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.
'Onion' vesicles for drug delivery developed
One of the defining features of cells is their membranes. Each cell's repository of DNA and protein-making machinery must be kept stable and secure from invaders and toxins. Scientists have attempted to replicate these properties, ...
Two-photon microscopy: New research may help drastically reduce cost of powerful microscope technique
(Phys.org) —A dye-based imaging technique known as two-photon microscopy can produce pictures of active neural structures in much finer detail than functional magnetic resonance imaging, or fMRI, but it requires powerful ...
New biomolecular archaeological evidence points to the beginnings of viniculture in France
France is renowned the world over as a leader in the crafts of viticulture and winemaking—but the beginnings of French viniculture have been largely unknown, until now.
Deep ocean current may slow due to climate change
(Phys.org) —Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe.
Owl monkeys don't cheat, study shows
True monogamy is rare in the animal kingdom. Even in species that appear to "mate for life," genetic maternity and paternity tests have revealed that philandering often takes place.
Computer users circumvent password security with workarounds, according to study
(Phys.org) —When workers and organizations circumvent computer passwords and security rules, they unwittingly open the door to hackers, according to a study co-authored by Ross Koppel, an adjunct professor of sociology ...
Engineers enable 'bulk' silicon to emit visible light for the first time
Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass those limitations, ...
Engineers' nanoantennas improve infrared sensing
(Phys.org) —A team of University of Pennsylvania engineers has used a pattern of nanoantennas to develop a new way of turning infrared light into mechanical action, opening the door to more sensitive infrared cameras and ...
Plant hormone has dual role in triggering flower formation, study finds
Flowers aren't just pretty to look at, they are how plants reproduce. In agricultural plants, the timing and regulation of flower formation has economic significance, affecting a crop's yield.
Researchers model a key breaking point involved in traumatic brain injury
(Phys.org) —Even the mildest form of a traumatic brain injury, better known as a concussion, can deal permanent, irreparable damage. Now, an interdisciplinary team of researchers at the University of Pennsylvania is using ...
