Adding a Twist Makes 3D-Printed Structures Tougher

Some mantis shrimp kill their prey with a hammer-like appendage called a dactyl club. Despite being an organism only a few inches long and weighing about as much as a deck of playing cards, the shrimp can throw shell-shattering punches at more than 50 miles per hour. If human engineers were to design a hammer […]

Penn Engineers: Bone Marrow Transplant Stem Cells Can ‘Swim’ Upstream

When a cancer patient receives a bone marrow transplant, time is of the essence. Healthy stem cells, which can restart the production of blood cells and immune system components after a patient’s own are compromised, need to make their way from the circulatory system into the bones as quickly as possible. To do that, they […]

Penn Researchers Establish Universal Signature Fundamental to How Glassy Materials Fail

Dropping a smartphone on its glass screen, which is made of atoms jammed together with no discernible order, could result in it shattering. Unlike metals and other crystalline materials, glass and many other disordered solids cannot be deformed significantly before failing and, because of their lack of crystalline order, it is difficult to predict which […]

What Can Twitter Reveal About People With ADHD? Penn Researchers Provide Answers

What can Twitter reveal about people with attention-deficit/hyperactivity disorder, or ADHD? Quite a bit about what life is like for someone with the condition, according to findings published by University of Pennsylvania researchers Sharath Chandra Guntuku and Lyle Ungar in the Journal of Attention Disorders. Twitter data might also provide clues to help facilitate more effective […]

Penn Researchers Working to Mimic Giant Clams to Enhance the Production of Biofuel

Alison Sweeney of the University of Pennsylvania has been studying giant clams since she was a postdoctoral fellow at the University of California, Santa Barbara. ​​​​​​​Sweeney, an assistant professor of physics in the Penn School of Arts and Sciences, and her collaborator Shu Yang, a professor of materials science and engineering in the School of […]

Penn Researchers Engineer Macrophages to Engulf Cancer Cells in Solid Tumors

One reason cancer is so difficult to treat is that it avoids detection by the body. Agents of the immune system are constantly checking the surfaces of cells for chemical signals that say they belong, but cancer cells express the same chemical signals as healthy ones. Without a way for the immune system to tell […]

Penn Professors Lead Call for Ethical Framework for New ‘Mind Control’ Technologies

As interventions for mental illnesses and neurological disorders are becoming increasingly powerful, an interdisciplinary group of researchers from the University of Pennsylvania, American University and Duke University are calling for new safeguards to guide treatments and protect patients.

Penn Collaboration Produces Surprising Insights Into the White Spots on Butterfly Wings

A collaboration between biologists and materials scientists at the University of Pennsylvania is yielding new insights into the wings of the “skipper butterfly” in the Costa Rican rainforest. What they learn could lead to technological advancements in systems ranging from power-efficient computer displays to sensors to energy efficient buildings, windows and vehicles.

Penn Engineers Demonstrate a ‘Hybrid Nanomanufacturing’ System

Nanoscale structures have properties that can’t be achieved in any other way, stemming from precise control over the structure’s composition and geometry. Unfortunately, simultaneously achieving high levels of control of both characteristics can be challenging. Bottom-up, self-assembly methods can carefully tailor the chemical makeup a nanoparticle, but are limited in their ability to control the […]

A $14 million grant to improve mobility and safety in transportation

Penn, in partnership with Carnegie Mellon University (CMU), is participating in a $14 million, five-year transportation research grant to establish a new national University Transportation Center (UTC) called Mobility21. The grant comes from the U.S. Department of Transportation (DoT) with the hopes of increasing both mobility and safety on the road. It is the third […]
