Penn Researchers Lay Fundamental Groundwork to Better Understanding Optical Properties of Glass
September 13, 2017
Glass is everywhere. Whether someone is gazing out a window or scrolling through a smartphone, odds are that there is a layer of glass between them and whatever it is they’re looking at. Despite being around for at least 5,000 years, there is still a lot that is unknown about this material, such as how certain glasses form and how they achieve certain properties. Better understanding of this could lead to innovations in technology, such as scratch-free coatings and glass with different mechanical properties.
Penn Engineers Develop the “WorMotel,” Simultaneously Study the Aging Process in Thousands of Model Organisms
September 11, 2017
The roundworm C. elegans is one of the most important model organisms in biological research. With a transparent, millimeter-long body containing only about a thousand cells and a lifespan of a few weeks, there is no better way of deciphering the role of a given gene on a living creature’s anatomy or behavior. In addition, many of the genes discovered in the worm have been shown to have similar roles in other animals and humans.
Penn: How Openings in Antarctic Sea Ice Affect Worldwide Climate
September 11, 2017
In 1974, images acquired from NOAA satellites revealed a puzzling phenomenon: a 250,000 square kilometer opening in the winter sea ice in the Weddell Sea, south of South America. The opening, known as a polynya, persisted over three winters. Such expansive ice-free areas in the ocean surrounding Antarctica have not been seen since, though a small polynya was seen last year.
Penn Summer Program in STEM Teaches Middle Schoolers to Overcome Communication Barriers
September 11, 2017
Mark Licurse didn’t know what to expect when he decided to group together middle schoolers from two very different schools for a week-long STEM Summer Science Camp held by the Laboratory for Research on the Structure of Matter at the University of Pennsylvania.
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.
Hurricane Season and Relief Efforts: Expert Comment From the University of Pennsylvania
August 31, 2017
Note for TV and radio: The University of Pennsylvania has an on-campus satellite uplink facility with live-shot capability and an on-campus ISDN line.
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.
Shrinking Swiss Glaciers Inspire Undergraduate Student’s Energy Research at Penn
August 28, 2017
By Erica Andersen Yann Pfitzer spent the heat of a Philadelphia summer in a lab, designing and testing ultrathin plates that could one day be part of systems that convert extreme heat to electricity.
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.
