JILA team finds first direct evidence of ‘spin symmetry’ in atoms
JILA physicists led by theorist Ana Maria Rey and experimentalist Jun Ye have observed the first direct evidence of symmetry in the magnetic properties—or nuclear “spins”—of atoms. The advance could spin off practical benefits such as the ability to simulate and better understand exotic materials exhibiting phenomena such as superconductivity (electrical flow without resistance) and colossal magneto-resistance (drastic change in electrical flow in the presence of a magnetic field). http://www.colorado.edu/news/releases/2014/08/21/jila-team-finds-first-direct-evidence-%E2%80%98spin-symmetry%E2%80%99-atoms

Bacterial nanowires not what scientists thought they were
For the past 10 years, scientists have been fascinated by a type of “electric bacteria” that shoots out long tendrils like electric wires, using them to power themselves and transfer electricity to a variety of solid surfaces. A team led by scientists at USC has now turned the study of these bacterial nanowires on its head, discovering that the key features in question are not pili, as previously believed, but rather extensions of the bacteria’s outer membrane equipped with proteins that transfer electrons called “cytochromes.”

A chameleon in the physics lab
Looking cooler when heated, a thin coating tricks infrared cameras
Active camouflage has taken a step forward at the Harvard School of Engineering and Applied Sciences (SEAS), with a new coating that intrinsically conceals its own temperature to thermal cameras.

CU-Boulder researchers develop 4D printing technology for composite materials
Researchers at the University of Colorado Boulder have successfully added a fourth dimension to their printing technology, opening up exciting possibilities for the creation and use of adaptive, composite materials in manufacturing, packaging and biomedical applications.
