Could a single amino acid change in our genome have nudged us toward language?
New study humanizes the NOVA1 gene in mice—and subtly rewires their vocal behavior.
Is this how speech began?

Babies form memories, but retrieving them later in life is challenging! A new fMRI research shows that by 12 months, hippocampal activity already predicts recognition. This shifts the debate in infants recognition from encoding to retrieval failures. #Neuroscience #InfantileAmnesia #MemoryResearch

Why do women live longer and show greater cognitive resilience in aging? Aging can “reactivate” silent genes on the X chromosome—especially in the hippocampus—boosting brain function. Potential for new cognitive therapies? #AgingResearch #CognitiveResilience #XChromosome #Neuroscience

New research shows that exercise may help protect the brain's white matter by supporting myelin integrity—especially in those with higher levels of 'good' cholesterol (HDL). This may help explain the effect of exercise in MS.
