Penn 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.

Dusting 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.

New 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.

Scripps 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.

Better 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.

Sea 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.

Penn 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.

Climate 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.

Mice 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.

Researchers 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.

Uncovering 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.

Philadelphia 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.

Endangered 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.
