An illuminated 3D tour of lower back pain
Back pain affects many people at some point in their lives, and a common cause is damage to the squishy discs or flexible, rubbery tissues of the spine. However, observing this damage at an early stage is difficult with current imaging methods. Now, researchers reporting in ACS Nano can see microscopic soft tissue destruction in...
