Penn Engineers’ ‘Photonic Doping’ Makes Class of Metamaterials Easier to Fabricate
The field of metamaterials, an intersection of materials science, physics, nanotechnology and electrical engineering, aims to produce structures with unusual electromagnetic properties. Through the careful combination of multiple materials in a precise periodic arrangement, the resulting metamaterials exhibit properties that otherwise couldn’t exist, such as a negative index of refraction.
Penn-led Project Investigating the History of the Universe Receives $700,000 NASA Grant
A University of Pennsylvania-led project, the Spectroscopic Terahertz Airborne Receiver for Far-InfraRed Exploration, or STARFIRE, has received a $700,000 grant from NASA to investigate a longstanding mystery in cosmology.
Penn Researchers Push the Limits of Organic Synthesis
A dendritic molecule is one that grows by branching in several directions from its center core. At each branching point, the molecule branches again into a new generation. These molecules can be used for a broad range of biomedical applications, including gene and drug delivery.
Penn Engineering Offers an Online MicroMasters in Robotics
Beginning in April, Penn Engineering and the GRASP Laboratory will offer a new series of online courses in robotics as part of edX’s “MicroMasters” program.
Penn Researchers Apply a Phenomenon in Proteins to a Mechanical Network
Researchers at the University of Pennsylvania are investigating a counterintuitive process called allostery that occurs in proteins by studying an analogous process in a macroscopic mechanical network.
Penn Vet Team Identifies New Therapeutic Targets for the Tropical Disease Leishmaniasis
Each year, about 2 million people contract leishmaniasis, a parasitic disease transmitted by the bite of a sand fly. The cutaneous form of the disease results in disfiguring skin ulcers that may take months or years to heal and in rare cases can become metastatic, causing major tissue damage.
Tired Teens More Likely to Commit Crimes as Adults
Teenagers who self-report feeling drowsy mid-afternoon also tend to exhibit more anti-social behavior such as lying, cheating, stealing and fighting.
Researchers Gain Insight Into a Physical Phenomenon That Leads to Earthquakes
Scientists have gotten better at predicting where earthquakes will occur, but they’re still in the dark about when they will strike and how devastating they will be.
Penn Engineers Overcome a Hurdle in Growing a Revolutionary Optical Metamaterial
When John Crocker, a professor of chemical and biomolecular engineering in the University of Pennsylvania’s School of Engineering and Applied Science was a graduate student, his advisor gathered together everyone in his lab to “throw down the gauntlet” on a new challenge in the field.
T Cells Support Long-lived Antibody-producing Cells, Penn-led Team Finds
If you’ve ever wondered how a vaccine given decades ago can still protect against infection, you have your plasma cells to thank. Plasma cells are long-lived B cells that reside in the bone marrow and churn out antibodies against previously encountered vaccines or pathogens.
