Proceedings of the National Academy of SciencesSurprise superconductor Superconductivity is a rare physical state in which matter is able to conduct electricity -- maintain a flow of electrons -- without any resistance. This phenomenon can only be found in certain materials under specific low-temperature and high-pressure conditions. New research found unexpected superconductivity that could help scientists better understand the structural changes that create this rare phenomenon.

Angewandte ChemieChemists work to desalt the ocean for drinking water, 1 nanoliter at a time By creating a small electrical field that removes salts from seawater, chemists have introduced a new method for the desalination of seawater that consumes less energy and is dramatically simpler than conventional techniques. The new method requires so little energy that it can run on a store-bought battery.

Power for seaports may be the next job for hydrogen fuel cells Providing auxiliary hydrogen power to docked or anchored ships may soon be added to the list of ways in which hydrogen fuel cells can provide efficient, emissions-free energy. Hydrogen fuel cells are already powering mobile lighting systems, forklifts, emergency backup systems and light-duty trucks, among other applications. Now, researchers at Sandia National Laboratories have found that hydrogen fuel cells may be both technically feasible and commercially attractive as a power source for ships at berth.

Advanced MaterialsBeyond silicon: Transistors without semiconductors Scientists at Michigan Technological University have built a nanoscale transistor that works at room temperature. The device, only 20 nanometers wide, is made of gold quantum dots mounted on boron nitride nanotubes. It was built in collaboration with colleagues at Oak Ridge National Lab.

Proceedings of the National Academy of SciencesLess is more: Novel cellulose structure requires fewer enzymes to process biomass to fuel Improved methods for breaking down cellulose nanofibers are central to cost-effective biofuel production and the subject of new research from Los Alamos National Laboratory and the Great Lakes Bioenergy Research Center. Scientists are investigating the unique properties of crystalline cellulose nanofibers to develop novel chemical pretreatments and designer enzymes for biofuel production from cellulosic -- or non-food -- plant-derived biomass.

Astronomy & AstrophysicsUnusual supernova is doubly unusual for being perfectly normal Type Ia supernovae are indispensable milestones for measuring the expansion of the universe. With definitive measures of Supernova 2011fe, the "Backyard Supernova" that thrilled amateur and professional astronomers alike in the summer of 2011, the Nearby Supernova Factory led by Lawrence Berkeley National Laboratory demonstrates that this unusually close-by Type Ia is such a perfect example of its kind that future Type Ia's -- and models meant to explain their physics -- must be measured against it.

Advanced MaterialsPrinting tiny batteries Three-dimensional printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.
