Bilingual Brains Build Stronger Connections Learning a second language, especially in childhood, can boost brain connectivity and support lifelong cognitive flexibility. New research shows bilingual brains have more efficient networks, benefiting attention and brain health.

Unhealthy Diet Linked to Faster Biological Aging in Young Adults A poor diet may speed up biological aging—even in young adults. New research shows that processed meat, fast food, and sugary drinks accelerate aging, while fruits and vegetables slow it down. What you eat today shapes your future health.

How the Brain Adapts to New Sensory Contexts New research reveals a brain feedback loop that helps adapt to changing sensory information. The olfactory cortex processes both smells and sounds, showing unexpected cross-sensory integration. Could this mechanism also apply to sight and touch?

Blood Test May Predict Postpartum Depression Through Hormone Levels New research suggests postpartum depression may be predicted by hormone levels in late pregnancy. A low pregnanolone/progesterone ratio and high isoallopregnanolone levels may signal increased risk. Early screening could pave the way for preventive treatments.

Oral Bacteria Linked to Stroke Risk New research links Streptococcus anginosus in the gut to higher stroke risk and mortality. Findings suggest oral and gut bacteria may play a key role in stroke prevention. Could better oral hygiene help lower stroke risk?

How Large Social Circles Foster Trust Bigger groups may foster more cooperation, not less! A new study finds that flexible social connections and prosocial instincts help people collaborate effectively, even in large teams. Brain scans show memory and reward centers drive trust-based decisions.

Empathy Peaks in Young Adults Empathy peaks in young adulthood! A new study shows young adults are most sensitive to others' physical & social pain. Older adults show strong brain responses but rate pain less accurately.

Oral Microbiome May Influence Cognitive Decline and Brain Health The oral microbiome may hold the key to brain health. Beneficial bacteria like Neisseria boost cognition, while harmful bacteria link to decline. A nitrate-rich diet could delay cognitive aging.

Study Links Schizophrenia to Visual Contrast Sensitivity Deficits Schizophrenia affects contrast perception, linked to disruptions in glutamate neurotransmission. Could contrast sensitivity testing be a biomarker for diagnosis? https://lnkd.in/gCZyqevj

Mouse With Two Male Parents Survives to Adulthood Scientists create bi-paternal mice by editing imprinting genes, overcoming barriers to unisexual reproduction. Insights could revolutionize regenerative medicine. https://lnkd.in/gc5DgAft
