By bombarding the material with low-energy protons, scientists doubled the amount of current the material could carry without resistance, while raising the temperature at which this superconducting state emerges.
Berkeley Lab researchers have compiled a comprehensive genome-wide map of more than 80,000 enhancers considered relevant to human heart development and function. They went on to test two of the enhancers in mice, showing that when the enhancers were missing, the heart worked abnormally.
A better understanding of how bacteria fix nitrogen gas into nitrogen-carrying ammonia could lead to energy savings in industrial processes. Researchers are studying the bacterial enzyme that does this, a complicated enzyme called nitrogenase. In new work, researchers discovered that the two sides of nitrogenase cooperate in producing ammonia, alternating through different steps in a way that makes efficient use of the complex enzyme.
When the local water management agency closes your favorite beach due to unhealthy water quality, how reliable are the tests they base their decisions on? As it turns out, those tests, as well as the standards behind them, have not been updated in decades. Now scientists from Lawrence Berkeley National Laboratory have developed a highly accurate, DNA-based method to detect and distinguish sources of microbial contamination in water.

DOE's Argonne National Laboratory, Colorado-based Air Squared, Inc., Mississippi State University and Purdue University launched efforts to develop the first residential CHP system that uses small generators. The group's proposal to optimize combined heating and power systems (CHP) for residential housing earned $2.7 million in seed money in October from the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E).
Structural biology research conducted at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory has uncovered how small insecticidal protein crystals that are naturally produced by bacteria might be tailored to combat dengue fever and the Zika virus.
Scientists at the U.S. Department of Energy's Ames Laboratory, in collaboration with several partners, have discovered a less-expensive, more energy-efficient way to produce alane - aluminum trihydride - a hydrogen source widely considered to be a technological dead-end for use in automotive vehicles.
A self-powered fish-tracking tag uses a flexible strip containing piezoelectric materials to emit tiny beeps that are recorded by underwater microphones. The device is designed for longer-living fish such as sturgeon, eels and lamprey.
A team of scientists studying solar cells made from cadmium telluride, a promising alternative to silicon, has discovered that microscopic "fault lines" within and between crystals of the material act as conductive pathways that ease the flow of electric current. This research-conducted at the University of Connecticut and the U.S. Department of Energy's Brookhaven National Laboratory, and described in the journal Nature Energy-may help explain how a common processing technique turns cadmium telluride into an excellent material for transforming sunlight into electricity, and suggests a strategy for engineering more efficient solar devices that surpass the performance of silicon.
In order to discover the true colors of ancient animals, scientists are using X-rays to closely examine the chemical details of modern bird feathers. The researchers were able to map elements that make up pigments responsible for red and black colors in feathers. They hope to use this information to find traces of the same pigments in fossil specimens of extinct animals, such as dinosaurs. This latest discovery means that scientists may be able to go beyond monochrome in their depictions of fossilized creatures, and make steps towards portraying their colors more accurately.
Researchers observed, for the first time, an exotic 3-D racetrack for electrons in ultrathin slices of a crystal they made at Berkeley Lab.
The coupling between electrons and phonons determines how efficiently solar cells convert sunlight into electricity. It also plays key roles in superconductors that transfer electricity without losses, topological insulators that conduct electricity only on their surfaces, materials that drastically change their electrical resistance when exposed to a magnetic field, and more. At the Department of Energy's SLAC National Accelerator Laboratory, scientists can study these coupled motions in unprecedented detail with the world's most powerful X-ray laser, the Linac Coherent Light Source (LCLS). LCLS is a DOE Office of Science User Facility.
In a new study by researchers at the U.S. Department of Energy's Argonne National Laboratory, scientists noticed that magnetic skyrmions - small electrically uncharged circular structures with a spiraling magnetic pattern - do get deflected by an applied current, much like a curveball gets deflected by airflow.
Elementary school science teaches us that in the sun, dark colors get hot while white stays cool. Now new research from Lawrence Berkeley National Laboratory has found an exception: scientists have determined that certain dark pigments can stay just as cool as white by using fluorescence, the re-emission of absorbed light.
Scientists have successfully paired ferroelectric and ferrimagnetic materials so that their alignment can be controlled with a small electric field at near room temperatures, an achievement that could open doors to ultra low-power microprocessors, storage devices and next-generation electronics.
