Early Screen Time Linked to Long-Term Brain Changes, Teen Anxiety
Summary: New research following children for more than a decade links high screen exposure before age two to accelerated brain maturation, slower decision-making, and increased anxiety by adolescence. Infants with…
Missing Brain Receptor May Hold the Key to Autism
Summary: Autistic adults show reduced availability of a key glutamate receptor, mGlu5, across widespread brain regions. This difference supports the theory that an imbalance between excitatory and inhibitory signaling may…
Is Your Oral Bacteria Influencing Multiple Sclerosis?
Summary: High levels of the periodontal bacterium Fusobacterium nucleatum may be associated with more severe disability in people with multiple sclerosis. Researchers analyzed tongue-coating samples and found that MS patients…
Working Nights May Increase Cancer Risk
Summary: Chronic circadian disruption — such as night-shift work, irregular schedules, or frequent jet lag — accelerates the development and spread of aggressive breast cancer. Researchers found that disrupted internal…
Emotional Stress Triggers Instant Arousal From Deep Sleep
Summary: A new study uncovers a precise brain pathway that rapidly converts emotional stress into sudden wakefulness during NREM sleep. Researchers found that GABAergic neurons in the BNST activate glutamatergic…
Depression Quietly Damages the Heart Through Stress Circuits
Summary: Depression and anxiety may heighten cardiovascular disease risk through chronic stress pathways in the brain and body. In a large analysis of more than 85,000 adults, those with depression…
Stress Levels Predict Cannabis Use
Summary: New research shows that rats with naturally higher baseline stress hormone levels are significantly more likely to self-administer cannabis vapor. Over several weeks, rats were allowed to nose-poke for…
PTSD Linked to Accelerated Brain Aging
Summary: A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on…
Blocking a Key Protein Greatly Reduces Alzheimer’s Damage
Summary: New findings show that removing Centaurin-α1, a protein elevated in Alzheimer’s disease, significantly reduces inflammation, plaque buildup, and cognitive deficits in a well-established mouse model. Eliminating this protein normalized…
