The University of Pennsylvania (Penn) was founded in 1740 by Benjamin Franklin and is the oldest private university in the United States. Today, Penn has nearly 20,000 undergraduate and graduate students. Ben Franklin was influenced by the European model for a multi-discipline approach in higher education. Penn is noted for the Wharton School of Business, Annenberg School for Communication, School of Medicine, School of Veterinary Medicine, School of Design and School of Engineering and Applied Science. Penn is ranked alongside Cal Tech for its selective admissions and quality of undergraduate students.
Researchers use nanoscopic pores to investigate protein structure
University of Pennsylvania researchers have made strides toward a new method of gene sequencing a strand of DNA's bases are read as they are threaded through a nanoscopic hole.
Lightning reshapes rocks at the atomic level, study finds
At a rock outcropping in southern France, a jagged fracture runs along the granite. The surface in and around the crevice is discolored black, as if wet or covered in algae. But, according to a new paper coauthored by the ...
New algorithm aimed at combating science's reproducibility problem
Big data sets are important tools of modern science. Mining for correlations between millions of pieces of information can reveal vital relationships or predict future outcomes, such as risk factors for a disease or structures ...
Researchers develop a new type of gecko-like gripper
Picking things up and putting them down is a mainstay of any kind of manufacturing, but fingers, human or robotic, are not always best for the task at hand.
Study describes underlying cause of diabetes in dogs
In a new effort, researchers from the University of Pennsylvania and Baylor College of Medicine have used advanced imaging technology to fill in details about the underlying cause of canine diabetes, which until now has been ...
Evolution is unpredictable and irreversible, biologists show
Evolutionary theorist Stephen Jay Gould is famous for describing the evolution of humans and other conscious beings as a chance accident of history. If we could go back millions of years and "run the tape of life again," ...
In social networks, group boundaries promote the spread of ideas, study finds
Social networks affect every aspect of our lives, from the jobs we get and the technologies we adopt to the partners we choose and the healthiness of our lifestyles. But where do they come from?
Blacklegged tick populations have expanded via migration, biologists show
Lyme disease cases are on the rise, with diagnoses occurring in areas that were historically Lyme-free. Scientists attribute the spread to the fact that populations of blacklegged ticks, which carry the bacteria that causes ...
Engineers show how 'perfect' materials begin to fail
Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect-free materials break?
Researchers discover new chiral property of silicon, with photonic applications
By encoding information in photons via their spin, "photonic" computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information in the spin of electrons, rather ...
