Vortex laser offers hope for Moore's Law
Like a whirlpool, a new light-based communication tool carries data in a swift, circular motion. Described in a study published July 28, 2016, by the journal Science, the optics advancement could become a central component of next generation computers designed to handle society's growing demand for information sharing. It may also be a salve to those fretting over the predicted end of Moore's Law.

OU physicists developing new systems for next generation solar cells
University of Oklahoma physicists are developing novel technologies with the potential to impact utility-scale energy generation, increase global energy capacity and reduce dependence on fossil fuels by producing a new generation of high efficiency solar cells. The OU team hopes to show that quantum-engineered systems can control thermal losses that restrict the performance of conventional solar cells and harness more of the sun's energy in practical 'hot' carrier solar cells.

New material could advance superconductivity
Scientists have looked for different ways to force hydrogen into a metallic state for decades. Metallic hydrogen is a holy grail for materials science because it could be used for superconductors, materials that have no resistance to the flow of electrons, increasing efficiency many times over. For the first time researchers, led by Carnegie's Viktor Struzhkin, have experimentally produced a new class of materials blending hydrogen with sodium that could alter the superconductivity landscape.

Forests, species on 4 continents threatened by palm oil expansion
As palm oil production expands from Southeast Asia into the Americas and Africa, vulnerable tropical forests and species on four continents face increased risk of loss, a Duke-led study finds. The largest areas of vulnerable forest are in Africa and South America. But because forests in all 20 countries studied contain high concentrations of different mammal and bird species at risk of extinction, conservation efforts need to incorporate localized solutions tailored to each region.

Serendipitous observation may lead to more efficient solar cells and new gas sensors
While investigating perovskite crystals, University of Groningen scientists made an observation that could make perovskite solar cells more efficient. It could also lead to new sensors for oxygen and water vapor. The results were published online by the journal Science Advances on July 27.

Male frogs have sex on land to keep competitors away
Researchers have assumed that natural selection drove frogs to take the evolutionary step to reproduce on land as a way for parents to avoid aquatic predators who feed on the eggs and tadpoles. A new study by a team including Cornell University frog biologists shows for the first time that some frogs hide eggs on land to reduce competition from other males who also want to fertilize those eggs.

Exploring one of the largest salt flats in the world
A recent research report about one of the largest lithium brine and salt deposits in the world in Chile's Atacama Desert by geoscientists from UMass Amherst is the first to show that water and solutes flowing into the basin originate from a much larger than expected portion of the Andean Plateau. The massive evaporite deposit, 1,200 meters thick, appears to be draining an area far larger than a map-based or topographic watershed would suggest, says lead hydrologist David Boutt.
