Omid Kokabee, once a physics graduate student at the University of Texas, Austin, was detained in Iran in 2011. His health has deteriorated severely since being imprisoned, and repeated calls for his release have been unsuccessful.

Adding some erbium ions to the glass in a mircosphere increased the lifetime of a circulating photon from 210 picoseconds to 2.5 milliseconds—that's more than 10 million times longer. An array of such spheres could make a solid-state optical memory.
Introducing a slow-light medium into an optical microresonator extends the lifetime of a photon circulating in the device by several orders of magnitude.

Many nuclei are football-shaped, but only a few have been shown to be pear-shaped. According to new experiments, barium-144 is the newest confirmed member of the club. But its asymmetry is larger than expected, so nuclear structure models may need to be updated.
Experiments confirm that the barium-144 nucleus is pear shaped and hint that this asymmetry is more pronounced than previously thought.

The NOvA experiment sends neutrinos on a 500-mile trip from Fermilab near Chicago to northern Minnesota and looks at the number that change flavor along the way. NOvA's first results provide new constraints (not definitive numbers) for properties of neutrinos and the weak force that physicists are still trying to nail down.
The first results from the NOvA experiment set new constraints on charge-parity violation in neutrinos and on the ordering of neutrino masses.

To re-create the look of old glass mosaics as they restore a Bangkok temple, physicists need to determine the impurities responsible for each color. Red glass turns out to be the most mysterious—how did 19th century craftsmen produce the gold nanoparticles needed for the red color?
Physicists are helping in the restoration of historical glass mosaics at Bangkok’s Temple of the Emerald Buddha.

Some future quantum computers might rely on so-called nitrogen-vacancy (NV) centers in diamond as quantum bits (qubits). Researchers have now demonstrated a new way to change the state of a NV center: vibrational waves on the diamond surface can bump it from the ground state to an excited state.
The state of excited electrons in a diamond-crystal defect can be controlled using mechanical waves.

When describing sand and powders, physicists would like a complete theory like statistical mechanics, which works well for gases. But sand grains don't act enough like molecules for the analogy to work very well. A new approach uses a function based on the network of contacts among the grains as a parameter that is somewhat analogous to energy in statistical mechanics.
A reformulation of the statistical mechanics of granular materials replaces the volume of the material with a function related to its structure.

Game theory may sound frivolous, but it's a serious set of principles for modeling investors or animals competing against each other. Theorists have now shown that the Schrödinger equation, famous from quantum mechanics, also shows up in a class of game theory models, so the tools developed to solve this equation could benefit other areas of research.
Models that treat economic and biological behavior in terms of game-play resemble quantum mechanics.

Working to advance and diffuse the knowledge of physics
Introduction
The American Physical Society (APS) is a non-profit membership organization working to advance and diffuse the knowledge of physics through its outstanding research journals, scientific meetings, and education, outreach, advocacy and international activities. APS represents more than 50,000 members, including physicists in academia, national laboratories and industry in the United States and throughout the world. Society offices are located in College Park, Maryland (Headquarters), Ridge, New York, and Washington, DC.
