PHILADELPHIA — In a study of the harsh but beautiful White Sands National Monument in New Mexico, University of Pennsylvania researchers have uncovered a unifying mechanism to explain dune patterns. The new work represents a contribution to basic science, but the findings may also hold implications for identifying when dune landscapes like those in Nebraska’s Sand Hills may reach a “tipping point” under climate change, going from valuable grazing land to barren desert.
PHILADELPHIA — Geological evidence of earthquakes and tsunamis aids in anticipating the timing and magnitude of future events. This natural warning system now influences building codes and planning in the United States, Canada and Japan, particularly where the geological record demonstrates prehistoric earthquakes larger than those known from written and instrumental records.

Gene Therapy Research Team From Penn Vet and Scheie Eye Institute Cures Retinitis Pigmentosa in Dogs
PHILADELPHIA -- Members of a University of Pennsylvania research team have shown that they can prevent, or even reverse, a blinding retinal disease, X-linked Retinitis Pigmentosa, or XLRP, in dogs.
The disease in humans and dogs is caused by defects in the RPGR gene and results in early, severe and progressive vision loss. It is one of the most common inherited forms of retinal degeneration in man.
PHILADELPHIA — More than 17 million Americans 65 or older have at least one firearm. Based on the current patterns of gun ownership and population growth, the number of elderly people who own a firearm is expected to increase. In an article released by the American Journal of Public Health, Susan B.
PHILADELPHIA -- Over many generations, people living in the high-altitude regions of the Andes or on the Tibetan Plateau have adapted to life in low-oxygen conditions. Living with such a distinct and powerful selective pressure has made these populations a textbook example of evolution in action, but exactly how their genes convey a survival advantage remains an open question.
PHILADELPHIA — A tiny mountainous region in southern Siberia may have been the genetic source of the earliest Native Americans, according to new research by a University of Pennsylvania-led team of anthropologists.
PHILADELPHIA — Edward Doheny of the University of Pennsylvania has been named to the 2011 Irish Education 100 by the Irish Voice newspaper. The annual list honors leading educators of Irish descent.
Doheny is a lecturer and senior graduate advisor in Penn’s Professional Program in Applied Geoscience in the Department of Earth and Environmental Science. He traces his Irish heritage to County Waterford on his mother’s side and to County Tipperary on his father’s side.
