Penn Researchers Discover New Law Guiding the Way Humans Perceive the World
September 7, 2017
Laws of perception explain why people see the world the way they do. Psychology researcher Alan Stocker discovered a new such law, confirming a link between how sensitive people are to changes in front of them, what’s called the discrimination threshold, and the perceptual bias, or the amount perception deviates from reality.
Penn Undergrad Examines Borderline Personality Disorder, Impulsive Decision-Making
September 5, 2017
This summer, Christeen Samuel, a sophomore at the University of Pennsylvania from New York City, spent 10 weeks in western Germany using technology to observe how the brain changes when a person makes an impulsive, aggressive choice, such as road rage.
University of Pennsylvania Names Calvin Bland Fellows
September 5, 2017
The University of Pennsylvania’s Penn Futures Project (PFP) has named three Calvin Bland Faculty Fellows to collaborate on research for boys and young men of color.
Penn Oral and Maxillofacial Surgeon Driven by Desire to ‘Make Someone Whole Again’
August 29, 2017
When he’s not busy in the clinic, Shanti, who joined Penn’s School of Dental Medicine as an assistant professor last year, is devoting energy in the lab to better understand what drives oral cancers and to design new structures that will more effectively replace the tissues his patients lose during surgery, whether due to cancerous or benign tumors, trauma or inflammatory conditions.
Bone Marrow Protein May Be Target for Improving Stem Cell Transplants
August 28, 2017
Bone marrow contains hematopoetic stem cells, the precursors to every blood cell type. These cells spring into action following bone marrow transplants, bone marrow injury and during systemic infection, creating new blood cells, including immune cells, in a process known as hematopoiesis.
Penn Collaboration Uses New Type of Graphene Sensor to Answer a Fundamental Nanotechnology Question
August 10, 2017
Physicists at the University of Pennsylvania have invented a new type of graphene-based sensor that could one day be used as a low-cost diagnostic system able to test for biomarker molecules, which are indicative of disease states.
Successful Guide Dogs Have ‘Tough Love’ Moms, Penn Study Finds
August 7, 2017
Much has been written of the pitfalls of being a helicopter parent, one who insulates children from adversity rather than encouraging their independence. A new study from the University of Pennsylvania seems to back up this finding — in dogs. Researchers showed that doting mothers seem to handicap their puppies, in this case reducing the likelihood of successfully completing a training program to become guide dogs.
Penn Vet Researchers Contribute Expertise to Checklist for ‘One Health’ Studies
August 4, 2017
A growing body of scientific research is focused on One Health, the integration of knowledge concerning humans, animals and the environment. Yet there is no clear, unified definition of what a One Health study is or how such a study should be conducted.
Penn Engineers Identify Protein Implicated in 3-D Epigenetics of Brain Development
August 2, 2017
The vast majority of genetic mutations that are associated with disease occur at sites in the genome that aren’t genes. These sequences of DNA don’t code for proteins themselves, but provide an additional layer of instructions that determine if and when particular genes are expressed. Researchers are only beginning to understand how the non-coding regions of the genome influence gene expression and might be disrupted in disease.
