The secrets of fossil teeth revealed by the synchrotron: A long childhood is the prelude to the evolution of a large brain

Could social bonds be the key to human big brains? A study of the fossil teeth of early Homo from Georgia dating back 1.77 million years reveals a prolonged childhood despite a small brain and an adulthood comparable to that of the great apes. This dis…

How to reduce social media stress by leaning in instead of logging off

Young people’s mental health may depend on how they use social media, rather than how much time they spend using it. Psychology researchers tried an experiment with three groups. They asked one group to stay off social media. They taught another group …

Novel calculator predicts risk of epilepsy after rare stroke

A practical calculator predicts the risk of epilepsy after venous stroke. The aim is to improve care for those affected, which are predominantly young adults.

NeuroMechFly v2: Simulating how fruit flies see, smell, and navigate

Scientists have advanced their NeuroMechFly model, simulating fruit fly movement in the real world. With integrated vision and smell, NeuroMechFly v2 helps us understand brain-body coordination, setting a path for neuroengineering’s role in robotics an…

Early treatment for nerve tumors prevents serious problems, study finds

Small cranial nerve tumors that can cause hearing loss, vertigo and ringing in the ears are often watched rather than treated, but a new study is set to change how the tumors, called vestibular schwannomas, are managed.

‘Emotional contagion’ a factor in seniors’ mental health

A new study finds that seniors who tend to mirror other people’s feelings are more likely to show signs of being anxious or depressed themselves.

Memories are not only in the brain, new research finds

It’s common knowledge that our brains — and, specifically, our brain cells — store memories. But a team of scientists has discovered that cells from other parts of the body also perform a memory function, opening new pathways for understanding how me…

New study challenges social media’s mental health impact

A new study has challenged the perception heavy social media use has a significant impact on mental health, finding little to no relationship between the two. In fact, not only does the research indicate the amount of time spent on social media has a n…

Newly discovered neurons change our understanding of how the brain handles hunger

A new cell type provides a missing piece of the neural network regulating appetite.

What happens in your brain while you watch a movie

By scanning the brains of people while they watched movie clips, neuroscientists have created the most detailed functional map of the brain to date. The fMRI analysis shows how different brain networks light up when participants viewed short clips from…
