Changes in connectivity could help doctors choose the best therapies.

After a stroke, the brain suffers more broadly than just at the spot that was starved of blood. New research, which uses brain imaging to examine connections between different parts of the brain, shows that communication between the left and right hemispheres is often disrupted; the greater the disruption, the more profound the patient's impairment in movement or vision. Researchers hope to use the approach to predict which patients are mostly likely to recover on their own and which will need the most intensive therapy.

A number of dual-action antibodies are in clinical trials for fighting cancer.

Last year marked a first for engineered antibodies--the European Commission approved a new cancer drug called Removab (catumaxomab), an antibody specially designed to grab both cancer cells and immune cells in such a way that the immune cell can kill the cancer cell. (The drug is undergoing testing for U.S. Food and Drug Administration approval.)
