Tiny, shapeless invaders can find their way from ponds to the human brain and cause an infection so severe that it has a 95% fatality rate. The amoeba Naegleria fowleri naturally lives in ponds, feasting on bacteria, but once it enters the human body, it makes a run for the brain

Tiny, shapeless invaders can find their way from ponds to the human brain and cause an infection so severe that it has a 95% fatality rate. The amoeba Naegleria fowleri naturally lives in ponds, feasting on bacteria, but once it enters the human body, it makes a run for the brain tissue, traversing complex, tight spaces to reach its destination.

Brain cells regulate cholesterol to control neuron signaling

Cholesterol, a fat-like substance in the body best known for its role in cardiovascular health, also plays a key role in how neurons—foundational cells for the brain's ability to process and integrate information—communicate with one another. Now, research led by Vitaly A. Klyach

Vagus Nerve Stimulation Could Help New Skills Stick

Stimulating the vagus nerve after practice helped mice develop stronger long-term motor learning, revealing a potentially important window when the brain is still locking in a new skill. The effect was linked to rhythmic changes in brain blood vessels, hinting that body-to-brain
