Metallic rutile oxides break the rules of cooling
Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, others, like ruthenium dioxide, conduct electricity like a metal. So...

Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, others, like ruthenium dioxide, conduct electricity like a metal. So far, physicists have had little idea of why this happens.
