NEES Quake Summit 2013Simulations aiding study of earthquake dampers for structures Researchers have demonstrated the reliability and efficiency of "real-time hybrid simulation" for testing a type of powerful damping system that might be installed in buildings and bridges to reduce structural damage and injuries during earthquakes.

Santa's workshop not flooded -- but lots of melting in the Arctic Widespread media reports of a lake at the North Pole don't hold water -- but scientists who deployed the monitoring buoys are watching closely as Arctic sea ice approaches its yearly minimum.

 Applied Physics LettersRensselaer researchers identify cause of LED 'efficiency droop' Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called "efficiency droop" that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to greater electrical currents.

Behavioral Ecology and SociobiologyVeeries very quiet when owls are about If you hear an owl hooting at dusk, don't expect to catch the flute-like song of a Veery nearby. This North American thrush has probably also heard the hoots, and is singing much less to ensure that it does not become an owl's next meal. A new study, published in Springer's journal Behavioral Ecology and Sociobiology, provides insights into just how eavesdropping between predators and prey around dusk may be shaping communication in birds.

Palaeogeoraphy, Palaeocilmatology, PalaeoecologyIce-free Arctic winters could explain amplified warming during Pliocene Year-round ice-free conditions across the surface of the Arctic Ocean could explain why the Earth was substantially warmer during the Pliocene Epoch than it is today, despite similar concentrations of carbon dioxide in the atmosphere, according to new research carried out at the University of Colorado Boulder.

Ceramics InternationalNew coating may help joint replacements bond better with bone Researchers have found that bone cells grow and reproduce faster on a textured surface than they do on a smooth one -- and they grow best when they can cling to a microscopic shag carpet made of tiny metal oxide wires.

Proceedings of the National Academy of SciencesNatural affinities -- unrecognized until now -- may have set stage for life to ignite The chemical components crucial to the start of life on Earth may have primed and protected each other in never-before-realized ways, according to new research. It could mean a simpler scenario for how that first spark of life came about on the planet.

Physical Review LettersExperimental quest to test Einstein's speed limit Special relativity states that the speed of light is the same in all frames of reference and that nothing can exceed that limit. UC Berkeley physicists used a novel experimental system -- the unusual electron orbitals of dysprosium -- to test whether the maximum speed of electrons follows this rule. The answer is yes, to tighter limits than ever before. They plan another experiment a thousand times more sensitive, approaching the realm where theory may break down.

Binghamton University study aims to improve dyslexia treatment Neuroscientist Sarah Laszlo wants to understand what's going on in children's brains when they're reading. Her research may untangle some of the mysteries surrounding dyslexia and lead to new methods of treating America's most common learning disorder.

Proceedings of the National Academy of SciencesHow does hydrogen metallize? Hydrogen is deceptively simple. It has only a single electron per atom, but it powers the sun and forms the majority of the observed universe. As such, it is naturally exposed to the entire range of pressures and temperatures available in the whole cosmos. But researchers still struggle to understand even basic aspects of its various forms under high-pressure conditions. New work makes significant additions to our understanding of this vital element's high-pressure behavior.

Nature NanotechnologyMolecular robots can help researchers build more targeted therapeutics Many drugs such as agents for cancer or autoimmune diseases have nasty side effects because while they kill disease-causing cells, they also affect healthy cells. Now a new study has demonstrated a technique for developing more targeted drugs, by using molecular "robots" to hone in on more specific populations of cells.

Hydrology and Earth System SciencesGlobal warming to cut snow water storage 56 percent in Oregon watershed A new report projects that by the middle of this century there will be an average 56 percent drop in the amount of water stored in peak snowpack in the McKenzie River watershed of the Oregon Cascade Range -- and that similar impacts may be found on low-elevation maritime snow packs around the world.

Proceedings of the National Academy of SciencesComputer can infer rules of the forest Cornell researchers have devised a computer algorithm that takes intermittent samples -- for example, the number of prey and predating species in a forest once a year, or the concentration of different species in a chemical bath once an hour -- and infer the likely reactions that led to that result. They're working backward from traditional stochastic modeling, which they say could help unravel the hidden laws in fields as diverse as molecular biology to population ecology to basic chemistry.

Nature MethodsBroad-scale genome tinkering with help of an RNA guide Duke researchers have devised a way to quickly and easily target and tinker with any gene in the human genome. The new tool, which builds on an RNA-guided enzyme they borrowed from bacteria, is being made freely available to researchers who may now apply it to the next round of genome discovery.

Nano LettersNYU-Poly nano scientists reach holy grail in label-free cancer marker detection: Single molecules Just months after setting a record for detecting the smallest single virus in solution, researchers at the Polytechnic Institute of New York University announced a new breakthrough: A nano-enhanced version of their biosensor detected a single cancer marker protein and even smaller molecules below the mass of all known markers. This achievement sets a new benchmark for the most sensitive limit of detection, and may significantly advance early disease diagnostics.

Journal of American Chemical SocietyCarnegie Mellon biophysicist obtains first experimental evidence of pressure inside the herpes virus Scientists have long suspected that herpes viruses were packaged so full of genetic material that they built up an internal pressure so strong it could shoot viral DNA into a host cell during infection. Carnegie Mellon University and University of Pittsburgh researchers have measured, for the first time, the pressure inside human herpes simplex virus 1. The study, published online in the Journal of the American Chemical Society, establishes a new target for antiviral therapies.

The Astrophysical JournalSolar system's youth gives clues to planet search Comets and meteorites contain clues to our solar system's earliest days. But some of the findings are puzzle pieces that don't seem to fit well together. A new set of theoretical models from Carnegie's Alan Boss shows how an outburst event in the Sun's formative years could explain some of this disparate evidence. His work could have implications for the hunt for habitable planets outside of our solar system.

NatureStarburst wind keeps galaxies 'thin' Unlike humans, galaxies don't have an obesity problem. In fact there are far fewer galaxies at the most massive end of the galactic scale than expected and scientists have long sought to explain why. A new, UMD-led study published in the journal Nature suggests that one answer lies in a kind of feast and fast sequence through which large galaxies can keep their mass down.

Scientific ReportsCoastal Antarctic permafrost melting faster than expected Scientists have documented an acceleration in the melt rate of permafrost in a part of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic and could preview melting permafrost in other parts of a warming Antarctica. In Garwood Valley, scientists found melt rates accelerated consistently from 2001 to 2012, rising to about 10 times the historical average.
