Two new medical research findings with potentially very important implications in reducing suffering: Researchers Target Mechanism for Cancer Pain, finding a protein that may block some of the bone destruction responsible for the excruciating pain in bone cancer. And Researchers Reduce Transplant Rejection in Mice: by using antibodies against a T-cell surface antigen, they block activation of the T-cells that cause graft-vs.-host disease, a major cause of catastrophic failure of bone marrow transplants.
