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.
Advance in nanotech gene sequencing technique
(Phys.org) —The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical ...
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 ...
Research helps paint finer picture of massive 1700 earthquake
(Phys.org) —In 1700, a massive earthquake struck the west coast of North America. Though it was powerful enough to cause a tsunami as far as Japan, a lack of local documentation has made studying this historic ...
Researchers makes advance in nanotech gene sequencing technique
(Phys.org) —The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical ...
Research helps to show how turbulence can occur without inertia
(Phys.org) —Anyone who has flown in an airplane knows about turbulence, or when the flow of a fluid—in this case, the flow of air over the wings—becomes chaotic and unstable. For more than a century, ...
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 ...
Researchers show stem cell fate depends on 'grip'
The field of regenerative medicine holds great promise, propelled by greater understanding of how stem cells differentiate themselves into many of the body's different cell types. But clinical applications ...
Sugar triggers plants to mature to adulthood, biologists find
(Phys.org) —Like animals, plants go through several stages of development before they reach maturity. It has long been thought that some of the transitions between these stages are triggered by changes ...
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 ...
Researchers attach Lyme disease antibodies to nanotubes, paving way for diagnostic device
(Phys.org) —Early diagnosis is critical in treating Lyme disease. However, nearly one quarter of Lyme disease patients are initially misdiagnosed because currently available serological tests have poor ...
Protein 'passport' helps nanoparticles get past immune system
The body's immune system exists to identify and destroy foreign objects, whether they are bacteria, viruses, flecks of dirt or splinters. Unfortunately, nanoparticles designed to deliver drugs, and implanted ...
Geologists quantify, characterize sediment carried by Mississippi flood to Louisiana's wetlands
(Phys.org)—The spring 2011 flood on the Mississippi was among the largest floods ever, the river swelling over its banks and wreaking destruction in the surrounding areas. But a University of Pennsylvania-led study also ...
Researchers use DNA to make crystals that can switch configurations
(Phys.org)—Beyond serving as the backbone of modern biology, DNA has come to be a molecule of great interest to engineers. That a DNA sequence will naturally bind only with a complementary sequence could make it part of ...
Research show mechanism behind wear at the atomic scale
(Phys.org)—Wear is a fact of life. As surfaces rub against one another, they break down and lose their original shape. With less material to start with and functionality that often depends critically on ...
Owl monkeys who 'stay true' reproduce more than those with multiple partners, Penn study finds
Breaking up is hard to do—and can be detrimental to one's reproductive fitness, according to a new University of Pennsylvania study.
