(Phys.org)—A new type of nanoparticle-based MRI contrast agent demonstrates selectivity for tumor cells over non-cancerous cells, can detect hypoxia, and is sensitive enough allow for the detection of difficult-to-find ...
The remarkable properties of glasses are due to their dynamical arrested state in which relaxations occur on time scales too large to be observed, or so it was believed. Now researchers have discovered the existence of unexpected ...
