Scientists found an early depression clue hidden in children’s eyes

Depression appears to change what children notice in the faces around them, but the effect depends on family history. Kids with a higher inherited risk became more focused on sadness, while lower-risk children lost some of their natural attention to happy expressions.

Scientists discover gut bacteria that may help protect against autism and ADHD

A major study suggests that some of the groundwork for brain development may be shaped before birth through a surprising partnership between a baby’s genes and gut microbes. Researchers found that epigenetic changes present at birth can influence how the gut microbiome develops during the first year of life, and certain combinations were linked to early signs of autism and ADHD by age three.

Think you’re bad at languages? Experts say these 5 myths are to blame

Many people avoid learning a new language because they remember stressful grammar lessons or fear making mistakes. But language experts say communication, culture, and connection matter far more than perfection. Modern apps, entertainment, travel, and online communities have made learning easier, more social, and surprisingly fun.

Artificial neurons successfully communicate with living brain cells

Engineers at Northwestern University have taken a striking leap toward merging machines with the human brain by printing artificial neurons that can actually communicate with real ones. These flexible, low-cost devices generate lifelike electrical signals capable of activating living brain cells, a breakthrough demonstrated in mouse brain tissue.

Scientists link childhood stress to lifelong digestive issues

Early life stress may set the stage for long-term digestive problems by disrupting the gut-brain connection. Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different biological pathways control different gut issues, hinting at more personalized treatments in the future. The research also highlights how a child’s early environment can have lasting physical effects—not just emotional ones.

Intelligence emerges when the whole brain works as one

For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks — yet one big mystery remained: why does the mind feel like a single, unified system? Researchers at the University of Notre Dame now suggest that intelligence doesn’t live in one “smart” region of the brain at all. Instead, it emerges from how efficiently and flexibly the brain’s many networks communicate and coordinate with each other.

Scientists reveal why human language isn’t like computer code

Human language may seem messy and inefficient compared to the ultra-compact strings of ones and zeros used by computers—but our brains actually prefer it that way. New research reveals that while digital-style encoding could theoretically compress information more tightly, it would demand far more mental effort from both speaker and listener. Instead, language is built around familiar words and predictable patterns that reflect our real-world experiences, allowing the brain to constantly anticipate what comes next and narrow down meaning step by step.
