Proceedings of the National Academy of SciencesDinosaur predecessors gain ground in wake of world's biggest biodiversity crisis Newly discovered fossils from 10 million years after Earth's greatest mass extinction reveal a lineage of animals thought to have led to dinosaurs taking hold in Tanzania and Zambia in the mid-Triassic period, many millions of years before dinosaur relatives were seen in the fossil record elsewhere on Earth.

Nature CommunicationsCompeting pathways affect early differentiation of higher brain structures A new study shows how the strength and timing of competing molecular signals during brain development has generated natural and presumably adaptive differences in a brain region known as the telencephalon -- much earlier than scientists had previously believed.

Proceedings of the National Academy of SciencesScientists create novel approach to find RNAs involved in long-term memory storage Scientists from the Florida campus of The Scripps Research Institute, Columbia University and the University of Florida, Gainesville, have developed a novel strategy for isolating and characterizing a substantial number of RNAs transported from the cell-body of neuron (nerve cell) to the synapse, the small gap separating neurons that enables cell to cell communication.

Physics TodayKeeping beverages cool in summer: It's not just the heat, it's the humidity Those drops on the outside of your drink don't just make the can slippery. Experiments show that in hot, humid weather, condensation heats a drink more than the surrounding air.

CellResearchers identify key cellular organelle involved in gene silencing How exactly microRNAs repress target gene expression is not well understood. A team of scientists led by UC Riverside geneticists has conducted a study on plants that shows that the site of action of the repression of target gene expression occurs on the endoplasmic reticulum, a cellular organelle that is an interconnected network of membranes -- essentially, flattened sacs and branching tubules -- that extends like a flat balloon throughout the cytoplasm in plant and animal cells.

Conference on Human Factors in Computing SystemsWith wave of the hand, Carnegie Mellon researchers create touch-based interfaces Researchers previously have shown that a depth camera system, such as Kinect, can be combined with a projector to turn almost any surface into a touchscreen. Now researchers at Carnegie Mellon University have demonstrated how these touch-based interfaces can be created almost at will, with the wave of a hand. CMU's WorldKit system, for instance, enables someone to rub the arm of a sofa to "paint" a remote control for her TV.

SciencePiezoelectric 'taxel' arrays convert motion to electronic signals for tactile imaging Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.

NatureRethinking early atmospheric oxygen Using a quantitative model, a research team of biogeochemists at the University of California, Riverside has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth's history, and its relationship to the sulfur cycle. Their model, the researchers argue, is one step toward a more integrated view of how Earth's crust, mantle and atmosphere interact in the global sulfur cycle.

EcoHealthHumans passing drug resistance to animals in protected Africa, Virginia Tech study says A team of Virginia Tech researchers has discovered that humans are passing antibiotic resistance to wildlife, especially in protected areas where numbers of humans are limited. The research identifies the coupled nature of humans, animals, and the natural environment across landscapes, even those designated as protected.

Philosophical Transactions of the Royal Society BDeep, permeable soils buffer impacts of crop fertilizer on Amazon streams, MBL study finds An MBL study in the fast-changing southern Amazon--a region marked by widespread replacement of native forest by cattle ranches and croplands--suggests that some of the damaging impacts of agricultural fertilization on local streams may be buffered by the deep, highly permeable soils that characterize large areas of the expanding cropland.

NatureAncient Earth crust stored in deep mantle Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth's crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie's Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago.

What's old is new again While automotive and medical device manufacturing may seem unrelated, the latter has benefited from the former. For example, manufacturing techniques developed for increasing the wear resistance of metallic camshafts are routinely used in hip implants. In both applications, performance and reliability are enhanced by increasing the strength of a metal part's surface. Now, an engineer in the Bourns College of Engineering at the University of California, Riverside seeks to extend this concept to medical devices.

Nano LettersNanowires grown on graphene have surprising structure When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy. The self-assembled wires have a core of one composition and an outer layer of another, a desired trait for many advanced electronics applications.

PLOS ONEInsights into deadly coral bleaching could help preserve reefs Coral reefs are stressed because of climate change. Researchers from Northwestern University and The Field Museum of Natural History have discovered corals themselves play a role in their susceptibility to deadly coral bleaching due to the light-scattering properties of their skeletons. No one else has shown this before. Using optical technology designed for early cancer detection, the researchers discovered that reef-building corals scatter light in different ways to the symbiotic algae that feed the corals.
