The unifying framework of symmetry reveals properties of a broad range of physical systems
Symmetry is one of the most fundamental concepts in nature, and it can give rise to profound and wide-reaching physical effects. A one-dimensional wire, for example, has a different symmetry and very different mechanical properties to those of a two-dimensional sheet of the same material. Tomoya Hayata and Yoshimasa Hidaka from the RIKEN Nishina Center for Accelerator-Based Science have now studied the consequences of breaking symmetry for various systems found in nature, providing a powerful, general framework to describe the link between properties and symmetries.

What time is it in the universe?
Flavor Flav knows what time it is. At least he does for Flavor Flav. Even with all his moving and accelerating, with the planet, the solar system, getting on planes, taking elevators, and perhaps even some light jogging. In the immortal words of Kool Moe Dee. Do you know what time it is?

Experiments reveal a neutron halo around neutron-rich magnesium nuclei
Most stable atomic nuclei are made up of roughly an equal number of protons and neutrons. With the right equipment, however, physicists can create nuclei with many additional neutrons. These neutron-rich nuclei are short-lived but represent an important tool for developing a better understanding of how the elements in the Universe were created.

Watching the structure of glass under pressure
Glass has many applications that call for different properties, such as resistance to thermal shock or to chemically harsh environments. Glassmakers commonly use additives such as boron oxide to tweak these properties by changing the atomic structure of glass. Now researchers at the University of California, Davis, have for the first time captured atoms in borosilicate glass flipping from one structure to another as it is placed under high pressure.

Pioneer strategy for creating new materials
Making something new is never easy. Scientists constantly theorize about new materials, but when the material is manufactured it doesn't always work as expected. To create a new strategy for designing materials, scientists combined two different approaches at two different facilities to synthesize new materials. This new strategy gives faster feedback on what growth schemes are best, thus shortening the timeframe to manufacture a new, stable material for energy transport and conversion applications.

Breakthrough in light sources for new quantum technology
One of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons (electronic circuits). First, it is necessary to create a stream of single photons and control their direction. Researchers have now succeeded in creating a steady stream of photons emitted one at a time and in a particular direction.
