During chronic stress, immune cells migrate to the brain’s borders and fuel fear responses. psychedelics like psilocybin and MDMA block this immune-brain chatterת calming neurons, but cooling inflammation at the brain's edge.

Teen sleep shapes the brain. A 3,000+ teen study links later bedtimes & short sleep to weaker brain connectivity + lower cognition. Early, longer sleep? Stronger brains & better focus—lasting from age 9 to 14. Link to study: www.cell.com/cell.../full...

New human intracranial data shows that certain thalamic nuclei may initiate awareness before the cortex even kicks in.
This shifts us from the usual “relay station” view of the thalamus, and redraw the map of consciousness.

Slow arterial pumping, powered by norepinephrine waves during deep sleep, drives the brain’s glymphatic system to flush waste. The popular drug Zolpidem might induce sleep but block the cleanse.

Cancer cells transfer mutated mitochondria to T cells—crippling their energy, memory, and function. They also sneaks in USP30 to block cleanup. A mitochondrial Trojan horse that helps explaining tumors resistance to immunotherapy.

New results from the DO-HEALTH trial suggest omega-3s can slow biological aging at the DNA level. Add vitamin D & exercise, and the effects stack up. Measured. Molecular.

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?

Molecule-MCP is a very cool tool connecting PyMOL and ChimeraX directly to Claude through the Model Context Protocol for prompt-assisted molecule modelling. Great stuff by Jinyuan Sun et al

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.

Just 5 days of consuming an extra 1,500 kcal of a daily high-calorie, ultra-processed diet, can disrupt brain insulin signaling, affecting appetite control & metabolism—long after returning to normal eating habits.
