Berkeley Lab researchers have used a unique optical metamaterial with zero-index refraction to generate phase mismatch–free nonlinear light, an important step towards efficient light generation for future quantum networks and light sources.

Berkeley Lab researchers have discovered a way to introduce a shape memory effect in bismuth ferrite that is larger than any observed in a metal. This discovery opens the door to applications in a wide range of fields, including medical, energy and electronics.

More than two thirds of the world's plants depend on Glomeromycota soil-dwelling symbiotic fungus to survive, including critical agricultural crops such as wheat, cassava, and rice. The analysis of the Rhizophagus irregularis genome, published Nov. 25 in PNAS by French National Institute for Agricultural Research and DOE Joint Genome Institute researchers, has revealed that it doesn't shuffle genes the way researchers expected. Moreover it has expanded its range of cell-to-cell communication genes and phosphorus-capturing genes.

Using a pioneering visualization method, researchers from the UC Berkeley and the Department of Energy Joint Genome Institute made movies of a complex and vital cellular machine called the carboxysome being assembled inside living cells. They observed that bacteria build these internal compartments in a way never seen in plant, animal and other eukaryotic cells. The findings, published Nov. 21, 2013, in the journal Cell, will illuminate bacterial physiology and may also influence nanotechnology development.

A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.

A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for carbon capture and storage.

New results from IceCube, the neutrino observatory buried at the South Pole, may show the way to locating and identifying cosmic accelerators in our galaxy that are 40 million times more powerful than the Large Hadron Collider at CERN.
