Japanese scientists just built human brain circuits in the lab

Researchers in Japan built a miniature human brain circuit using fused stem-cell–derived organoids, allowing them to watch the thalamus and cortex interact in real time. They found that the thalamus plays a decisive role in maturing the cortex and or…

The simplest way teens can protect their mental health

Teens who sleep in on weekends may be giving their mental health a boost. A new study found that young people who made up for lost weekday sleep had a significantly lower risk of depression. While consistent sleep is still best, weekend catch-up sleep …

Why multiple sclerosis slowly steals balance and movement

Many people with multiple sclerosis struggle with balance and coordination, and this study uncovers a hidden reason why. Researchers found that inflammation in the brain disrupts the energy supply of vital movement-controlling neurons. As their mitocho…

Nearly all women in STEM secretly feel like impostors

Nearly all women in STEM graduate programs report feeling like impostors, despite strong evidence of success. This mindset leads many to dismiss their achievements as luck and fear being “found out.” Research links impostorism to worse mental healt…

Brain scans may finally end the guesswork in depression treatment

Researchers compared a traditional Chinese medicine, Yueju Pill, with a standard antidepressant and found both reduced depression symptoms. However, only Yueju Pill increased a brain-supporting protein associated with mood improvement. Brain imaging sh…

Why warm hugs feel so good to your brain

Feeling warm or cold doesn’t just register on the skin—it changes how connected we feel to our own bodies. Research shows that temperature sensations help shape body ownership, emotional regulation, and mental well-being. Disruptions in thermal per…

The hidden timing system that shapes how you think

The brain constantly blends split-second reactions with slower, more thoughtful processing, and new research shows how it pulls this off. Scientists discovered that brain regions operate on different internal clocks and rely on white matter connections…

Scientists discover why mental disorders so often overlap

A massive global genetics study is reshaping how we understand mental illness—and why diagnoses so often pile up. By analyzing genetic data from more than six million people, researchers uncovered deep genetic connections across 14 psychiatric condit…

A hidden brain problem may be an early warning for Alzheimer’s

Researchers discovered that clogged brain “drains” show up early in people at risk of Alzheimer’s disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some …

A "herculean" genetic study just found a new way to treat ADHD

Attention depends on the brain’s ability to filter out distractions, but new research suggests this works best when background brain activity is quieter. Scientists found that lowering certain versions of the Homer1 gene improved focus in mice by cal…
