Watching How Magnetism Unfolds

Physicists have devised a material that allows them to study the birth and evolution of magnetism.  This is analogous to understanding how a caterpillar becomes a butterfly.  Without understanding the key transitional point in its lifecycle, a butterfly just seems to appear fully formed.   For butterflies, we need to discover and study a chrysalis.

Predicting Anomalous Deformation Behavior in Materials

For the first time, researchers can now both explain and predict the behavior of different materials while they are being pulled apart.  Some materials are ductile, meaning they will deform without losing their toughness, and others are brittle.  The results explain even the unexpected and anomalous ductility of a material within a class of rare-earth-containing materials that are otherwise known to be brittle.  To predict the behavior requires two maps.  The first map reveals whether a system has the ability to slip in
