A matter of concentration: Molecular mechanisms of water homeostasis

When making a soup, maintaining the correct balance of liquid and salt is key. Similarly, maintaining the balance of water and electrolytes is an important physiological process in the human body, and disruption of this process ...

Human urine-derived stem cells have robust regenerative potential

The Wake Forest Institute for Regenerative Medicine (WFIRM) researchers, who were the first to identify that stem cells in human urine have potential for tissue regenerative effects, continue their investigation into the ...

Cilia-free stem cells offer new path to study rare diseases

A group of rare diseases called "ciliopathies"—polycystic kidney disease notable among them—emerge from defects in cilia, the tiny hair-like structures on the surface of almost every cell type. But the specific molecular-level ...

High protein diet may harm polar bears

A high protein diet appears linked to kidney disease and shortened lifespans for captive polar bears, a relationship similarly suspected in humans, according to a review led by Washington State University wildlife biologist ...
