Losing Your Hair? You Might Blame the Great Stem Cell Escape.

Every person, every mouse, every dog, has one unmistakable sign of aging: hair loss. But why does that happen?

It is inside the liver that the unique, rich and complex network of immune cells and pathways is set up to decide what is a harmless food […]
