THE HUMAN BODY
Scientists are discovering hundreds of previously unknown human cell types, suggesting new ways to fight disease.
Your body includes thousands of cell types that scientists know hardly anything about. New technology has revealed a yawning gap in our knowledge about the body, but a global research project is aiming to close it, with more than 1000 scientists working to map our organs. Their discoveries might lead to new treatments against cancer, cystic fibrosis and more.
