risk of psychosis

Provincial policies to implement the legal consumption of marijuana are unlikely to protect children and youth. High school teachers and parents will be on the front line.
