Scientists say this simple habit could strengthen your marriage

Couples who exercise together report better communication, healthier conflict resolution, and lower marital stress than those who work out alone. Even something as simple as taking a walk together may create valuable opportunities to talk, listen, and feel more connected.

Children at risk for depression get “stuck” on sad faces

Depression may change which emotional faces children notice most, but the pattern appears to depend on family history. Children at higher familial risk became increasingly focused on sad faces, while lower-risk children with rising symptoms paid less attention to happy ones.

Scientists find that “perfect” systems may be surprisingly fragile

Complex systems may work better when their parts are not perfectly alike. Northwestern physicists found that carefully balanced variation, or “disorder,” can make networks such as power grids, ecosystems, neurons, and materials more stable. Even random differences sometimes improved stability compared with completely uniform systems. The discovery could help researchers design more resilient technologies and explain why natural systems are so rarely perfectly uniform.

Hidden brain wiring may help keep the mind sharp as gray matter shrinks

Scientists have discovered that the brain’s short-range wiring may help protect cognition even as gray matter shrinks with age. Healthier connections just beneath the brain’s surface were linked to better language skills and appeared to weaken the impact of gray matter loss.

Scientists say love follows hidden mathematical rules

Could math help explain why some relationships survive life’s inevitable stresses while others slowly fall apart? Researchers have spent decades developing mathematical models that treat romantic feelings as changing systems, revealing patterns in attraction, emotional reactions, conflict, and recovery.

Multilingual people may have brains up to 13 years younger

People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a stronger effect.

MIT neuroscientists discover the brain can reason without words

MIT neuroscientists have found striking evidence that language and logical reasoning are powered by separate systems in the brain. Even people with severe language impairments caused by stroke were able to solve challenging logic puzzles as well as people without those impairments, while brain scans showed that language-processing regions stayed largely quiet during reasoning tasks.
