Leg exercise is critical to brain and nervous system health

New research shows that using the legs, particularly in weight-bearing exercise, sends signals to the brain that are vital for the production of healthy neural cells. The groundbreaking study fundamentally alters brain and nervous system medicine — giving doctors new clues as to why patients with motor neuron disease, multiple sclerosis, spinal muscular atrophy and other neurological diseases often rapidly decline when their movement becomes limited.

Insight into blood signatures of inflammation

A new study identifies a pattern of inflammation associated with cardio-metabolic risks among participants in the Black Women’s Health Study, as well as two independent groups of vulnerable women. These findings could help under-served patients benefit from precision medicine and personalized profiles of disease risk.

Exercise could make the heart younger: Mice make over four times as many new heart muscle cells when they exercise

After a heart attack, patients must create new heart muscle cells to heal. A new study shows that mice make more new heart muscle cells when they exercise compared to when they do not. This was true for both healthy mice and those that had experienced a heart attack. Findings demonstrate that one reason exercise is beneficial to health is that it increases the heart’s capacity to regenerate.
