It took three sky surveys – conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights – to prepare for a new project that will create the largest 3D map of the universe’s galaxies and glean new insights about the universe’s accelerating expansion.
Researchers have shown that an algorithm with no training in materials science can scan the text of millions of papers and uncover new scientific knowledge. A Berkeley Lab-led team collected 3.3 million abstracts of published materials science papers and fed them into an algorithm. By analyzing relationships between words the algorithm was able to predict discoveries of new thermoelectric materials years in advance and suggest as-yet unknown materials as candidates for thermoelectric materials.
Long ago, during the European Renaissance, Leonardo da Vinci wrote that we humans “know more about the movement of celestial bodies than about the soil underfoot.” Five hundred years and innumerable technological and scientific advances later, his sentiment still holds true. But that could soon change. A new study in Nature Communications details how an improved method for studying microbes in the soil will help scientists understand both fine-grained details and large-scale cycles of the environment.
A new biosynthetic production pathway developed by scientists at the Joint BioEnergy Institute could provide a sustainable alternative to conventional synthetic blue dye. The highly efficient fungi-based platform may also open the door for producing many other valuable biological compounds that are currently very hard to manufacture.
Like a tiny needle in a sprawling hayfield, a single crystal grain measuring just tens of millionths of a meter – found in a borehole sample drilled in Central Siberia – had an unexpected chemical makeup. And a specialized X-ray technique in use at Berkeley Lab confirmed the sample’s uniqueness and paved the way for its formal recognition as a newly discovered mineral: ognitite.
Researchers at Berkeley Lab, in collaboration with Dow and Eindhoven University of Technology, have developed a pulsed electron beam technique that enables high-resolution imaging of magnesium chloride without damage. This approach could apply to a vast range of beam-sensitive materials, and help to create a path toward sustainable plastics.
For years, routine testing has shown that watersheds of the Mahaulepu Valley and Waikomo Stream in southeast Kauai frequently contain high counts of potentially pathogenic fecal indicator bacteria (FIB). To better understand the cause of the high FIB counts, the DOH commissioned a study by Berkeley Lab microbial ecologists Gary Andersen and Eric Dubinsky. After using a powerful microbial detection tool called the PhyloChip, the scientists concluded that most of the past monitoring results were false positives.
Researchers at Lawrence Berkeley National Laboratory have developed a new chemical separation method that is vastly more efficient than conventional processes, opening the door to faster discovery of new elements, easier nuclear fuel reprocessing, and, most tantalizing, a better way to attain actinium-225, a promising therapeutic isotope for cancer treatment.
The overpumping of groundwater in California has led to near environmental catastrophe in some areas – land is sinking, seawater is intruding, and groundwater storage capacity has shrunk. But researchers at Lawrence Berkeley National Laboratory believe machine learning could be part of the solution to restoring groundwater to sustainable levels and quality.
A new electron gun, designed and built at Berkeley Lab to supply electrons for a next-gen X-ray laser, fired its first electrons today. The X-ray laser is part of the LCLS-II project, which is an upgrade of SLAC National Accelerator Laboratory’s Linac Coherent Light Source X-ray laser.
