A study of 236 young adults found that caffeine consumption, especially in the morning, significantly boosts positive mood and enthusiasm. Smaller reductions in sadness were also noted.

Case Western Reserve University scientists have discovered a subset of spinal cord interneurons that boost breathing under stress, such as high CO₂ levels. Blocking these cells impaired respiratory function in mouse models.

Scientists from Mount Sinai and UTEP created a computational model showing how striosomes, a compartment in the brain’s striatum, influence decision-making. High activity can cause impulsivity, while low activity may cause indecision.

Mount Sinai researchers used the Navigation Guide methodology to review 46 studies on prenatal acetaminophen exposure. Higher-quality studies showed a stronger link to autism spectrum disorder and ADHD.

ShanghaiTech University scientists used stem cell-derived brain organoids from familial Alzheimer’s patients to uncover early disease features, including high amyloid levels and reduced neuronal maturity.

A Georgetown University study reveals that left-hemisphere stroke can impair the brain’s ability to use word meanings during reading, particularly when high-imageability words should provide an advantage.

Reactivating factors in mature neurons restores youthful resilience, helping to protect against ALS.

Scientists identified HAR123, a human-accelerated genomic region acting as a transcriptional enhancer that regulates brain cell development. HAR123 influences the balance of neurons and glial cells, potentially enhancing cognitive flexibility.

A UK brain imaging study found that dopamine changes are linked to psychotic symptoms in people with schizophrenia, bipolar disorder or depression. PET scans showed shared and distinct dopamine patterns across diagnoses.

UC Irvine researchers found that women with Down syndrome have more advanced Alzheimer’s pathology than men at the same age of diagnosis. Postmortem brain analysis revealed higher beta amyloid and tau protein levels.
