(Medical Xpress)—Two groups of researchers working on two different projects have made inroads into understanding the cause of alopecia—the gradual loss of hair during aging. One team, with members from Japan, the U.S. ...
Some nerve cells in the inner ear can signal tissue damage in a way similar to pain-sensing nerve cells in the body, according to new research from Johns Hopkins. If the finding, discovered in rats, is confirmed in humans, ...
