First in-situ images of void collapse in explosives
While creating the first-ever images of explosives using an x-ray free electron laser in California, Los Alamos researchers and collaborators demonstrated a crucial diagnostic for studying how voids affect explosives under shock loading. The in situ data constitute the first experimental step toward developing next-generation, physically based mesoscale models with predictive capability for high explosives.

The first supercomputer simulations of 'spin–orbit' forces between neutrons and protons in an atomic nucleus
Protons and neutrons are held together at the center of an atom by powerful nuclear forces. A theory that can describe the interaction between just two of these subatomic particles could potentially be extended to predict the existence and properties of more exotic particles, but simulations of such systems using conventional approaches are computationally intensive and have been hampered by a lack of available computing power.

Breakthrough laser experiment reveals liquid-like motion of atoms in an ultra-cold cluster
A new study by researchers from the University of Leicester has furthered our understanding of how tiny nanosystems function, unlocking the potential to create new materials using nanosized 'building blocks'.

By measuring infrared emissivity, work is being done to improve the features of solar thermal collectors
Researchers in the UPV/EHU's department of Condensed Matter Physics have developed the only infrared emissivity radiometer existing in Spain. The university is also one of the few centres worldwide that have this kind of device. Many research centres and companies have taken advantage of this possibility and collaboration has been set up with this research group to obtain absolute, reliable measurements of the emissivity of their materials, tools or components. In the most recent collaboration they have participated in, they have been working to improve the efficiency of solar collectors.

Unleashing the power of quantum dot triplets
Another step towards faster computers relies on three coherently coupled quantum dots used as quantum information units. Quantum computers have yet to materialize. Yet, scientists are making progress in devising suitable means of making such computers faster. One such approach relies on quantum dots-a kind of artificial atom, easily controlled by applying an electric field. A new study demonstrates that changing the coupling of three coherently coupled quantum dots (TQDs) with electrical impulses can help better control them.

Spinach could lead to alternative energy more powerful than Popeye
Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Physicists are using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun's energy into carbohydrates used to power cellular processes. Artificial photosynthesis could allow for the conversion of solar energy into renewable, environmentally friendly hydrogen-based fuels.
