A brain parasite can infect immune cells designed to kill it. Research shows these cells use an enzyme called caspase-8 to self-destruct, killing the parasite and controlling the infection.
New research challenges the habit loop theory of compulsive behavior. In rats, brain inflammation led to more deliberate, goal-driven actions, not habits. This suggests some compulsions involve excessive, misdirected control, not a loss of it.
Scientists created a human spinal cord organoid model that replicates injury effects like cell death and scarring. Testing a "dancing molecules" therapy on it reduced scarring and stimulated nerve regrowth, supporting its potential for human spinal cord injury treatment.
Three approved drugs—a shingles vaccine, Viagra, and riluzole—show promise for repurposing to treat or prevent Alzheimer's, offering a faster, safer path than developing new medications.
The myth that brain development stops at 25 is inaccurate. Research shows the brain, especially the frontal lobe, continues key structural changes into our 30s, with our 20s being a prime time for building efficient neural pathways through learning and challenge.
Michael Pollan's book explores consciousness and how psychedelics reveal it as a brain construct, suggesting the future of intelligence may be understood through its evolution.
Brain connectivity differences between men and women increase at puberty and continue to diverge with age, potentially influencing mental health risks. The study analyzed scans from 1,286 people.
A 300-million-year-old fossil reveals one of the oldest vertebrate herbivores, pushing back the timeline for plant-eating animals. Other news: EU restricts Chinese participation in key research; brain connectivity sex differences grow with age; scientists fight misinformation online.
Correction notice for a Nature article on psychedelics and serotonin receptors, fixing formatting errors, chemical structures, and figure labels.
Brain's venous sinuses are active, not passive. They pump fluid, have holes for immune surveillance, and reshape to accommodate immune cells, showing the brain's borders are highly regulated.
