BIOMEDICAL ETHICS:
Study of Brain Dead Sparks Debate
Jennifer Couzin
In the February issue of Nature Medicine, researchers report infusing millions of peptides into brain-dead and near-death patients to determine which ones end up in specific tissues. The work has yielded a wealth of data that could not have been obtained otherwise. Although controversial, some ethicists believe that with stringent informed consent procedures, such studies are ethically sound.
