Penn Researchers Add Genetic Data to Archaeology and Linguistics to Get Picture of African Population History
PHILADELPHIA –- Genetic researchers from the University of Pennsylvania have combined data from existing archaeological and linguistic studies of Africa with human genetic data to shed light on the demographic history of the continent from which all human activity emerged.
The study reveals not just a clearer picture of the continent’s history but also the importance of having independent lines of evidence in the interpretation of genetic and genomic data in the reconstruction of population histories.
PHILADELPHIA –- A team of paleontologists, including a University of Pennsylvania doctoral candidate, has described a new species of dinosaur based upon an incomplete skeleton found in western New Mexico. The new species, Jeyawati rugoculus, comes from rocks that preserve a swampy forest ecosystem that thrived near the shore of a vast inland sea 91 million years ago.
The award, which honors the most important new book about America’s founding era, comes with a $50,000 prize, the nation’s largest literary award for early American history. The book was a finalist from among 62 nominees.
University of Pennsylvania and Hong Kong University Physicists Describe the Melting of Colloidal Crystal Films
PHILADELPHIA –- Physicists from the University of Pennsylvania and Hong Kong University of Science and Technology have reported an elegant experimental study of the melting behaviors of thin crystalline films, uncovering a variety of interesting differences between thick films of greater than four layers and thinner or single-layer films.
