Expanding when it shouldn't: New material with exceptional negative compressibility

Our intuition tells us that a sample of material compressed uniformly from all sides should reduce its dimensions. Only a few materials subjected to hydrostatic compression exhibit the opposite behavior, expanding slightly in one or two directions. A new material has now been discovered with exceptionally high negative compressibility and a previously unknown mechanism responsible for it.
