 LanguagePenn linguistics researchers document Philadelphia's shift to a Northern accent A new study by University of Pennsylvania linguists shows that the Philadelphia accent has changed in the last century. The traditional Southern inflections associated with Philadelphia native-born speakers are increasingly being displaced by Northern influences.

Proceedings of the Academy of Natural Sciences of PhiladelphiaDusting for prints from a fossil fish to understand evolutionary change In 370 million-year-old red sandstone deposits in a highway roadcut, scientists have discovered a new species of armored fish in north central Pennsylvania. Studying and describing this fish's anatomy, they took advantage of a technique that may look like it was stolen from crime scene investigators.

Proceedings of the Academy of Natural Sciences of PhiladelphiaNew fossil species from a fish-eat-fish world when limbed animals evolved Scientists who famously discovered the lobe-finned fish fossil Tiktaalik roseae, a species with some of the clearest evidence of the evolutionary transition from fish to limbed animals, have described another new species of predatory fossil lobe-finned fish fish from the same time and place. By describing more Devonian species, they're gaining a greater understanding of the "fish-eat-fish world" that drove the evolution of limbed vertebrates.

NatureScripps scientists image deep magma beneath Pacific seafloor volcano Since the plate tectonics revolution of the 1960s, scientists have known that new seafloor is created throughout the major ocean basins at linear chains of volcanoes known as mid-ocean ridges. But where exactly does the erupted magma come from? Researchers at Scripps Institution of Oceanography at UC San Diego now have a better idea after capturing a unique image of a site deep in the earth where magma is generated.

Nature CommunicationsBetter than X-rays: A more powerful terahertz imaging system Low-energy terahertz radiation could potentially enable doctors to see deep into tissues without the damaging effects of X-rays, or allow security guards to identify chemicals in a package without opening it. But it's been difficult for engineers to make powerful enough systems to accomplish these promising applications.

Journal of Experimental BiologySea hares outsmart peckish lobsters with sticky opaline Sea hares don't like being eaten. To ward off attacks from peckish lobsters they squirt the attackers with purple ink and a whitish substance called opaline. While we know that ink contains noxious chemicals that are repellent how does opaline work? Charles Derby and colleagues from Georgia State University, USA find out that opaline is so sticky that it gunges up the lobster's antennules effectively plugging their nostrils.

Biosensors and BioelectronicsPenn Researchers attach Lyme disease antibodies to nanotubes, paving way for diagnostic device Existing Lyme disease tests assess the presence of antibodies, which take weeks to form after the initial infection and persist after the infection is gone. Now, a nanotechnology-inspired technique developed by researchers at the University of Pennsylvania may lead to diagnostics that can detect the organism itself.

International Journal of Environmental Research and Public HealthClimate change likely to worsen threat of diarrheal disease in Botswana, arid African countries In a National Science Foundation funded study, Kathleen Alexander, an associate professor of wildlife at Virginia Tech, found that climate drives a large part of diarrheal disease and increases the threat that climate change poses on vulnerable communities. The only study of its kind in Sub-Saharan Africa is based on three decades of historical data and has important implications for arid countries around the world struggling with poverty and increasing health challenges.

Journal of NeuroscienceMice show innate ability to vocalize While humans and birds must learn to vocalize, a Washington State University neurophysiologist has found that deaf male mice will vocalize to females the same way as hearing mice. The finding points the way to a more finely focused, genetic tool for teasing out the mysteries of speech and its disorders.

The Plant CellResearchers find novel way plants pass traits to next generation New research explains how certain traits can pass down from one generation to the next – at least in plants – without following the accepted rules of genetics. Scientists have shown that an enzyme in corn responsible for reading information from DNA can prompt unexpected changes in gene activity – an example of epigenetics.

Zoological Journal of the Linnean SocietyUncovering Africa's oldest known penguins Africa isn't the kind of place you might expect to find penguins. But one species lives in Africa today, and new fossils confirm that as many as four penguin species coexisted on the continent in the past. Exactly why African penguin diversity plummeted is still a mystery, but changing sea levels may be to blame. The fossils represent the oldest evidence of penguins in Africa, predating previously described fossils by 5 to 7 million years.

LanguagePhiladelphia shifts to a Northern accent The traditional Southern inflections associated with the Philadelphia regional accent are increasingly being displaced by Northern influences. A recent study supported by the National Science Foundation documents this trend through an analysis of Philadelphia neighborhood speech patterns over more than a century. The study, "A Hundred Years of Sound Change," to be published in the March 2013 issue of the scholarly journal Language, is authored by University of Pennsylvania linguists William Labov, Ingrid Rosenfelder and Josef Fruehwald.

Ecology and SocietyHomeowner associations can support native species in suburban neighborhoods Although it's known that construction of homes in suburban areas can have negative impacts on native plants and animals, a recent study led by University of Massachusetts Amherst ecologist Susannah Lerman suggests that well- managed residential development such as provided by homeowners associations can in fact support native wildlife.

Museum exhibit developed at Harvard SEAS puts evolution at visitors' fingertips Visitors to the Harvard Museum of Natural History in Cambridge, Mass., and three other US museums can experience and interact with a computerized tabletop exhibit that teaches them about evolution and the history of life on Earth. The result of a three-year project funded by the National Science Foundation, the multitouch surface and programming allow museum visitors to zoom and scroll through the Tree of Life, the immense tree diagram biologists use to represent the evolutionary history of millions of related species.

Proceedings of the National Academy of SciencesDecoding the genetic history of the Texas longhorn Researchers analyzed almost 50,000 genetic markers from 58 cattle breeds. They found that the Longhorn genome traces back through Christopher Columbus' second voyage to the New World, the Moorish invasion of Spain and the ancient domestication of the aurochs in the Middle East and India.

Proceedings of the National Academy of SciencesEndangered lemurs' complete genomes are sequenced and analyzed for conservation efforts For the first time, the complete genomes of three separate populations of aye-ayes -- a type of lemur -- have been sequenced and analyzed in an effort to characterize patterns of genetic diversity and help guide conservation efforts for the species. The aye-aye species is found only on the island of Madagascar in the Indian Ocean and recently was re-classified as "endangered" by the International Union for the Conservation of Nature.
