They shrink when you heat 'em. Most materials expand when heated, but a few contract. Now engineers at the California Institute of Technology (Caltech) have figured out how one of these curious materials, scandium trifluoride (ScF3), does the trick—a finding, they say, that will lead to a deeper understanding of all kinds of materials.

Xi-Jun Ren and Yang Xiang from Henan Universities in China, in collaboration with Heng Fan at the Institute of Physics of the Chinese Academy of Sciences, have produced a theory for a quantum cloning machine able to produce several copies of the state of a particle at atomic or sub-atomic scale, or quantum state, in an article about to be published in EPJ D . This could have implications for quantum information processing methods used, for example, in message encryption systems.

Physicists from the Georgia Institute of Technology have developed a theory that describes, in a unified manner, the coexistence of liquid and pinned solid phases of electrons in two dimensions under the influence of a magnetic field.

The characteristic crack and bang of a gunshot blast may contain vital clues about a crime: who shot first, or even what type of firearm did the deed. But dozens of factors, from the angle and direction of the gun’s muzzle to the quality of the microphone, can change the way a gunshot sounds in a recording, making it difficult even for expert analysts to tell exactly what went down at the scene of the crime.

Missouri’s digital divide is growing, a trend that threatens to leave farmers and agribusiness ventures at a disadvantage unless federal policymakers make concerted efforts to improve technology infrastructure in rural communities and small towns, according to a new study by the Community Policy Analysis Center (CPAC), located in the Truman School of Public Affairs at the University of Missouri. The study shows that Missouri is significantly behind national averages for overall statewide broadband Internet access.

Engineering researchers at the University of Toronto have developed the world’s most efficient organic light-emitting diodes (OLEDs) on plastic. This result enables a flexible form factor, not to mention a less costly, alternative to traditional OLED manufacturing, which currently relies on rigid glass.
