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.
New role for protein molecule that inhibits response of immune-system cells
Researchers at the University of Pennsylvania have identified a new role for a protein molecule that inhibits the response of immune-system cells to inflammatory signals associated with many human diseases.
Neurotoxin effectively relieves bone cancer pain in dogs, researchers find
By the time bone cancer is diagnosed in a pet dog, it is often too late to save the animal's life. Instead, the goal of treatment is to keep the dog as comfortable and free of pain as possible for as long as possible.
El Yunque rock, an icon of Puerto Rico, is eroding more slowly than expected, geologists discover
(Phys.org)—El Yunque rock is a majestic, anvil-shaped promontory that has been an icon of the island of Puerto Rico since pre-Columbian times. The barren rock, standing 3,412 feet high, protrudes above primary old growth ...
New technique allows researchers to study cell forces in 3-D
(PhysOrg.com) -- Researchers at the University of Pennsylvania have created a revolutionary new technique that will allow scientists to accurately measure the forces cells exert as they move through a three-dimensional environment.
Sex, drugs and moral goals: Study of reproductive strategies and recreational drug use
Why is there so much disagreement about whether using recreational drugs is morally wrong? A University of Pennsylvania psychology study shows that the debate about drugs might really be about sex.
Why the biological clock? Study says aging reduces centromere cohesion, disrupts reproduction
University of Pennsylvania biologists studying human reproduction have identified what is likely the major contributing factor to the maternal age-associated increase in aneuploidy, the term for an abnormal number of chromosomes ...
Moonstruck primates: Owl monkeys need moonlight as much as a biological clock for nocturnal activity
An international collaboration led by a University of Pennsylvania anthropologist has shown that environmental factors, like temperature and light, play as much of a role in the activity of traditionally nocturnal monkeys ...
The world is full of darkness, reflected in the physiology of the human retina, researchers say
Physicists and neuroscientists from the University of Pennsylvania have linked the cell structure of the retina to the light and dark contrasts of the natural world, demonstrating the likelihood that the neural pathways humans ...
A collaboration solves the herpes virus protein structure providing new drug therapy directions
The mechanism by which a herpes virus invades cells has remained a mystery to scientists, but now research from Tufts University and the University of Pennsylvania reveals the unusual structure of a key member of the protein ...
Chemists mimic library of bio-membranes for use in nanomedicine, drug delivery
An international collaboration led by chemists and engineers from the University of Pennsylvania has prepared a library of synthetic biomaterials that mimic cellular membranes and that show promise in targeted delivery of ...
