AI Maps the Brain’s Hidden Bridge, Revealing Genetic Links to Mental Health

For the first time, scientists have mapped the genetic architecture of the brain’s communication bridge—the corpus callosum—using AI and MRI data from over 50,000 people. The study uncovered dozens of genes that shape this vital structure’s size and thickness, many active during prenatal development when the brain’s wiring is established.

BrainSTEM Atlas Maps Every Cell of the Developing Human Brain

Scientists have built one of the most comprehensive single-cell maps of the developing human brain. The new BrainSTEM framework analyzed nearly 680,000 fetal brain cells to chart their growth and interactions, offering a detailed reference for studying neuron development.

Your Brain Knows a Viral Message Before You Do

A large-scale brain imaging analysis reveals that our brains can forecast what kinds of messages will go viral. Researchers found that persuasive messages consistently activate brain regions associated with reward, empathy, and social understanding, predicting both personal preferences and public appeal. Interestingly, while emotional brain activity predicted message success in larger audiences, it did not in individuals who were scanned.

Antioxidant Defense System in the Brain Discovered

A new study identifies biliverdin reductase A (BVRA) as a crucial enzyme defending neurons from oxidative stress, acting independently of its traditional role in bilirubin production. Using genetically modified mice, researchers found that BVRA binds directly to NRF2, a master regulator of antioxidant defense, ensuring the activation of protective genes that maintain cellular health.

Long-Term Melatonin Use Linked to Higher Heart Failure Risk

A large-scale analysis of more than 130,000 adults with chronic insomnia found that long-term melatonin use—defined as one year or more—was associated with a striking increase in heart failure, hospitalization, and mortality risk. Using global health records, researchers found that melatonin users had about 90% higher odds of developing heart failure and were nearly twice as likely to die from any cause within five years.

Why Warm-Blooded Animals Evolved the Biggest Brains

A global study of vertebrates reveals that body temperature is the key driver behind brain size evolution. Warm-blooded species like mammals and birds can maintain the energy demands of larger brains, while cold-blooded species are limited by fluctuating external temperatures.

Brain Circuit Found to Shape Risk and Impulse Differently by Sex

Researchers exploring risky decision-making in rats found that a specific reward-related neural circuit influences impulsivity and risk-taking in complex ways that depend on timing and biological sex. Manipulating the circuit during the learning phase of a gambling task altered risky choices differently in males and females, while manipulation after learning affected motor impulsivity in both.

Losing Sleep Might Make You Hungrier and Sleepier Later

New research using fruit flies reveals that sleep loss can trigger both increased eating and sleeping—if the deprivation leads to energy depletion. Flies that lost energy while sleep-deprived compensated with extra rest and food intake, while those deprived without losing energy showed no such rebound.

Why Kids Still Struggle With Capital Letters After Grade School

New research reveals that English-speaking children continue to refine their capitalization skills well past the early grades, despite being taught the rules early. Across two studies, students in Grades 3–6 made more errors than older students and relied more heavily on having “two clues”—such as a proper noun at the start of a sentence—to capitalize correctly.

Don’t Ignore the Winter Blues, It Could Be Seasonal Depression

As daylight fades, many experience fatigue or low mood—but for millions, these symptoms signal seasonal affective disorder (SAD), a serious form of depression. Reduced sunlight disrupts serotonin, melatonin, and the body’s circadian rhythm, leading to feelings of hopelessness, loss of interest, and sleep or appetite changes.

How Chocolate’s Puckering Taste May Stimulate the Brain

Japanese researchers have uncovered how the astringent “bite” of cocoa flavanols can activate the brain—even though little of the compound enters the bloodstream. In mice, the sensation of astringency triggered sensory nerves that stimulated neurotransmitters linked to motivation, alertness, and memory.

Rotating Brain Waves Help the Mind Refocus After Distraction

Neuroscientists have discovered that when the brain is distracted, coordinated “rotating” waves of neural activity help it steer back to focus. Using electrical recordings in animals, the team found that neurons in the prefrontal cortex synchronize in circular patterns—like starlings in flight—to recover from cognitive interruptions.
