PeterM from Berkeley writes: " This brief from Science Daily reports the claimed detection of magnetic monopoles an emergent property in a crystalline lattice of Dysprosium Titanate at temperatures between
.6K and 2K. According to the article, these magnetic monopoles interact similarly to electrically charged particles. These are not isolated magnetic monopoles in the same sense that electrons are isolated, mobile charges: instead these monopoles appear at the end of tubes of magnetic flux called "Dirac strings". These were theorized in 1931 by Dirac, but have only just now been observed."

PeterM from Berkeley writes: "Scientists are claiming to have made the first practical application of string theory to the problem of high temperature superconductivity, a physical phenomenon no one has previously been able to explain. This brief from Science Daily presents an overview of an article published in Science. String theory has come under fire for producing no testable predictions. This would represent a first application of string theory to a practical problem and one where other theories have provided no explanation."
