Researchers find new target for disease of the heart's smallest blood vessels

When we race walk, for example, part of our healthy heart muscle may want a little more blood and oxygen, so our tiniest blood vessels send a message upstream to the larger vessels to send more.

Study reveals surprising discoveries about poorly understood glioblastoma

Glioblastoma, a cancer that arises in the brain's supporting glial cells, is one of the worst diagnoses a child can receive. The grade IV, highly malignant tumor aggressively infiltrates healthy brain tissue, and most children die of the disease within one to two years of diagnosis, similar to adults.
