It's go time for LUX-Zeplin dark matter experiment
From the physics labs at Yale University to the bottom of a played-out gold mine in South Dakota, a new generation of dark matter experiments is ready to commence. The US Department of Energy's Office of Science and the National Science Foundation recently gave the go-ahead to Large Underground Xenon-Zeplin, a key experiment in the hunt for dark matter, the invisible substance that may make up much of the universe.

Metal particles in solids aren't as fixed as they seem, new memristor study shows
In work that unmasks some of the magic behind memristors and 'resistive random access memory,' or RRAM -- cutting-edge computer components that combine logic and memory functions -- researchers have shown that the metal particles in memristors don't stay put as previously thought.

Protons power protein portal to push zinc out of cells
Researchers at The Johns Hopkins University report they have deciphered the inner workings of a protein called YiiP that prevents the lethal buildup of zinc inside bacteria. They say understanding YiiP's movements will help in the design of drugs aimed at modifying the behavior of ZnT proteins, eight human proteins that are similar to YiiP, which play important roles in hormone secretion and in signaling between neurons.

Family of proteins plays key role in cellular pump dynamics
Case Western Reserve University scientists have discovered how a family of proteins -- cation diffusion facilitators -- regulates an important cellular cycle where a cell's energy generated is converted to necessary cellular functions. The finding has the potential to inform future research aimed at identifying ways to ensure the process works as designed and, if successful, could lead to significant breakthroughs in the treatment of Parkinson's, chronic liver disease and heart disease.

PARC wins renewed funding for photosynthetic research
The Department of Energy has awarded the Photosynthetic Antenna Research Center $14.4 million for continuing research on natural and bio-inspired systems for harvesting the sun's energy. The center, which is hosted by Washington University in St. Louis, was one of 32 projects selected for funding from among more than 200 proposals and one of only 22 to receive second-round funding.

Familiar yet strange: Water's 'split personality' revealed by computer model
Using computer models, Princeton University researchers found that as water freezes it takes on a sort of split personality wherein, at very cold temperatures and above a certain pressure, it may spontaneously split into two liquid forms. Finding this dual nature could lead to a better understanding of how water behaves in high-altitude clouds, which could improve the predictive ability of current weather and climate models.

Crowdsourcing the phase problem
Compared with humans, computers have the capacity to solve problems at much greater speed. There are many problems, however, where computational speed alone is insufficient to find a correct or optimal solution.

Protein could put antibiotic-resistant bugs in handcuffs
A team from Duke and the University of Sydney has solved the structure of a key protein that drives DNA copying in the plasmids that make staphylococcus bacteria antibiotic resistant. Knowing how this protein works may now help researchers devise new ways to stop the plasmids from spreading antibiotic resistance in staph by preventing the plasmids from copying themselves.

A new look at old forests
As forests age, their ability to grow decreases, because energy production (photosynthesis) and energy consumption (respiration) decrease with age, a new study by Marine Biological Laboratory scientists and colleagues has determined. Since most US forests are maturing from regeneration that began about 100 years ago when extensive clear-cutting occurred, the study suggests the future growth of US forests will decline.

New UGA research engineers microbes for the direct conversion of biomass to fuel
The promise of affordable transportation fuels from biomass -- a sustainable, carbon neutral route to American energy independence -- has been left perpetually on hold by the economics of the conversion process. Research from the University of Georgia has overcome this hurdle allowing the direct conversion of switchgrass to fuel. The study, in the Proceedings of the National Academy of Sciences, documents the direct conversion of biomass to biofuel without pre-treatment, using the engineered bacterium Caldicellulosiruptor bescii.

NIST chip produces and detects specialized gas for biomedical analysis
A chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging has been built and demonstrated at NIST. The new microfluidic chip produces magnetized xenon gas and then detects even the faintest magnetic signals from the gas. Magnetized xenon can be used as a marker for detecting biomolecules in liquids. Conventional systems for producing and using this gas can be as big as a car.
