Every organ produces waste, and the brain is no exception. But unlike the rest of our body, it doesn’t have a lymphatic system, a network of vessels that filter out junk.

The finding, reported Aug. 15 in Science Translational Medicine, could hint at how diseases like Alzheimer’s develop and might be treated.
