Stem Cell Mini-Brains Unlock Insights into Autism

Researchers have created "mini-brains" using stem cells from patients with a rare form of autism, allowing them to study brain development in detail. These organoids revealed how a genetic mutation in MEF2C disrupts the balance between excitatory and inhibitory neurons, leading to autism.

Infant Sleep Loss Linked to Brain Development Problems

New research shows that sleep deprivation during early development disrupts brain function, impacting neuron growth and synapse formation. The study found that young mice lacking sleep did not experience the “sleep rebound” seen in adults, leading to lasting deficits in social behavior and memory.

Cannabis Use Linked to Thinner Cortex in Adolescents

Cannabis use in adolescents may lead to thinning of the cerebral cortex, a key brain region for cognitive function. Researchers found that THC, the active ingredient in cannabis, causes the shrinking of dendrites, which are crucial for neuron communication.

Youth Face Rising Risks of Harassment and Exploitation in the Metaverse

A new study reveals that youth are vulnerable to various forms of harm in the metaverse, including bullying, harassment, and sexual exploitation. Using data from over 5,000 U.S. teens, researchers found significant incidents of hate speech, sexual harassment, and grooming behavior in virtual reality (VR) spaces.

Removing Pre-Bed Screen Time Improves Toddler Sleep

A world-first trial shows that eliminating screen time in the hour before bed significantly improves toddlers' sleep quality. The study involved 105 families and found that toddlers who replaced screen time with calming, non-screen activities slept more efficiently and woke up less during the night.

3D Brain Atlas Maps Key Stages of Brain Development

Researchers have created a 3D atlas of the developing mouse brain, offering a dynamic, high-resolution view of brain structures during embryonic and post-natal stages. This new tool allows scientists to explore how brain cells, such as GABAergic neurons linked to neurological disorders, emerge and interact during development.

Parent-Child Play Shapes Social Skills for Interacting with Peers

How parents and toddlers play together can predict children's future social interactions. By observing over 120 mother-child pairs, researchers found that responsive and assertive behaviors during play were linked to better social competence with peers.

Autism Risk in Males Linked to Y Chromosome

New research suggests that the Y chromosome may be responsible for the higher prevalence of autism in males, shifting focus away from protective factors on the X chromosome. Analyzing genetic data, researchers found that individuals with an additional Y chromosome were twice as likely to have an autism diagnosis, while an extra X chromosome had no effect on autism risk.

Folic Acid Reduces Lead’s Impact on Autism Risk

A study has shown that folic acid supplementation during pregnancy may reduce the link between maternal blood lead levels and autistic-like behaviors in children. By examining data from pregnant women and their toddlers, researchers found stronger associations between lead exposure and autism traits in cases of low folic acid intake.

Genetic Influences on Youth Behavior and Mental Health

Researchers have used an innovative approach to explore genetic links to mental health issues in youth, identifying associations with behaviors such as screen time and caffeine consumption. By focusing on polygenic scores that reflect genetic predispositions, the study highlights a range of potentially modifiable factors that may contribute to psychiatric risk.

Human-Specific Genes Reveal Link Between Brain Growth and Autism

Researchers have found a link between two human-specific genes and the gene SYNGAP1, a factor in intellectual disabilities and autism spectrum disorders. These genes, SRGAP2B and SRGAP2C, slow down synapse development, a hallmark of prolonged brain growth thought to enhance learning in humans. By turning off these genes in human neurons, scientists observed accelerated brain connectivity development, mimicking changes seen in certain neurodevelopmental conditions.

Motor Delays May Predict Genetic Disorders in Kids

A recent study reveals that motor delays and low muscle tone are strong indicators of an underlying genetic diagnosis in children with neurodevelopmental disorders. Researchers reviewed patient records to identify early signs, finding that 75% of children with motor delays had genetic diagnoses. Early identification can enable families to seek genetic testing, potentially offering targeted treatments or monitoring for related medical issues.
